THE BLOWOUT PATCH: Fixing All of Those Insulation Holes
Endless. That is how patching all those holes from insulating the walls feels. On the up side, I am learning a new skill….I can now cut and apply a blowout patch. Apparently, a blowout patch is what you use to patch holes that have nothing behind them to screw into.
And , lucky me, I have close to a hundred of these to do. Oh boy, the excitement never ends. Some of the holes are lined up well enough that I can probably cut one big rectangle around them and do a more traditional patch. I’m really hoping for more rather than less of those situations!
So here is what I learned and I have to say it is pretty easy. First get your tools ready. Here’s what you need:
- utility knife
- straight edge
- measuring tape
- drywall saw
- drywall tool (basically a big, flexible putty knife)
- rasp (optional, but very helpful)
- and of course drywall and joint compound
Since most of the holes I have to patch are exactly the same diameter, Brad made a square template so that I could eliminate a lot of measuring. The template we are using is a 5″ square of 1/4″ plywood.
First, I traced the 5″ square onto the wall around one of the holes and I cut the square out of the drywall using the drywall saw.
Second, using the carpenters’ square, I drew a 7″ square on the drywall and cut out the square.
Then, on the back of the drywall I drew a 5″ square in the middles of the drywall piece. Using the straight edge and utility knife I scored the lines marking the 5″ square.I was careful not to cut the drywall all the way through because what you do is just peel the outer edges off of the back of the drywall, leaving just the paper. What I ended up with is a 5″ square of drywall with a one inch perimeter of drywall paper. The perimeter of paper is what is used to attach the patch to the existing wall.
Using the drywall tool and joint compound, I spread some joint compound on the wall around the hole. I then generously buttered the edges of the drywall piece with more joint compound. Then I placed the patch in the whole and smoothed all of the compound using the drywall tool.
I found that if I cut the patch a tiny bit too big, rather than trimming down with the knife and risk cutting the paper, I could slim the edges down with a rasp. Alternatively, I could use the drywall saw and make the hole a little bigger.
Once all the holes are patched, there will be a lot more mudding and sanding to do to get the walls perfectly smooth, before I can paint. And I imagine (and hope) that I will get a lot faster by the time I am done with all the patches!
