Type Cement for Floor?

[G Schulz]

I need to replace a couple of broken ceramic tiles. I was wondering if anyone knows what type of cement to use. I'm thinking a modified cement since it is OSB for a subfloor, or is there a special type of cement for RV's given that the floor does flex some.

When I purchased our coach the toilet ring had been allowed to leak for a long time. I removed the ceramic tile around the toilet, cut out the top layer of OSB, replaced it with marine plywood, then used normal ceramic tile cement from Home Depot to reinstall the tile. That was 5 years ago and no problems at all!

There are usually 2 types of thin set at most of the big box stores.

One is used on concrete or cement board.

The other has a polymer in it and allows some flex.

Another option could be to use a adhesive, like liquid nail. In my BS house I had problems keeping tiles on my stairs (I will never put tile on stairs again due to expansion and contraction). I finally resorted to Liquid Nail and no tile has popped since.

The liquid nail suggestion is something I never thought of. Probably would have been close to what the factory used. It stuck to the tile but didn't have a good bond with the OSB though. I actually used a modified cement today. I used it to cement the tiles in front of my fridge where the end slide roller runs on the floor. The old tiles were just all shattered. Too much flex with all the weight on them I guess.
Thanks for the suggestion.
