OptiFlex-20 PU Liquid Waterproofing System

OptiTec Ltd

What is it?

OptiFlex-20 is a fast-curing, pure polyurethane, single-component, liquid waterproofing membrane. Applied with a brush or roller for a seamless and fully bonded membrane and reinforced with 225gsm matting, with OptiFlex-20 there’s no need for mechanical restraint to the roof substrate, making this a versatile and popular choice for many projects.

What can it be used for?

OptiFlex-20 is suitable for both commercial and domestic use and has a low odour formula which is perfect for sensitive sites, such as schools, hospitals, and nursing homes.

OptiFlex-20 also has a high level of flexibility and exceptionally tough characteristics, offering protection for the most demanding and complicated projects, with the ability to follow the silhouette of roofs with even the most intricate designs.
