Retexture Painted Walls

The walls in my house are textured with a poor texture. The walls are painted with a semi gloss latex. What steps need to be taken to ensure that a skim coat will stick and support a new texture.

They make a primer that you can buy at HD. You pour some in a bucket, mix it with water, and paint it on. It goes on like water. I'd mix it up fairly strong to ensure it does the job. It's a de-glosser. It should get you ready for the new surface.

Good Luck.

If you are sure the semi-gloss is a latex, then you really
don't need to degloss the walls, because regular full-strength
drywall compound will stick to it just fine.

Just be sure the surfaces you are going to skim are free of all
grease, dirt, oil, soap and all cleaning residues (like TSP?).

The regular joint mud I am recommending is the heavier, tougher
version of joint compound. Don't use the lightweight for skim
coat, except maybe the last coat (for ease of sanding). The
full strength mud has a more substantial limestone base and
really goes on nicely, sticks well and provides a good base
for your final topping coat.

If you are one of those who likes hot mud (quick-set compound),
then I would add some plaster bonder into the water before you
add the powder. This gives you some extra "stickability".
