PVA glue can be diluted with water. How to dilute PVA glue with water

PVA glue is often used for gluing objects made of paper, cardboard, leather, wood, and fabric. Its price is low, and the level of strength and adhesive bonding is good. The adhesive is resistant to high humidity indoors, and also has high frost resistance. It is non-toxic and fireproof. If you apply glue thin layer, then it is practically invisible.

But despite all the advantages, like all other liquid glues, PVA glue can thicken. In this situation, do not rush to throw away the glue and run to the store for a new one. Everything can still be saved.

How to dissolve PVA glue

The question that comes up most often on the Internet is the question of how to dilute PVA glue and whether it can be diluted with water. Yes, you can. Need to use warm water(but not hot).

Various solvents may have negative influence on the structure of the glue and its technical characteristics. You need to mix the glue with water with high intensity. Pour in water in small portions, stirring constantly. Water should be no more than 5-10% of the original volume of glue. If the PVA glue has become very thick, you need to know how to dilute it. The crust that appears on its surface should be removed. There is no point in removing jelly-like lumps of glue; they will dissolve on their own.

Such a problem as how to dilute PVA glue if it has thickened, has only one adequate solution - H2O (water). Do not try to dilute the glue with acetone or alcohol - it will be cheaper to buy new jar PVA, especially since it is very cheap.

If you suddenly get the idea to dilute the glue with acetone, get rid of it as soon as possible. Acetone, if there is too much of it in the glue, will literally “eat” plastic or plastic products, if you are going to use it for them.

Hot water is still the most the best solvent for PVA glue.

If the question is about how to dilute PVA glue, if it is very thick, then water is unlikely to be effective here. In any case, you can try.

There is no solution to the question “how to dilute PVA glue” only if the glue has completely dried - then there is definitely only one way left for it. In the trash bin.

Who doesn’t know about PVA glue, which is actively used for gluing products from various kinds materials: wood, ceramics, chipboard, linoleum, paper, glass, fabric and leather bases. The popularity of the glue is determined by the high-quality adhesion of the material and the surface being glued, affordable cost, increased resistance to moisture, but, at the same time, good solubility in water, which in itself answers the question, how to dilute PVA glue? The purpose of the glue is determined depending on its type.

PVA glue is the most popular substance in the world. It is universal and will be useful both when studying at school and when carrying out repairs in a house or apartment.

What kind of product is this - PVA glue?

The history of the composition goes back more than a century, and it was invented back in 1912 of the last century in Germany. A couple of years later, the glue entered the sales market and began to be produced commercially. In 2018, glue production capacity exceeded one million tons of the substance.

What does the substance consist of?

PVA stands for Polyvinyl Acetate Adhesive, component composition which consists of:

a special synthetic fiber based on polyvinyl alcohol - vinalon, which accounts for about 95% of the product;
various additives that increase plasticity, stability, and adhesion strength.

Main types of PVA glue

The main types of PVA glue compositions, divided into types according to purpose, include:

stationery - for gluing paper and cardboard bases;
wallpaper or household - for gluing paper materials to wooden and cemented surfaces;
construction - for fiberglass, paper and vinyl compounds. Serves as an additive for primer compositions, which helps improve the technological properties and adhesion of subsequently applied materials: putty, plaster, dry mortar;
super M - indispensable for gluing products made from vapor-proof materials, ceramic and porcelain products, fabrics, glass, leather. In addition, it is used when installing a variety of floor coverings;
Extra - used for gluing wood, plywood, construction mesh, wallpaper (cork, vinyl, paper, fiberglass), serpyanka. Used as an additive to improve strength;
Universal - useful for gluing paper and laminated paper decorative plastic to wood, glass and metal surfaces.

Is it possible to dilute the glue and with what?

So, we come to a question that interests many: how to dilute PVA glue? Let us hasten to answer - yes, it is possible. You just have to do it right. How to cope with such a seemingly simple task and not spoil the glue, read on.

