Plywood than better to cover. Various ways to paint plywood

For many years, one of the most common flooring is plywood. It attracts, first of all, with an affordable price. And the fact that it is a natural, strong and durable material only adds to its popularity. In most cases, it is used as a substrate for more modern materials, such as: carpet, and. But it is also allowed to use it as a finishing decorative coating.

To figure out how to properly cover the floor with plywood, here are a number of basic rules:

Before laying, the sheets are brought into the room where the installation will be carried out and left there for acclimatization.
If the base (cement or screed) is not even and there are significant differences on the surface, it is better to cut plywood sheets into squares 50-100 cm. In this case, voids will not form under the sheets, in which a fungus can start over time. For an even base, laying in solid sheets is allowed.
Before laying the base must be cleaned of debris and dust, if necessary, carry out wet cleaning.
The next step is primer. If you plan to use ordinary plywood, you need to cover the floor with a moisture resistant primer, preferably with antifungal effect (especially in wet rooms). When using moisture resistant plywood, ordinary soil will do.
The choice of glue also plays a big role, it happens: water-dispersion, polyurethane, epoxy. Read more.
In addition to glue, sheets must be fixed with self-tapping screws, this is especially important when using water-based glue. Self-tapping screws with plastic dowels are best suited for this purpose. Hats should be medium size, preferably galvanized.

step by step coloring

After finishing preliminary works the question arises: how to cover the plywood on the floor? For these purposes, you can use paint or varnish (or all together). Each of these methods has its pros and cons.

In any case, there is a certain algorithm of work that increases operational plywood properties:

Grinding - can be carried out,. preliminary is being done coarse-grained sandpaper across the veneer fibers. If subsequently it is planned to apply varnish, then additional grinding is carried out with fine-grained sandpaper along the fibers.

Particular attention should be paid to joints, knots and other problem areas. If necessary, apply putty.

The priming procedure is most often done using an acrylic or alkyd primer. These works can only be carried out on a dry surface. If you plan to apply only varnish, then there should be at least 2-3 layers of primer.

Painting is one of the most important stages of installation. Painting is carried out only on a well-dried surface. Depending on the selected materials, temperature and humidity of the room, the final drying of the primer may take several days..

There are several types of paints that may be suitable for these purposes:

acrylic - are made water-based, harmless to health, odorless, easy to apply and dry quickly;
alkyd - solvent-based, there is a pungent odor during the painting process (work better using protective equipment: respirator, goggles, gloves), have a more viscous structure, dry longer.

Lacquering plywood

Varnish is applied either on primed surface, or on a painted one (if the paint is glossy, then you can do without a varnish layer). This protective layer can be alkyd-urethane or urethane based.

The first option differs in value for money. The rest belong to wear-resistant types, but cost a little more. For the best effect, the varnish should be applied in 2-3 layers with the time interval specified in the instructions.

Each layer dries for about five hours, and walking on the surface is allowed after a day. It will take about 4 days to completely dry, and when using a water-based varnish, the floor will dry completely after a week.

There are times when appearance is not so important, but the main goal is to solve the issue: how to cover plywood on the floor for moisture resistance. Here the well-known drying oil will come to the rescue. You can buy it at any hardware store. You need to take it with a margin, so that the surface is not just covered, but soaked through.

Tools

Painting and varnishing work can be done with a roller (with a lint-free surface) or with a brush. If the scope of work is large and there are many corners on the surface, and hard-to-reach places, you can use a spray gun or a soft sponge. Empty containers will also come in handy: a cuvette or simple buckets, basins.

Plywood is used quite often in modern construction and repair, so painting plywood is a very topical issue. The peculiarity of this material is in the method of its production. For its manufacture, thin sheets of veneer are glued together. The adhesive composition used determines the characteristics of the material, such as its moisture resistance. Depending on the degree of resistance to moisture, plywood can be ordinary, moisture resistant or laminated.

Painting helps protect plywood from rot and moisture, as well as prolong its life.

Preparing for painting

You can extend the life of the base by painting it. Before painting plywood, it is necessary to prepare its surface for applying the coloring composition. The purpose of the preparation is to achieve maximum smoothness and evenness of the surface.

