Where to get unmodified thinset

[mcdonaldb]

First let me just say i have been enjoying this forum for some time now and have never had anything to ask, but now im in the middle of finishing my basement and was planning a steam shower.

My question is related to hydro ban and vapor barrier, i plan on doing a preslope and then PVC liner, CBU on walls and sloped ceiling, then mud bed and hydro ban. Im a bit confused on if this is even the right product(hydro ban) to be using in a steam shower since it is not a vapor barrier? Does this mean i should be using a 4 or 6 mil plastic on stud walls first? or is hydro ban just not the right thing for a steam shower. Any help would be appreciated.

thanks
brian.

From the Hydroban PDS

▪ DO NOT use as a vapor barrier (especially in steam rooms).

Uses for Hydroban

▪ Steam rooms (when used in conjunction with a vapor barrier).

Laticrete 9235 says the same thing but Hydroban's vapor perm numbers are lower.
Are you doing cement board walls? or mudwalls?
Pretty much you need a vapor barrier, cement board, Hydroban, tile. But due to the fact that steam rooms are such wacky fun; you should consult with Laticrete Tech peoples so you can get a proper gameplan going before beginning.

yup what Royce said

and have u considered using schluter kerdi membrane instead?

[mcdonaldb]

Royce, im not sure what mudwalls are? i was planning on using dense shield.

As for kerdi, i have have considered it but feel the price might be too high for me.

I have an email out to laticrete and am awaiting their reply on the matter.

Laticrete state that you need to use a vapour barrier in conjuntion with there hydroban.Laticrete also have a steam room manual that you may want to get , it will help you with your build. Just remember steam showers are alot different than a regular shower build.Im sure a Laticrete rep will be in touch soon. Great products.

Interested in building a Steam Shower you say ...?


Take a look at this:

Tiled Steam Room and Steam Shower Technical Design Manual

The goal of this manual is to provide the necessary information to help ensure a proper and long-lasting tile installation in a steam room or steam shower environment.

PS - YES, HydroBan and a "full Laticrete System approach" is the "right" way to do a Steam Shower.

As for kerdi, i have have considered it but feel the price might be too high for me.

are you sure? I would think that the incremental cost for the Kerdi materials (doing a mud floor, not tray) would be pretty insignificant in the grand scheme of the total cost for a steam shower. With the ability to use drywall as a base, I think Kerdi greatly simplifies the process and reduces opportunity for error. This is not the type of thing you want to cut corners on.

Talk about service from Laticrete. Henry is one of/ THE top person over there.

SR-614 details are the ones you need. 613 details are the ones for the mud walls (ie-cement over lath)

Check out the manual. If you have any more questions concerning how to do various items, we'll be happy to help answer anything. The Laticrete people can as well.

[mcdonaldb]

I did hear back from laticrete and was given a drawing that showed a vapor barrier being used over the stud wall.

I now am considering moving away from hydroban and going with a kerdi steam shower on mud preslope. I have a few questions related to this, should i start a new thread or continue in this thread?

[scuttlebuttrp]

Just keep everything here in this one thread for continuity. The moderators can change the title if you want. Just tell them what to change it to.

well after H.B.R. took the time to chime in with some very good info ,the door STILL seem's open for others! Nobleseal has the lowest perm rating at .05.
Details can be veiwed at my link and I'll be happy to answer any questions I can.(others might even help with that part).

I no longer see y'all's steam shower detail on your website, Eric. Ain't never been real intuitive to find them CADs, but even knowin' what to look for I don't find one.

If there is one, maybe you could post a link?

There is a group working on updating or changing the details in the TCNA handbook.The one item we all agree on is, a vapor membranes needs to have a perm rating of less then 1.0-The IRC has 3 classes of membrane's with class 1 having perm rating of .1 or less and is cconsidered impermeable,class 2 -.1 to 1. is semi -impermeable.
Nobleseal has perm rating of .05 tested to E-96 proceedure E 100 degrees.

Thanks, Eric. Now that I see the drawing still exists, I still cannot find it on my own on your website. More hints?

And we're ever so glad work progresses on the new steam shower details for the Handbook. I know y'all been workin' on that this long time, but I'll always maintain it's because of all my whining.
