" When you're doing a room like this if you're going to attempt to hang your own drywall or blue board. Be careful. But -- it makes a lot of sense first of all the pay attention to the direction that the strapping is in. Are strapping which are the pieces of wood that are attached to the actual roof rafters are horizontal like this so that means that you wanna. Put your blue board -- drywall in the opposite direction perpendicular to those lines so that you get lots of nailing. Then the other thing that you want to keep in mind is that the larger the board that used. The fewer cracks that you're gonna have down the line if you are seeing that -- going to have to fill and here we've got twelve foot sections four by twelve foot sheets of blueboard. That you know come down and -- in make it much. Quicker and easier job then the detailing if you if you've got openings such is here where we have a skylight. This is absolutely. The most important thing that you have to put in the corner -- because this is going to assure you neat crisp corners. But then it wherever you have sheets butting together. They come with a factory edge and you see that there's actually an indentation on each one of these factory edges and the reason and that is there's so that you can put. Tape over it and so that you can. -- or put in 881 coat like he's doing over here. Which will give you a much stronger joints in between those sheets. But got a Muslim doing you are plastering contractor who was from -- Ecuador but yes lives here in Cambridge I want to interrupt you now because. First of all this always looks so simple when you're just church -- why are you are you putting in. And right off the costs. Effortless right. A little written yet it looks effortless. But the fact of the matter is that it takes a lot of skill and if you really never tried it before. Keep in mind that if you do it wrong you ruined it."

" What what is the type of plastic you're not only using not Unocal base which is makes. -- water in the meaning that you add the water you have about an hour when our twenty minutes and after about an hour you. Had a Little Rock which is -- otherwise known as garbage yeah so you've got to be quick. And it fat let's watch you load up that thought okay but. And we want to take it's so you don't spill widow of the -- And a and it's just watch him go."

" Against something that its annual risk."

" What time it was why you -- trial a little better. About how they are you laying -- it. It's about a -- eighth of an inch and -- finish yet -- my trip. And or what's was thought of already under now the the the part of it it. I can never get right at this part of it. How can you tell that you're putting on the right yes. Well -- you can see you know you -- could -- you good and we did a little less the amount. But I'm. And he tried to leave them later on in a way that even a wrong because you have to come back again. To goal Britain's bat knocking it down. Eventually. The case you don't want to bash we want to put a good amount. Yes because you've got a hold back to the wall above for the time by the time the wall is hot that you actually remove some of it off. Okay. And then once you've got it bond. You have to wait how long before -- steel -- normally happen person like myself would do a couple of walls and then insulate them down whether that would come back again. And -- without two kids going forward again. And he's got taken out all the impurities that you left the first time around okay so you come back admitted a second time while it's still workable Wallace and out a way yes. And then you'll third time you would add water because the mix assassin get hot as we. Continue as time goes by actual -- the next when you come back and use the old lightly water role but it and you would do the same thing over again OK so you won't want times all of the work that you have. --"

Drywall vs. Blue Board
Drywall vs. Blue Board

When choosing wallboard, remember the difference between drywall and blue board. Drywall panels are covered with paper that will take paint directly once they've been taped and the joints and fasteners have been covered with compound. Blue board's more absorbent paper layer is designed to bond with a veneer plaster coating before it is painted.

Bob meets up with Bill Reid of US Gypsum in the barn of the Medford project. Bill differentiates imperial board (blue board) which is skim coated from drywall (gypsum panels) where the joints are taped. In 2000 US Gypsum developed a new core technology that makes the boards stronger and lighter - for easier handling, cutting, and scoring. The screw spacing is 12 inches on center with the screws flush with the paper providing a good, solid adherence to the wall with the screws. The face paper is treated and absorbent to take the veneer plaster and create the bond. These new boards snap cleanly on the ends. The installer puts a back cut on the edge so that the back of the sheet doesn't hit before the front does. The blue board and skimcoat application is typically not a do-it-yourself project. Traditional plaster jobs were very cost prohibitive so, when veneer plasters came along, they became very popular as they give a much more monolithic look than gypsum panels while providing an abuse resistant finish. Upstairs in the studio the homeowner has specified blue board with veneer plaster and downstairs, where he wants the option to tack artwork to the wall, he has specified a traditional drywall and tape application.
