Forspec ACTFLEX 929 HV

High Viscosity Polyurethane Membrane

ACTFLEX 929 HV is a high-performance, flexible polyurethane waterproofing membrane designed for internal and external applications. This single-component, moisture-cured membrane forms a tough, seamless barrier that protects surfaces from water ingress, moisture damage, and environmental exposure.
Engineered for durability and flexibility, ACTFLEX 929 HV is ideal for use under tiles and in non-exposed areas such as balconies, planter boxes, and wet areas. Its non-sag formulation makes it easy to apply on both vertical and horizontal surfaces, delivering reliable waterproofing performance across a wide range of construction projects.
