Waterproof polymer bonding aid and mortar additive.
A pure polymer emulsion, designed to improve the mechanical and waterproofing properties of sand/ cement based screeds, mortars and renders. The addition of Cempatch SBR has a strong plasticizing effect, thereby allowing a reduction in the water/ cement ratio, further improving the flexural, tensile and compressive strength and enabling screeds to be applied down to 10 mm and renders down to 6 mm. Its addition will also significantly increase resistance to chemical attack, abrasion and freeze-thaw cycling.
