PU Gel Membrane

Waterproofing Elastomeric PU Membrane

PU Gel Membrane is a tough, UV stable, flexible liquid applied waterproof facade coating with high solar reflectance providing excellent heat insulation and energy efficiency. It can be applied at a DFT of 0.3 mm as an aesthetically attractive textured or semi-smooth finish and is available in a range of standard colours.

Features

Flexible: accommodates normal building movement. Reflects the intense solar heat with an Solar Reflectance Index (SRI) of 103. Provides excellent UV resistance and long-term protection from elements of nature.
Water-based: safe to use and low odour. Breathable. Cost-effective, with longterm savings and short payback period. Naturally fungi retardant.
Decorative: can be applied in different textures.

Application

Substrate Preparation
Surface must be clean, sound and properly cured. Remove all loose materials mechanically, preferably with a wire brush. Iron and steel surfaces should be free of rust.
