Does anyone have a concrete bathroom or kitchen?
 

If so, what sealer did you use for it?

my parents had some concrete countertops done and also a floor in the bathroom. not sure which got which but one had xylexin and then they used some bee's wax sealer made for concrete. i had to call my mother to ask, she knew the names but not which went where. i would presume the bees wax went on the countertops though.

Dude u need some epoxy sealing paint. Or other epoxy based sealer, and sand on the bottom for grip if you don't want to bust your ass.

From years of experience with warehouse floors ... Pick a water-based sealer. They wear out quicker but are easier to apply and you don't (in most cases) need to acid etch the concrete.

There is no bigger nightmare than seeing your sealer separate and remain tacky because it had a bad reaction to existing products.

With water-based you can scrub with regular soap, rinse well, apply when dry on a regular basis.

There are some very trick epoxy finishes you might want to research if color is an issue.
