Paving slabs are used to lay paths in summer cottages and cottages, and paths in the garden. Neatly tiled paths give a well-groomed look to any country house. It is better to purchase the product in construction markets or make it yourself. For self-made you will need mold release agent paving slabs. You can also prepare it yourself or purchase it at hardware stores.

Various options

The tile covering is made of concrete and can have different structures:

• universal;
• rectangular;
• arbitrary;
• castle;
• model.

There are two options for making the product - under pressure and casting. The first method is quite heavy, and the second can be used for self-production. The composition of the product is also varied:

• cement with sand;
• fired clay;
• rubber;
• plastic;
• granite.

Most often, cement is used as the basis for the product. This durable material, practically indeformable during prolonged use. All that remains is to find out how to lubricate the molds for paving slabs.

DIY recipe

Regardless of the type of tile product chosen, the process will require a lubricant. The recipe for lubricant for paving slab molds is as follows:

1. motor oil (50 g);
2. water (1.5 l.);
3. dilute the oil with water;
4. the mixture must be stirred very thoroughly;
5. Make sure that the composition is not too greasy, otherwise you will end up with a low-quality product;
6. a non-concentrated composition is also not suitable.

When the lubricant is ready, you can start cooking concrete mixture. You will need a concrete mixer. If a multi-colored option is needed, then add to the concrete mixture acrylic paints. You can also make the molds yourself, especially if you want something unusual. They are made from wooden blocks. Special stencils are sold for applying the design.

Lubricant properties

Lubricate the molds for production before pouring. Do-it-yourself lubricant for paving slab molds has the following properties:

• high-quality composition does not spoil the color and shape;
• there are no pores allowing air to pass through;
• the composition can be diluted with water;
• the finished tile can be removed from the mold without any problems;
• a thin layer of composition is required;
• no need to purchase special clothing.

The lubricant is applied with an ordinary sponge. The forms in which the products are prepared usually do not have heavy pollution. The lubricating solution does not require special skills or costs to prepare.

Types of lubricants

There are several types for lubricating molds with different properties:

Almost all mixtures are concentrated. This is good because you can cook a lot ready-made composition. Add water to the concentrate and mix thoroughly until a homogeneous consistency is obtained.

How to lubricate?

To get a quality product, you need to know how to coat molds for paving slabs. Be sure to clean the molds before starting work. There should be no debris or any contamination left in them.

Important: lubricant for paving slabs is applied only before pouring the concrete mixture. The mixture is applied to the walls thin layer. You can use a brush, sponge, spray. The tool depends on the composition lubricant. You will only need gloves to protect your hands.

Observe the following rules:

1. tile molds should be lubricated so that there are no gaps;
2. make sure that no brush bristles get into the molds;
3. You can clean the molds with a solution based on hydrochloric acid (diluted with water).

It’s easier to clean with soap and water. You need to mix the soap with any dishwashing detergent.

Thanks to the preliminary application of lubricant to the molds, we get the following result:

• the product can be easily removed;
• formwork and forms are easy to clean;
• The original shape is preserved because it can be easily removed.

Lubricate the plastic

Grease for plastic molds of paving slabs is also applied before pouring. Each mold needs to be processed separately. The compositions do not require work in special clothing, thanks to environmentally friendly components.

Advantages of a lubricant composition based on biodegradable components:

• safety at work;
• economical;
• mixes with water;
• does not affect the rate of hardening of the concrete mixture.

Another advantage to using emulsol as a lubricant is frost resistance.

When diluting concentrates with water, make sure that the mixture is homogeneous. Silicone lubricant for paving slab molds has good water-repellent properties. Most often it is used in the manufacture of large tiles. Can process plastic and metal molds.

Fill

The forms are greased, all that remains is to fill them with concrete. The work requires compliance with certain rules:

• It is better to use a vibrating table. Do not weaken, try not to overload the springs;
• Large tiles are made in two steps. First, they fill it to the middle, then the reinforcement is placed. The final stage is complete filling.

When making products with your own hands, lubricant for paving slabs plays an important role. After finishing the work, the product literally jumps out of the mold without additional effort.

The secret of beautiful tiles

To make paths and sidewalks at your dacha look beautiful, you need to know how best to lubricate molds for paving slabs. Lubricating compounds make the entire tile production process much easier.

Thanks to the proper use of lubricants, the molds remain in working order. long time. Depending on the structure of the composition, it may be enough for large number molds. Preparing the mixture will take time, but will pay off in the process of making the tiles and subsequent cleaning of the molds. A properly prepared lubricant allows you to remove finished products from molds without deformation. Lubrication also affects the color of the product.

Follow the main rule: the molds are not filled with grease, but rather lubricated.

Let's compare the efficiency

Cheap, readily available components can also be used as lubricating solutions. Let's look at how they behave during operation:

Which composition will be better depends on the quantity of the product produced. Therefore, if the sidewalk paths are not several kilometers long, then there is no need to spend extra money. Try homemade options for making lubricating solutions.

