want to ask, i have got a new house.. just completed the renovation work.
The renovation work involve hacking of wall to conceal wiring in brick wall where there is a lot of dusts on the surface of the wall (and everywhere else).
Does the wall need to be somehow clean before painting is applied?
Any sealer required for these wall with already quite good paint?
need to sand off the existing paint?
or just applied the new paint to the existing paint.
Let me know if there is anything else to take note.
Thanks.
1. Use a broom or some cloth to wipe away loose dust.
2. Use scrapper to remove loose paint.
3. Sealer for places with bare wall( places where you hack and can see bare concrete)
4. Paint with desired color paint.
