WMA Aquastatic Epoxy is a two-part, water-based epoxy primer and moisture barrier designed to enhance adhesion and protect concrete substrates. It provides a tough, durable, and waterproof coating that can be applied to damp or green concrete, making it ideal for areas where moisture tolerance is critical.

This solvent-free, low-odour system offers strong chemical resistance and excellent adhesion to a wide range of surfaces. It can be used as a standalone waterproof coating, a primer beneath membranes, or a barrier on concrete subject to residual moisture.

Aquastatic Epoxy is suitable for use in both internal and external applications such as basements, retaining walls, and wet areas. Once cured, it forms a seamless, vapour-resistant surface that prevents blistering, delamination, and moisture ingress in concrete structures.
