Description

SikaBond SBR – styrene butadiene-based waterproof bonding agent, primer and mortar admixture

SikaBond® SBR is a styrene-butadiene co-polymer, which has numerous uses as an admixture, primer, bonding agent and sealer for use in areas subject to humidity, dampness and water contact. Improves water resistance of cement mixtures by forming a reinforcing polymer that increases long term durability and flexibility of the mix on renderings and floor screeds. An admixture for cement and concrete applications, including repair and renovation, surfacing of floors and bonding generally. It contains anti-foam to control the density of cementitious mixes.
