The surface to be painted must be dry and clean, free of dust, dirt, and oil. Small holes or fine cracks should be repaired before being painted. Protect parts that don’t want to be painted with duct tape, paper or adhesive tape. Barriers between walls and floors, windows and frames, windows usually must be covered so as not to be exposed to paint stains. When finished, immediately unplug the adhesive tape before the wall paint dries so that the paint is not removed.

For surface preparation, there are two things to note from this first step.
a. New surface:
For perfect results, let the new wall dry completely.
b. Old surface:
If the adhesion and condition of the old paint are still good, the surface of the wall can be directly painted. For the best results, scrape the chipped paint thoroughly and sand the surface evenly.
Before starting with wall paint, use a base paint containing acrylic emulsion paint that has resistance to alkaline salts and efflorescence.
