Re: Air Bubbles In My Mud


Why are we talking about air bubbles?
It's a normal thing when mixing mud, everyone gets them on the first and second coat ... it's like starting a thread about dust.

Well perhaps its cause he wasn't talking about pock marks that are caused by air in the mud, he was talking about the "bubbles" that come up when you are mudding over an OLD wall,,,,, thats an entirely differant thing.

O'laaaa

We do mainly flood restorations so every job involves butting new sheet rock up to old, and I always get bubbles or fish eyes in a nice row on the old painted drywall. Tries the liquid soap also various mixing methods. Now i just scrape the dries second coat with a trowel, and apply a light skim coat which fills in the bubble holes. Takes a bit of extra time, then again we aren't doing new construction and they allow us some leeway cost wise.

It took me 5 minutes to read that.

Is this what you were trying to say?

I sand a lot. I've seen a lot of different texture from many different tapers. Most defects in the mud comes out with a good sander. What doesn't, I just mark it, let the taper know, and they go back and touch it up.

Re: Air Bubbles In My Mud


Iím not a master sheet rocker or sander but I know if you hand mix your joint compound you are less likely to have air bubbles, same goes with mixing mud and grout for tile.
I have also seen mex putting soap in when they mix up the compound.



What makes a good sander: A good spackler

Several good points mentioned here, but one I didn't see was that you'll have less bubbles/pinholes if you knife in one direction only.

Okay children,,, pay attention,,,,,

The "bubbles" mentioned in this post,,, are NOT the "pock-marks" caused by "air-bubbles" in the mud. But rather the "bubbles" caused by effervesant bubbles caused by a caustic reaction of putting drywall compound over an "OLD WALL"

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"

Re: Air Bubbles In My Mud


Aye aye Capt. These bubbles are particular to painted surfaces; the statement about the surface not being able to absorb moisture seems to make sense.

Never tried the soap trick, although a simple solution would be nice. The trick I learned was to put on a thin layer of mud and wipe it TIGHT, pretty much taking it all off, before loading it proper. It takes a few extra seconds per joint, but when the mud goes on the second time the bubbles are pretty much nonexistent.

Re: Air Bubbles In My Mud


One of the other things that hasnt been mentioned but is something to consider is the type of drywall mixer you use. too many use convention drills to mix and thus creating a lot of air into the mud. i know the fish eyes are inherant when placed over prepainted surfaces however they can be greatly minimized by using a proper drywall mixer. I have a makita and a ridgid and actually the ridgid has an even lower rpm than the makita does.

it doesnt negate all fish eyes however it does minimize them over a conventional drill

Re: Air Bubbles In My Mud


put a small amount of ivory dishwashing liquid in your joint compound when you mix it. That should take care of the bubbles.
