Abstract
The present invention relates to a method and a device to improve an aged surface layer (7) of a boarding material (1) to an essentially “newly painted condition”, which boarding material (1) is manufactured from essentially recovered, ground down polymer material (3) and ground down organic fiber (4) having a surface layer (2) which, after a certain time, has been exposed to UV light, weather and wind, cold and heat, and has caused the polymer material (3) to be removed to some extent and to create an aged surface layer (7), which according to the invention is restored indifferent steps. In a first step loose particles are removed from the aged surface layer (7), and in a second step this layer is heated to 160-200 degrees C. by a heating device (8) until the organic fiber (4) has sucked in, by capillary suction, the fluid polymer material (3) containing dye pigment lying underneath the aged surface layer (7), which thereafter is improved to an essentially new condition.
