OSB-boards are usually used for cladding frame or half-timbered houses. That is why the question arises about the decoration of the facade. You can choose siding or ceramic lining, but these options are costly and time-consuming. Coloring will be much cheaper. Different means can be used for this. How to paint an OSB-plate on the street? This is described in the article.
Why paint plates?
To understand whether OSB boards are painted, you should familiarize yourself with their composition and appearance. They are a light, warm material that is used in the construction of external structures, internal walls and partitions. The panels can differ in brands, for the outer part dense products are used, the marking of which has the numbers 3 or 4. Since the material is created by pressing wood chips and glue, it turns out to be breathable, environmentally friendly, but it is sensitive to atmospheric influences.
When creating boards, wood shavings and wood chips are oriented in the extreme parts longitudinally, and in the middle - across the fibers. Because of this, strength and heat-insulating indicators of OSB boards are created. Do I need to paint the OSB-plate on the street? The surface of the material is pleasant and warm to the touch, but has a not very attractive appearance. That is why it needs to be painted.
Another reason for coating with a special tool is the protection of the material, and hence the house, from destruction, moisture, mold, fungi. Although the products are moisture resistant, the joints are vulnerable. Therefore, such facades must be painted. Only before this, dust removal, as well as putty and primer, are absolutely necessary. It is important that there is an exposure between the procedures. After puttying, it takes at least 12 hours to dry. The same period is provided for complete drying of the primer.
Paints
Now many types of paints and varnishes are on sale. But not every one of them is suitable for this material. What to paint the OSB-plate on the street, it is necessary to determine after studying the properties of the paint and the possibilities. When buying, please note that the panels include 90% wood. Therefore, you need to pay attention to the scope of application of the paintwork.
Alkyd
How to paint an OSB-plate on the street to get a high-quality result? Alkyd paint is great for these purposes. It is perfectly absorbed into the wood, dries quickly due to the water component. But with this fact, a lack of funds is associated.
The paint can be stored at a positive temperature, but when hardened, it can withstand frost up to 30 degrees. The disadvantages include a low level of resistance to fires, alkalis. Alkyd paint is in demand due to:
- The absence of an unpleasant odor, harmful formations.
- Dry quickly, preserve color over a long period.
- Excellent hiding power or the ability to get a flat surface without drips.
- Long service life.
- Affordable value.
Acrylic
How to paint an OSB-plate on the street to protect the material from various influences? Acrylic paint with a polymer component, colors and water is suitable. The main property that is required for outdoor service is considered the ability to create a reliable film.
Acres have good adhesion and WWS. These properties influence the demand for facade paints. Manufacturers produce mixtures not only of saturated colors, but also with different physical characteristics. The surface of acrylic paint is matte and glossy, transparent and dull. Such mixtures:
- Dry quickly, very durable.
- Used for treating porous, loose surfaces.
- They have water and vapor impermeability.
- They tolerate significant temperature changes.
Oil
How to paint an OSB-plate on the street so that the material does not deteriorate from various influences? Oil paint is a classic. Compared with modern mixtures, it is less in demand, because it has some harmful properties:
- High toxicity. Protective equipment must be used during operation .
- It takes a long time to dry, since drying oil becomes the basis for obtaining paints.
- It takes experience to apply the product evenly.
- Due to its low resistance, it is often necessary to renew the surface.
The advantages include excellent absorption in the surface, unpretentiousness to storage. Thick paint can be diluted with drying oil.
Latex
What paint to paint OSB-plates for high-quality home protection? Latex paints suitable for wood are used. To create mixtures, ordinary water, acrylic resin, latex polymer liquid substance are used. It is with her that ordinary acrylic enamel becomes a coloring composition.
The basis of the composition is polyvinyl, silicone, other additives to improve performance. Facade paints are created to obtain OSV texture, dense.
Water emulsion
If you are interested, what is the best way to paint OSB-plate, then you should pay attention to water-based paint. It is used to decorate external walls. The tool is suitable for updating concrete and stone materials, which must first be treated with putty and primer. Water emulsions are divided into:
- Silicate. The basis includes liquid potash glass. Paint resistant to steam.
- Silicone They contain silicone resin and fungicidal additives. After drying, they do not allow water to pass through and repel dust and dirt.
The better it is to paint the OSB-plate from the outside, each owner decides independently. The above tools are perfect for this job.
Coloring
These products are considered special, so their processing is not standard. The working surface is even, can be smooth and somewhat rough. Before finishing, the surface should be treated with a special tool.
The edges can be porous, so the pigment is absorbed in an increased amount on them, which will result in color unevenness. Eliminate the defect will be putty for outdoor use. It will remove joints, seams, after which a primer treatment is required. The procedure will improve the adhesion of the dye to the OSB panels. It also protects against harmful effects.
If during installation there were flaws, irregularities, then you need to putty the entire facade. For outdoor use, paint is applied at least 2 times. A better visual result and a more durable surface provides coloring in 3-4 layers.
Staining options
How to paint an OSB plate outside? This work can be done in one of the following ways:
- By spray gun or spray gun. This method is effective for even, durable coverage. Painting with such a device is quick, but increases paint consumption. In addition, the mechanisms are expensive. You can use this method only in calm weather using a respirator.
- Paint brushes. The option is time-consuming, takes a lot of time.
- Paint rollers. To speed up the process, rollers are used. With this tool you can quickly and efficiently update large areas. It is used for different mixes.
Detailed information
The internal surfaces of the OSB boards are treated with a spray. You can take a roller for painting the ceiling with a water-based emulsion. In hard to reach areas, the product is applied with a brush. When applying the first coat, uniformity must be controlled. If you use water-based varnish, then you need to monitor if the boards are spoiled from moisture. Smears should be performed in one direction.
Before applying the next layer, you need to take breaks to dry the surface. To do this, wait 6-8 hours, the time is determined by the types of paint. Drying should be natural at a stable temperature. Drafts should not be allowed.
The outside of the house is exposed to negative factors, so you need to choose high-quality paint for it. Particularly careful attention must be paid to the ends. The sharp edges of the plates should be rounded with a radius of about 4 mm. Then the surface is cleaned of dust and a primer is applied.
When choosing a paint for finishing, you need to pay attention to the aesthetics of transparent varnishes. Many do not tolerate the sun. Water-based paints often deform plates. Organically soluble, alkyd, oily agents will be most suitable. The principle of operation is the same as indoor. But at least 3 layers are applied to the facade.
Nuances
First, you should touch the joints of the OSB plates. Processing of these sites will be positive, but not for long, because during the laying of the house the slabs “play” and the putty cracks and falls out of the seams. This will negatively affect the appearance of the facade. There is another option for the design of narrow sections - the use of decorative overlays. They close the seams after painting. They are needed as a protection and design element.
Paint work is carried out from the top of the wall so that the paint does not flow onto the drying area. You also need to consider the weather. Finishing is preferable to do at a positive air temperature.
It should be remembered that the painted facade during operation is considered unpretentious, but care is still needed. Usually materials are resistant to impacts. Walls should be washed regularly with detergents, unless the manufacturer advises something else. Do not use bristle brushes, as this will damage the finish.
Thus, OSB boards must be processed. Paint will be an affordable and effective option. The house will be reliably protected from various adverse factors.
