   There's different kinds of plaster. Here's one link http://www.chargar.com/mc.htm . Or google "waterproof plaster". I've used swimming pool plaster for hot tubs, and it'd work for a shower wall if the substrate was appropriate.

   I would like to plaster the walls of my shower.  It seems like you have had experience with this?  I now have skim coat plaster walls in the bathroom with 1/2 durock in the shower area.  my thought was to parge the walls with thinset then coat with red head waterproofing then plaster.  I would appreciate any help.

   Plaster will be failry absorbent. I think I would avoid it. How are you handling the pan membrane where it goes up the wall? Do you extend diamond lathe from the CBU scratch coat over the pan area where it goes up the wall? How are you intending to afix the lathe? You aren't going to nail the lathe through the pan, are you?Regards, Scooter"I may be drunk, but you're crazy, and I'll be sober tomorrow." WC Fields, "Its a Gift" 1934

   things are a bit different hear in the uk.

   almost all our houses are built of bricks.

   so the plaster that goes on the walls isn't drywall ( at least not on older houses) the water prrof plaster that i think they are talking about is a mixture of portland cement, fine sharp sand and a waterproofing agent.

   its probably similar to external stucco in the USA.

   it can be put onto timber framed walls but for all the effort you would be better off using a tile backer board or if the area is to be painted etc.... a water resistant sheetrock ( in the UK they are in green paper and have glassfibre in the core)

   good luck

   ps in my bathroom the brick walls have a cement render and the timber ones have wedi board.

   Yep, plenty of waterproof plasters. Do a google search for "marmorino." Great in bathrooms. It can be colored and polished also. These are the plasters that have been on the exteriors of buildings in Europe for a couple of hundred years. Long before the late 19 century and the advent of portlands. What's tearing up these plasters on these old buildings now is auto exhausts. Streets are too narrow in too many places.

   Don & all:

   Thank you for your responses. Don I am intrigued with the possibilities using color as you mentioned. I wonder how the cost of this might compare with tile. Currently our contractor's sub has bid the job including backerboard (Wonderboard?) mud pan and tile (laid straight, no deco) at @ $22 per square foot, including installation. Several thousand, all told. Any idea if a plaster product would be more, less, or similar? I know that's a tough question, but I'd like to have some idea how the cost might compare with tile before asking our contractor to look into it. Hate to waste his time, and hate to pay Change Orders for simply looking into a possibility.  :)

   Thank you all again for responding.

   Linda

   A lot of it will depend on where you live, but you should be able to get a good marmorino plaster job for no more the $15 a foot. You can go beserk with finishes with marmorino though. Add some fresco work along with some metallic finishes, and it can easily go over $100 a square foot. Artists are expensive. It's really up to you.

   i think i've seen something similar with marble dust or maybe glass beads in it and it catches the light really beautifully.

   Yep, marmorino's contain a percentage of binders made of marble dust. Of course this just complicates the issue even more as marbles come in wide array of colors and grades. The dust does play into the polishing of the plaster.
