I am laying a tile floor in my bath. When I pulled the carpet up I found one of the sheets of 5/8″ sub-floor had delaminated. I cut out the 65″x 21″ area, went to my supply house and found that all anyone now carries is 19/32 thick ply. My question is, will the latex-portland mastic between the sub-floor and the backer board make up the 1/32 nd difference or do I need to cut some shims and glue them to the joists??

I don't consider myself a tile guy by any means. I've done a few jobs in some of my rentals. A 32nd is really nothing to sweat,just throw on a little more adhesive.
Thank you for the advice. It was just the feedback I was looking for. I would hate to lay a floor and then notice everyday that there was a dip. The area in question is not in a really obvious location.

Yeah, 1/32" is no big deal for cement-based mastic. In fact, the old stuff may have been that thick -- it's just "truth in advertising" that they now tell you they sanded off 1/32".
Hope ya mean ...
Latex Portland "thinset" ...
not "mastic. (no mastic on any floors)
and that little bit ain't nothing at all ....

I did mean thin set. I was typing out the message while my wife was calling me to dinner and my mind came up blank with the material after the latex-portland and all I could think of was mastic.
I appreciate your feed-back!

sounds like no problem at all then.
Happy tiling ...

are you sure you want to stick tile to a plywood underlayment ? i would tear it all up and install wonderboard or hardibacker .
I probably wasn't clear enough in stating my problem. I AM going to use a backer board. The backer board should cover the 1/32" variation, but I am cautious enough to ask for some guidance before laying down the backer and the tile and then staning back and going "gosh that looks bad."
I plan on going with Georgia Pacific DensShield Tile Guard. I have used Hardee Board in the past, but it is sure hard to work with.
Thank you for your reply!