In order to cope with the task, try to adhere to some recommendations and dilute the glue only warm water, various types of solvents have a negative effect on technical properties and the structure of the composition, destroying it. In this case, it is necessary to mix the glue as intensively as possible.

How to dilute a heavily thickened composition

Let's figure out whether it is possible to dilute the PVA glue. When the glue dries and becomes very thick, a crust or small dry particles resembling flakes form on its surface. These impurities that the solution may contain should be removed before applying the composition to the surface.

Clumps of jelly consistency can be left as they dissolve when stirred.

How to dilute the dry mixture

You already know how and with what to dilute PVA glue in its usual form, but sometimes you have to work with a dry mixture. Such substances are diluted according to the proportion or ratio indicated on the packaging. The manufacturer recommends that you adhere to these recommendations, otherwise the glue will lose its technical properties and will be useless for gluing.

Exception to the Rule

If 90% of types of PVA glue can be diluted with water, then 10% falls on special category adhesive compositions, present on the market and not amenable to dilution with water. They are usually presented in ready-made form: in a diluted state and in appropriate containers, since they are characterized by an unpleasant chemical odor, and the substance dries out quickly in open cans. To prevent the glue from hardening, try to buy containers that are large enough to apply the glue at one time. This will save both glue and money.

There are exceptions when such glue is diluted, but only with the use of a special synthetic solvent.

How to properly apply diluted glue to a surface

So, having figured out how to dilute thick PVA glue, working with it does not involve any difficulties. It's quite simple. The presence of instructions will simplify the task, since the insert contains brief information about what this or that type of product is used for gluing and how to use it correctly. Since the application of wood glue and paper glue is different in some way, some people encounter problems when gluing wooden surfaces. To prevent unpleasant moments from happening to you, remember a simple rule: apply glue to the side of the product that absorbs the composition more slowly, that is, with a less porous structure.

Is it possible to dilute PVA glue with water? We figured it out. Remember that when working with PVA glue, regardless of the type, follow some rules:

After studying the information provided in the article, you received an answer to the frequently asked question: “how to dilute PVA glue?” Taking into account the recommendations given, the use of glue will be a rational solution for you if you need to connect any parts together.

PVA glue is one of the most popular in our country. He is appreciated not only for affordable price, but also for excellent adhesive properties, which are indispensable in everyday life and creativity.

It is difficult to find at least one adult who has never encountered PVA. It has become widespread both in industry and in everyday life.

PVA glue includes a polyvinyl acetate dispersion, which hardens in just a day, is easy to apply, as well as a filler, which is water.

In order to remove the composition, no special means are required. Enough Dilute PVA glue with water. Water is used to soften the stagnant product, which can be used again for its intended purpose.

How to dilute PVA glue with water

It is possible to dilute PVA with water, but it is worth keeping in mind that the more water, the less strong the adhesive joint will be, and its elasticity will also decrease after hardening. Adding water also reduces the water resistance of the adhesive.

Household and office PVA glue can be diluted. You shouldn't do this with universal glue and PVA-super.

Mixing order:

Prepare a container, add one part glue and two parts water. Carry out work only in a warm room.
Mix the mixture thoroughly with a spatula or stick. Stir until the water is completely dissolved.
You should end up with a runny mixture. white. It will be easily applied to the surface and will allow, for example, to prepare walls for painting.

Why is PVA afraid of water?

The main reason is that the glue loses its properties; it gets wet and dissolves. The more water there is, the worse the glue will connect the parts.

In some cases, if the composition has thickened, water is added deliberately to dilute it. But if you violate the proportion of 2 parts glue to 1 part water, then you risk getting a completely useless liquid.

You can also make PVA glue from water using other available materials, for example, using a simple and inexpensive ingredient that every housewife has - ordinary starch.

