plaster jacks If you are looking to buy plaster jacks, end your search. They haven't been made since 1951
I brought out my plaster jacks for this ceiling. Plaster jacks allow the height of the scaffold to be adjusted in 3 inch increments. We covered the floors with a layer of plastic and then a layer of Correx, sort of a plastic masonite. The boards clamped to the jacks are called batts. They can be 2 by 4's 2 by 10's or whatever.

Homemade bench type scaffold is used for the lower ceiling the scaffold is good to go
Homemade bench type scaffold is used for the lower ceiling. The old steam heat radiator is disconnected to allow us to patch behind it. Filled with planks, the scaffold is good to go.
old lime and sand plaster is stripped off in Baltimore, Maryland. The ceiling is furred down with RC-1 channel.
First the old lime and sand plaster is stripped off the wood lath and put into contractor bags. The wood lath is then pulled off and put into bundles. The ceiling is furred down with RC-1 channel. The idea is to take out at least half the waviness and provide a frustration free surface to screw the plaster board to. These old joists can be super hard.
blue board, or veneer plaster board veneer basecoat plaster
We put up blue board, or veneer plaster board with plenty of screws. We put plastic mesh tape on the joints. It says fiberglass tape on the package, but there are no glass fibers in this tape. I painted the boards with plaster weld for insurance my ceiling won't fail. This probably wasn't necessary, but I heard of someone having failure using this brand of board. The veneer basecoat plaster is put on thick and rodded off with a homemade slicker. The ceiling is almost straight now. The surface of the basecoat is roughed up using a stiff brush.
Metal corner bead forms the arch Molding plaster and lime
We are white coating the ceiling and truing up the edges with a rod. In other words, we are straightening up the finish coat with a straight edge. Plaster is troweled so slick the flies can't walk on it. A little exaggeration.
Plaster is usually loose under windows that have had air conditioners Metal lath is screwed on over the old wood lath
Don't forget under the windows. Plaster is usually loose under windows that have had air conditioners. Metal lath is screwed on over the old wood lath and cut to fit.
