Water uptake of wood surfaces with and without coating: influence of weathering
2012 - IRG/WP 12-40580
The objective of this study was to compare liquid water absorption of wood surfaces with and without coating, before and after artificial weathering. Samples of spruce, oak and sapelli were exposed to the EN 927-6 cycle for 1500 and 1850 hours and to the weathering produced by the Garner wheel for 1000 hours. Two highly pigmented coatings (solventborne and waterborne) and two semi-transparent stai...

Influence of coatings on water uptake of wood surfaces before and after natural and artificial weathering
2013 - IRG/WP 13-40641
Liquid water absorption of wood surfaces with and without coating, before and after exposure to artificial and natural weathering has been studied. Spruce, oak and sapele samples have been exposed to the cycle of EN 927-6, to the cycle of the Gardner wheel and to natural weathering. Five coatings were tested including solventborne and waterborne, semi-transparent and opaque products. Exposure to w...
