Drywall prep for paint

What happens here

After sanding, the walls will be covered in fine drywall dust. It is critical to remove all this dust before priming or painting, as paint and primer will not adhere properly to dusty surfaces. First, use a shop vacuum with a brush or crevice attachment to thoroughly vacuum all wall surfaces, from top to bottom, including corners and edges. Once vacuumed, fill a bucket with clean water, lightly dampen a drywall sanding sponge, and wipe down all the walls. This step ensures that any remaining dust particles are removed, leaving a clean surface for optimal paint adhesion.

Goal: Remove all dust and debris from the walls

work of it. And remember, if you can feel it, you're going to see it. Step two, vacuum and wipe. Paint and primer does not like to adhere to a wall with dust on it. >> [snorts] >> I have to get myself a bucket of water and a sanding sponge. Take the sanding sponge and just wipe it down. Just get rid of all that dust. Next up, after you got everything cleaned, is to prime it. And you have to prime new drywall after you're done
