Wood is a traditional building material and has many advantages. But it also has significant drawbacks - an extremely negative reaction to atmospheric precipitation. The tree absorbs moisture, rots and is affected by pests. After an increase in relative humidity, it significantly increases in size, during freezing / thawing of wet structures, the integrity of the upper decorative coating is disturbed. In connection with such features, increased requirements are imposed on wood paints for outdoor work.
Wear-resistant wood paint for outdoor use
In this article we list the best decorative coatings and reveal the secret of how to do it right wood paint for outdoor use is applied to the surface of the facade, wear-resistant.
A variety of compositions can be used to decorate wooden walls
When working with paint, do not neglect respiratory protection
To paint on wood for Internal work imposes strict environmental requirements; for external work, it is allowed to use dyes that release harmful chemical compounds into the air. Due to this "relaxation", manufacturers can produce products with improved characteristics.
Paint for outdoor use has good resistance to weathering
Another difference is plasticity. Wooden structures operating in the open air are subject to cyclic freezing / thawing, their linear dimensions to a greater extent fluctuate.
Outdoor paints should compensate for these factors, respectively, have increased plasticity. As for wear resistance, it equally depends on the physical characteristics of the paint and the accuracy of adherence to the recommended application technologies. Without exception, all manufacturers are making every effort to increase wear resistance, but you must remember that paints are much inferior to other building materials and technologies in this indicator.

Currently, both traditional and innovative dyes are used to paint wooden elements. Physical characteristics vary with material of manufacture, chemical composition and the presence of special additives.
|The most traditional formulations are made on the basis of natural (drying oil) or artificial (from petroleum products) oils. In terms of wear resistance, they are located in the middle segment. Subject to the recommended rules of application and operation, they can last up to ten years. The cost is one of the lowest. The disadvantage is the difficulty of removing the old layer when repainting surfaces.|
|In terms of wear resistance they occupy a leading position, perfectly resist atmospheric factors , subzero temperatures and ultraviolet rays. Universal use, service life exceeding ten years.|
| Produced with a wide range of colors, are resistant to impact negative factors, do not allow moisture to pass through. Disadvantage - surfaces have a strong unpleasant odor for a long time. Covering for external work.
|The dyes most used by developers, in all respects meet modern requirements. Cost in average parameters, universal use.|
In addition to the base of the paint, you need to pay attention to the manufacturers, the operational properties of the paints largely depend on their conscientiousness.
Produces paints of all colors for both external and internal use. The best are polyurethane-acrylate and alkyd-urethane compounds.
The assortment includes over 20 shades of various colors.
A distinctive feature is high resistance to ultraviolet rays. Withstands at least 50 freeze / thaw cycles. The composition contains additives that prevent the growth of fungi and rot. An excellent wear resistant option for painting wooden structures outside buildings.
A concern from England, admits paints and varnishes based on organic solvents. The coating is durable and beautiful, additionally protects the wood from rotting processes.
Most modern companies produce deep penetration paints - the adhesion coefficient of the composition significantly increases with wooden surfaces. There are brands containing anti-rotting impregnation . When choosing a specific brand of paint, pay attention to a set of characteristics.As for domestic manufacturers, everything here depends on the source materials and the availability of an official license. Those companies that use imported components produce quality products.
The rest conquer the consumer market with a low price and the same low quality. For exterior work, we recommend using only proven paints.
The table shows well-known brands of German wear-resistant paints for painting external wooden surfaces.
|Paint name||Brief description of properties|
| It is used for both external and internal work, it is made on the basis of vegetable oils.
The surface is silky-matt, exhibits the structure of wood, and has high adhesion to wood. Allows the wood to "breathe" a little - excess moisture leaves after getting wet, the probability of swelling is minimized. Color pigments do not change the original color for the entire period of operation.
| Shelf life two years, applicable to all types of wood outdoors. It retains its elasticity for a long time - the risks of cracking are minimized.
