Our Liquid Applied Membrane Technologies

One-component polyurethane based liquid applied membranes

One-component polyurethane based liquid applied membranes and roof coatings were invented in the 1960s and represent an indispensable technology in today’s roofing industry. Due to their high mechanical properties and flexibility, particularly at lower temperatures, as well their capability to cure under a wide range of conditions, polyurethane based liquid applied membranes can also be used in climatically challenging environments.

Sika Liquid Project
Two-component polyurethane/polyurea based liquid applied membranes

The demand for two-component polyurethane/polyurea (PU/PUA) based liquid applied membranes has risen in the last decade. The fast and efficient application method by two-component spray machines makes it particularly suitable for large surface application and industrial application. Once the product is mixed in front of the application nozzle and applied to the surface it cures within seconds, allowing a fast over coating or early pedestrian traffic.

Sika has adapted the two-component PU/PUA hybrid technology to cold applications and hand-applied systems, making it now possible to do installations where hot spray is not efficient, while maintaining the same performance characteristics.
