2torial #0658: Learn2 Patch a Hole (Continued) Method 2: Gypsum Board Wall Mud and tape Here's where you create a smooth surface to paint over later. There are two types of tape on the market: one kind self-adheres when wet while the other kind is perforated, and is pressed into the compound. For beginners, the second kind is generally a bit easier to work with, and that's what we'll use here. Take a small amount of joint compound (mud), and thin it slightly with water, not too much, perhaps two tablespoons of water for a cup's worth of mud. Put the mud on the old salad plate.   Take the wallboard knife, and pick up some mud. Draw it over the seams between the patch and the wall, as well as the depressions where the screw heads are sunk. You are not trying for a flush surface, but one that bulges where a gap has been filled.   Repeat as many times as necessary to fill all the gaps and depressions. Again, don't try to get a perfect surface at this point. You'll want to lay the mud on a bit thick (perhaps 1/8" ) and spread it on either side of the seams as you'll be embedding the tape in the mud. Cut four pieces of tape so that they will each cover a seam, but not overlap. Take the wallboard knife, and press the tape into the wet mud, starting from one end and working towards the other. Position each piece of tape so that it meets the edge of another.   Take a small amount of mud on the knife, and run it over the tape. You want the tape covered with a thin layer, and the edges of the tape concealed in the mud.   Wait a few hours for the mud to dry, then sand the surface gently with the block and sandpaper.   Lay another thin coat of mud over the taped areas with the knife, wait for a day and sand it again. Make an effort this time to achieve a smooth, even surface before priming and painting.   Prime and paint the area to match the rest of the wall   -end- Learn More! or All steps at once (printable version)