Plywood painting is carried out in stages. First you need to sand it with #80 sandpaper. After that, an acrylic-based primer is applied and left to dry completely. On the dried primer, putty for wood, made on the basis of acrylic, is applied, as well as a primer. The leveling layer must also dry completely. After drying, it is polished with emery No. 80-120. The surface is again primed, dried and painted.

The primer is used to protect the substrate from fungus. The primer is applied with a roller. You can not engage in alignment if no special requirements are put forward for its relief. In this case, the material is primed and painted.

Grinding allows you to eliminate irregularities from the surface and prepare it for further processing. It is necessary to perform movements with emery perpendicular to the direction of the wood texture. If further processing involves opening with varnish, then it will also be necessary to perform grinding along the wood fibers with fine-grained emery. The edges of the material can be lightly planed towards the center. They are covered with 2-3 layers of acrylic paint.

The surface is primed and putty for the following purposes:

leveling the surface capable of absorption;
filling cracks on the inner surface of the veneer;
extending the life of the material;
damage protection.

How and with what to paint plywood?

The choice of coloring composition and method of staining directly depends on the purpose of the material.

The main task of painting is to prevent cracking of the material. If the plywood will be laid on the floor in a room with high humidity, then it is necessary to cover it with paint on both sides, and process the edges especially carefully, they need to be applied several layers of the composition.

How to paint plywood depends on the place of work. If this is a residential area, then it is recommended to choose compositions on water based. Well, in this case, acrylic is suitable. On the prepared surface, it is applied easily and dries quickly, while it almost does not have an unpleasant odor.

If the material will be used outdoors, then the best option is pentaphthalic paint, which is a common enamel coating for wooden surfaces. The composition is applied easily and dries quickly.

You can purchase a ready-made composition, but if you wish, you can stop at the basic version and tint the composition yourself. Before painting plywood, you need to make sure that it does not have excessive moisture. If the material has been stored in high humidity conditions, then it must be dried before processing to a normal humidity value.

To create an attractive glossy surface, plywood on the floor can be additionally varnished. This is not necessary if glossy paint is used. The paint on the surface of the material must dry completely.

It is very important to decide in advance how to paint the plywood on the floor. The best option- sprayer. It helps to achieve even coverage. You can use a roller, but only without lint, but with foam rubber. If necessary, paint hard-to-reach places with a brush.

Thus, before painting plywood, it must be prepared for applying the coloring composition. Certain compositions are selected to cover the base. Processing methods depend on the purpose of the material.

Plywood is actively used in the manufacture of furniture, in interior decoration, for rough and finish floors. It is relatively inexpensive, clean in environmental plan, easy to process material. natural origin - the best of that proof. But it must be protected from moisture penetration and additional measures must be taken to make the plywood surface more attractive. appearance. The simplest solution is to paint the plywood with acrylic paint or other wood-friendly paint.

How to prepare a surface for painting

It will not be superfluous to recall that only well-dried sheets of plywood should be taken into work. If the material was stored in conditions of high humidity or on the street, then it should certainly be dried. For this you do not need to use special equipment. It is quite enough to lay out the sheets in a warm, dry room before installation and stand for 7-10 days. It is also necessary to treat the wrong side of each sheet with an antiseptic composition, you can cover it with drying oil, and then perform installation work.

Before painting the plywood inside the house, you need to prepare its surface. Namely:

The first stage of preparation is grinding. The work must be carried out in two approaches. First, treat the surface with a coarse abrasive, then with a fine one. Grinding can be done manually using sandpaper, a grinder or a grinder with the appropriate nozzle. The edges of the sheets should be handled with special care.
Then you need to clean the sanded plywood from dust and small waste. This work should be done with a soft brush or dry cloth. If possible, using a vacuum cleaner is the best option.
Soak with an antiseptic and, after drying, cover with a primer. It is most reliable to use a universal material or from the company whose paint is planned to be used for finishing.
This stage is very important, because plywood, just like any other type of wood product, is exposed to moisture. Antiseptic and impregnation with a primer will give the surface increased resistance to the appearance of fungi, mold.
After priming, it is necessary to carefully inspect the surface for the presence of wood pile. If necessary, repeat the final sanding with fine sandpaper and prime again. In fairness, it should be said that now manufacturers supply plywood to the distribution network in finished form. That is, sanded and primed. However, this material is much more expensive than conventional plywood.