To do this, you also need to take potato flour or wheat flour, pour it cold water.
Next, the contents are mixed and the water begins to boil.
A mixture of water and starch is poured into boiling water.
The mixture is stirred for ten minutes, and when it is half ready, put on the stove and cook until the mixture reaches the consistency of jelly.
The result will be a translucent glue, an analogue of PVA with good adhesive properties. This option is easier to make at home, but is slightly less effective than flour-based glue.

The PVA glue has become very thick, can it be thinned with water?

What types of glue can be diluted with water?

PVA can be diluted with water, you just need to mix it quite intensively when mixing it with water. You can also dilute almost everything with water. wallpaper adhesives, but you need to strictly follow the instructions on the package to achieve the optimal consistency.

Definitely, PVA glue is diluted only with water; no solvents can be used, they will destroy the PVA structure and it will lose or reduce its properties. If the glue has thickened greatly, a crust has appeared, and possibly dry flakes, then the glue must be separated from these dry impurities, Do not separate clots that resemble jelly; they will dissolve! Next, add warm water to the PVA and stir well, adding water until the desired state, then strain and you can use PVA.

There are adhesives that are sold in dry form, for example CMC, but they are diluted according to the instructions with water only before use and are used in very short term, since when stored in a diluted state for more than 12 hours, they completely lose their gluing properties and are stored exclusively in a dry state.

By the way, with a huge number of brands and names, it is mainly CMC (carboxymethylcellulose), a product produced during wood processing, that is used in wallpaper glue.

As for glue that cannot be diluted with water, they are mainly sold in a ready-made state, in tightly closed containers, since they have strong smell and dry very quickly, are flammable and can be diluted with personal solvents for each specified on the container!

Yes, PVA glue can be diluted with water! The main thing is to mix it well immediately after adding water, it is also necessary to mix it every time before applying it so that the glue does not turn out to be uneven.

Do not add too much water, because glue with too much water will cease to perform its functions.

Also remember that diluted PVA glue may not glue ceramics and other things; it is more suitable for paper. For good gluing of other items, it is better to try to mix your thick glue and use it.

If you mean PVA glue, then of course you can. True, you should carefully add water a little at a time and stir thoroughly until the solution reaches the consistency you need. But you need to remember that the more the glue is diluted with water, the more it loses its properties. By the way, it is not recommended to store glue diluted with water.

You can add just a little water to the PVA, but if we are talking about a large volume of glue, then it is better to immediately mix it thoroughly with a drill with an attachment in the form of a spatula or other shape. This way you will get a homogeneous mass of the required consistency.

For any type of wall finishing, be it putty, plaster, painting, or before wallpapering, you must first prepare the surface. Priming is one of the main stages that must be completed first, because with the help of soil you can achieve better adhesion finishing material with the surface. However, presented on construction market materials are quite expensive. But there is a great one economical solution– PVA primer. It is not difficult to make it yourself, and this solution is suitable for both wooden and concrete and brick surfaces.

PVA glue is a water emulsion of polyvinyl acetate. This chemical substance solid granular substance without distinct color and odor. The material is used in construction, furniture production, carpentry. It is actively used by schoolchildren, students, and needlewomen. Polyvinyl acetate glue connects various materials: paper, cardboard, wood, rubber, ceramics.

To obtain a primer, PVA glue is diluted with water. On the surface, such a mixture forms a thin transparent film, which has many of the properties of specialized primers.

PVA based primer can be used as an intermediate layer between the surface and finishing coating, promoting good adhesion of materials and reducing the risk of their peeling from the wall as a result of moisture getting on it. In addition, the use of such a primer will reduce the consumption of putty or paint used.

Advantages and Disadvantages

A primer made from PVA glue has its advantages and disadvantages. The undoubted advantages are:

Increased adhesion. An additional layer is created to securely fix the finish to the surface.
Reduced moisture absorption. The soil penetrates the surface structure, filling its pores and preventing moisture from entering them.
Creation of a protective layer. A thin polymer barrier helps combat aggressive environmental influences.
Decrease in quantity consumables (plaster, paint, glue).

