ACTFLEX 929 SL -
self levelling polyurethane
Class III high-performance polyurethane waterproofing membrane
ACTFLEX 929 SL is a high-performance, Class III self-levelling polyurethane waterproofing membrane designed for internal and external under-tile applications, including non-exposed wet areas. This advanced membrane provides a tough, highly flexible, and root-resistant waterproof barrier. As a single-component system, ACTFLEX 929 SL cures upon exposure to atmospheric moisture, forming a durable elastomeric membrane. Its self-levelling formula ensures a smooth, seamless, and flat finish, making it ideal for applications requiring an even surface across both horizontal and vertical areas.
