Drywall jobs are a common occurrence in my line of work. I was fixing a cracked seam at a customer’s house and had about a 15 mm deep gap to fill. Generally, I’ve just used the pre-mixed stuff from a bucket, but that dries so slowly and shrinks so much that a job like this would have needed to be spread over at least four days.
Decided to give the quick-setting bag stuff a shot, and wow - what a difference. Not only could I pre-fill the gap in one day, but I also managed to get the tape over it, leaving only the finish coat for tomorrow. This will save me literal months over my career.
I love discovering good new products and tools.
My understanding is that most drywall products are modified plaster of Paris - modified to cure slower. Regular gypsum plaster of Paris is really fast, like 10 minutes, and not only does it not shrink, but it slightly expands. And it does warm up. Not sure if that’s what “hot mud” is in the industry.
Pretty much exactly what hot mud is. 😀
