I am getting insane amounts of air bubbles in my third coats of spackle. I have done alot of spackling and have never had a problem to this extent before. Here is the situation. Mobile home with drywall with a “finish”on it. It is a light texture paper, kind of like Durasand but only 3/8” thick. I removed slats over joints, filled were it needed, taped joints(paper tape), second coat, lightly sanded and wiped off and procede to third coat. Iam getting insane amounts of air bubbles on the third coat. I can’t figure this out. It does not bubble on the finish of the drywall or over the tape, but it seems to be were i feathered the second coat . I am using green lid mud(all purpose), lightly mixing with drill, no additives. I even tried another knife to no avail. What is up , this looks like harry homeowner did it and is making more work. Any ideas?

well, consider this a bump to bring the thread back to the top -
I have heard of adding a bit of dishwashing detergent to the mud, but I am not an expert -
I did try that with one panfull but no help. I have also heard not to do that when spackling over paint or wallpaper.
Are you getting air into it when you mix?
I dont think so. I dont mix for very long and not at a real high speed. Do you think i need to mix more?
I doubt that mixing more would help, unless the mud in the bucket has bubbles in it. Most likely the bubbles are either getting mixed into the mud, or when you press the mud onto the surface you're compressing air behind it and that then bubbles out.

The stuff that I have seen has had what appeared to be a vinyl "wall paper" on it.
You might try putting a sealer/primer on it.

I have been having the same problem.
Only when going over wall paper or painted area when doing a patch.
I have talked to many people and they seem to be having the same problems.
Something different in the mud?
I was wnodering about the mud, but i have used two different buckets bought 3 months apart, unfortunately both fron Blowes.
we have been having this problem for awhile (many buckets)wonder if the formula was changed?
I have that problem when spackling over an already painted surface. It seems that, sonce the painted surface won't absorb moisture, it goes the other way, creating bubbles.
I realize what I just wrote doesn't make a lot of sense, but somehow the principle is there.
I usually have to give it one more coat of compound than normal under those conditions.