Regardless of what lubricant you use during the process, you should not leave finished products in the molds for a long time. The deadline when the product can be removed without problems is three days. If you leave it longer, it will be difficult to wash the molds.

How to avoid bubbles?

Lubricating mixtures help not only to safely remove the finished product. This way you can avoid the formation of bubbles on the surface of the tiles.

Bubbles usually form on the face of the tile. It looks very ugly. This is why it is so important to pre-apply a lubricant before pouring concrete.

To improve the quality and effect of the lubricant composition, add a plasticizer to it. This action will prevent the appearance of bubbles.

Cement affects the quality of tiles. The material must be fresh, not stale. Pay attention to the cost of cement, and it’s better not to save money. It is advisable to purchase cement in large construction stores, where you can check the contents of the material.

To give the tiles the required color, try to dilute the dyes in advance. It’s good if the diluted solution remains for half a day. Don’t be afraid to leave the dyes for so long, they won’t deteriorate and the structure won’t be deformed.

The range of lubricants, emulsions, concentrates, various petroleum oils, as well as powder and soap solutions used is extremely wide. The choice of lubricant largely depends on the manufacturer, formwork configuration and production volume. The most popular lubricants are based on various concentrates and, in particular, KSF-1. Low consumption square meter, the possibility of application with any means at hand, make this product interesting from a material point of view.

As a rule, types of lubricants do not affect or change the color of the cast product, and do not have a destructive effect on the shape of paving slabs. If they are produced in small quantities, for example, for summer cottages, yard or street paving, the lubricant can be purchased at a service station for free. But remember that the lubricant must be applied to a completely clean surface.

Krystal molding grades of oils are also widespread. Based on them, emulsions are formed, which are applied by spraying. Used in the production of a wide range of paving and facing slabs, decorative pillars, laying lawn fences, borders and others.

Nometal lubricant is also of interest. This type of oil not only facilitates the separation of the concrete product from the formwork, but also protects the metal form from corrosion. Lubrication gives:

• high-quality appearance of the external surface of the product;
• prevents the appearance of pores on the front part of the product;
• Easily separates the finished slab from any type of mold.

You can lubricate the forms of paving slabs with the so-called anti-adhesive concentrate. It is used for polymer and metal molds in the production of large-sized slabs. The properties of such a lubricant give the surface of the product water-repellent qualities with the formation of a film; it differs from other lubricants in its independence from temperature changes.

It should be borne in mind that lubricants are highly soluble in water, which makes it possible to obtain 100 or more liters of lubricant from 10 kilograms of concentrate. This especially applies to concentrates like KSF-1. A homogeneous lubricating solution is obtained after 4-5 minutes of stirring.

We should not forget about the AGAT series lubricant. This generation of highly effective lubricant is used for all types of formwork. The most economical, since 1 liter of lubricant is enough to process 35 square meters. surfaces.

In general, lubricants are not harmful to health and have no impact on the environment.

The issue of lubricating paving slab molds is not considered problematic due to the presence of their variety, including homemade ones.

Lubricant for paving slab molds does not work last role in the production of tile products. Of course, concrete mortar, dyes, plasticizers and the right technology directly determine the quality of future tile products. Good lubrication makes it easier to remove products from molds and maintain (or even improve) their appearance. Moreover, it prevents the appearance of pores on front side paving slabs and paving stones.

For high-quality styling tiles, it is necessary to carefully prepare the molds for its manufacture.

Before pouring concrete into molds, they must be thoroughly cleaned and lubricated. By the way, they are made from various materials and there are metal, plastic, polyurethane, wood (formwork).

High-quality lubricant does not affect the shape, does not change the color of the cast tile and does not have a destructive effect on it.

The choice is quite diverse: all kinds of emulsions, powder and soap solutions, mineral oil concentrates, etc.

Variety of mold release agents

To produce a small volume of tile coverings, you can contact the nearest service station and purchase lubricant for a nominal price or for free. For large volumes of tiles and paving stones, special domestic and foreign lubricants are used. We list the most popular and frequently used in the manufacture of paving slabs and paving stones:

At home, you can make lubricant based on motor oil.

1. KSF-1. Available in the form of a homogeneous paste, it is characterized by low consumption, ease of application, provides an even, smooth surface and does not leave colored spots on it. The lubricant is non-toxic and dissolves well in cold and warm water. Used as an emulsol - 9-10% aqueous solution. You can lubricate the molds with any means at hand. Used for plastic, metal forms and formwork.
2. Kristal, based on light mineral oils, is an environmentally friendly product, has excellent anti-corrosion properties, and is used for metal and wooden forms. Apply with a brush or spray.
3. Nometal also protects metal forms from corrosion, cracks and pores.
4. Agate, used for any shape, is a very economical lubricant, allowing 1 liter to cover 35 square meters. m. surface, has many positive reviews.
5. Anti-adhesive concentrate Tiprom 90 based on silicones, which has water-repellent properties, is usually used for the production of large slabs in metal and polymer forms. Does not respond to temperature.
6. Emulsol, made on a mineral basis, is often used in construction to lubricate formwork. Consists of biodegradable substances. It is applied with a sponge or spray, is quite affordable and is very suitable for the manufacture of paving slabs, without requiring subsequent grouting or finishing.

