4 Steps to Paint Over Old Interior Paint

When painting over old interior paint, you will need to complete the following steps to ensure optimal results:

1. Clean Each Surface You Wish to Paint

Before applying paint to any surface, it should be thoroughly cleaned. For extremely old paint, you may need to use a chemical degreaser to remove extremely old dirt or grime. Failure to remove these substances from your wall can negatively impact adhesion, leading to a low-quality finish that is full of imperfections.

2. Sand the Surface for Better Paint Adhesion

After you have sufficiently cleaned each surface, it is time to scuff sand them. Sanding each surface allows for better paint adhesion, making it well worth the time and effort. To minimize mess, some professionals utilize dustless sanding methods. If you are unable to use this method, you will need to clean up before you apply any primer or paint.

3. Use Primer if There are Stains or Colour Changes

Primer is a vital yet sometimes overlooked element for painting projects of all sizes. If you are painting over extremely old paint, you will likely need to apply primer first. This is especially true if you are painting over stains or if you will be changing the colour of your walls. Without primer, stains or old colours can show through the new paint, so be sure to take the time to apply it.

4. Choose High-Quality Paint Products

To ensure optimal results for your painting project, it is best to choose high-quality paint products. While you may be tempted to choose cheap brushes, rollers, and paint, this will only decrease the quality of the final result. To put it another way, there is a reason that professionals only use high-quality products for the work they perform.
