• resistance to sunlight so that over time the coating does not change color;

Features of the choice of material

For painting windows, it is recommended to choose a material for exterior decoration. The composition for internal restoration is used only indoors. The use of the product is advisable if in the autumn-winter period a defect occurs on the frame that needs to be masked. If the structure is painted inside and out, then only the material for the exterior is suitable.

When choosing a remedy, masters advise considering toxicity. If the frame is being restored, this property does not have much significance, since decoration is carried out with the windows open. Toxic substances immediately disappear without causing harm to the body. When paint is used indoors to mask imperfections, it is important that the composition is not toxic, otherwise the use of the material will cause poisoning.

• after hardening, an attractive glossy film forms on the surface, which improves the appearance of the finish;
• the coating does not change color under the influence of ultraviolet rays;
• The material protects the wood from moisture and changes in air temperature.

The disadvantage is the high price.

Oil
