Getting Smoothing Compound to Dry

September 11, 2018

Textured walls have to be smoothed before the new wallpaper can go up.

Getting smoothing compound (drywall joint compound) to dry takes – dry air, moving air, air-conditioned air, heat …. and a lot of time. Today’s job had particularly thick textured walls, which would take a long time to dry.

So I hastened things up with a few accessories. Here you see one box fan on the floor aimed at a wall, another box fan on the ladder aimed higher on a wall, a very strong black floor fan shooting dry air into the room, and a space heater under the sink cranked to “high.”

When I shut the door, the warmth from the space heater collects in the air, and pulls moisture out of the smoothing compound. Then I will open the door and let the floor fan pull dry air-conditioned air from the hallway into the room, pushing the hot, humid air out.

Done enough times over a long period of time, you can get smoothing compound to dry more quickly than it would on its own.
