I was reading a tread about how little air holes appear in drywall mud. There were multiple suggestions of adding a little ivory soap and water to drywall mud to make it as smooth as a baby's butt. How much soap to water to mud would all you pros out there recommend?
It has been a while since is did it but it did have an impact on the air bubbles.
How much soap ? Very little, much less than you think.
I have done the soap, maybe a half tablespoon for a gallon or two of mud, but i do not use any water.
I remember adding too much the first time and it was a little thin/loose, hard to work with.
I used generic dish soap.
You can always add more but you can not take it out. ( I have cut this board twice and it is still too short )
The issues with air holes is mainly when you are using the premix joint compound.
What my crew does is:
- start with empty bucket (left over).
- Scoop in about 1/3 of a new buck of joint compound.
- add joint compound powder
- add water (of course)
- add a squirt of dawn (for bucket - about as much as you would use to wash your hands after you work on a car)
- the mix should come out less thick than peanut butter or Nutella
- the key is the mixing it hard with a good mixing paddle on an old drill.
If you are going to use premix good luck mixing it in the bucket it comes in. It for sure needs a bit of water and a dab of soap but you probably won't have the power to mix it or the space. You will need to mix a little at a time with just a tiny bit of soap and maybe 1/2" cup water to gallon. (if you put too much water in, add more compound)
