Before deciding on a coating, consider the effect you want to achieve and perform the preparation of the substrate well because that is essential. Before you start putting the new coat of protection, first you need to take off the current one that is damaged. You need to do this very carefully by grinding wood and joints. You need to make sure you took off the protective layer and maybe a little bit of the damaged layer of the wood but you shouldn’t take too much off.

A special priming coating that regulates moisture in the wood should be applied. It will prevent the drying of the wood and the adhesion of the doors and the windows.

Before choosing a coating, consult with dealers in specialized stores. It is important to choose the coating that best suits your needs and which will best protect your carpentry. Recently, numerous ecological coatings can be found on our market, some of them are based on natural waxes and oils that are completely harmless to use. The choice is yours but think carefully before making the final decision.


If we want the texture of the wood to remain visible, and the color as natural as possible, it is best to opt for the lazure paint. These are less pigmented coatings that create a thin film on the tree and transparently shade the surface of the wood. They are water-repellent and very permeable so they allow the tree to “breathe”, which, on the one hand, is very good.


On the other hand, this means that the wood’s moisture varies more than in other, impermeable or semipermeable coatings. Due to atmospheric influences, the larvae are relatively easily eroded so that the layer that protects the wood is thinner and diminishing, but their advantage is relatively easy to regenerate.


If we want to completely cover the texture of the wood and its possible defects, then the best choice is enamel, coatings that contain a large number of pigments so the choice of shades is very large. Enamels are water-repellent and poorly vapor-permeable, which is at the same time virtue and defect. Namely, due to exposure to weather effects, over time, there is a collapse of the coating, creating a micro-crack in a thin film through which moisture penetrates the wood. When the amount of accumulated moisture becomes too large, the film coating is swollen, firing and peeling.


Similar problems occur in varnishes, which represent enamels without pigments. When using, special attention should be paid to UV protection because they do not contain any pigments or fillers, so UV absorbers should be added.


Protection against UV radiation is important because all components of the wood are sensitive, and especially lignin. Due to the rinsing with water and the effects of UV rays, its degradation occurs, the wood gets gray and it can even come to the defect of the wood. The more exposed the light is, the greater the degradation.
