I'm curious about what causes this and how I can prevent it.
Any thoughts?

I have a two-part answer. First, if you are mudding over stuff that has been painted, the moisture cannot go into the drywall, thus causing it to come back out. Second, some of the old Union Men put a little bit of soal in their mud when mixing, thus keeping out many airpockets. Hope this helps, Rusty.

Adding soap means not having to add water. The soap is a sufactant and basically makes the existing water wetter. I get bubbles on new drywall and old. Right now I am skim coating painted walls and I get bubbles on the second float. I sand them away when dry, or fill with a spot coat.

I prime before working on old work. Bubbles have become a thing of the past since then.

Re: Air Bubbles In My Mud


I get micro bubbles in mud when I mix it with my little paint mixer bit. Don't seem to get them when I use the fullsize mud bit. They are really annoying, but a couple extra passes over seems to pop them. Now I just need to learn to keep the little bits of gunk out of my mud!

Two differant things, adding dishwashing detergent will not help this!!!! (truth is, it won't help in new construction either,, but it does make your mud smell nice an lemony"
Bingo! I miss you Capt!!!

Re: Air Bubbles In My Mud


I was in the drywall supply house is Spokane one day and the manager asked me if I had ever used a product that they were thinking of stocking called "Dr. Smooth Mud". Why yes I have I said as I smiled. I told him that some drywall tapers add liquid dish soap to the drywall compounds when they mix it to eliminate pock marks aka air bubbles etc. I told him "Dr. Smooth Mud" smelled like dish soap. He asked if the dish soap worked. I told him it seemed to help, but was no miracle cure. For the record, it didn't show up on their shelves.

An old finisher, probably the best i have ever seen told me this. The air bubbles happen when your skimming old painted walls because paint acts as a sealer to the surface. So when you put mud on a wall instead of the moisture soaking in like it does on new board it comes out and bubbles.
