Apply the Plaster: Apply a second layer of plaster (brown coat) about 6-8 mm thick over the scratch coat. Level and smooth the surface utilizing a plastering trowel. While the plaster is still moist, scratch it with a comb scratcher to create a tough surface for the following coat to adhere to.
5. Applying the Finish Coat (Skim Coat):
Dampen the Brown Coat: Dampen the brown coat with water.
Apply the Plaster: Apply a skinny layer of plaster (skim coat) about 2-3 mm thick over the brown coat. Work rapidly and smoothly to realize an even surface.
Trowel and Polish: Use a metal trowel to clean and polish the floor. Keep the trowel slightly damp to realize a clean end.
6. Curing and Finishing:
Curing: Allow the plaster to dry slowly and naturally. Prevent fast drying by masking the plastered floor with damp cloths or spraying it with water intermittently for a quantity of days.
