If the building is already completed:

1. Scrape off all loose plaster or screeding

Don’t paint over damaged surfaces—it will peel again.

2. Allow the wall to dry completely

This may take days or weeks depending on moisture level.

3. Apply a Waterproof Chemical Slurry

Use:

SikaTop Seal

Dr. Fixit Waterseal

Fosroc Brushbond

This blocks moisture movement.

4. Re-plaster With Waterproof Additive in the Cement

Plaster + waterproof additive = durable wall.

5. Use High-Quality Exterior/Interior Paint (Acrylic-Based)

Cheap paints peel faster.

Enjoy your house... You deserve happiness! 

The End!
