Barrettine 5lt Water Seal

Product Description

Barrettine Water Seal is a high-performance, clear water-repellent treatment designed to protect porous exterior surfaces from moisture damage and weather decay. Specially formulated to penetrate deep into brickwork, stone, concrete, rendering, and terracotta, it creates an invisible, breathable silicone barrier that repels water while allowing moisture vapor to escape. By stopping water ingress, Barrettine Water Seal helps prevent frost damage, spalling, efflorescence (white salt stains), and the growth of algae or moss without altering the natural appearance of the surface.
