How to Prepare the Wall for the Primer Paint

It's important to prime a wall before painting it, because drywall has a porous surface that will soak up the paint and create uneven color. In order to make sure the primer keeps paint color smooth and crisp, it's important to take the time to prepare the wall for the primer paint. Preparation can be time consuming, but it is the most important part of painting a wall.

3/8-inch roller
Painting pan
Primer
Pail
TSP
Sander with fine-grain sandpaper
Vacuum

Instructions

- 1
  Remove all the covers from the light switches and electrical outlets on the wall that you'd like to prime. Usually dust accumulates behind the covers, so it's a good idea to clean around the outlets and light switches as well with a fresh rag and warm water.
- 2
  Feel every surface of the wall to see if there are any bumps or divots.
- 3
  Fix any area that requires patchwork. Then sand the patchwork areas to make sure they're smooth.
- 4
  Brush and vacuum away all the dust created from sanding.
- 5
  Clean the walls with a cleaning solution to remove any dust particles missed during the vacuuming. TSP (trisodium phosphate) and water is a good cleaning solution choice since it doesn't require rinsing and can also remove scuffs.
- 6
  Allow to dry before applying the primer.
