Crusty, Flaky Stuff on Woodwork

March 2, 2018


You’re looking at a section of crown molding. See that flakey stuff? That is the enamel paint on cracking and chipping off the woodwork. Why? When the original wallpaper was installed, some paste got on the crown molding. This is normal.

But in this case, the paperhanger didn’t wipe off all the residue (this can be hard to do, because it’s really hard to see). Over time, that paste residue ate into the paint and caused it to crackle and chip off the wood.

This can be avoided by making sure that all paste residue is completely wiped off any painted surfaces. I like to use a thin blue plastic tape on the top edge of wallpaper, which keeps paste from coming in contact with the crown molding or ceiling.

Crinkly Paint Caused by Paste Residue

Hard to discern, but the red / brown at the top of the photo is wallpaper, on the vertical side of a soffit around the top of a dining room. The greenish area is the bottom of the soffit.

The craggly looking stuff at the junction is crackling paint. Why is this paint getting crackly and crumbly?

Wallpaper paste will cause paint to crackle. The original installer must have left a teensy bit of adhesive on the wall (which is easy to do), and, over time, a reaction occurred, and a very small strip of paint began to crack and flake.

This was only about 2″ long, and 1/16″ wide, and 10′ up in the air, so, not anything anyone is really going to notice. And, over a decade and a half, nobody ever did. Only me, when it was time to strip off the old paper.

I do find these little things interesting, though, because they help me be aware of things that can happen, and help me to take measures to prevent them when I am installing a wallpaper job.
