I have just installed cellulose insulation in my two by four walls. I had it wet sprayed in to the open wall cavity from the inside of the house. The installers said to let it dry out one-two days before covering it with drywall. The last time i used it the drywaller complaned about his joints not drying. It has been two days and the walls are still quite wet. The job is in western NC so we have lots of humidity in this climate. I am afraid to cover it early not wanting to encourage mold groth in the walls. Any ideas on how long to wait? Should i get a moisture meter?

What do you mean by wet? It should only feel damp when you put your hand on it(kind of like a SLIGHTLY damp sweatshirt) even right after installation. If it was wet like dripping water, they used too much water when they installed. In the beginning this stuff was installed much wetter than it is now, It never should have any "free" water.
Anyway, if installed right so its slightly damp, I like to wait a week, but have drywalled after 2 days when needed
Don't cover if it feels wet at all. Like the other guy said ... should be damp at first ... definately 'moist' right after install ... but not WET. Sounds like maybe the installer wasn't really sure ... I'm thinkin a week ... especially in humid situations ... are you ventilating ... open windows etc? It can't dry out if you don't let the moisture out of the room.
Also ... maybe apply some temporary heat to the room if it is cool weather? Heat and ventilate when it is cool outside ... will speed the drying process.
Thanks all for the advice. It was not dripping wet but quite damp. After two weeks of ventalation it is now hardly noticable.
