Description
Sika Bond SBR+ is a multi-purpose styrene-butadiene rubber (SBR) latex bonding agent and admixture designed to improve the performance of cement-based mixes. Supplied in a 5 litre container, it is commonly used to enhance adhesion, flexibility, and water resistance in mortars, screeds, and renders.
When used as a bonding agent, SBR+ creates a strong bond between new and existing concrete or masonry surfaces. When added to cement mixes, it improves durability and resistance to moisture, making it suitable for demanding internal and external applications.
