Use painter’s or masking tape to mark off the areas you are going to be cutting and draw your cut line on the tape. The tape will help keep some of the crumbling plaster from falling out in the middle of your cut if there is any and it helps you see what you are cutting. Step #2 Make Your Cut
Using either the angle grinder or multi-tool cut along your line. Make sure to finish the cuts all the way to the end so that all the lines connect. Be sure to cut all the way through the wood lath behind. Step #3 Remove the Patch
If you’ve cut all the way through the lath, the patch should fall right out as you make your last cut. Take this time to clean up anything necessary keeping in mind that the hole doesn’t have to be perfect since it will likely be covered with a switch plate or some other escutcheon for the item you are installing. Step #4 Cleanup
Vacuum up any remaining dust and wipe the wall down with a wet cloth to get the remaining plaster dust off.
