When I moved into my house I had a lot of loose plaster on the walls. Mind you, this is not drywall, but scratch coat plaster coming up. Not wanted to actually spend 3 years as a journeyman learning actual plastering techniques, I research alternative products and came up with one called Durabond. There many different types, but I used 45, 60 and 90. The lower the number the quicker the dry time, but the softer the surface. I ended up using 90 which had a sandable dry time of about 2 hours and mimicked the resilience of the plaster the closest. It is a dry compound, but I have had some experience mixing actual plaster so I am comfortable with the ratios.
It took a few applications, but I got pretty damn good at large plaster repairs. I think I ended up with tow passes(real plaster work should take one, and if you've ever seen a someone do good plaster work, it's pretty impressive) It sands pretty will with about a 120 grit and nothing more. I even used a disk sander at real low speed and all was well. It was a dusty friggin mess, but in the end, I think I'm the only one who will know where the patches were.
Granted, this isn't drywall, but it's in the family. So if you need a quick drying compound, go with the Durabond.
Thank you for the advice, I will definitely look into it. I have a ton of lathe and plaster in the house too.
I'm finally putting the sand texture on the walls this week. the damp weather last week slowed the drying time on the joint compound a bit on the first two passes.
I'll post a picture when its done.
