Recently we had some water damage on inside walls, after which the thin
layer of plaster (less than the thickness of a dime) began to peel.
I don't know exactly what lies underneath, but this is a 90-year-old house.
It appears to be a sheet-rock type material. This foundation is undamaged.
I've never attempted plastering but migh give it a try on this fairly
But I know nothing about it. I gather you begin with a powder which must be
water-mixed into a paste-like consistency.
Are there different kinds, or just a generic plaster?
I suppose I would put it on as smoothly as possible with a wide trowel, then
sand it when dry.
Do I have the right general idea? Any suggestions, or instructive web sites,
