Patching Insulation Holes With Drywall Compound

Video Transcript

"So the next step to insulating an existing wall is to patch the hole that has now been filled with expandable insulation with drywall compound and you will want to apply this with a putty knife. You want something fairly wide. You want it to be at 1 ½ to 2 times the width of the hole because you need to press firmly as you are applying the drywall compound and you don’t want to puncture the hole that you just spent all this time filling and trying to firm up. So this is a good blade. It is a 6 inch blade so it will do well to cover that 3 inch diameter hole. So you will just apply a pretty large chunk over the hole. You might need to go back and get a couple of scoops. Clean off your blade pretty good. With the edge of your blade hold the mound kind of loosely over the hole and make sure it is really covered. Once it is fully covered, if there is any major chunks you kind of scrape off the excess and then you want to apply pretty firm pressure starting away from the hole so you can almost hear it scraping against the wall and then right over the hole kind of loosen pressure and then tighten up again as you are heading out of the hole. You want it to kind of taper to no compound at all. Just go around the hole and make sure this side is tapered. This little area; I pushed it a little too hard here. I’m going to add just a little bit more. You don’t want the texture of the insulation foam coming through. Once this dries, it takes about 24 hours to dry. They will sand it smooth and paint it. "
