Recently, Rory was called to a circa 1900 home to repair a hole in a plaster wall. The hole was formed when a careless electrician used a sawzall to cut a space for a light switch. The vibration of the saw caused damage, resulting in an approximately 12 inch diameter hole that needed to be stabilized and filled in with new plaster.
After stabilizing the lath and plaster with Plaster Magic® Adhesive, Rory applied the patching plaster. Using Plaster Magic®’s Patching Plaster, which is specially designed to be flexible and bond with existing historic plaster, Rory filled in the hole with a “rough draft” of sorts, also known the “scratch coat”. After letting this layer dry overnight, he was ready to move on to the third and final step: applying the finish coat.
In the video below, Rory shows you how to smooth down the scratch coat in preparation for the final coat. He then uses a simple joint compound as the final coat.
After that final coat dries, you’ll simply give it a light sanding and paint or wallpaper over it.
Voila! Hole fixed.
