Everything you needed to know about Plaster
Now that I know that plaster is basically slaked lime, gypsum and sand, and that I can repair stucco fairly rapidly, I have been doing some research because eventually I would like to finish some of the rooms in the basement. I read somewhere that basement walls in old houses were plastered to stop moisture from passing up to the upper floors. Lime plaster absorbs moisture it seems.
Today I was applying a 3rd coat of joint compound on my parlor walls to smooth them so that I can finish them up later in the week with a thin application of "topcoat". While I was doing this I got to pondering on the ingredients of the stuff. Well, HERE they are in case you just had to know.
Then I found THIS information. If you are hell bent on destroying plaster walls because they are cracked, you should read it. Then there is THIS site to read for additional information.
I do what is practical since I always find that there are several ways to do the same thing.
I have noticed that the longer it takes to get this place fixed up the better I get at doing it though!
