Wood fiber plastic (fiberboard, hardboard) - durable and durable material, used not only in construction and repair work, but even for decorative purposes. At the same time, the dry utility of fiberboard requires that the final surface be decorated in some way.

This can be done by pasting Fiberboard wallpaper or with an opaque film, or you can paint the front surface of the plastic. Facial because with opposite side it will take much longer to tinker - it is smooth, and therefore practically does not hold any paint.

Features of the color of the material

Fiberboard production technology determines its porous structure. According to this indicator, hardboard is much superior to wood. Therefore, you will have to come to terms with the fact that the consumption of any paint and varnish composition, which has an intention to paint fiberboard, will be much higher.

For example, if the manufacturer indicates its approximate consumption per 1 m2 of the painted surface on a can with paint, then it is worth remembering that these figures are given for low-porous substances. For fiberboard, the specified rate will have to be increased by 2.5-3 times.

Painting technology also largely depends on what we are going to paint. Some formulations will be optimal for the floor, and others for walls or pieces of furniture.

Paint consumption can be somewhat reduced by pretreating the painted surface with coarse-grained sandpaper... The dust from the abraded fibers gets clogged into the pores, and thus does not allow the paint to penetrate too deeply into the structure of the hardboard.

Preparatory work

The preparation is as follows:

1. Surface grinding for painting. In addition to eliminating pores, grinding will make the original roughness of the material more uniform, which will not only facilitate the coloring process itself, but also increase the visual perception of the finished result.
2. Putty joints. Performed if it is necessary to paint several connected sheets of fiberboard. Not any putty is suitable, but only one that is characterized by increased plasticity, in particular, acrylic. It will help to tightly fix the contact points of adjacent sheets and thereby facilitate their subsequent staining. Acrylic or silicone based sealants can also be used.
3. Degrease the surface with any organic solvent... The operation is performed so that traces of grinding, as well as excessive oiliness of the surface, do not impair the quality of its painting.
4. Primer. Provides a reduction in the consumption of the base paint; at the same time, those pores that could not be eliminated as a result of grinding are closed at the same time. The primer should be warmed up to 40-60 ° C before use. The viscosity of the primer (common linseed oil is most often used, although alkyd primers are also suitable), this decreases, and its fluidity increases. The primer is applied in one layer.

As a working tool for fiberboard painting hard brushes and rollers on a natural (not foam rubber) basis are suitable. The rest of the options are unsuitable, since they will not be able to hide the fibrillation of the original surface, and traces of paint layers will be very noticeable.

Good results are obtained by painting fiberboard with a spray gun or a spray gun, however, the costs with this method of painting will increase. Mechanized painting is justified only with significant processing areas.

The sequence of staining hardboard

The choice of paint for painting fiberboard does not matter. Rather, it is important where the painted fiberboard will be located. If on the floor, then paint with increased wear resistance is suitable - alkyd, acrylic, oil (the latter, however, dries longer). It is perfectly acceptable to use water-based paint for walls.

Sometimes, after staining, the finished surface is varnished for decorative purposes. This does not give a special effect for fiberboard, but if there is a desire to give the surface a more presentable appearance, as well as to increase water resistance (this is advisable for furniture parts), then the plastic can be coated with transparent varnish.

When using parquet varnish, it is possible to achieve greater resistance of the fiberboard from abrupt changes relative humidity indoor air.

Separate moments

If the fiberboard is located on the floor, then the finished surface should be varnished not in one, but in two layers.

Sometimes used purely decorative painting plastic. Then, on the contrary, they try to emphasize its fibrous primary texture. To do this, staining is done with bituminous varnish using a small brush.

To achieve the effect of smoothness of the fiberboard surface, it is painted in light or even white colors, and to achieve a matte surface, paints on a water-dispersion basis are used.

Most people believe that the process of painting a fibreboard is simple. But most often this opinion remains so until it was necessary to paint the fiberboard in practice - the number of problems faced by newcomers in this matter can hardly be overestimated. Let's see how and with what to paint the fiberboard (fiberboard).