Many lubricants are available in the form of concentrates. Concentrates differ in that you can get more of the finished product from them. To do this, add them to water and stir for 5 minutes.

How is lubricant applied and is it possible to save money on it?

For easy removal of paving stones, the mold must be lubricated.

Apply a thin layer of lubricant to each mold with a brush or spray, depending on the selected lubricant. Before application, as already mentioned, you need to thoroughly clean the molds of debris and dirt. They need to be lubricated immediately before pouring concrete. No special clothing is required to apply the lubricant. It is enough to wear gloves to protect your hands from contamination. If the spraying method is chosen, it is better to wear a respirator.

When applying with a brush, you need to ensure that all corners are treated and the bristles do not remain in shape. Any little thing can ruin appearance tiles

It should be noted that lubricant not only improves the process of removing tiles, but also significantly extends the service life of the molds, reducing the load on them.

Now here is a recipe for a simple and cheap DIY lubricant. Take 50 g of motor oil and dilute it in 1.5 liters of water. Shake it up. This needs to be done for quite a long time. We test on the product. You can experiment with proportions. A greasy lubricant can create pits in the tiles or oil stains on the surface, while a weak lubricant will worsen the removal process.

Some tilers use it to rinse molds. brine. Hydrochloric acid diluted with water, and forms are lowered into a 7-10% solution. Then they don't lubricate.

Some people use soapy water. It is prepared from ordinary soap or dishwashing liquid. Naturally, the savings are obvious, and the slipping of the tiles out of the molds will also please you, but they remain very dirty after it.

To summarize, let us once again outline the three main functions of a release agent:

• easier removal of products:
• reducing labor costs for cleaning molds and formwork;
• maintaining the quality of products and their appearance due to the fact that the concrete does not stick to the form and the tiles do not have to be “torn off”.

By saving on lubricant, you can lose much more on discarding. Even when producing tiles for their own needs, everyone wants them to be beautiful, strong and durable.

For many country property owners topical issue What remains is the technology for making paving slabs with your own hands.

Indeed, if you acquire certain skills in working with paving stones, you can transform your garden area beyond recognition, make a hard surface in the yard or install garden paths.

• Manufacturing methods
• Which one is better
• Special tools
• Types of forms
• Preparation of the solution
• Manufacturing cost calculation

Manufacturing methods

In practice, two main methods are used. First, let's get acquainted with the nuances of obtaining the material in question using the vibration casting method. This method is characterized by its comparative cheapness and the possibility of obtaining high-quality building materials even by inexperienced workers.

The technology for producing the material is as follows. The prepared working solution is poured into greased molds. Next, they are installed on a vibropress and compacted until air bubbles are released. Next, the raw material is placed on special racks for drying. After about two days, the tiles are knocked out of the molds and reused.

Paving stones made by vibrocompression differ from their analogues in improved resistance to mechanical stress and high strength. Such materials are intended for laying coatings in critical places, for example, car parks.

Please note: you can only make vibro-cast paving stones with your own hands, which can be used for constructing garden paths. Homemade materials cannot be used for a long time as a covering in places where vehicles are moving or parked.

The technology for producing vibropressed tiles is somewhat reminiscent of the work on producing tiles using the vibration casting method. Ready solution passes through a special press, so the products have improved strength indicators. At the final stage of work, the material is dried in special steaming chambers.

Which one is better

According to most consumers, approximately 80% of total number respondents, best performance have materials that were obtained in a factory using the vibration pressing method.

Such products are slightly more expensive, about 20%, but they are much more durable. The concrete mixture has a more dense structure and has fewer pores, which improves the frost resistance and abrasion properties of the surface.

It is important to know: pressed paving stones, which are available in hardware stores, are limited in shapes and shades; cast tiles, on the contrary, have many different shapes and colors.

The maximum destructive effects occur with the coating in winter time year, when water gets inside the concrete, it expands and destroys its structure. The surface of materials made by vibration casting can be protected by introducing special water-repellent substances into the base composition, but such elements will not make it last forever, but will only increase its service life.

Special tools

To obtain the materials in question, you need the following tool:

• Concrete mixer of a certain volume.
• Factory or homemade vibration table.
• Rack for laying forms of paving slabs (used as a dryer). Drying of raw materials will take place in this place. The initial process takes two or three days, then the paving stones are knocked out of the mold and laid to dry for another month.

