Video: QUESTION OF THE MONTH. Coating Wood Indoors With UV Absorber?
It's that time of the year again - painting is moving seasonally into the interior. This also includes painting on wood. Existing wooden surfaces such as ceilings and / or wall claddings are preferably reworked. It should be borne in mind that the high-energy UV radiation can have a negative effect not only on the outside but also on the inside.
In the colored or opaque area, color changes are rarely noticed. Unless
it is a really massive area exposed to UV radiation. The color of the wood changes in the glazed area, although this in turn strongly depends on the type of wood.
Soft woods show a much stronger change than hard woods. At the latest when you move furniture or hang pictures, this is clearly visible.
For this reason, it also makes sense inside that coating materials are equipped with UV absorbers. Technologically, it is feasible to largely prevent the wood from darkening or yellowing. Already discolored wooden surfaces can be opaque for a visually appealing surface, because UV protection can only be used sensibly on new, untreated wooden substrates!
But how does UV protection actually work?
Basically, it is explained simply: UV rays are absorbed and converted into harmless thermal energy. For this purpose, ZERO-LACK offers the Aqua Holzlasur SLF or Aqua thin-layer glaze. These products contain a UV absorber and can also be diluted with water. This ensures low-odor and environmentally friendly work indoors.
