Exterior Wall Seal

Everbuild 408 Super Seal is a high-performance solvent-based water repellent designed to protect porous exterior surfaces from water penetration. Formerly known as Exterior Wall Seal, this transparent treatment provides long-lasting protection for brick, stone, concrete, plaster, plasterboard, pebbledash, rendering, porous tiling and grouting. The formula penetrates deep into treated surfaces and chemically bonds to create an effective water-repellent barrier that lasts for many years. This specialist sealant is unaffected by ultraviolet light, ensuring the protection remains stable in outdoor conditions. Super Seal is particularly suitable for preventing water damage on exterior walls and porous masonry substrates. It offers improved water beading performance compared to traditional solvent-based products, helping to keep treated surfaces drier and reduce moisture-related deterioration.

Features and Benefits:

• Chemically bonds to substrates for long-lasting water repellency
• Transparent finish maintains natural appearance of surfaces
