" All four of the main rooms in this house where heavily ornament at both the woodwork and of course the plasterboard. And as we said earlier all of straight plaster was torn down but up previous owner left the cornice moldings in place. We're very fortunate it's a very high style federal. And it probably made up about six different needs and we got all of us in this room except proportionate I guess. -- right we had some water damage behind it and it just. Became human and while we're in the process of restoring it we're gonna show you out of their first let's look at some some of the components here. These. This is a piece that fell off of the the wall. And it shows you profile and make yeah committed against me that most of the cornice is actually built up brown coat and then the actual finished plaster is really about any damage stick -- and the way you achieve all these lines is. -- a template. Such as this which would be the original one obviously would have been probably wouldn't meddle with the -- sheet metal that's been cut to fit from the sample and it gets cold. Through the wet plaster to create that effect. We're doing today is putting the bronco and a that's exactly right yes procedures that he's -- may cut the applied elements after the section run. Then the I can't this -- were mounted it at the wall would have been coming here and it would. And can this lead every television -- right and then the treatments would have been mounted like that on the soft that are called -- lips. This is all agree. That side and in the smaller campus leaves from Canada about exactly and then along the the the lower very lower made up of notes several cast elements that them. Match like this Andy's actually have a like a cornucopia. With fruit and I see what are probably right she's the right keys yes. That's go up there get a closer look at the the rough -- Ralph it's scratching. The plaster now. What -- eighteen and we're looking at over. That's correct. This is the original plaster work. -- missing here of course the pieces that would not fit right into place the trees pieces that. Fascinating to get this close -- to see some of the color it's still there. You see a lot of light blues here which was the columns the one time and we had a picture mold here yet that. Captured some early -- greens and blues what's happened all listed doesn't have the crispness that. And I'd expect unfortunately. The previous owner that tore out the plaster work applied chemical strippers to remove the that's a big mistake right we never apply chemicals plaster because it's porous and once the chemicals getting. It's hard to get out and it can also deteriorate if -- totally destroyed in but if fastening to be right up here next to this war look at the thickness up here. The brown coat the good -- remaining hand split. Laugh. Looked -- here at this detail on the frame that he and that's a mortise and Tenon joint instead of pegging it. With the round dowel that actually driven awaited edit -- goes right -- the -- and a wedge to tighten it up into politics this house apart without having it is a crowbar. You hit they -- is an interest in. They we uses as the plaster washer. And this whole section was loose so we've -- minute drill holes in the fastened -- the plaster washers and screws and that's a mechanical re attachment back to. The and you want to preserve as much of the original plaster in it bits and pieces that you know want to lose it. This is I'm right now yeah. And it's just been nailed up over fifteen pound felt and I actually had to -- a couple of two by -- to help create the profile. Of the cold up here -- exactly right not what is it you're using with the product."

" The distant gypsum plaster I get -- life it has -- tonight attitude but can lightweight duke and after shore. And we can quietly -- I've traveled because to a streaking back. But you -- OK so right now you're putting on the first coat and is there which they're now this is a hot down there in the sock itself. Hot up in New England. And you basically just have to develop a technique. That I have a great technique for spilling it on issues that -- and yes indeed. -- it's fun it's one of my favorite -- now hi how do you deal with the build up that you've got to do appear as well as if he were curved it to fit. The curvature of the Q now. And what it's like you more layers when morally and in the white coat -- is finished it go for a let's watch your technique respect."

" Cover of the wire completely and income back can add more."

" So that makes his makes stiffen up enough that you can now. Yeah it powdered form -- water yet which you don't have so much that you got a lot of -- a productive knows yet exactly. And also apparent -- itself."

Plaster Reproductions
Plaster Reproductions

The lost art of Victorian plaster details is making a comeback - in a new form. Modern manufacturers are finding ways to reproduce cornice moldings, friezes, corbels, brackets, rosettes, and ceiling medallions, using lightweight polymers. Less prone to damage than plaster, polymer details are flexible, paintable, easy to ship, and they come in a wide variety of shapes and sizes.

Patching with Plaster
Patching with Plaster

Chris Borovka from US Gypsum joins Bob explain about patching with plaster. The first job entails patching over an existing door opening. They've put some Imperial Gypsum base up to the existing door frame and patched the existing hole with diamond veneer base coat. Next they put pressure sensitive fiber tape, P-Tape, over it and bonded the entire existing surface. The use USG Plaster Bonder Pink as a bonding agent - it rewettens and re-emulsifies - and put the base coat of plaster over that. Where the wall meets the ceiling, they apply pressure-sensitive tape to the existing surface and butt it in while applying the first coat of base coat. The first coat provides a nice even scratch coat. The second coat should be applied while the first coat is still fully wet and serves to take out some the bad dips and dives and the trowel marks from the first coat leaving a nice smooth finish. The next day you they'll put the finish coat over it. Where the insulators drilled holes into the original walls, the plasters put the Plaster Bonder Pink around the inside of the hole and fill it in with the base coat. They've meshed over the top of that for extra security and then bonded over the whole surface. On the blue board, it's a different type of installation. Shreve applies one-coat over the joints to reinforce them and fill in the undulation that's left from the two end tapes from the butt joints. That sets up for about an hour and then it's ready for finish coat.