Preparation of tools and coloring composition

How to paint plywood? There are no restrictions here. You can use the tool that is more familiar. The configuration of the surface and the presence of hard-to-reach places that are treated with a paint brush are important. Solid planes are covered with a lint-free roller or with a spray gun. It is worth preparing a paint tray, since it is inconvenient to paint plywood with a roller from a can. Several options can be offered to select the correct paint.

Since plywood is usually used indoors, water-based paints, most often acrylic, are used for its coloring. There are ready-made formulations on sale, but you can purchase a white dye and give it the desired shade by adding pigment. In this case, it is necessary to prepare at once the entire amount of paint that will be needed to cover the entire intended volume. Practice shows that approximately 115 grams of dye is consumed to cover 1 m2 of surface. Paint for plywood must have elastic properties, since the material is "breathable", it can shrink and expand with temperature changes.
Glazing compositions are excellent for coloring plywood. They are useful when it is necessary to emphasize the texture of wood and make it brighter and more noticeable.
It is not forbidden to use stains and water-based wood varnishes. In this case, the surface can be given the desired shade and make it glossy.

clean plywood floor

Most often, plywood is used as a preparation for a permanent coating. But there are exceptions when finishing floors are made from this material. In this case, they require thorough protection from moisture. Sanding and priming is not enough here. Before painting the plywood on the floor, it is necessary to perform a continuous puttying with acrylic putty on wood. Thereby:

reliably monolithic all joints and cracks, since the end sides of plywood sheets are the most vulnerable;
level the plywood surface, hiding cracks, other defects;
increase the service life of plywood trim or items made from it.

After the putty has dried, the surface should be sanded and coated again with a primer. Dry and you can start painting. From the wide range of paints for wood, you should choose a water-based dye that can create an elastic film on the painted surface.

The nuances of painting the plywood surface

How to paint plywood? The coloring composition must be applied in an even layer, along the wood fibers. When choosing a tool, it must be borne in mind that it is more convenient to cover a large area with dye using an airbrush or spray gun. At the same time, be sure to cover items that are not to be stained with foil or old fabrics.

The roller paints solid surfaces of medium size. A fur or fleecy cover should not be used, it can leave a pile on the paint. A foam roller works best. It is more convenient to paint the end parts of plywood sheets, corners and reliefs with a paint brush.

Applying a thick layer of paint should be avoided to prevent smudges and sagging. It is better to paint in several thin layers, allowing enough time for each to dry. This is the only way to get a beautiful and uniform coloring.

Plywood is an environmentally friendly, durable and inexpensive material that is currently very common. It is used for the manufacture of partitions, furniture and flooring. Plywood sheets consist of sheets of wood veneer that are held together with a special mixture. When processing this construction material does not require much effort. Moreover, products made from plywood have a very attractive appearance, and especially after it is painted. Painting plywood sheets does not require skills and does not cause difficulties. How to paint plywood and how to do it right - we'll talk in this article.

What to paint?

The main task of painting plywood is to protect it from cracking. How to paint plywood? The choice of dye depends on the purpose of the sheets and the place of their operation.

Paints

Paints by type of thinners are divided into the following types:

Water-dispersion. Diluted with water. Odorless, environmentally friendly, forms a strong thin film after drying.
Alkyd. Differs in the high durability and preservation of appearance long time. The disadvantages are that they are dissolved with turpentine, white spirit, drying oil, which have pungent odors. It is best to use this type for outdoor use.

Important! This type is suitable for protecting plywood sheets from moisture.

