Sika 507 Rendagrip Bonding Agent 10 litre

Rendagrip is an extra grip render bonding agent that contains a fine aggregate to provide an improved key before applying render on external surfaces e.g. concrete, lightweight blockwork, brick etc. The fine aggregates are suspended in a unique waterproof polymer to ensure easy application and an even spread of aggregate avoiding any weak spots in the key coat and preventing the aggregate particles coming loose during application.
