Step 4Prep the surfaces
Preparing your surface well is what makes a quality job that lasts. If your wall is in good shape all you will need to do is clean it. Wash it down with a rag and cleaner of your choice.
However most walls are not in good shape, often meaning your prep will take longer than the painting. If there are holes or cracks they should be repaired, but that's another Instructable.
If there are any places where the paint is peeling, scrape all loose paint off, then sand to smooth the edges. Remember, the difference between the bare wall and the old paint will show up as lines if you don't . Also sand any places where there are raised surfaces, such as spackle, crayon , tape residue etc.
After sanding, use your tack cloth to wipe down the surface. Then wash all surfaces, preferably with the tri-sodium phosphate.
