First time posting. So far this place has been a great resource and I’m hoping I can get some sound advice from everybody here.
I have a 450sq/ft attached garage (bedrooms overhead) in a 1959 ranch home. I originally wanted to go with expoxy but have fallen for the look of tile.
Floor is in rough shape cosmetically. If I could post pics I would but this is my first post. Basically there’s a lot of spalling and minor cracks. The worst crack is quite long but there’s no separation. It doesn’t seem to move at all throughout the seasons and isn’t out of plane. Whoever originally poured the floor did a terrible job, sloping it toward the entryway door between the garage and house. I’ll have to correct this in a couple of areas using self leveler.
I plan on using 12x24 porcelain tile from Lowe’s. It’s Style Selections “mitte gray” and rated at PEI 4 I believe. I think I’d do 1/8” grout lines...maybe epoxy grout if I work up the courage.
For the record I’m fairly experienced with tiling. I’ve done a few showers, a countertop and a good deal of flooring but I’ve never installed over concrete.
I have the following questions:
Any advice would be greatly appreciated.

I have the following questions:
- Assuming I can chip away any loose concrete and patch, do I need to scar/etch the entire surface of the garage floor for adhesion?
- That leads me to the question of uncoupling membranes. I’d rather avoid them if it’s overkill for my situation (ditra, etc.). Would rolling on some red guard or other crack isolation over the cracks and using a flexible thin set like flex bond work?
- I’d like to install this over the winter but I’m worried about working temps, shrinkage, etc. I could probably keep the garage around 50 degrees while working and letting everything cure.
- If I have to use an uncoupling membrane would Laticrete’s Strata suffice? I like the idea of letting the floor breathe and this mat allows that. I highly doubt there’s a vapor barrier under the slab and would like things to dry out.
Any advice would be greatly appreciated.
