How to Fix Paint That Is Too Thick on Walls

You may have painted a wall and noticed that the paint has gone on too thick. This can be an unattractive flaw, but you don’t have to spend hours trying to sand out the imperfections. Instead, remove the painter’s tape and sand all mistakes down to a flat surface. Then, apply a thin coat of paint. Don’t skip this step!

Repair surfaces before painting

Minor flaws in the own surface of the walls are often hard to notice when the afternoon sun hits them. To avoid the possibility of missing spots:

Shut off the lights and close the curtains before starting to paint.

Place a trouble light next to the wall.
Gently move it along the surface to identify any flaws. If you find a blemish, tape it off.

A pencil will bleed through paint and will not be as effective as tape.

If you do notice any damage to the wall’s surface, repair it first. A clean wall will enable the paint to adhere better. Remove any raised sections or nicks. Apply spackling compound or patch it with sandpaper. Afterward, clean the surface with the damp cloth and allow it to dry. Wait at least one day for the patch to dry.

Remove painter’s tape.

When you remove painter’s tape to fix the paint that has become too thick on your walls, be careful not to tear it off the wall. You do not want to get paint on the tape, so you should carefully pull the tape off at an angle.

If the tape is stuck to the wall, you can slice it off with a razor blade. To remove the painter’s tape, you must cut through the dried layer of paint. Don’t cut the paint too hard, as this can cause more damage.

To prevent this problem, you must clean the area before applying the tape. If there is grease or any other greasy residue, you may need to remove more paint.

The surface should also be arid before you start applying painter’s tape. If the tape has not been appropriately applied, use a painter’s tape applicator to speed up the process. When painting interiors, begin at the baseboards and ceiling line. Use stretches of tape no longer than three feet long. Angled tape is also essential for corners.

Sand all mistakes down to a flat surface

When fixing too thick paint on your walls, you can start by wet sanding the entire surface. You may need to remove the top layer of paint first before beginning the sanding process. Next, use fine-grit sandpaper to sand the surface. Once you’ve completed this step, you can proceed with the next step.

Using a sanding sponge will remove stains and lint that may have transferred from the paint roller. You can use an angled sanding sponge to sand surfaces flat in tight corners. The angled sponge is available on Amazon. Using it will make the job easier. This sanding sponge will also remove lint from the walls.

Apply a thin coat of paint

There are several ways to fix the paint too thick on walls:

Make sure the surface is clean and free from any moisture. If the wall has a thick layer of dirt and grime, a few coats of paint may not be enough.
The paint was not properly primed or applied with uneven pressure.
The paint was not allowed enough time to dry, which could have led to uneven coverage or a peeling look.

To avoid this problem, apply a thin coat of new paint. This will reduce the paint’s drying time and prevent dripping and streaking. While some brands recommend applying only one coat of paint, two thin coats are best. This will give your wall a better finish and prevent dripping and streaking. Moreover, paints with higher viscosity will dry more slowly, while those with lower viscosity will dry more quickly.
