Painting Concrete walls.
You will need
- Masonry Neutralizer
- Acrylic white flat paint for primer
- Calsomine
- Acrylic semi-gloss paint for top coat
- #80 Sand paper
For newly finished concrete wall apply a concrete masonry neutralizer and let it stand for 24 hours. This process will remove all acids in the cement, sand and water mixture.
Approximately a gallon of paint covers 20-25sqm of wall for primer and 15-20sqm for top coat.
1. Apply first coat of primer (flat acrylic paint, water based).
2. Add small amount of acrylic paint and calsomine to create a putty. You need a spatula and scraper. Apply it over the wall surface and level using spatula and scraper. Let it dry.
3. Sand surface until you achieve adequate level.
4. Apply 2nd coat of primer and let it dry.
5. Then apply top coat, semi-gloss paint (add tinting color on your desired shade)
Reminder- when mixing paint, you should ensure that you are not over mxing it. Stirring should not be to fast or too slow. If paint mixture is bubbly, you will notice bubbles on the surface and it will turn out rough. Paint bubbles or peeling is an evidence of a poorly neutralized wall.
