Saint Gobain Weberend Aid Key Coat For Rendering – 25kg

Applied seamlessly using a hawk or trowel before finishing with a stipple roller, Saint Gobain’s Weberend Aid is a polymer-modified sand and cement stipple render. It is best used as a preparatory key coat prior to the application of render.

Weberend Aid features a bonding agent that can be added to clean water on site and resists external water penetration, improving weather resistance of rendering systems and making it the perfect pre-treatment for render that needs to withstand critical exposure conditions.
