About GL-6400 Exterior Rustic System Basecoat

GL-6400 is a waterborne exterior acrylic basecoat or sealer that is ultra low in volatile organic compounds (VOC’s) and contains zero hazardous air pollutants (HAP’s).  The chemistry of the GL-6400 is based on exterior grade acrylic polymers and the use of UV absorbers to ensure color fastness.  This basecoat is intended to serve as the underlying layer for both the semi-transparent and opaque pigmented GL-6800 topcoats.  Lastly, it also contains a fungicide/mildewcide to protect and preserve the quality of the wood being treated.
