Clean the surface thoroughly and remove dust, oil, grease, loose particles, and laitance. Repair cracks, honeycombs, and damaged areas before applying the coating. Pre-wet the surface with clean water so that it is damp but free from standing water. Mix the liquid and powder components thoroughly to obtain a smooth, lump-free slurry. Apply the first coat using a brush in a uniform layer over the prepared surface. Allow the first coat to dry before applying the second coat in a cross direction. Ensure complete and even coverage for effective waterproofing. Protect the applied coating from rain, direct sunlight, and mechanical damage during curing.