Fiberboard is made by pressing the waste left after woodworking. When exposed high pressure and high temperatures a smooth and lightweight material is formed. Due to their advantages, the slabs can be used for cladding walls, floors, often you can see fiberboard on the ceiling. Also, the material is widely used for the production of cabinet furniture.

Among the main advantages are:

• Affordable cost. The slab is made from various waste woodworking industries. It also contains a sealing resin and antiseptic additives. The price for these materials is much lower than for other analogues.
• Strength. On modern construction market Fiberboard boards of various strengths are offered - the strongest of them is marked "ST".
• Resistant to moisture. If the fiberboard is properly processed and then painted, the material will be well protected from moisture.
• High durability. At the production stage fiberboard sheets covered with special impregnations that protect the material from fungal growths or insects. As a result, the slabs can keep their original appearance for a long time.

Like any other material, fiberboards have disadvantages, but there are only two of them:

• impossibility of using in various load-bearing structures;
• decorative processing is possible on one side only.

Slabs are great for arranging rough or finishing floors, but their surface should be carefully treated beforehand.

Dyeing technology

Fiberboard painting technology is no different from painting any other materials. The process is carried out in several stages:

• collection of tools;
• surface preparation for painting;
• choice of paint;
• directly painting;
• applying a protective coating.

Required tools

To paint a fiberboard floor, you need to prepare:

• fur roller (foam rubber is not suitable for these purposes);
• paint brush;
• paint tray;
• rag;
• vacuum cleaner.

Surface preparation

Must be taken into account important nuance- before performing any work with fiber boards, first the fiberboard is brought to a certain moisture content. Otherwise, over time, the plate will go in a wave, thereby ruining the floor or wall. Moistening fiberboard is simple: reverse side leaf wet warm water, and then fold the sheets in pairs. The plates must be left to dry for a day.

Often, floors are trimmed from fiberboard. In order for a fiberboard floor to boast the same lifespan as a wooden base, it is important to properly process it, including painting. Hardboard floor is very porous - any paint will be absorbed there in a significant amount than into a concrete or wooden floor.

Experts first of all propose to cover the surface with a primer - if this is not done, then a positive result can be achieved, but the paint consumption will be very large.

Paint for fiberboard should be applied only from the glossy side of the sheet - the other is not suitable for this. On the second side, a primer is more appropriate. Due to the peculiarities of manufacturing and structure, the plate is capable of absorbing 4 times more paint, and applying a primer is one of the stages before painting.

Primer materials are now widely represented in the construction market. Fiberboard and hardboard are traditionally processed with linseed oil - this is an affordable and practical tool. But the drying oil should definitely be warmed up to 40 degrees.

Before applying the primer, the slabs are thoroughly cleaned of dust. This can be done both with an ordinary rag and with a vacuum cleaner. The slots on the floor are sealed with tape or reinforced tape. The rest of the surface must be degreased - you can use a solvent or alcohol.

The primer is applied with a roller. Experts recommend applying multiple layers. When the slab is impregnated with linseed oil in three layers, the resistance of the material to moisture is significantly increased. To increase the service life of hardboard, it is necessary to process it after the cutting is done, but before the laying process.

Choice of paint

Fiberboard painting is performed using any coloring enamels however, it is better to choose super-hard types of paints. They are marked - "ST". It is these dyes that will give the floor the maximum resistance to wear and tear. Oil and alkyd paints are used as alternatives.

Water-based paints in this case do not fit - they will not be able to grab onto a fiberboard covering. The plate contains paraffin - it will repel paint.

You can also use decorative varnish instead of paint. There are also some tricks with which you can create unusual color solutions... So, to imitate natural wood a brush can be applied to the surface with liquid bitumen varnish. To create a color with a "plastic surface" effect, glossy compositions are used.

Painting process

For painting work, experts do not recommend using foam sponges or brushes - these tools will not allow you to evenly distribute the dye over the surface. As a result, there will be divorces. Most the best choice- This is a spray gun, but a fur roller will do. For work on small areas, you can apply paint in spray cans - the process will go much faster.

The paint in the jar is thoroughly mixed and, if necessary, diluted with a solvent to the desired consistency.