Water-dispersion paints are further divided into the following types:

Water emulsion. Resistant to temperature extremes, non-toxic, applied to almost any surface, other types of paints easily fall on them.
Latex. Resistant to abrasion, close cracks up to 1 mm, moisture resistant and create a glossy finish. The disadvantage of this type is the possibility of mold and fungus formation, as well as intolerance to low temperatures.
silicate. They have a high level of quality and a relatively low price. Disadvantages - incompatibility with other types of paints and the presence of alkali in the composition, which requires compliance with safety measures when working with this type of paint.
Silicone. They hide cracks up to 2 mm, provide a high level of elastic coating, are durable, with a water-repellent effect, and are also resistant to temperature extremes. The downside is the high cost.
Acrylic. Resistant to moisture and create a high-quality layer when dried.
Polyvinyl acetate. Suitable for rooms with low humidity. May acquire a yellow tint over time.

Plywood painting in living quarters is done using water-based paints. This category includes acrylic paints, which are endowed with the following properties:

Dry quickly.
They do not have odors.
Fit comfortably.

How to paint plywood for the street? Ordinary enamel for wood products, which is easy to apply, is perfect. This type of coating is sold both in a ready-made color solution, and it is possible to perform tinting.

Important! Plywood boards must be dry before painting.

Lucky

Also on the building materials market there are varnishes that can be used to paint plywood. There are two groups of varnishes, which differ in the way the layers appear:

Layers are formed in the process of polycondensation and polymerization. The varnish layer is hardening. They are made on polyester, oil, urea-formaldehyde and polyurethane bases.
The layers are formed due to weathering of the solvent. Such varnishes are made on the basis of nitrocellulose or alcohol.

Important! How to paint plywood correctly to emphasize and refresh the natural texture of a plywood sheet? To do this, it is necessary to paint the surface completely, without intentionally emphasizing the uniqueness of the texture on the veneer.

The most popular manufacturers of varnishes and paints:

Galamix.
Alpina.
Dufa.
Ceresit.
caparol.
Bayris AQUALAK.
TIKKURILA.

Preparatory work

Painting plywood is necessary to extend its service life. Before painting this building material, it must be properly processed.

Important! After buying plywood, leave it to dry for a while. To do this, place the sheets in a warm room with dry air.

Plywood base preparation provides:

Moisture resistance.
Strength.
Smooth, beautiful surface.
Longer service life.

The processing process consists of the following steps:

Grinding.
Padding.
Drying.
Puttying and drying.
Grinding.
Padding.
Coloring.

Before answering the question of how to paint plywood, we will consider all the steps in more detail.

Grinding process

After drying, you can proceed to grinding. For this:

Sand the top of the material perpendicular to its structure with coarse sandpaper (#80-100).
Then use fine-grained sandpaper to make the surface perfectly even.
The edges of the plywood need to be planed from the edge to the center, and then coated with acrylic paint.
Repeat the painting process 2-3 times.

Primer and putty

The process of priming and putty is necessary for:

Leveling a wooden surface.
Closing cracks on the inside of the surface.
Protection against mechanical damage and extension of service life.
Better adhesion of paint to the surface.

After priming, let the surface dry. To eliminate the appearance of a blue tint and mold, treat the sheets with antiseptics and fire retardants.

Important! These funds will protect plywood from fire.

If there are large dents or cracks on the plywood surface, they must be leveled using wood putty. Also, for extra strength, you can cover the entire base with putty. After - it is necessary to dry the sheet thoroughly.

Re-alignment

After the putty has dried, in order to remove small irregularities, it is necessary to grind with fine-grained sandpaper to the desired smoothness of the surface.

Important! Remove dust after completing this step.

Re-priming

Apply primer in 2-3 coats to increase adhesion with the dye. Dry the plywood sheets thoroughly.

Painting

How to paint plywood white is of interest to many. The method of applying paint does not depend on the color, it depends on the composition of the base that is being painted.

Tools needed for coloring

To properly paint plywood, you need to prepare the tools that will be needed in the process:

Spray.
roller.
Paint brush.

The area and type of surface to be painted will depend on which tool to use:

Use a spray gun to save time when painting large flat areas. With it, you can achieve a high level of quality painting.
The roller is suitable for painting medium-sized flat surfaces.

Important! It is best to use foam rubber.

Corners, ends and various curly elements are most conveniently painted with a paint brush.

Important! Cover furniture and flooring with film to avoid contamination during painting.