Good to know: a similar unit is used to remove air bubbles from the concrete mixture during compaction.

• Containers for warm water. In them, products are removed from the formwork;
• Matrices or forms. They can be made from scrap materials or ordered from online stores.

One of the most popular forms for paving stones is silicone. Such products are used to create complex shapes. Such formwork allows you to obtain a pattern with a different textured surface.

The disadvantage of the product is considered to be limited use (no more than 50 cycles). Subsequently, the shape loses its original geometric dimensions.

The next type, plastic formwork, is used to obtain simple products. The main advantages of such structures are considered to be high levels of durability and strength. Such products can withstand up to 800 cycles of pouring and hardening of the working mixture.

Forms based on polyurethane are somewhat similar to silicone formwork, but they are more expensive and have a longer service life (up to 100 cycles).

Many private developers are interested in the question of how to make a form for paving stones themselves. The most popular option is wooden formwork, made from pieces of plywood or thin boards.

Please note: when making molds, take into account internal dimensions, which will correspond to the dimensions finished product.

Such shapes are made in the form of a square or rectangle, as well as a hexagon. At the junction of adjacent elements, fix metal corners.

Preparation of the solution

The basic composition of the paving mortar must contain the following components:

• 21% binder (cementm500);
• 55% sand purified from large impurities;
• 24% of granotsev;
• 0.7% plasticizer (you can take grade C-3);
• 7% pigment dye
• reinforcing fiber 0.05%;
• 5.5% water.

This is interesting: from one cubic meter working solution, you can make 16 m2 of tiles, provided that its thickness is 6 centimeters.

To obtain a high-quality mixture, it is necessary to mix all of the specified raw materials in a concrete mixer. First you need to dissolve the plasticizer with a small amount of warm water and pour it into the mixer. The drum of the unit rotates until the plasticizer is completely dissolved in the liquid.

The pigment dye is also mixed with water heated to 80 degrees until completely dissolved; these components of the mixture are taken in a ratio of 1 to 3. After pouring the required amount of water into the concrete mixer, sand and crushed stone are added alternately, then a binder (cement). For effective mixing, water is periodically added to the raw materials. The last time this is done is at the end of the batch.

Step-by-step description of the process at home

First you need to properly prepare the forms. For this they inner surface coated with mining or other type of lubricant.

At the formation stage, it is necessary to pour the prepared solution into the molds. If there is a need to produce material with a colored surface, then 75% of the formwork is filled with ordinary gray concrete, the remaining 25% with colored concrete. In this case, the decorative part of the product should be at the bottom.

Forms filled to the top with the solution are gently shaken and placed on a vibrating table for about 5 minutes. The products are removed from the table after a white film appears on the surface. Whiteness usually indicates the release of air bubbles from the concrete. When making two-color paving stones, each layer is compacted separately.

Expert advice: if oil is applied generously, small depressions may form on the surface of the tile, but if there is not enough lubrication, it will be difficult to pull the paving stones out of the mold.

The next stage of work, drying, involves placing the products on racks for a period of up to three days. The drying room must be equipped exhaust ventilation. In addition to the storage warehouse finished products The sun's rays should not penetrate. To reduce the intensity of moisture evaporation from the surface of the material, the form with concrete is covered with a transparent plastic film.

The final stage is removing the tiles from the mold. This process is carried out in a special container with water heated to 60 degrees. Under the influence of heat, the mold expands, as a result of which the tiles are removed without any problems. The product is knocked out onto a soft mat and placed to dry for another month (for final hardening).

Manufacturing cost calculation

Price calculation is necessary if this material will be used for subsequent sale, as well as to determine the savings between do-it-yourself paving stones and factory-made products.

The main money will have to be paid for the raw components of the concrete mixture and formwork. Here are approximate prices:

• 50 kilogram bag of Portland cement grade 500 - 400 rubles;
• Fine crushed stone – 1750 rubles per m3;
• Sand purified from harmful impurities – 600 rubles per m3;
• Pigment dye - about 5000 rubles for a 25 kilogram bag;
• Plasticizer grade S-3 up to 80 rubles per liter;
• Lubrication within 100 rubles. Per liter;
• The cost of the molds depends on the dimensions and material of manufacture, ranging from 30 to 1500 rubles.

The price of ordinary tiles with a smooth surface starts from 200 rubles/m2, textured tiles are even more expensive - approximately 450 rubles/m2. If you carefully calculate all the costs, then paving stones made at home will cost 10-30% less than factory-made products.

How to make colored paving slabs

There are several ways to make colored paving stones at home. Let's describe the most popular of them:

1. Addition of pigment dye to the base composition of the mixture. After mixing the raw materials, concrete can be obtained desired color.
2. The second option for painting tiles is to apply color to the inner surface of the mold. The acquisition of the selected color by the material occurs after direct contact of the concrete mixture with the pigment dye.
3. Finished materials are painted using a spray gun.