How to paint fiberboard? First, the first coat of paint is applied. If it seems that somewhere the dye has absorbed poorly or too well, then the defect is not corrected, but they are waiting for complete drying. The next layer is applied to the painted layer after the first is completely dry. It takes about a day to dry completely.

You cannot make a popular mistake and create drafts in the room - the paint will not dry faster than necessary. For the second coat, the paint should be thick. The third layer is applied after the second has dried. Fiber boards after painting do not so much improve aesthetically as increase their strength and other characteristics.

Fiberboard is used for the production of furniture, flooring and wall covering, the construction of partitions and enclosing structures. However, not everyone knows how to paint fiberboard, because this material is different from ordinary plywood or wood. We will tell you how the fiberboard is prepared for painting, and how painting is done.

Fiberboard painting - Fiberboard is sometimes painted - can be done with a brush.

Fiberboard painting

Peculiarities

Before painting the fiberboard, you should find out what kind of material it is and what are its features. As the name suggests, these are wood fiber boards. Fibers are obtained in different ways: by processing wood chips and shavings, plant fires, shredding and other waste from the woodworking industry.

The fibers are collected and pressed by heating with the addition of synthetic resins, as well as hydrophobizing additives (paraffin, rosin) and pectol. Soft varieties of this product can be produced without the addition of resins, due to the lignin released from the cells of wood fibers during pressing. Also, various targeted additives are introduced into the composition of the plates - fire retardants, fungicides and antiseptics.

As a result, sufficiently strong and smooth slabs are obtained, which are characterized by the following qualities:

• High strength... Grades of slabs of the "ST" series can be used for the construction of floors, cars, furniture and other structures that require the ability to withstand high mechanical loads;
• Low price. Due to the fact that the material is produced from waste, its cost is significantly lower than the cost of solid wood or plywood. This explains the popularity of this product in different areas production and construction;
• Moisture resistance... With appropriate processing, fiberboard can withstand high humidity and be used as an enclosing structure in car building, packaging production and other areas of the economy and industry;
• Durability... Factory impregnation with special preparations makes the plates unsuitable for feeding fungi and bacteria, as well as insects and other pests. This allows the material to serve for a long time without significant changes in composition and structure.

Important! Modern material MDF is a type of fiberboard, only for its production fibers of certain types of wood and a special pressing technology are used.

Attention! except general characteristics, we want to highlight one more, at first glance, insignificant feature. This feature lies in the fact that in view of some technological subtleties, the material very actively absorbs and absorbs liquids. This is important from the point of view of painting.

Materials (edit)

Any wood paint is suitable for working with slabs. Since floor coverings are most often made from this material, let's talk about this area of ​​finishing.

Paint for fiberboard floor is selected taking into account the peculiarities of operation, the following options are possible:

• ... Any hard-wearing floor covering based on natural or synthetic linseed oil... Most often, formulations are used based on pentaphthalic varnish modified with alkyd resins (PF-115, PF-226, etc.);
• Wear resistant acrylic paints based on aqueous dispersions. More expensive but also more quality option coatings, especially for living rooms and bedrooms;
• Alkyd-urethane and epoxy compounds. They are distinguished by high strength and reliability, but they are also quite expensive and difficult to apply, since they often consist of two components and require preliminary preparation, taking into account the life time of the diluted material.

Important! Since fiberboard is one of the cheapest options for flooring, it would be logical to assume that its finish should also be in the lower price range. Therefore, in the future, we will consider the treatment of plates with oil enamel paint PF-226.

Execution of works

Now about how to paint a fiberboard floor.

If you intend to do the work yourself, our instructions will help you:

1. Before painting fiberboard floors, the boards should be prepared. To do this, they should be cleaned of dust and dirt, putty the cracks and degrease the surface with technical alcohol. Next, you should heat the drying oil oxol to 50 degrees and apply with a brush in one layer to the entire surface;

1. After complete drying and mix the contents thoroughly. For greater fluidity, you can slightly dilute the composition with white spirit or solvent;

1. Apply with medium bristles. We make the layer thin, shade the coating evenly over the entire floor;

1. We are waiting for the complete drying of the enamel - at least a day. Then we apply the next layer, but with undiluted paint. We finish the work by applying the third layer after the second has completely solidified.

