Paint Preparation for Painting Over Dark Walls

Thinking of painting a dark wall with a light white or pastel colour? Unfortunately, this can be difficult. Dark wall paint has a tendency to show through lighter paint, and this can alter the tone and hue of your new colour. Patience and proper paint preparation will ensure the lighter paint shows up true to colour.
Cleaning

Sugar soap, or even detergent and warm water should do the trick. Give your walls ample time to dry before you begin painting. Paint will not adhere to a damp surface.
Wall Preparation
If you’re after a perfect, professional finish, you must fill in any wall imperfections, and sand over peeling, uneven paint.
- You can fill in small dints and holes with a drywall mix or filler mixed with water and applied with a small, flat-edged tool. Once the drywall has dried, use a fine-grain sandpaper to smooth out the surface.
- To remove peeling or uneven paint, use medium-grain sandpaper and sand the area until smooth. Run your fingers over the area to ensure it is flat. Finish off with fine-grain sandpaper.
Primer
When painting over dark walls with a lighter colour, using a primer is essential. A white primer will conceal the colour underneath, allowing your new paint to dry true to colour.
Purchase a white primer, or a block-out primer. Use a roller to paint the wall. Roll out in big ‘M’ and ‘W’ shapes to ensure even coverage, and to avoid roller lines. Allow the primer to dry completely.
If you can still see the dark colour through the primer once it has dried, paint a second coat. Once the final coat of primer has dried, you’re ready to get painting.
