Cement Reinforcement Emulsion CA-661 is an acrylic emulsion copolymer specially designed to overcome the inherent weakness of cement. It improves adhesion, impact strength, flexural strength, and thin section fragility of cement. It is suitable for use in new construction as well as restoration of old constructions.
Cement Reinforcement Emulsion CA-661 has the following benefits:
For internal and external use
Excellent water and abrasion resistance
Unequalled bond strength to a wide variety of substrates such as old cement, brickworks, wood, and metal
Excellent surface finishing
Environmentally friendly; water-based without solvent pollution and odor
Over 3 hours work time after mixing CA-661 with cement
Excellent workability

Method of Use
Prepare a good, clean surface at all times. Remove all loose, disintegrated material, dirt, grease, oil, and efflorescence. Substrate must be structurally sound. Prepare the solid components (100 parts cement and 300 parts sand) and the liquid components (15 parts Cement Reinforcement Emulsion CA-661 and 45 parts water). A mortar is then prepared by thoroughly mixing the solid and the liquid components. The ratio between solid and liquid components can be changed due to the size of granules and water content of sand.