Important! Alkyd enamel is toxic, so work in a well-ventilated area using a respirator and other personal protective equipment.

Output

Fiberboard - widely used construction material, especially for covering floors and walls. Painting the slabs makes them more attractive and extends their service life.

The instructions and video in this article will help you understand the intricacies of painting.

At first glance, the operation of painting a fiberboard (fibreboard) is not difficult at all. However, in order to paint products from this material, one should take into account some of its individual features, which should, first of all, include high porosity. This feature is a consequence of its structure, because this material is produced by pressing wood fibers.

Due to its porosity, this material absorbs significantly more paint than, for example, wood. And the process preparation of fiberboard for painting is significantly different from the process of preparing surfaces made of other materials.

Below we will consider all the difficulties that arise when looking for an answer to the question of how to paint a fiberboard or repaint an old fiberboard. And what tools and materials will be required in order to paint it with your own hands and at home.

The algorithm for applying paints and varnishes to the surface of the material depends little on the material itself and includes the following points:

• Surface preparation;
• Choice of paint;
• Paint application;
• Coating protection.

Surface preparation

The paint is applied to the fibreboard only on one side, because its second side is not very suitable for this.

The process of preparing fiberboard for painting is relatively simple and will not take you much time. It is necessary to remove dirt (dust, etc.) from the surface of the stove. This should be done with a dry cloth or brush. If the stove is heavily soiled, you can use a damp cloth, but first wipe the stove thoroughly so that no dust remains on the surface. After the surface is cleaned, it must be carefully processed with fine-grained sandpaper and degreased, for this purpose it is preferable to use alcohol.

If it is necessary to paint a floor, ceiling or wall assembled from several slabs, then the joints between the slabs must be carefully filled with reinforced tape. For these purposes, you will need a special putty, because ordinary putty, given the "springy" properties of fiberboard, will not work here. An alkyd putty filler copes well with such tasks. Due to its plasticity, it is able to withstand dynamic loads and prevent material deformation or rupture. Putty is applied thin layer, which must be immediately strengthened with a tape, or use a strip of serpyanka for this.

The video tells what fiberboard is and how it is produced:

If the coating has no a large number of seams, you can seal the seams with acrylic-silicone sealant. This material gives a sufficiently strong and waterproof connection and any paint fits well on it.

After the putty is completely dry, you should carefully process the seams with the same fine-grained sandpaper.

The resulting surface must be carefully primed. Without a primer, the surface of the fiberboard will absorb a lot of paint and, moreover, the paint on such a surface will lie unevenly. Use special alkyd solutions or drying oil heated to 50 ° C as a primer. The primer is applied in one layer. It is not recommended to apply a second coat of primer, because this can lead to surface irregularities. In addition, the primer on the fiberboard surface dries for a long time.

Choice of paint

Paint for painting fiberboard can be any: water-based; alkyd; oil; acrylic. If you want to paint your fiberboard floor, you can use the CT (super hard) paint, which is durable. For application on furniture facades or walls, it is recommended to use acrylic or water dispersion paints. When choosing a paint, carefully read its characteristics. Modern manufacturers indicate on the packaging all the necessary information about the methods of application of the paint and about the average consumption when applied to various materials.

For painting the fiberboard completely depends on your taste preferences. Using multiple views paints and varnishes allows you to give the surface a spectacular look. For example, to make the surface look impressive, we take the diluted bitumen varnish and apply it to the surface with a special brush, which gives the surface the desired look. White enamel applied to the fiberboard surface imitates appearance plastic, and water-based paints will make the surface of the slab matte.

Paint application

It is not recommended to use brushes or foam sponge for applying paint to the fiberboard surface. Using these tools will result in uneven paint application and smudging of the surface. Paint should be applied using a roller or spray gun. If the area of ​​the surface to be painted is small, then it makes sense to purchase several cans of paint, complete with sprayers. The main disadvantage of this approach is their high cost.

