Whether drying smoothing compound ( drywall joint compound ), or primer, hot, dry, circulating air helps speed the process.
i love this old space heater that I got at a garage sale decades ago. It runs when you tell it to, for as long as you tell it to – without “safety” measures that trip other heaters off after a few minutes. (Don’t worry – I keep an attentive eye on everything!)
The hot air from the space heater helps pull humidity out of the air, which speeds drying time.
Works best in a small room like a powder room. Close the door and let the heat build up. Use fans to move air around the room. You will feel the humidity increase as moisture is drawn from the walls. Periodically open the door and use a fan to circulate moist air out of the room.
One thing to note – which I have learned the hard way – is that this gizmo pulls a lot of electricity. And so do some fans. I can use my two box fans while this heater is running. But if I run my more powerful floor fan while the heater is on, it will trip the electrical circuit. And double-ditto if I try to use my heat gun while the heater is on.
