Barrettine 5lt Water Seal

PRODUCT DESCRIPTION

 Barrettine 5L Water Seal is a high-performance, deep-penetrating silicone water repellent engineered to safeguard exterior porous masonry, brickwork, stone, and concrete against water penetration. Formulated to absorb deeply into the capillaries of the substrate without changing its natural appearance or blocking breathability, it creates a long-lasting barrier against dampness, rain, and frost spalling. Ideal for exterior walls, patios, and paving, it helps keep surfaces clean by inhibiting efflorescence, dirt accumulation, and organic growth such as moss and algae.