In addition, a primer made from PVA ensures even application of paint and facilitates the process of wallpapering. Of course, all this is sufficiently ensured by commercial primer, which is available in a wide range. But often its high price forces us to look for more profitable solutions. Therefore, using PVA instead of a primer is a completely justified option.

Despite all the advantages, this composition still has disadvantages. These include:

Ineffective– insufficient penetration into the material.
Lack of antiseptic properties– the primer will not be able to resist the growth of microorganisms (mold, fungus).
Education yellow spots and divorces– spoils appearance finishing.
The material loses its properties in damp areas– not used to cover walls, ceilings in bathhouses, swimming pools.

Knowing some subtleties, you can turn disadvantages into advantages and improve properties aqueous solution PVA for priming walls. So, for example, you can increase the ability to resist mold by adding a little whiteness to the composition in the proportion: 50 g of disinfectant per liter of ready solution. Add 3% of its volume to PVA soil liquid glass, it is possible to increase the permeability into the processed material, especially into wooden substrates.

If financial resources are limited, it is better to use adhesive primer in utility or non-residential premises. In the living room and bedroom, combination with expensive wallpaper will not suit such a primer, because there is a possibility of yellowing, which will significantly change the interior for the worse.

Prepare the primer yourself

How to make a mixture that has the properties of a primer? You need to take the following components:

PVA glue – 1 part;
water – 2 parts;
cement - the amount is determined by the density.

The preparation technology does not cause any difficulties: the glue is diluted with water, mixed, added required quantity cement. The finished solution should resemble liquid sour cream and fit well on the surface.

Important! Before you make a PVA primer with your own hands, decide on its quantity. The mixture should not be prepared for future use, since unspent excess will eventually lose its binding properties.

Diluted primer is an excellent, economical means of preceding the treatment of walls with wallpaper glue, but is not sufficient for a reliable finish. Is it possible to improve the quality of the primer composition? Repair experts advise adding crushed chalk and liquid resin to the mixture with PVA glue. Their mass should not exceed 5% of the total volume of the composition.

Important cooking conditions:

Work on creating a primer should be carried out in a warm room, away from drafts and sources of fire.
Use convenient containers: a large bucket, a basin, a canister with a wide neck.
Water is added to the glue gradually, the classic ratio is 2:1.
Constant stirring of the composition will prevent the formation of a surface water layer. To facilitate labor and obtain the greatest homogeneity, you can use a construction mixer.

Priming walls with glue is different in that it forms a film on the treated surface without filling small cracks and gaps. But, given the relatively low cost of the components used, the result is an excellent building material that can be quickly made at home.

The finishing goals should be clearly defined. A universal primer that does not require increased water resistance is suitable for wallpaper. Elite finishing decorative plaster requires a more expensive adhesion coating.

Correct application technique

Knowing the theoretical techniques of how to dilute PVA for primer, it is necessary to achieve the correct consistency. To begin with, you should try applying the mixture on a small area of the wall intended for wallpaper. The liquid mass is applied to the surface with a paint roller or wide brush, leaving a white mark.

After drying, the resulting film should not be noticeable. This emphasizes the correctness of the chosen proportions. You should add a little water if the opposite occurs.

Work on applying the primer is carried out in several stages:

1. First of all, the corners and hard to reach places. Next, the primer is applied to the main areas using a short-haired roller.

2. The roller must be dipped in the resulting solution and lightly squeezed against the ribbed part of the container. Convenient device is a special bath with an inclined ribbed surface. By rolling a roller over it, you can squeeze out excess liquid. As a result, wet spots and smudges do not form.

3. For best result You can apply another coat of primer. This ensures reliable adhesion of small dust particles and makes it possible to further apply the putty evenly (it will peel off less).

