Environmentally-friendly water-based surface coatings are used as finishing materials – both non-transparent paints and transparent stains. Wooden parts of windows are treated with water-based paints and stains in three stages: treatment, priming and application of top coating.

Non-transparent paints used for wooden window coating are usually chosen from RAL industrial colour chart. Colour may also be chosen from other colour charts, but in this case we do not guarantee the resulting quality. Stains may be chosen from the Remmers colour chart. All aluminium profile systems in wooden-aluminium windows are dry coated. Dry coating is performed on the basis of the RAL colour chart.