Keep in mind: mixing multiple colors creates a more interesting texture for your items.

As we can see, the process of making paving slabs at home is quite simple. If you become familiar with the production technology and have at least a little desire, you can make a hard surface in the yard of a private house and even make money by selling paving stones.

Mold lubricants for concrete

To give your yard or garden a neat and finished look, you can fill it with concrete, but it will look much more aesthetically pleasing if you lay it out with tiles or paving stones. You can buy ready-made material, but there is also the option of making it yourself in special forms. This requires a concrete solution and a special lubricant, the purpose and properties of which will be discussed below.

Benefits of using lubricants

Tiles are small concrete pieces that are used to lay the covering on paths. It happens different shapes and colors, made from different materials. But for the production of each of them, a lubricant is used. Concrete and various additives will play a role main role as tiles, but mold lubrication is also important. It is used to remove tiles to preserve their appearance. In addition, it reduces the likelihood of pores forming on the outside of the tile.

Before pouring the concrete solution into the mold, it must be cleaned of dust and debris and lubricated. Such forms are made from metal, plastic, polyurethane or wood. If the lubricant good quality, it does not affect the tile in any way, neither the shape nor the color. Such lubricants are produced in the form of emulsions, powder and soap solutions, oil concentrates, etc. The sample is coated with a thin layer of lubricant, and no special clothing is needed.

Species

Lubricants are primarily classified into:

• made from improvised materials;
• specialized.

What they have in common is that they help remove tiles.

Made from improvised materials

Types and their main characteristics:

• saline solution - diluted with water, low price, possibly causing stains that are difficult to clean;
• motor oil– it is applied with a sponge, cheap, easy to wash off the sample, can affect the color of the tile;
• Soap solution is liquid soap, it is used to lubricate the walls; it is not easy to wash samples.

Lubricants from improvised means are especially relevant when producing small quantities of paving stones, when purchasing a special liquid is impractical. In such cases, you can go to a transport service station and buy a small amount of the product.

Specialized

If you need to lubricate many molds to produce large batches of tiles, you will need to purchase special remedy. They come in different brands, so finding one won't be a problem.

• Kristal - the basis of this lubricant is light mineral oils. They are environmentally friendly and have anti-corrosion properties. The material is used for samples made of metal or wood. Application is possible either with a brush or with a spray;
• KSF-1. It has the form of a homogeneous paste. It is economical to use and easy to apply. With its help, it turns out smooth and smooth surface. The material is environmentally friendly, washes off with water. Easy to apply to plastic, metal and wood forms;
• Tiprom 90 (concentrated anti-adhesion liquid). The basis of this solution is silicones, which tend to repel water. More often used for lubricating molds (made of metal or polymer) in the manufacture of large slabs. Temperature resistant;
• Nometal. Used to protect metal forms from corrosion and cracks;
• Emulsol – made on the basis of mineral substances. Used for formwork. Apply with a sponge or spray. It's inexpensive. Used in the manufacture of paving slabs, as there is no need for grouting;
• Agate is an economical product to use, as it has low consumption.

Lubricants are produced in concentrated solutions that must be diluted with water.

Examples of manufacturers

Lubricants are produced by many manufacturers in the most different countries. Examples:

• Italy: PTFE, DMA 1000;
• Russia: "Miskom";
• Ukraine: GOI-54P, “Budforma”.

How is the lubricant applied?

The solution is applied using a brush or spray to each mold. Before this, they are cleaned of dust and debris. Before pouring concrete, a lubricating mixture is applied. There is no need for protective suits. Wear gloves, but only to protect your hands from dirt. When spraying, it is advisable to wear a respirator. It is necessary to process the form carefully, not missing corners and crevices. The use of such a solution increases the service life.

Conclusion

Lubricating concrete molds – important stage in the production of tiles and paving stones. With its help, it is easier to extract concrete from samples and improves the appearance of the tiles. Lubrication is necessary to extend the life of the mold. For these purposes, you can use special purchased solutions or homemade mixtures.

How to lubricate the mold for paving slabs

High-quality paving slabs should be streak-free and practically perfect shape. And the point here is not only in the solution, but also in the lubricant for the molds. High-quality lubricant prevents concrete from sticking on plastic forms. Then the question arises: what is the best way to lubricate the mold for paving slabs?

Types of lubricants and their advantages.

One of the most commonly used lubricants is soap solution. Liquid soap is applied with a brush to the inner surface of the mold before filling it with solution. The advantage of this method is that the finished tile simply slides out of the mold. The disadvantages include significant contamination of the form.

Motor oil is also suitable for lubricating molds. The advantage is good slippage, but streaks may remain on the surface.

When using saline solution, the form must be completely immersed in it. However, with this method, salty traces remain in the finished product.

Practically ideal option can be called a formwork lubricant, which is sold in any hardware store. This product does not leave marks on tiles and forms.

