Silcor 560 HB is a single-component, solvent-based polyurethane waterproofing membrane designed for internal and external applications where a tough, flexible barrier is required. It forms a seamless, high-performance waterproofing layer ideal for use beneath screeds, tiles, and protective overlays.
This moisture-curing formulation offers excellent crack-bridging, strong adhesion to primed concrete and screeds, and long-term durability. It’s suitable for use in both residential and commercial projects, including bathrooms, balconies, podiums, and retaining walls.
Silcor 560 HB is easy to apply by roller or brush and cures to form a robust, elastic membrane resistant to water ingress and mild chemicals.
