How to Prepare an Internal Wall for Painting?

Posted By

Internal wall painting is one of the most popular home improvement projects. A fresh coat of paint can make a lot of difference to the look and feel of your interiors. 

Proper wall preparation is critical to achieving desired results. To help you out, we have put together a step-by-step guide to prep your internal walls before painting. 

Clean Your Walls 

Washing your walls will remove dust, stains, cobwebs, grime, and other contaminants that can prevent the paint from adhering. Wash the walls with a homemade cleaning solution of approximately three teaspoons of laundry detergent to one gallon of water. 

If you have wallpaper on the walls, remove it and clean the walls thoroughly. If mold is in your walls, apply an anti-mold solution to the affected area. After washing your walls, give them a quick rinse, and allow them to dry. 

Remove Old Paint 

Using a paint scraper and sandpaper, remove cracked or flaking paint to smooth the surface. For large areas, use an electric sander. 

Repair Damaged Areas 

Repairing the damaged areas will prevent the recurrence of problems. To achieve your desired results:

  1. Find imperfections and address them before painting and priming your walls
  2. Remove the old plaster
  3. Fill the gaps around your windows and doors with a high-quality sealant

Some imperfections are easily visible, while others aren’t. Use a utility light to spot such flaws. Mark any flaws you notice. Use sandpaper to smooth these imperfections away. 

Use Lining Paper 

In many cases, using a lining paper won’t do much good. If, however, your walls have lots of fine cracks or large damaged areas, a lining paper can help create a smooth base for your paint. 

Priming 

A primer is a preparatory coating applied on surfaces to prepare them for painting. There are several benefits of priming. Priming seals pores, covers unsightly imperfections and marks, helps block out stains and odors, and extends the life of your paint. 

After preparing your walls:

  1. Cover the surfaces you don’t plan to paint.
  2. Dampen your paintbrush or paint roller.
  3. Outline your walls with a 2-3 inch band around the edges.
  4. Apply the primer at all points where the walls, molding, and ceilings meet.
  5. Brush the primer on areas that need special attention.
  6. Dip your roller into the primer and apply it in 3X3-foot sections. 

After the primer dries, lightly sand away bumps.
