How to paint a plywood: select the material and study the technology for a guaranteed result

Although inexpensive and multipurpose, plywood can be challenging to paint. Getting paint on plywood to look perfect takes the right technique, whether you’re painting furniture or working on a do-it-yourself project.

We’ll walk you through every step of the process in this guide to get a smooth, long-lasting finish on plywood. We’ll go over the crucial steps that really make a difference, from selecting the best paint and primer to perfecting the painting technique.

By implementing these suggestions, you’ll make your plywood surfaces look better and prolong the life of the paint job.

Painting plywood can give an otherwise boring surface a lovely sheen, but professional-looking results need careful prep and the right paint. Long-lasting, smooth surfaces can be achieved by using the right materials and tried-and-true methods. This post will walk you through the steps to make sure your plywood project is well-polished and looks great.

Materials for coloring

Pigments

Several sheets of natural wooden veneer are glued together to create plywood. It is widely used in finishing and construction projects because of these qualities, in addition to being inexpensive and simple to process.

Plywood’s susceptibility to outside factors, especially precipitation and water condensing from the air on the sheathing, is one of its drawbacks.

Because of this, artisans must choose how best to paint plywood to protect it from moisture while still enhancing its aesthetic qualities.

Wood-based interior and facade paints can be used to treat it.

• For interior finishing work, you can use various water-based paints. These are, first of all, acrylic and latex pigments. After a little preparation (we will provide instructions in the corresponding section), the panels can be painted with such compositions without compromising quality.

Counseling! It is important to choose materials with high elasticity when painting plywood on the walls or ceiling because they resist cracking when wood is deformed by extreme temperatures.

• Enamel (pentaphthalic) paints for wood are also suitable for interior work. They are easy to apply, penetrate deeply between the fibers and dry relatively quickly.
• If you are interested in what to paint plywood with outside, then the task becomes more difficult. Experts recommend thoroughly impregnating all the boards with drying oil, and then applying red lead to them. You can already apply alkyd-based enamel on the red lead layer.
• An alternative can be special impregnations based on oils or varnishes with tinting components. In principle, these are not exactly paints, but they cope with the task of protection and decoration perfectly.

Applying impregnation based on varnish

Kindly take note! The quality of the wood composition has a major impact on the price. Purchasing goods from a reputable manufacturer once is preferable to having to replace the plywood every ten years and restore the finish every two or three years.

Auxiliary materials

We’ll need additional resources in addition to the pigments themselves.

For instance, it is also worthwhile to purchase the following when considering what to paint the plywood on the wall:

• Wood putty, which will be used to level the base for painting.
• Polymer-based primer, which ensures penetration into the thickness of the fibers and gives the necessary adhesion.
• Protective varnishes that can be applied over the paint. Most often, varnishing is used when laying plywood on the floor, but wall paneling can also be treated.

Primer with antibacterial qualities

You can get far better results by using a set of materials than by just painting on a piece of plywood that has been sanded.

Processing technology

Preparation for painting

This finishing method requires a lot of work. The main idea is that plywood needs to be prepared in a specific way before it can be painted for the exterior cladding, walls, or floors.

In this instance, the instructions might recommend the following order of actions:

• If the sheathing has not yet been installed, then we cut the sheets of material to size. After cutting, carefully align the edges, getting rid of splinters and burrs.
• Next, we perform a rough cleaning of the material, processing it with sandpaper No. 60 – 80.

You can use specialized mechanisms (shown in the photo) to sand large areas.

• After removing dust from the slabs, we level out all the defects using putty. Quality dry the putty layer.
• Repeat sanding, using a finer abrasive. The optimal choice would be sandpaper No. 100 – 120. To avoid the appearance of new defects, we process the material along the grain.

Counseling! Laminated plywood should be painted using the same sandpaper. To ensure adherence to the primer or paint, we will remove a portion of the lamination using abrasive grains.

Matte lamination is required prior to processing.

• After finishing sanding, impregnate the base with nitrocellulose, alkyd or water-dispersed primers. In most cases, experts recommend choosing a primer that is closest in structure to the decorative material.
• It is also possible to pre-treat wooden boards with antiseptics. However, this is done before applying the last layer of primer.

Painting is the last step you can do after the primer dries.

Application of the composition

Plywood can be painted:

• Brush.
• Roller.
• Spray.

Working with the component using a spray gun

For a brush and roller, paint from a can is usually used undiluted, but for a spray gun, some dilution is necessary. However, using a spray gun is actually more convenient because it applies the layer thinner and works faster.

Counseling! Choose thicker paints with a lot of pigment when painting a plywood ceiling because there will be fewer drips and it will be simpler to mask the sheathing board fastenings.

Painting plywood products is an easy task for anyone who has ever painted something by hand:

• We process only dry material. If the plywood is wet, it cannot be painted – the pigment will not "stick" firmly enough anyway.
• If possible, the boards should be painted on both sides – this way they will deform less during further use.

Painting using a roller

• Apply the first layer of material to the primed boards as thinly as possible. Rub out drops and streaks, avoiding the formation of irregularities.
• You should not try to paint over all the dark areas at once: when using light shades or low-opacity paints, this can only be done through multi-layer processing.
• After applying the paint, give it time to soak in and dry. The drying time depends on the type of pigment used and can range from several hours to a day.
• After the first layer has dried, apply the second and dry again. Repeat the operations until the desired result is achieved.

• In conclusion, we apply a transparent protective varnish to the surface.

Step	Description
Selecting Paint	Choose acrylic or latex paint for durability. These types provide a smooth finish and adhere well to plywood.
Preparing the Surface	Sand the plywood to remove rough spots. Wipe it clean to get rid of dust.
Applying Primer	Use a primer to seal the wood and create a uniform surface for the paint.
Painting	Apply thin, even coats of paint. Allow each coat to dry before applying the next.
Finishing	Once the paint is dry, consider adding a clear protective finish for added durability.

If you know what supplies to use and are aware of the steps involved, painting plywood can be an easy and satisfying process. A smooth, durable finish depends on a properly prepared surface, which can be achieved by selecting the appropriate paint and primer.

All the way from sanding to applying the last coat, take your time. The result can be greatly altered by paying attention to small details like evenly spaced brushstrokes and sufficient drying time in between layers.

With these easy pointers and methods, you’ll be able to paint plywood with confidence, knowing that the finished product will be long-lasting and aesthetically pleasing.
