Shrinking Joint Compound

Is there any joint compound that doesn't shrink? When drywalling I find it cumbersome to apply multiple coats of compound to deeper areas. Even screw heads need a few coats!!!

Don't use premixed joint compound, which comes in the buckets! Buy the setting type compound (hot mud), it doesn't shrink! This comes in the bags and needs to be mixed with water for use. I use the 90 min mix, it gives me a working time of about 60 minutes before it starts getting firm.

What's nice about setting compound is that after it sets up you can shave off high spots with your knife, because the compound is still moist. This prevetns alot of sanding. I do very little sanding now that I use a setting joint compound.

Good Luck! Very Happy

Thanks so much for the tip! I always wondered why someone would buy the compound in the bags...now I'm wondering why someone would by the premixed stuff!

Thanks again!

I painted my way thru college and one thing that always worked well for us is to caulk existing cracks and then using topping mud to smooth out the cracks before painting. Caulking because caulking will flex a little, topping mud because topping doesn't leave those annoying little holes like joint compound does. Have fun.
