How to Wet Sponge Joint Compound


Following is a brief description of the process. For a detailed, step-by-step description, see Drywall Wet Sanding in 6 Steps.

1.Start with joint compound that is not completely dry. However the compound should be dry enough that it won't immediately smear off when you touch it. Drywall joint compound a few hours old should be right.

2.Soak sponge in bucket, then squeeze out.

3.Start with light, circular motions. Remember, let the water do the work more than pressure from your hand. Right now, you're just concentrating on the high ridges and the spiky portions.

4.When it gets too difficult or the smears are too thick, rinse out and squeeze sponge in bucket. Sponge should be wetter than on the first pass.

5.On this second pass, since you've already taken down the high ridges, you can concentrate on lowering the joint compound "bump."

6.After two passes, you're done. Any more wet sponging will get the drywall paper too wet. If two passes aren't sufficient, you may need to dry sand the joint compound.

I have a large entertainment center that would cover half of it up while the rest was just a big blank 21/2 foot wide opening to the ceiling. Also they had covered up the crappy edges with a two or three inch protruding decorative frame, so it would have pushed the entertainment center out from the wall. I don't really know what else to do with it, it's in the middle of the only wall where the TV can go.

Pull out the damn frame and build one in place so it fits right, it ain't rocket science, I know.

You are over thinking a simple project. This isnt rocket surgery. The framing doesnt need to be perfect. You can have no backing at the edge for drywall up to 6 or 8 inches and you will be fine. Throw up the drywall the best you can and as long as you are with 1 inch of your goal use mud to fill the gaps, tape it and start the finishing process as explained above.
