Hey guys any ideas as to what causes and what to do about bubbles in joint compound??
I'm doing some repairs in a rental house and the bathroom ceiling needs to skimmed. I'm floating a smooth surface over what was a sand texture. After repairing some loose tape and paint I decided this was a way to go before reapplying a sand finish. I thought this was a good idea to get a uniform finish. The room is very small so no big whoop, but I can't get rid of the bubbles in the mud...more than pinholes some are probably 1/8". They just appear no matter how I smooth it. The bubbles seemed to turn up after half the pail was used. Is this old mud out-gassing or something?? I wouldn't mind in the first coat or in the patches but this is the final coat (or so I hoped).
Luckily it's a small ceiling so not much time lost. Can this be avoided? I've read about adding a little dish soap to the mud but not knowing how much I'm not about to mess with it.
I figure tomorrow I'm scuff the "domes" off the bubbles that aren't pitts and use a fresh bucket of mud to touch up.
Any ideas about how to avoid this in the future?
Thanks in advance for any help.
