Reliable Waterproofing for Mortar and Render
The Cementone Integral Waterproofing Liquid – 5L by Bostik is a high-quality liquid additive formulated to deliver long-term water protection for mortar, non-structural concrete, and render.

Whether you're working on external renderings, basement walls, pointing, swimming pools, or tank linings, this waterproofing solution is designed to reduce water ingress and enhance the longevity of your project.
Its advanced formula contains an alkaline soap of mixed fatty acids, which reacts chemically with cement to form hydrophobic salts—creating a powerful barrier against water penetration.
