There was also tested the impact of beech wood surface pre-treatment with a colorant-based mordant. The measured and calculated values revealed that the major colour changes occurred during the first 100 hours of the accelerated ageing process. The lacquer types used varied according to their success to protect wood surface against UV radiation effects. The lacquers without protective agents against UV radiation could not inhibit beech wood photo-degradation when applied on this wood. Oppositely, the colour changes were even more pronounced than in case of the native wood. This was due to the photo-degradation of the coating material and of the wood surface. Protective agents against UV radiation added into coating materials had significant retarding effects on photo-degradation of the surface-treated wood. Positive impact on colour stability of wood surface treated with the tested lacquers was also found for the pre-treatment with a mordent manufactured based on special light-resistant colorants.
