brought out my plaster jacks for this ceiling. Plaster

|We covered the floors with a layer of plastic and
then a layer of Corex, 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.
If you are looking to buy plaster jacks, end your search. They haven't been made since 1951.
bench type scaffold is used for the lower ceiling.
The old steam heat radiator is disconnected to allow us to
patch behind it.
planks, the scaffold is good to go.
|First the old lime and
sand plaster is stripped off the wood lath and put into
contracor bags. The wood lath is then pulled off and put
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.
|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.
|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.
|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.
|Moulding plaster and lime sets fast and
allows for quick completion of patches.
||A few other loose areas are repaired, and
we are marching downstairs for phase 2. Please check back.
We have some cool stuff to do.
