I am expanding a small toilet in my basement to a 5 X 8 foot bathroom. I had to have the commode drain moved and then replace about 10 square feet of concrete, which I did with a Henry's Concrete Repair product. I sanded it to try and smooth it out. During this time I had gone to Lowe's to get something to prep the floor to put down peel-and-stick vinyl plank flooring. They gave me Seal Krete Lockdown Concrete Bonding Primer. Is that suitable for putting this tile on, or do I need to do something else?

Thank you.

You're starting out right. Get that floor as smooth as you can. An underlayment compound may be needed. Sanding helps. A primer can never hurt.

I admittedly have no experience with any of the new generation of peel and stick products. In the past whenever I had to deal with peel and stick anything (which I always try to avoid) I would apply adhesive to the floor first. Just as I would if it weren't peel and stick. In your case a pressure sensitive would probably be best. Let it dry to the touch before installing tile. Be sure to press the tiles firmly in place, preferably with a roller.

Make sure the concrete patch is cured. I don't know much about newer peel and stick either, but green concrete would destroy the old stuff.
At the very least laying over a wet slab would risk destruction of the adhesive--------complete bond failure. Actual damage to the material generally would come from alkaline salts brought up with the moisture.
