SKU

Bostik Cementone SBR Waterproofing & Strengthening Admix 25L – 30812495


The Bostik Cementone SBR Waterproofing & Strengthening Admix 5L is a high-performance, latex-based admixture designed to enhance the durability and versatility of cementitious mixes. Engineered with styrene butadiene rubber (SBR), this multi-purpose additive improves bonding, waterproofing, and overall strength in both internal and external building applications.

Product Features/Specifications:  

This 5-litre container of white liquid SBR admixture is a solvent-free, low-odour formulation suitable for a wide range of building projects. Designed for use with cement mortars, screeds, and renders, it enhances both chemical and water resistance while reducing shrinkage and cracking.

Detailed Product Benefits: 

Bostik Cementone SBR dramatically improves adhesion to substrates, making it ideal for challenging surfaces like concrete, brick, and masonry. It enhances flexibility, making your mixes more resistant to cracking under thermal or structural stress. Additionally, the waterproofing properties make it a top choice for damp-prone environments such as basements, bathrooms, and external walls. It also allows for thinner screeds without compromising on strength, improving cost efficiency and ease of application.

Applications and Versatility:

Perfect for bonding slurries, floor screeds, patch repairs, and tanking systems, Bostik Cementone SBR is suitable for both DIY enthusiasts and professional contractors. Its versatility extends to waterproof rendering, tile fixing, and as a primer for surfaces that require improved adhesion and moisture resistance. Whether you’re working on new builds, renovations, or structural repairs, this admixture delivers consistent, long-lasting results.
