Curious about the different ready-mix compounds. I've used regular joint compound for drywall repairs and DAP Plaster Repair for plaster walls and some spackle for small nail holes. All has worked well, but just curious about their differences. I've used joint compound on some of the plaster repairs and wondering if it will hold as well as the plaster repair. Also, since spackle fills the nail holes wouldn't it fill the cracks as well (less sanding involved vs joint compound or plaster repair). Then there is the "lightweight" spackle, lol. So just what is the difference in all this stuff other than the weight....a 32oz tub of plaster repair is the same size container as a 3lb tub of joint compound. Chris suggested I use the Easy Sand 90 on bare plaster to "seal" the cracks and it worked well, but I would never have known to use a "setting" compound. I understand it's to seal the bare plaster and provide a moisture barrier. For the second round of mud I used the plaster repair - worked good also. But just curious about some of the ready-mixes. I'm on my 5th room now and have 7 more to do so thought I'd take time to ask about this to make sure I'm using the right stuff in each room. Hope that makes sense, lol.
. Oh my, these inquisitive minds sure ask a lot of questions, huh.