You need to choose what to lubricate the mold for paving slabs depending on individual preferences, having thoroughly analyzed all the advantages and disadvantages.

Do-it-yourself paving slabs - making concrete tiles for paths at home: technology, solution, forms, photos

Paving slabs - simple and reliable way arrange a garden path, path, driveway at the dacha or lay out a platform in the courtyard of a private house. Depending on the place of application, different requirements are imposed on the tiled covering of paths regarding strength and installation method.

One of the factors that determines the longevity of a tile walkway is the installation solution. However, many people prefer to make paving slabs with their own hands.

Vibro-pressed or vibro-cast tiles

From the point of view of industrial manufacturing technology, tiles can be made in two ways:

Vibrating table for the production of vibro-cast paving slabs Vibrating-cast paving slabs (cheaper, used in private construction).

Manufacturing technology: concrete solution is poured into molds that are placed on a vibrating surface. During vibration, the solution evenly fills the mold and air bubbles come out of it. Afterwards, the forms are placed on drying racks. After 2-3 days, the tiles are removed and dried.

Production line for vibro-pressed paving slabs Vibro-pressed paving slabs (more resistant, designed for use in places with intense load).

The production technology is similar, but the solution is additionally pressed with a press (vibropress). The result is a more compacted mixture and, accordingly, a stronger material structure. The tiles are dried in special chambers.

You can only make vibro-cast tiles for paths and paths yourself. Let us immediately focus your attention - homemade paving slabs are not intended for laying in areas of heavy traffic, but will become indispensable for forming garden paths in the country.

Which paving slabs are better – vibro-cast or vibro-pressed?

According to reviews on the forums, 80% of users agree that the best paving slabs are those that are manufactured in a factory using vibrocompression. It's more expensive (

20%), but more durable. The point is that the resulting concrete is more dense and has fewer pores; therefore, the tiles absorb little water, do not crumble and are resistant to abrasion.

But pressed tiles have a limited choice of colors and shapes, while cast tiles, on the contrary, are easy to manufacture, which means they are more affordable, plus, you can cast almost any shape, and large selection shades.

The tiles are subject to the greatest damage in winter, when water that gets inside the concrete freezes and expands. Of course, you can protect vibrocast tiles hydrophobic compounds, but this will not make it eternal; the service life is shorter than that of a pressed one. However, for private use on a limited budget, you can get by with homemade paving slabs.

How to distinguish vibro-cast tiles from vibro-pressed ones?

Visually. The first will have a heterogeneous smooth structure, the second will have a homogeneous, rough structure. Paradoxically, the vibration-cast one is more beautiful in appearance (at the time of sale) - bright, smooth (examples in the photo). The difference manifests itself during operation.

Advantages of paving slabs

Why did paving slabs become popular, leaving asphalt, concrete and bulk (gravel) paths far behind? Because paving slabs for paths in the country have a number of advantages over other types of coating:

Moisture permeability tile covering– moisture and vapor permeability of the coating. Under the path made of tiles, natural microflora is preserved, and moisture evaporation occurs as when loosening the soil, i.e. more uniform. This does not interfere with the growth of the roots of shrubs and trees, and plants growing along the garden path last longer without watering;

Beautiful paths from paving slabs – aesthetics. Thanks to the different shapes and colors of the tiles, you can make a beautiful design (lay out an ornament, pattern) on country path;

Repair of paving slabs - maintainability and the ability to replace, move concrete tiles if necessary;

Paths made of tiles with a complex pattern - the ability to create paths of a complex configuration with your own hands.

There are two ways to obtain tiles for sidewalks and walkways.

• First, buy ready-made paving slabs. Less hassle, faster, simpler and not much more expensive. But no one is immune from counterfeit in this industry, and making paving slabs with your own hands gives you confidence in its quality.

• Secondly, do it yourself. We will consider this method in detail, starting with the material and ending with unmolding.

Material for making paving slabs

You can’t make a quality product from just anything. Therefore, in the listing process we will focus on the properties of the material and the requirements for them.

1. Cement

Determines the quality of the tile. What cement should I use for paving slabs? To make the solution, you need high grade cement (M400 is a minimum, ideally M500). The grade of cement indicates its compressive strength. Accordingly, the higher the grade of cement, the stronger the concrete solution, which is the basis for the recipe for the production of paving slabs. The use of M-500 cement will give the tiles such properties as frost resistance, strength and water resistance.

Only fresh cement is suitable for making tiles (during a month of storage, cement loses 5% of its properties). You can check the quality of cement by squeezing a handful of powder in your fist. If it leaks through your fingers, the material is fresh; if it clumps into a lump, it’s better not to buy it.

Note. You should not try to save money by purchasing the M 300 brand, because... in this case, cement consumption will increase significantly.

2. Filler for cement (concrete) mortar

• large filler. Screenings, small crushed stone, slag or pebbles are used as filler. They must be clean to work.

