If you’re painting a wall with matte paint, it’s important to keep the surface clean and free of dirt, dust, and other debris. Here are some tips to help:

  1. Start by wiping down the surface with a dry cloth or paper towel. This will remove any built-up dirt and dust.
  2. Next, use a vacuum cleaner to suck up all the debris that has built up on the surface. Be careful not to damage the paint or its finish.
  3. Finally, use a hairdryer to dry the surface completely off. This will remove any remaining moisture and make the paint more durable overall.
