Wax for lime tadelakt?

Anyone have an opinion on the type of wax to use on a lime tadelakt shower?  I’ve heard that carnauba wax is good but I’m not sure if I can just use anything at all that says Carnauba on it (even car wax?).  Should I be looking for an emulsion?

Thoughts and tips for a first timer waxing a tadelakt shower would greatly be appreciated.

Cheers,

Hello Kadin - I love words, so had to look up "tadelakt"  where there was mention that the best finish was soap.  No mention of what sort, or how to apply, so over to you for more research.
Went looking . . .https://en.wikipedia.org/wiki/Tadelakt
Carnauba was tends to be expensive, so gets adulterated with other "lesser" waxes and other stuff.  SO, is there enough of the substrate to do trials on to see which finish works best?  

I used lime tadelakt for my shower enclosure. I looked into waxes, saw how expensive they were for what you got, and decided to make my own. I don’t exactly remember the proportions, but I cooked up my own wax (outside, on a hot plate). I think it was about equal parts citrus oil, food grade carnuaba wax and beeswax melted into an emulsion. It’s been about a year since I applied and it’s still performing great.

Have you done the tadelakt yet? It’s a tricky plaster but so cool once it’s finished. It’s my favorite plaster in my house.

Appreciate the replies.

The first layer of tadelakt is oil soap that you rub into the lime as it is a drying.  Some people leave it at that stage but we made a mistake by putting damp cloth on the surface and it created marks that we decided to turn into relief carvings.  Now that we scraped away sections we need to seal that surface and thought wax could be a good idea.

The wax that is made for tadelakt is quite expensive so I was hoping someone could recommends something else.  Interesting to hear about making your own! Something to think about!
