Saved the wall!
Our wall isn't perfect, but it looks a lot better than when it was covered in 70's wood paneling. When I removed the paneling I found out why the previous owner hung it it the first place. There was a huge area of exposed drywall paper and over 40 1/2" drilled holes in the wall. My drywall guy was busy and I had to fix the wall fast before my vacation ended. We are complete armatures at this type of project, but I have other walls in the house that are warped from previous similar repairs. I watched a YouTube video on drywall repair. I did all the prep work and repairs and my husband did the spray texture with a Harbor Freight texture gun. I covered the big bare areas of the drywall paper with one coat of Gardz. I just brushed it on with a paint brush. It sealed all the layers of paper fuzz and dried to a rock hard surface. This stuff really works. My only mistake was not scraping off all the glue before texturing. This product saved the wall in my opinion.
