8100 Weatherbond (Sealer

PRODUCT DESCRIPTION

8100 Weatherbond® Sealer is a latex-rich styrene acrylic water-based sealer specially formulated to provide the ultimate protection for finishing coats on exterior surfaces. It features excellent hiding power, which promotes a richer and more vibrant color appearance for the topcoat. This premium sealer is engineered to offer superior resistance against alkalinity and efflorescence, which are common causes of paint discoloration and chalking on exterior walls. Additionally, it provides excellent adhesion, water resistance, and spattering resistance, making it an ideal choice for both new masonry walls and repainting projects. Its ultra-low odor and low VOC formulation also make it an eco-friendly "Green Choice" product.