4. You must wait until the surface is completely dry. The wall should take on a whitish color.

The resulting two-layer polymer coating reliably protects the surface, increases adhesion, and allows you to proceed to applying decorative finishing.

Save on repairs

If not PVA, then what?

You can also use regular wallpaper glue as a primer. It has distinctive features:

does not form yellowness;
has better absorption;
does not form a film;
inexpensive;
easy and quick to apply.

Another way to make a primer and save money is to use concentrates. The instructions for them indicate how to dilute such a composition. Sometimes it can be increased 10 times.

Before painting acrylic paints Using a self-primer is not advisable. It is enough to mix the coating composition with water in a 1:1 ratio. The paint itself will act as a primer. It should be applied evenly with a roller. Savings are achieved by reducing the applied layers.

Brush, roller or spray gun?

The selection of tools also plays a big role. Applying primer using a spray gun - fast work from the technical side, but in terms of aesthetics - this is not acceptable option, since there are many traces and smudges that are difficult to wash off.

Using a brush is unprofitable from an economic point of view - it increases the consumption of material. Used for working in corners. On large areas It is better to use a roller with short or medium pile. But on walls that have unevenness in the form of protrusions and dimples, you cannot do without a brush.

PVA primer does not have the properties it has special compounds for repair. Despite this, it is an indispensable tool for preparatory work, allows you to significantly save material resources. Proper preparation, compliance technological process turns homemade composition into high-quality primer material.

PVA glue is in demand in everyday life. This is due to its availability, gluing results and ease of application. It consists of polyvinyl acetate dispersion and water. The applied layer dries completely within 24 hours. They connect paper, cardboard, fabric and wooden parts. It is added to gypsum mixtures and used to prepare walls for wallpapering. It is suitable for products susceptible to high air humidity and is resistant to frost.

The product contains no toxins or flammable components. It can be used in indoors no risk fire danger. When applying a thin layer of glue, it becomes almost invisible on surfaces.

If the mixture is too thick, if the glue has been stored for a long time after opening, it can be diluted with liquid. This will allow you to save money by doing necessary work, without visiting a stationery store. The situation can be corrected when it is thick. The dried glue can only be thrown away.

Depending on the purpose, PVA can be:

household (wallpaper), connects paper surfaces with cement and wood;

stationery, which helps to fasten paper and cardboard;

construction (additive to primer mixtures), used when working with fiberglass, vinyl and paper;

extra, securely adhesive different types wallpaper, plywood and wood;

universal, used in creativity for connecting paper parts with wooden, glass and metal parts;

super M, which glues ceramics, porcelain, knitwear and is used for styling flooring(indispensable when working with vapor-tight surfaces).

Distinctive characteristics are due to the composition of the glue. It is not always possible to dilute a thickened mixture. You can try diluting the last two types of glue with acetic acid or organic solvent, for example, acetone.

Can PVA be diluted with water?

The idea of diluting thickened glue with water is explained by the presence of the liquid itself in its composition.

This is one of the working ways to save glue and solve a problem, for example, with a children's applique, without going to the office supply store. When diluting PVA with water, you need to use a warm liquid (room temperature). If it is hot or, conversely, cold, then the composition itself will lose its technical characteristics and the finished seam will not be so reliable.

In terms of the ratio of components, it is necessary to adhere to the proportion of 1:10. The amount of glue should exceed the added liquid ten times. If the proportions are increased, then ready mix will partially lose the effectiveness of gluing parts; for example, it may not cope with connecting wooden bases.

If it has thickened after long-term storage, then first you need to remove the top crust. Glue lumps of jelly-like consistency should dissolve when thoroughly mixed with water. There is no need to remove them.

Do not use acetone or alcohol to dissolve office glue. This then increases the risk of corrosion of the surfaces being joined, such as plastic.

The thickened mixture can be diluted with water (try) or replaced with a new one. The only exception is a completely dried product, which can only be thrown away.

