Been noticing my brand of hot mud shrinking a lot when drying. Nat. Gyp. Quickset Light. Don't recall it being this bad.

Did job yesterday with Sheetrock brand. Boy, been a while since I used that. Their 20 sets a lot quicker. But I liked it. was working in two different areas in home and went back and forth with following coats.

So, how about that shrinking hot mud? Has it always done that? Am I nuts or what?

Can't remember the brand, but recently I had a repair and used 20 minute. Brand new bag. An hour later it was still wet.:blink: We were a 2 hour trip from the closest hardware store, so we waited it out. 2 hours and it was still soft. Came back the next day and it was dry but cracked. :censored:

Put in some 45 minute and 30 minutes later I was sanding. Go figure.

Wonder if your supplier got a bad batch?

Sheetrock brand is all we have available to us at the moment. I prefer Hamilton due to the smooth consistency but I have found Sheetrock is more predictable than other brands.

It's a fast setting compound ..Not fast drying .

BTW....to answer your question no....I don't think it should shrink much if at all. I rely on hot mud not to shrink.
It should swell.
Correct..............

I ran some bead last week with 5 and it shrunk! :eek: I knew something was going on.

Possible too much water in the mix? I've mixed hundreds of bags, don't think I'm doing anything any different.

Just bought four new bags yesterday. I'll see how it goes.

I was gonna be a smart ass and say read the directions and make sure you didn't over water it...but at this point in your life I think you've mixed enough bags to know what you're doing.

Weird, but maybe. I was thinking the same thing.
Not mixing any for a while. Next drywall job is end of next week.

Normal thickness..........Everything normal way. Actually, now that I've been thinking about it. The last few bags have been shrinking.

I'll see how the new bags I picked up the other day work on the job I'm doing next weekend. Yes, you heard right. I took a job that I have to do Fri,Sat,Sun and complete Monday. Demo,frame,hang, finish and trim. No paint.

First time booking job over the weekend. Referral. So I thought why not? One weekend ain't going to kill me. Wife said just take the boat out and go fishing on Tuseday. :thumbsup:

Just so you know...........I used a bag of 20 yesterday that I have had for several yrs. It took about an hour to set............with fans on high.

I know,I know. Don't start Inner. :laughing: It was an experiment. :1eye:
