Drywall "hot patch"

The master bedroom had one weeny little wall sconce to light the whole room, so I had wiring run for a ceiling light and one of those crazy modern inventions, a light switch.

(Many rooms in the house didn't have light switches -- they were never installed after the switch from gas lighting to electric. See page 4 of this handout for the history of lighting from Rejuvenation.)
To install wiring, the electrician cut two four-inch holes in the plaster so he could fish wire through the wall.

Mike the roofer saw this and asked if I knew how to do a "hot patch." He started describing it, and I thought, yeah, I do! I just didn't know what it was called. I learned it at drywall class.

This method works for many random holes in drywall or plaster, such as a doorknob puncture or, if things are a little crazy at your place, a fist punch.

1. For an irregular wall hole, cut the edges into a square for easier installation.

2. Cut a piece of drywall to match the shape of the hole, but do NOT cut through the bottom layer of paper. Leave two or three inches of paper at the edge.This paper becomes built-in "tape" for your repair. (see below. this is hard to describe)

3. Coat the paper with joint compound. For a ceiling patch, you might want to coat the edge of the drywall, too, as in the above photo (like frosting a layer cake)

4. Install in hole. Smooth paper and cover with a coat of joint compound. No screws needed!

5. Let dry. Sand. Apply another coat of joint compound and repeat until satisfied.

How cool is that.

Very cool! I never thought of leaving the paper on the "out" side before. That owuld sure help make a great patch. Thanks for the tip!
