The AMES® BWRF1 Block & Wall™ Liquid Rubber is a premium-grade, water-based, elastomeric coating engineered for superior waterproofing and surface protection. Designed for use on basement walls, foundations, and other below-grade surfaces, this product delivers a flexible, durable membrane that resists cracking, peeling, and moisture intrusion.

Product Overview:

Block & Wall™ Liquid Rubber is formulated with high-strength adhesive properties and up to 1800% elongation, allowing it to expand and contract with the surface. It adheres to a wide range of materials including concrete, galvanized steel, aluminum, plywood, and wood, making it ideal for both residential and commercial waterproofing applications

Key Features:

• Superior Waterproofing: Forms a tough, flexible membrane that seals out water and moisture, protecting surfaces from damage and deterioration
• High Elongation: Expands and contracts with the substrate up to 1800%, preventing cracks and maintaining adhesion over time
• Multi-Surface Adhesion: Bonds to concrete, wood, metal, aluminum, galvanized steel, and more without the need for primers
• Semi-Gloss White Finish: Dries to a bright white, smooth semi-gloss finish that enhances visibility and aesthetics
• Eco-Friendly & Safe: Non-toxic, low odor, and VOC compliant in all 50 states. Safe for indoor use and environmentally responsible