• fine filler. This includes sand of fraction 0.4-0.6 mm. It is important that it does not contain impurities and clay.

3. Water

For solution used drinking water room temperature.

4. Plasticizer for the production of paving slabs

Sold in powder or ready-mixed form. Why do you need a plasticizer? Designed to communicate to the solution additional properties, reducing the consumption of cement and water, increasing the density of concrete, facilitating the process of mixing the solution.

Which plasticizer is better for paving slabs?

Plasticizer for the production of paving slabs Good reviews deserved: Westplast, PLASTIMIX F, POLIPLAST SP-1, Master Silk. But the best (popular among users) is the additive Superplasticizer S-3.

Adding a plasticizer to the concrete solution guarantees low abrasion of the tiles and their moisture and frost resistance.

5. Dye for paving slabs (pigment)

Dye for paving slabs The paint allows you to create tiles of different colors. It is important that the coloring pigments are lightfast. Considering the high price of dyes (from 1500 to 8600 thousand rubles), two-color paving slabs are in demand. IN top layer dye is added, the bottom one remains gray.

6. Fiber fiber (reinforcing fiber)

Fiber for concrete is needed to increase the strength of the tiles. Polypropylene fiber is used to reinforce concrete (fibers up to 20 mm long and 10-50 microns in diameter).

Fiber for concrete For example, polypropylene fiber Micronix 12mm. (RUB 165.00/kg), chopped glass fiber (RUB 145.00/kg) or basalt fiber MicronixBazalt 12mm (RUB 98.00/kg) (in order in the picture).

Note. The length of the fiber should not exceed the diameter of the largest aggregate in the concrete solution.

7. Lubricant for paving slab molds

You can buy a special lubricant for molds, for example, Lirossin (Ukraine, 210 rubles/5 l.). This is a concentrate that is diluted with water in a ratio of 1:10. Or Emulsol (Russia, 175 and 40 kg barrel, sold on tap for 38 rubles/l).

How to lubricate molds for paving slabs at home?

Users advise not to spend money on industrial lubricants, but to use analogues (substitutes):

• motor oil (can be used);

• soap solution. The cheapest solution from water and detergent, which facilitates quick removal of tiles from the mold;

• sunflower (vegetable) oil.

Some craftsmen use a saline solution, but it leaves salt stains on the tiles, and silicone and plastic molds quickly become unusable. Others suggest covering the mold with two layers of varnish. This coating will ensure easy sliding of the tiles. But, this method is applicable only for plastic forms, plus, the varnish quickly deforms, which will affect the quality of the sides and front surface of the tile.

Tools and equipment for making paving slabs

Depends on the quantity of tiles being produced.

1. Concrete mixer. With a minimum amount of work, it can be replaced with a trowel or shovel.

2. Vibrating table for paving slabs. In production, this is a table with a vibrating surface, which is designed to remove air (voids) from the concrete mixture. Making paving slabs at home does not preclude its use.

It’s difficult to do without a vibrating table, but it can be successfully replaced by tapping the mold or shaking (impacting) the mold on the flat surface.

The simplest solution is to use an old washing machine switched on to spin mode. This homemade vibrating table for paving slabs allows you to get a perfectly compacted (compacted) mixture for making road slabs.

3. Rack for drying paving slabs (dryer). Any place where the tiles will dry in the mold for 2-3 days, without the mold for another week, and then finally dry for another month.

4. Bucket, basin or suitable container. Serves to heat the mold with tiles and facilitate the process of removing the tiles from the mold.

5. Molds for making paving slabs. There are no problems with the forms at all due to their diversity (can be ordered in the online store). To speed up the process, it is better to immediately purchase a dozen forms.

Types of tile molds

Silicone molds for paving slabs Silicone molds for paving slabs. Used for the manufacture of tiles of complex shapes with different structural surface. The elasticity of the material (silicone) is both a plus and a minus of the form. The advantage is that they reproduce the drawing in the smallest detail. Disadvantage - the form expands (swells) from the concrete and changes its shape, which affects the geometry of the product (deformation). One form is designed (withstands) 50 cycles.

Used for making simple pattern. Advantages of a plastic mold: flexibility, strength and durability. The estimated service life of the molds is 800 cycles.

Polyurethane holds its shape better than silicone, but is more expensive. The polyurethane mold is enough for 100 cycles.

How to make molds for paving slabs with your own hands

Several options for making molds from improvised materials:

• Wooden forms can be knocked together from scraps of plywood or boards, and fastened together with metal corners.

Homemade wooden mold for paving slabs It will not be possible to make a mold from wood with complex geometry. The wooden mold can be made in the form of a triangle, square, rhombus, rectangle or hexagon.

Note. When planning to make a mold for paving slabs, keep in mind that its internal dimensions are taken into account.

