9 Steps To Prepare Wall with Primer: DIY Edition


Step 1: Gather Your Supplies

Before you begin, ensure you have all the necessary supplies on hand:

  • Wall primer of your choice
  • Paint rollers and brushes
  • Painter’s tape
  • Drop cloths or plastic sheeting
  • Sandpaper or sanding block
  • Putty knife
  • Tack cloth or microfiber cloth

Step 2: Clear and Protect the Area

Move furniture and decor away from the walls to create an unobstructed workspace. Cover the floor with drop cloths or plastic sheeting to catch any drips or spills. Use painter’s tape to protect trim, baseboards, and outlets from primer splatters.

Step 3: Inspect and Repair

Examine the walls for any imperfections like cracks, holes, or dents. Use a putty knife to fill these areas with spackling compound or patching plaster. Once dry, sand the patched spots until they’re smooth and level with the rest of the wall.

Step 4: Clean the Surface

Dust, dirt, and grease can hinder primer adhesion. Wipe down the walls with a damp cloth to remove any surface contaminants. For stubborn stains, use a mild detergent and water solution. Allow the walls to dry completely before proceeding.

Step 5: Sand the Surface

Lightly sand the entire wall surface with fine-grit sandpaper or a sanding block. This step helps create a slightly roughened surface that improves primer adhesion. After sanding, wipe down the walls with a tack cloth or microfiber cloth to remove any sanding dust.

Step 6: Begin Priming

Stir the primer thoroughly before starting. Using a brush, cut in around the edges of the wall, including corners and along the ceiling and baseboards. This ensures a neat and precise application. For larger areas, use a paint roller to apply the primer in even, overlapping strokes.

Step 7: Apply a Second Coat (if needed)

Once the first coat of primer is dry, assess if a second coat is necessary. Some surfaces might require an additional coat for optimal coverage and adhesion. Allow the first coat to dry completely before applying the second coat.

Step 8: Let the Primer Cure

Give the primer ample time to cure according to the manufacturer’s instructions. This typically takes a few hours to overnight. Curing ensures that the primer forms a strong bond with the wall surface, setting the stage for the paint.

Step 9: Ready for Painting

Congratulations! Your walls are now properly prepared with primer, and you’re ready to move on to the exciting step of painting. With a solid primer foundation, your paint will adhere better, look more vibrant, and last longer.


Properly preparing your walls with primer is a crucial step in achieving a successful DIY paint project. By following this step-by-step guide, you’ll create a smooth, even surface that allows your paint to shine. Remember, a little extra effort in the preparation stage goes a long way in ensuring a professional-looking and durable paint finish.
