Tile floor prep.
Hi all,
Quick clarification question for anyone who's done this before. Working with new construction and I'll be installing a tile floor in the bathroom area. Plywood sub-floor is in place, and I'm getting ready for tile. I plan to add a layer of 1/2" cement board over the sub-floor, and have read that I need to set it in a layer of mortar before screwing it down. No problem.
Question - is the mortar I use for this step the same thinset mortar product I'll be using to actually set the tiles? I believe it is, but just want to be sure before I head off to purchase.
Thanks for the help!

Thank you for the confirmation - I'll be sure to grab a few bags to mix myself.
One additional follow-up. Once I have the CB set in place and screwed down, should I allow the thinset to cure before I begin laying the tile on top, or can I dive right into setting tile?

Some cement board manufacturers require modified thinset under their board while others want unmodified. Some others say either or. You should go to the manufacturers website for you particular board to verify what they want you to use. That'll make sure you dont have warranty issues if something goes wrong.
You can set tile on the cement board immediately after installing it if you want to.
For the record, you don't need 1/2" cement board on a floor. 1/4" cement board is actually made for floors while 1/2" is generally for wall applications. Cement board isnt structural so it wont make your floor any stronger. If thats what you are trying to do, add more plywood first (3/8" minimum), then the 1/4" cement board.

Great - thanks for the tips. I'll be using Durock CB, so I'll check what type of thinset they suggest before buying this evening.
To be honest, I had only planned on using the 1/2", as it was what I had seen in the store the other day. I'll have to look a little closer to see if they offer it in the 1/4" size as well. Current flooring is 3/4" plywood that seems to be level and secured well.
Thanks again guys, I do appreciate your help!
