About Exterior Rustic System Topcoat

GL-6800 is a waterborne exterior acrylic topcoat that is low in volatile compounds (VOC’s) and ultra-low in hazardous air pollutants (HAP’s).  The chemistry of the topcoat is based on exterior grade acrylic polymers and the use of UV absorbers to ensure color fastness.  The exterior longevity of the GL-6400/GL-6800 finish system is remarkable with many rustic exterior surfaces (including log homes and facilities) experiencing up to 10 years of quality service.  Available are both semi-transparent and opaque, pigmented products.
