My work includes patching holes in drywall from time to time. And if the holes are in textured walls, either orange-peel or knock-down texture, I’ve got to set up my commercial sprayer to re-texture the patch. Between setup and cleanup, that’s a lot of work for a small job. As shown in the drawings, I’ve found a better way.
I begin a patch by applying mesh tape over the hole (l).Then I cover the mesh with all-purpose drywall compound (don’t use setting-type compound) applied with a 4-in, taping knife. This process patches the hole but also clogs the crevices that create the texture (2). Once the drywall compound has dried, I sand smooth the center of the patch. Then I feather the edges of the patch with an old toothbrush dipped in warm water and a dry cloth. I work my way around the patch (3), leaving a tapered surface that makes a gradual transition to the smoothly sanded center of the patch.
To finish, I prepare a mixture of water and all-purpose compound thin enough to produce a splatter. Next I suck some of the mix into a turkey baster and practice splattering on a piece of scrap until I get the effect I’m looking for. This step is important: Trial and error is the key to making this technique work. When I’ve got the right consistency, I’m ready to texture the patch (4).