• Plastic molds can be made from strips cut from utility boxes. It is difficult, but quite possible, to make a complex polygonal shape, the diagram of which is given below.

Note. In such homemade form The tiles are cast directly at the installation site.

• Forms from food containers (bowls, trays, plastic containers)

• Make it yourself from polymer (but this is already from the category of private entrepreneurship, all that remains is to register an individual entrepreneur and open your own business - a business for the production of paving slabs on an industrial scale).

Options for molds for paving slabs Tip. Choosing curly shape, pay attention to the presence of halves and parts (component elements, fragments) in order to avoid unnecessary cutting of the tiles when laying.

When studying the question of how to make paving slabs with your own hands, it is important to pay attention to how to choose the right proportions and how to mix the solution for laying.

Mortar for paving slabs - proportions, composition, preparation

To begin with, we will provide ready-made recipe mortar for paving slabs with a given thickness of 60 mm. And then we’ll tell you how to mix the components correctly.

The composition of the solution for paving slabs is given in the table

From 1 cubic meter solution can be made 16.5 sq. m. paving slabs, with a thickness of 60 mm.

To cook good solution for paving slabs, you need to mix the components in a concrete mixer in a certain sequence, with a certain mixing mode.

1. Preparation of the solution

The plasticizer is mixed with a small amount of water and poured into a concrete mixer. For mixing it is used only warm water, because Additives do not dissolve in cold conditions. When stirring, you need to ensure that the plasticizer dissolves completely.

The dye is also mixed with hot (approximately 80 °C) water in a ratio of 1:3. It is necessary to ensure that the coloring solution is homogeneous. The presence of lumps will result in the appearance of craters on the front surface of the tile.

Next, filler (crushed stone and sand) is added one by one, then cement. Periodically, water is added to the cement-sand mixture for more convenient mixing. The bulk of the water is supplied at the end of the batch.

Optimal mode(time) stirring cement mortar

The mixture for paving slabs is ready when it adheres to the trowel in a dense mass without spreading. When pouring, the solution should easily fill the mold.

2. Preparing the mold

The surface of the mold is lubricated with the selected lubricant. During the process, you need to ensure that no stains from the lubricant form on the surface. The form should be slightly oily for better glide of the product over the surface.

Notes. Excessive lubrication causes depressions in the tiles. If it is insufficient, removal is difficult.

3. Manufacturing technology of paving slabs (molding)

At this stage, the solution is poured into molds. Moreover, if two-color tiles are made, then the form is filled with gray concrete by 75%, and then filled with colored concrete. The break between fillings should not exceed 20 minutes. Otherwise, the layers of the solution will not adhere firmly to each other.

Filled forms need to be shaken and placed on a vibrating table. The duration of the mold's stay on the vibrating table is 5 minutes. An indicator of readiness is the appearance of white foam - this means that all air bubbles have been knocked out of the solution. Excessive vibration treatment (shaking the mold) can lead to stratification of the solution. The signal to stop vibrations is the settling of white foam.

Advice. When making two-color paving slabs, vibration must be carried out after pouring each layer. The second vibration lasts 2-3 minutes, and foam may not appear.

4. Drying paving slabs at home

Forms filled with solution are placed on racks for subsequent drying, which takes 2-3 days. The drying area must be protected from direct sun rays, well ventilated. To reduce the rate of moisture evaporation from the solution, it is better to cover the mold plastic film.

5. Unmolding paving slabs (removal from mold)

To make the extraction process easier, you can lower the filled form for 5 seconds. into hot (about 60 °C) water. The heat expands the mold and the tiles are removed without defects or problems.

The product should be knocked out on a soft base, for example, spread out an old blanket.

Tile removed from mold Please note that the removed tile holds its shape well, but the mortar has not yet hardened completely, so the composition will crumble and may crack or break.

Drying paving slabs on racks The removed tiles are stored on the same drying racks for another week. Then it can be put on a pallet and finally dried for another month. During this period, the tile will gain the required strength.

How much does it cost to make paving slabs at home?

This is not an idle interest, but a rational approach that requires calculations, drawing up estimates to determine the budget and profitability.

Calculation of the cost of manufacturing paving slabs

The table shows approximate prices per unit of production. The total amount depends on the expense.

The price of ready-made paving slabs of a simple configuration starts from 200 rubles. per sq.m., textured from 450 rub. Multiply by the required quadrature (area) and add delivery. Compare your results. On average, savings range from 10% (for local tiles) to 25% (for branded tiles). At the same time, it should be understood that each manufacturer, in a competitive environment, strives to reduce the cost of its products as much as possible. As a rule, this affects quality, which cannot always be determined immediately, but only after some time.

Defects in paving slabs

In favor of making paving slabs yourself, the following can be noted:

• confidence in the quality of the product;

• the ability to make tiles in between other tasks;

• fascination of the process;

• a beautiful result and pride in one’s own success.