If the PVA glue is household or office, then dilution with water is still possible. PVA-super and universal composition You can only throw it away or replace it.

To thoroughly mix the composition with warm water, you need:

prepare the container;

pour out the glue and then add water;

mix the consistency until a homogeneous white mass is obtained;

let it sit.

If the prepared solution is used immediately, the product itself may be damaged. After mixing, leave the container alone for at least half an hour. If glue will be used as a primer for walls to increase adhesive properties, then the amount of water should be twice as much as glue. You should get a liquid white mixture. This option is used before painting surfaces. In other cases, the volume of water should be less than the adhesive mixture. Even a ratio of 1 to 2 (water to glue) can lead to useless results.

As an alternative, you can try making your own adhesive mass from starch or wheat flour. You need to fill the dry mixture with cold water. In a separate container, you need to boil water and gradually, while stirring, pour in the cold mixture with starch or flour. You need to stir everything together continuously for at least another 10 minutes. You should get a jelly consistency. With flour, the composition will be more durable and effective compared to starch.

How to dilute the dry mixture

Wallpaper or wallpaper is sold as a dry powder. household option. To dilute PVA glue of this type, you need to follow the proportions (1 liter of warm water per 100 g of dry mixture). You need to mix thoroughly until the consistency of thick sour cream is formed. The brush or roller left in the container must remain in an upright position. If the mixture is to be used as a primer, more water is needed. If ready solution If it is not thick enough, it can be left for a day, allowing the water to partially evaporate.

PVA glue is often used for gluing objects made of paper, cardboard, leather, wood, and fabric. Its price is low, and the level of strength and adhesive bonding is good. The glue is resistant to high indoor humidity and also has high frost resistance. It is non-toxic and fireproof. If you apply the glue in a thin layer, it is almost invisible.

How to dissolve PVA glue

The question that comes up most often on the Internet is the question of how to dilute PVA glue and whether it can be diluted with water. Yes, you can. You need to use warm water (but not hot).

Various solvents can have a negative impact on the structure of the adhesive and its technical performance. You need to mix the glue with water with high intensity. Pour in water in small portions, stirring constantly. Water should be no more than 5-10% of the original volume of glue. If the PVA glue has become very thick, you need to know how to dilute it. The crust that appears on its surface should be removed. There is no point in removing jelly-like lumps of glue; they will dissolve on their own.

Hot water is still the best solvent for PVA glue.

If the question is about how to dilute PVA glue, if it is very thick, then water is unlikely to be effective here. In any case, you can try.

There is no solution to the question “how to dilute PVA glue” only if the glue has completely dried - then there is definitely only one way left for it. In the trash bin.

Moment glue is universal. People often resort to its help in everyday life, but, unfortunately, they sometimes forget about neatness. It is better to engage in gluing objects in old clothes and rubber gloves. But if, nevertheless, the glue ends up where it was not intended (on good clothes, the hands of a master, or on some objects), it needs to be cleaned.

If possible, remove the glue immediately before it dries. A “fresh” stain is much easier to dissolve than an old one. If you don’t have a single recommended product on hand, the contaminated area can be moistened with water. This will increase the drying time of the product, and you will have time to find suitable option to remove it.

Anticlean

This special remedy sold in almost all construction stores. Outwardly, it looks like a tube of glue, but it acts diametrically opposite. Please read the instructions carefully before purchasing. The fact is that anti-glue is an aggressive chemical substance that is not suitable for all surfaces. Although it can be used to quickly and effectively remove stains from the floor, furniture, etc. It must be remembered that anti-glue is a toxic substance, so you need to be careful when using it and, of course, keep it away from children.

Acetone and nail polish remover

It is better to work with acetone outdoors. A cotton swab or rag is moistened in the product. First, you need to check the effect of the liquid on an inconspicuous area of the surface, since there is a possibility of loss of color of the material.

