I would like to parge the walls of a shower does anyone know of a product for this application? I would like to color it. Would thoroseal work? Could I tint drylock? I have used the epoxy and sand wall covering but want a different look. Thanks

Interesting question. I don't think thats a solid enough substrate for parging, which is the application of thin layers of Portland waterproof cement on a block foundation wall for moisture proofing purposes. (according to this construction dictionary) But I am curious as to what type of finish are you after?
I'd be tempted to first waterproof the durock with Red Guard. I think the water will wick right through any cement product. Plus, when the house moves, it will crack in the corners, and then water will get into the walls that way.Red Guard is only about $40 a bucket. It's cheap insurance and you should be able to parge over it, just like you can tile thinset over it.
That was what I had in mind. I have never used it though; it says that it is a crack preventer would you recommend fiber tape in the corners? thanks for the info

Yes - tape all seams and corners. I believe the directions say to apply the Red Guard with either a trowel or a paint roller. I think the roller would be much easier. Usually, two coats are necessary. Watch out, it's sticky and messy.Good luck.
keynes cement...really a plaster product, but used for waterproof walls for many years...
sorry KEENE'S cement...a fully hydrated gyssum product, that is mixed with lime to get the desired water resistance
I will look into Keene's cement. how smooth can you get it? I have tinted plaster walls now and would like them to flow together. Thanks for the info
