Hello all,

I am in an old house with plaster walls. In one bedroom a roof leak caused
a whole section of plaster to fall off the ceiling and at an inside corner.
The hole is one big section, not multiple sections. It's size is about 5' X
8' and the plaster is a bit greater than 1/2" thick.

I have some questions:

1) Where can you buy the silica-based plaster (brown coat) for the base
coat and same question for the top or finish coat? People at home depot and
lowes look at me like I have ten eyes in my head.

2) How thick should the first coat be?

3) Is it just a base coat and a top coat or two base coats and one top
coat?

4) I visited
http://www.diynetwork.com/diy/hi_wal...685862,00.html .
Are there any other sites that described this ancient process?

5) Do I need the make the plaster thicker for the ceiling section?

Thanks for any input from this knowledgible group.
