Thank you for the heads-up. Because of cost, I can see why you limit its use to time-sensitive jobs. So, it's superior in every way, but will eat up your margin like a Hemi guzzles gas.Mike Finley said:I'm not a drywaller by trade...
I am under the understanding that setting compound is superior to all purpose compound (or sometimes referred to as drying type joint compound) in regard to cracking. Because all purpose compound is vinyl based it hardens because of moisture evaporation, and therefore shrinks more, where setting compound hardens due to an internal chemical process and shrinks much less. I have always been under the understanding that setting compound gives a better bond, has less shrinking and cracking and drys to a harder finish.
The disadvantages are it costs about 3x more than the all purpose stuff. You have to mix it from powder and you have to use what you mix. All purpose comes in a tub, it is pre-mixed, you can use what you need and re-cap it.
But being professional contractors you have to use your tools and materials like a pro golfer, pulling the right club out of the bag for the conditions you are in.
