Air Bubbles from Latex Paint

June 13, 2018

The walls had a light texture covered with latex paint, so I skim floated over the walls to smooth them. When the wet smoothing compound got onto the wall, the latex paint absorbed moisture, expanded, and created these bubbles. It’s called “off gassing.”

After the mud dried and was sanded, most of the bubbles disappeared, but some rings were still visible. When I primed with Gardz, a water-borne penetrating sealer, many of the bubbles raised their heads again.

I will have to see if they dry flat over night, or if I will have to use my putty knife to knock them off in the morning. I don’t want bumps showing under the new wallpaper!
