Prepare a slurry using 1 part by weight of Polyflex WP and 1 fresh white or grey ordinary Portland cement. Use a mix by weight of 1:1 for the first coat and 1:1.5 for subsequent coats. The mixing is best done using a low- speed stirrer, but continuous hand-mixing to a lump-free consistency is also adequate. Apply the slurry by brush to the damp surface. Prepare only as much slurry as can be used within 30 minutes. Keep the mix continuously stirred. Apply by brush two more coats of similar slurry at 24 hour intervals and allow to set for 48 hours. Cure the coating for 7 days by sprinkling water thrice a day on the vertical surface (external walls) and by moist gunny bags on the horizontal surface.
