QUESTIONS & ANSWERS

A roof coating will stop leaks. It does this by bridging gaps or cracks in roofs, gutters, vents, skylights, etc.
The waterproofing membrane, Belzona 3131 (WG Membrane), does not have a mixing ratio as it is a single component product.
The application of the flexible membrane, Belzona 3131 (WG Membrane), depends on the substrate. Generally, the area must be sturdy, clean, dry, and free of loose material. Then, apply the Belzona product with the recommended sheepskin roller (not foam) for large areas or brushes for small, detailed work. While still wet, lay Belzona 9361 reinforcement sheets onto the surface. Follow up by carefully brushing over the surface to ensure complete wetting and avoid trapped air and creases. Next, apply a second coat of Belzona 3131 (WG Membrane) as soon as possible without disturbing the first coat, preferably within 48 hours. Finally, allow curing.
