Improve render adhesion on challenging backgrounds with Everbuild Feb Rendagrip 10 Litre. Formulated to create a strong mechanical key, this ready-to-use bonding agent prepares smooth and difficult surfaces before the application of render, helping achieve a secure and reliable finish. Rendagrip contains a fine aggregate that produces a textured surface once applied, giving subsequent render coats a better surface to bond to. This makes it particularly useful where the existing substrate may not provide sufficient natural grip for direct rendering. Easy to apply, the pre-mixed formula removes the need for on-site preparation and helps provide consistent coverage across the substrate. Its distinctive finish also makes it easier to identify treated areas during application, supporting efficient preparation before rendering begins.