Due to polymerization, a durable surface with increased wear resistance is created. The time of complete drying, depending on climatic conditions, ranges from 3-5 hours.
| Special protective colored glaze, has more than 40 shades and flowers. Repels water, reduces the degree of wood wetting. Based on natural oils, it deeply penetrates the open pores of lumber.
It is considered a prophylactic remedy against rot, blue stain and mold. No sanding of the old layer is required when recoating.
|The surface is silky matt, protects the surface of lumber from the negative effects of atmospheric factors, with increased resistance to harsh ultraviolet rays. Colored pigments do not change color throughout the entire period of operation, the paint does not flake or crack, and reduces the drying of wood under the influence of direct sunlight.|
| The oil used during production goes through a preliminary polymer dispersion - the transitions from aged sawn timber to fresh areas are leveled.
Dries quickly, repels water, does not accumulate dust. The surfaces covered with this paint are easy to maintain. When using a primer, one coat is sufficient to obtain an even color. Emphasizes the natural structure of wood, universal use.
| Gives the wood surface a metallic shade - one of the most demanded paints during the creation of high-tech wooden structures.
Due to its high plasticity, it withstands significant dynamic forces, reliably protects the surface of sawn timber from moisture penetration. Not afraid of ultraviolet rays, chemically inert. It can be used both for painting wooden products outdoors and indoors.

This list is advisory in nature, you can choose for yourself other options that best meet the characteristics of wooden structures and financial capabilities. Keep in mind that the operating time of expensive imported paints can be several times higher than that of domestic products.
The final quality of the coatings largely depends on the correct choice of tools. How can wooden surfaces be painted?
We strongly discourage the use of this tool, prohibit such painting technology for hired craftsmen. The productivity of the rollers increases markedly, but the surface quality is far from expected.
Diluting thick paint to liquid is not always allowed, do not rush to experiment on your own.
It is difficult and time-consuming to paint with brushes, but the end result will fully justify the effort.
Important. Buy only high-quality brushes, check the strength of the pile attachment. Dip it in paint before use and apply a few strokes over the surface with great effort - loose fibers will remain on the boards.
Pneumatic airbrushes, spray guns, texture guns
Manufacturers give specific recommendations, but there is also a general algorithm for all materials.
If there are large dents in the cans or traces of fresh paint on the lid, look for a new product.
Check the integrity of the container before purchasing paint
Big problems can arise if you have to use several cans of material to paint one wooden structure. Each of them may have a different shade; heterogeneous areas will appear on the surface.
Stir the paint thoroughly before use
As soon as you notice that it curls up, do not use this solvent.
Mix the solvent and a small amount of paint as testing
Do not violate the preparation technology, inept or illiterate actions can spoil the paint.
We have already said above which tool is better to use when painting wooden surfaces with wear-resistant paints on wood for outdoor use, now you should give some practical advice on the process itself.
Step 1. Selecting the type of wear-resistant paint and antiseptic.
If you are planning to paint the wooden steps of the front porch, then you should buy the most expensive and durable paints. We advise you to buy goods from German or Finnish companies. You should not pay attention to the high price, it will fully pay off with a long service life. Not to mention the excellent design characteristics of these materials. All lumber for outdoor installation must be thoroughly impregnated with antiseptics, you can also use domestic ones, their quality is at the proper level.
The impregnations Elkon, Aquatex and Biosept have good reviews.
Step 2. Surface preparation.
The walls of a wooden house need cleaning and grinding
Wood before processing
Sawn timber must be cleaned of dirt and sanded. Large flat surfaces are sanded with electric machines, the rest will have to be processed manually.
Use coarse sanding paper at the beginning, and work fine at the finish. Remove dust with a vacuum cleaner or compressor. Keep in mind that dust residues will surely fall into the top layer and become noticeable; all uncharacteristic inclusions are clearly visible on the paint. It is difficult to get rid of them, you will have to either remove or grind the area with a rough outer surface and re-cover it. And you can't leave in this state, especially if the marriage is on floor coverings or steps.
