Surface area to be treated should be solid and cleaned thoroughly. Dust, dirt, grease and all impurities should be removed. Mix 4 litres of CMI PROOFCOAT 087 PART B with 6 litres of water into a 20 litres empty pail. Then add CMI PROOFCOAT 087 PART A into the diluted PART B. Mixing can be done manually or with any suitable type of electric mixer until a thick slurry paste is obtained. Apply by brushing/ trowel onto concrete surface. Two coats are recommended. The second coat can be applied 4 – 8 hours after the first coat.
