Going back to a thread that faded away at the turn of the year. YCFriend discussed briefly mixing PVA & plaster of paris in mud to do a finish coat on an entire wall. I sent him an e-mail asking further questions - he suggested posting it here so everyone could benefit from the info.
I like your ideas on mixing the PVA primer, plaster of Paris & mud for doing walls. The way I read your last post, you mix a fairly thin, runny mixture of half a gallon of PVA w/ 3 gal of mud & a cup of PoP then roll it on the entire wall. What length nap do you use? Does it flatten out? Sounds like it nearly becomes slick as glass. That's what I'd really like. Need a hint on details of application. I've been working to smooth out all the dings & dents then putting on a layer of Sheetrock First Coat by USG. It is pretty thick, and doesn't really lay flat after rolling it. Still see a lot of roller texture. What does such a small amount of PoP do? Doesn't seem like it would harden it up much at all w/ only a cup in nearly 3.5 gal of muck.
How far does 3.5 gal of this mixture go? I have a 22X24 living room to do - walls & ceiling. Also have a BR & a kitchen, but they are much smaller.
Appreciate any help you can give me.