No hard-wearing exterior paint can handle the stress of sharp edges. Especially if people walk on them.
Grinding the walls of a log house
If the wooden structures are prefabricated, it is recommended to paint the places of invisible joints before connecting the individual elements.
Applying paint to the joints of lumber
Or, in extreme cases, treat them with antiseptics. This applies, for example, to the installation of balusters on steps, railings, etc.
During slanting rain, moisture enters small cracks, which causes accelerated damage to lumber, and the paint eliminates the likelihood of such situations. The paints should be applied only to dry surfaces, after rain, you need to wait at least three days for the surface to dry completely.
Important Notes About Primer
Step 3. Prepare paints and tools.
Protect surfaces that should not be sprayed with paint
Prepare tools for work
Start painting the surfaces from the opposite side to the exit.
Work with a large and small brush, and carefully inspect surfaces for gaps. Remember to rub in the paint, not smudge.
Dip the brush into the paint half the length of the bristles

Paint the corners with a narrow brush
Step 4. Apply the second coat of paint in a timely manner.
Experienced painters do not allow it to dry completely, due to this, the adhesion strength between the layers is noticeably increased.
Run your hand over the surface of the product, if it slips with a creak, then it's time to apply a second layer of dye. Do not paint in windy weather, as dust can get on the surface of the paint.
Apply a second coat of paint
Careful work is necessary when painting all surfaces, but external ones require special attention.We have already mentioned that the durability of the coating depends not only on the physical properties of the paint, but also on the conscientiousness of the painter.
If it becomes necessary to take a break from work, then tightly close the container with paint.
In order to make the border of the end of the painting invisible, stretch it as much as possible over the surface with a semi-dry brush. The layer thickness in this area should not exceed half the final coat.
Soak brush in solvent
Always follow safety precautions. Remember that exterior paints can contain highly toxic compounds. Due to their use, the performance characteristics of coatings are improved.
Even on the street you can get poisoned by fumes, it is advisable to protect the respiratory system. This is especially true for people with low immunity, chronic illnesses or obvious signs of allergic reactions.
Use a respirator
Do not work near open flames. All paints burn, the only exceptions are special fireproof ones. But they are used for completely different purposes and are never used as a finishing decorative coating.
For the first paint application, dip the brush into the container about half the length. There must be enough material on it to ensure the deepest possible impregnation. If you do not do this, then the second layer will no longer be absorbed into the lumber, the adhesion strength will significantly decrease.
Do not immerse the brush completely in the paint
If you plan to use light colors, then the impregnations should be the same. On dark ones, brush marks will be visible.
Pay attention to the consistency of the material. It should allow the paint to soak into the wood, and the thickness of the remaining layer should allow for natural leveling. If this condition is not observed, then traces of villi will be visible on the surface. You will have to delete them several times. In addition, the thickness of the second coating will vary, which will reduce performance.
Be sure to close up deep cracks in the boards, water gets into them, and wood decay begins in nearby areas. Don't expect the paint to tighten them. Until it dries, the cracks will be invisible, and as soon as the layer dries, the cracks will appear again. Use special wood fillers to eliminate cracks.
Repair any cracks in the wood
In some articles you can find the statement that the choice of wear-resistant paint should be made taking into account the type of wood.
This is not true, there are no separate colors for pine, birch or oak. We have already said by what criteria materials for outdoor work are selected.
It is necessary to renew the paint only after removing all problem areas with the old paint. At the slightest suspicion of peeling, the paint should be removed with a spatula or sanded.Keep in mind that imperceptible micro-cracks on the old surface will rise and become visible.
This happens due to the fact that the new paint softens the old one a little, compression forces appear and the edges of the paint that have lagged behind the surface rise.
And the last thing. The durability of wear-resistant paint depends on the cleanliness of the area. If you always have sand or dirt in front of your entrance, then they will definitely fall on the paint with all the negative consequences for the surface. Remember that cutting wheels for metal are made from sand, while paints have far from such hardness indicators.
