EVERBUILD® 503 Premium SBR Bond is a water resistant bonding agent and admixture 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. It contains anti-foam to control the density of cementitious mixes. Greatly improved adhesion to a wide range of substrates including dense concrete, steel, tiles etc. Mixes may be applied in thinner sections. Excellent resistance to water and water vapour. Advantages Greatly improved adhesion to a wide range of substrates including dense concrete, steel, tiles etc. Mixes may be applied in thinner sections. Excellent resistance to water and water vapour. A high level of resistance to salt permeation. Much improved toughness and flexibility. Reduced surface dusting of concrete. Greatly improved resistance to many chemicals- ideal for use in dairy parlours etc. Reduced water: cement ratio for equivalent workability. Improved frost resistance. EVERBUILD® 503 Premium SBR Bond is also freeze thaw stable.
