Follow the steps given below
for a new construction.
- Clean the surface of the sunken slab of all loose particles, dust, cement laitance etc.
- Moisten the surface with water for half an hour before you are ready to carry out the next step.
- Prepare a slurry consisting of 1 part by weight of Polyalk WP and 1.25 to 1.50 part (by weight) of fresh white or grey ordinary Portland cement. Ideally the mixing should be 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, taking care to prepare as much slurry as can be utilized within 30 minutes.
- Apply two more brush coats of similar slurry at intervals of 4 hours 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 (terrace).
