How to skim coat to get rid of textured walls.

Step 2: Roll on the mud

Spread a layer of slightly thinned all-purpose joint compound on the walls with a heavy-nap roller. Work in small sections so you can smooth out the joint compound before it starts to dry.

Mix all-purpose joint compound to about the same consistency as mud you’d use for bedding tape (the consistency of mayonnaise, or just thin enough to roll on the wall). You’ll get shrinkage if you mix it too wet. Don’t worry if you get cracking on the first coat; just mix the next coat a little thicker by spooning in some fresh mud from another bucket.

Use a 1/2-in.-nap roller to roll mud on an area about 4 ft. square (Photo 2). Try to keep it as even as you can so the squeegee work will go better for you.
