During the move, the movers knocked down the one in our master bedroom. I finally got tired of looking at the damage and decided to fix it.
The first step was to get the molding back on the corner. There was a metal piece there, so I used liquid nails.
I wiped down the corner and the molding with a wet cloth, both to knock away anything that was loose and to help the liquid nails adhere (it was suggested on the package).
Then I put a few blobs down the center of it along the length. Surprisingly, liquid nails was not liquid...it was more gel-like. Blobish.
Then I stuck the molding back up. I didn't have to measure or anything because there were chunks of plaster that came off with it, so I put it back up like a puzzle piece and leaned a small cabinet up against it to hold it into place until it set (about 2 hours...which was probably overkill)
I let it set for a few days. Not just to let it set, but because I got hurt and couldn't finish immediately. Then it was time to fix the surrounding plaster.
Most of the big spots took 2 coats to fill them in. I used a spackling spatula and scooped it in. Once it dried, I taped off the molding so I wouldnt get too much spackling on it and I filled in the rest. It is better to overfill it than underfill.
Because once it dries you can take a small piece of fine grit sandpaper and sand down the excess.
It's a little messy:
Then the last step was to paint the newly fixed wall. More of that to come!
