ABSTRACT:
Disclosed is a method for providing a wood substrate with durability against weathering comprising at least two steps (A) and (B). Step (A) consists of appying to the wood substrate a transparent treatment comprising an organosilicon-containing compound having at least one hydrolyzable silyl group in a carrier for said compound. Step (B) consists of thereafter coating the wood substrate with a transparent, film-forming, coating composition. The coating composition is characterized in that a transparent free film from the coating composition retains an elongation of at least 20 percent after at least 1,000 hours exposure in a Xenon Weatherometer.
