Painting Over Mud Swirls on the Walls

Mud, also known as drywall joint compound, masks nails, drywall tape and imperfections on any surface containing sheetrock. The substance is also used to make swirls on sheetrock walls. You can paint over mud swirls, using latex or other types of paint. You can even leave the swirls in place or sand them out with sandpaper. You'll need to properly prepare the surface containing mud swirls, so dust and debris won't fade through the new coat of paint.

Things You'll Need

  • Bucket
  • Borax
  • Ammonia
  • Warm water
  • 3 old socks
  • Latex gloves
  • Package of 220-grit sandpaper (optional)
  • Soft cloth or rag
  • Paint tray
  • Latex or other paint
  • Paint roller
  • Paintbrush

Instructions

  1. Wall Preparation

    • 1

      Move any furniture, carpets and other items from the room containing the mud-swirled walls you want to paint.

    • 2

      Mix 2 ounces of Borax, 1 teaspoon of ammonia and 2 quarts of warm water in a bucket. Stir the soap mixture with an old sock. Wear latex gloves to keep your hands dry.

    • 3

      Wring out excess soap mixture and scrub the wall you want to paint from the bottom up, using the mixture-soaked sock. Scrubbing from bottom up keeps dirt and debris from soiling clean areas. Use a clean, old sock when the one you are using becomes too soiled. An old sock won't leave strings on your mud swirl walls.

    • 4

      Continue scrubbing one wall at a time until all the walls are clean. Let the walls air dry thoroughly before moving on to the next section.

    Painting

    • 5

      Sand mud-swirled walls with a piece of 220-grit sandpaper, if you don’t want the swirls to show through the new layer of paint. Otherwise, skip to step 3. Use a new piece of sandpaper when old pieces become smooth and soiled.

    • 6

      Continue sanding until the walls are completely smooth. Wipe the walls thoroughly with a soft cloth or rag to remove any sanding dust.

    • 7

      Fill a paint tray with latex or other type of paint and apply the paint to a roller. Start rolling the paint on one wall, using a "V" formation. Roll the paint over the mud swirls so the letter V is painted on the wall. Paint a straight line in the middle of the V to complete the formation. This formation provides paint evenly to all areas of the mud swirls.

      Use a paintbrush to paint areas and trim that you can't reach with the roller. Let the walls air dry and repeat steps 3 and 4 to apply a second coat of paint to the walls. Allow four to six hours for the paint to completely dry.