Coating protection

Modern paints make it possible to form a sufficiently strong coating, well protected from wiping and other mechanical deformations. Therefore, it is not necessary to protect the resulting coating with varnish. At the same time, applying a layer of varnish (or several layers) will not only enhance the reliability of the coating and extend its service life, but also give it a richer and more presentable look.

In conclusion, it should be noted that painting fiberboard products is not the only way decorating them. For example, you can get a reliable and, very importantly, water-repellent coating in the following way: glued to the plates (carefully putty) the usual paper wallpaper without embossing. After the wallpaper has completely dried, the surface is covered with several. Such a floor will last a long time and will reliably protect the room from dampness. An additional advantage such an approach provides a lot of room for design solutions- the floor surface, due to the wallpaper pattern, will have a unique look.

Painting chipboard and fiberboard is a responsible procedure that requires compliance with certain rules. For work, certain formulations are used to achieve optimal results. Due to its structure, the material absorbs the applied solution well, therefore careful preparation is imperative. The place of use of the plates is also important, because this implies different level impact.

To accept correct solution how to paint chipboard or fiberboard, it is necessary to take into account the features of these materials. Although they are almost identical, each has its own structure.

How to paint chipboard and fiberboard?

The choice of paint is very important process, the final type of coating depends on this.

Chipboard paint

The solution is selected taking into account several factors, which depend on the type of surface and external parameters. It is recommended to use the following types of formulations:

Spray paint is a good option. But aerosols do not allow staining large area, therefore, they are used for decoration.

Compositions for fiberboard

Not all types that can be used for chipboard are suitable for fiber boards and panels. For example, water-based paints do not have good adhesion to such a surface, since in fiberboard composition includes paraffin, which repels water. That is why, when choosing acrylic mixtures, a deep penetration primer is additionally selected.

On a note! Moisture resistant chipboards will also require more laborious preparation when choosing water-based formulations.

In addition to water-based emulsion, materials can be coated with the following types of coloring solutions:

Usage budget staff in most cases justified

• Oil. This variety is used less and less because of its toxicity, pungent odor and long drying time.
• Alkyd. A good option suitable for all types of wood-based products.
• Drying oil. It is used as a decorative and moisture-proof impregnation, which is additionally varnished. Stain can be an alternative.

For decorative varieties, a quick-drying, colorless varnish is suitable.

Dyeing technology

The technique of painting different wood-based panels at home has some differences, but the preparation process for all types of materials is common:

Attention! An important condition is the minimum moisture content of the processed material, if necessary, it is dried in advance.

Painting chipboards

Chipboard painting begins with priming. For these purposes, an acrylic composition is used, with which the product is impregnated in several layers, each time waiting for the previous coating to dry completely.

When working with acrylic compounds the soil should be selected similar

Do-it-yourself paint is laid as follows:

1. The mixture can be applied with a roller or spray gun, for hard-to-reach places brushes are used. If the coating has not been primed, then a well-thinned paint is applied.
2. The composition is evenly distributed over the surface, the movements should be in the same direction. The number of layers to be applied varies from 2 to 5. Spraying - more difficult process and requires experience.
3. Once the last coat has dried, varnishing can be carried out for additional protection.

If the spray gun is not available, then the best tool for coloring smooth surfaces there will be a roller

Dyeing wood fiber products

Fiberboard panels are painted in almost the same order as previous works, but it is recommended to use a fur roller or spray gun. Such material can be painted without a primer, then the procedure will be as follows:

1. For the first coat, the mixture is slightly diluted. The paint is applied quickly, without processing the bald spots that appear due to the gradual absorption of the solution.
2. The next layer is laid no earlier than in a day. The mixture should be more viscous.
3. At the final stage, a third layer is applied.

Fiberboard floors are painted in at least 3 layers

On a note! If processing occurs exclusively with varnish, then a suitable shade is chosen, and the number of layers varies from three to six.

Features of working with laminated chipboard

Laminated chipboards are common in the furniture industry. They are quite difficult to paint with your own hands, because upper layer reliably impregnates the base, which excludes the possibility of its removal. But laying the paint directly on the laminated surface is not always a good solution, therefore such material must undergo external grinding in order to create a rough base.
