Duroproof PUM PRO is a premium-grade, single-component polyurethane membrane designed for long-term waterproofing in exposed or covered applications. It cures into a tough, seamless, elastomeric barrier that resists ponding water and extreme weather conditions, making it ideal for rooftops, balconies, planter boxes, retaining walls and wet areas.
Formulated for high tensile strength, crack bridging, and permanent flexibility, Duroproof PUM PRO delivers outstanding adhesion to concrete, screeds, metal, and cement sheeting without the need for reinforcement in most applications. Its fast-curing formulation and Class III rating under AS4858 make it a versatile, reliable solution for both residential and commercial projects.
Available in 15L tins, this solvent-based membrane applies easily by roller, brush, or airless spray.