This method is suitable for removing adhesive from many coatings., including metal and wood. However, be careful with plastic and textiles. Acetone is harmful to delicate fabrics (wool, velvet, silk), as well as to fabrics that contain acetate. After the glue is removed, the item must be washed or washed with soapy water.

Nail polish remover is much less harsh than pure acetone. However, it is also best to first perform an interaction test with the surface being cleaned. The liquid is applied to the stain for 15-20 minutes, then the glue is removed with the hard side of a dishwashing sponge. After this, the item is washed (or washed) in the usual way.

Gasoline and white spirit

These liquids are also aggressive, so they are best used on fresh air or in a well-ventilated area. Operating principle in in this case similar to working with acetone. First, check the interaction with the surface in an inconspicuous area. Then carefully apply the product using a cotton swab, remove any remaining glue and put the item in the wash (or wash it with soapy water). White spirit solvent is recommended as a suitable solution for removing adhesive from iron and plastic.

Dimexide

This one is synthetic medicinal product sold in pharmacies. It dissolves any remaining adhesive on different surfaces, both hard and textile. This is what they recommend craftsmen for removing traces of glue from monitors of laptops, tablets, phones. The work follows the same scheme: apply, wait, wipe off, remove the remaining product with a napkin.

Vinegar and citric acid

You can also prepare solutions for removing glue from vinegar or citric acid. The resulting compositions will be less effective than chemicals, but more gentle.

Recipe with citric acid: 25 g of acid is dissolved in a liter of water. Recipe with vinegar: dilute one part vinegar with two parts water. You need to moisten a cloth in one of the solutions, and then use it to carefully try to wipe off the glue.

Soap solution

This method is suitable for removing dirt from fabric. You need to make a “strong” warm soapy solution and soak the fabric in it for 20 minutes. Then you need to wash the item.

In this case, a solution of any detergent can help. Of course, it will not immediately dissolve all the glue, but it will be able to soften it, which will make removal easier. And while you are busy preparing the soap solution, your hands will also be cleaned if they are also dirty with glue.

Margarine, vegetable oil

Glue residues can also be easily removed from the skin of your hands using oil. They need to smear the contaminated area, wait 15 minutes, and then rinse the skin with warm water. You can also try to remove glue stains from plastic and wood with oil, but this method is only suitable for treated or polished wooden surfaces. This is worth taking into account, otherwise oil stains will be added to the glue stains.

The PVA glue has become very thick, can it be thinned with water?

What types of glue can be diluted with water?

PVA can be diluted with water, you just need to mix it quite intensively when mixing it with water. You can also dilute almost all wallpaper adhesives with water, but you must strictly follow the instructions on the package to achieve the optimal consistency.

Definitely, PVA glue is diluted only with water; no solvents can be used, they will destroy the PVA structure and it will lose or reduce its properties. If the glue has thickened greatly, a crust has appeared, and possibly dry flakes, then the glue must be separated from these dry impurities, Do not separate clots that resemble jelly; they will dissolve! Next, add warm water to the PVA and stir well, adding water to the desired state, then strain and you can use the PVA.

There are adhesives that are sold dry, for example CMC, but they are diluted according to the instructions with water only before use and are used in a very short time, since if they are stored in a diluted state for more than 12 hours, they completely lose their adhesive properties and are stored exclusively in dry conditions. condition.

By the way, with a huge number of brands and names, it is mainly CMC (carboxymethylcellulose), a product produced during wood processing, that is used in wallpaper glue.

As for glue that cannot be diluted with water, they are mainly sold in a ready-made state, in a tightly closed container, since they have a strong odor and dry very quickly, are flammable and are diluted with personal solvents for each indicated on the container!

Do not add too much water, because glue with too much water will cease to perform its functions.

Also remember that diluted PVA glue may not glue ceramics and other things; it is more suitable for paper. For good gluing of other items, it is better to try to mix your thick glue and use it.
