The most important thing you can do to keep your flat wall looking as good as new is not to get it dirty. Matte walls don’t have the protective layer that waxed or shellac-painted walls have, so they’re more susceptible to stains and damage from spills. That’s why taking care of your matte walls is important!
If you’ve spilt anything on your matte-painted walls in the past, we recommend using a soft sponge with mild soap and water to get rid of the stain. You should try not to use anything too abrasive or harsh on the wall because this could damage the finish over time.
