Flash Harry Waterproofing One Shot 5L + Free Membrane

Durable acrylic and membrane system

• An acrylic compound for waterproofing of iron, or tiled pitched roof applications, skylights, parapets, roof ridges, flashings, and roof screws.
• One shot must be used in conjunction with a waterproofing membrane. As with any liquid and membrane system, the first saturating coat is critical.
• Applying many coats on top of the membrane does not yield proper results.
• Not recommended for areas of long-term ponding or under tiles (fish ponds etc).
• On porous surfaces, a 50% product and water dilution or a bonding liquid, is recommended as a priming coat.
• Do not use to overcoat bitumen waterproofing systems. Ensure compatibility when applying a waterproofing compound over an existing unknown product.
• Not recommended where exposure to negative water pressure is present.
• Clean up with water.
