I'm thinking of putting drywall over old drywall. However concerned about the dust from the drywall mud used

Question

Is there anyway to sand or apply something in place of mud that wouldn't require sanding. This is not an empty room, so am concerned about all that dust getting into my existing habatat.

Answer 1

You should have no problem putting dry wall over the old. You shouldn't need more than 1/4", 3/8" at most.

Be sure to first extend all the outlet boxes flush to the expected surface depth so the wall plates will be flat.

You really don't have to "sand" after floating. There are "wire screens" made to do the job, without causing airborn dust. You can use a drop cloth on the floor to catch most of it. And it doesn't have to be perfectly smooth. You can apply a heaver stipple and cover all the imperfections.

Answer 2

You don't explain the very strange notion of applying dry wall over existing drywall.

The job, no matter what you do, drywall, mud, paint, paper, spun cotton candy, whatever,,, is going to demand that you cover furnishings, flooring, etc. Plastic drops, tape, whatever.... MOVE the furnishings OUT.
