Yes. Hopefully this is kitchen backsplash application you are asking about. If that is the case, no waterprofing would be necessary and you can bond directly to sheetrock.

Better work quickly
I was installing a backsplash at my daughter's house, so there were many short interruptions to my work. I absolutely hated this grout. It had to be mixed and I did keep it tightly covered, but it dried very quickly on the wall before the tiles could be applied. It's adhesive qualities were just so-so at best. I bought it because it was recommended for the glass and metal tile I used. I've used premixed adhesive on previous glass tile jobs and liked it MUCH better. It did look good behind the glass tiles.

Do not use for glass tile with mesh backing
We purchased this more expensive mortar option because of what the package claimed and were willing to pay more for a smoother install. The mortar did not do as claimed so we then purchased cheaper premixed to continue our backsplash install. No difference noticed. Once the first section we did with the pricey mortar (this one) dried we were mortified that we saw mesh through tile. The section we did with cheaper premixed mortar did not. We now have to take down section with this mortar and lose money. The tile we chose is not cheap and we are not happy. The picture to left is with this mortar.

I use this product for mosaics on recycled surfboards and find it works great with the "push in" technique for strongly adhering all kinds of mixed media to the board. No grout needed. The consistency is thick and stickey for easy use with a palette knife and stays workable for an hour when mixed in small batches. It's fun to use and can be colored with powdered Cement Color also available at Home Depot. I especially like that I don't have to buy a 25-pound bag of Thinset for my projects.

It was good. It does dry white, white but I never knew if I had the right consistency. I was able to make little bitty amounts when I had just a wee bit left to do.
