Armawall Sealer Bonder is a first step in the Armawall Texture Coating System which can prime, seal, or even out the substrate's absorption rate prior to the application of a texture. Sealer Bonder is a premium solvent based acrylic blend, which penetrates into masonry surfaces to promote adhesion of water based topcoats. Provides excellent intercoat adhesion to a variety of topcoats, and is fast drying so there is less time needed between coats.
