sorry, it was the spartacote flex system. there is local company with good reviews that is sparta certified installer. going out to talk with them on saturday.

Looks like the Spartacote Quartz or Diamond Topp would be the durable systems that could stand up to a lot of torque from turning wheels, equipment being rolled around, tools dropped, etc. I could not see specifying the Guard or Chip systems for any commercial coating project we would design.

Slab is waaay old.. uhhhh 1930ish?
Its off the basement under the house.. primarily just to park in, or do some bench work on sub-components. Not enough room for anything else.

Other stuff gets done in the larger detached garage in back.

Good luck. Small garages are certainly a challenge! Yours looks quite sharp!

Thx Martin..
its a mess currently with lots of bench top projects going on! There has not been a car parked inside since finished!

Be careful with using penetrating sealers like siloxanes on garage floors. Many of these are intended as waterproofing systems and provide this characteristic by shifting the surface energy of the concrete to prevent water from soaking into the surface (think of water beading up on a newly waxed car). Frequently, good waterproofing materials (hydrophobic) are good attractors for oil based materials (oleophillic). Not a good situation of our cars, many of whom like to leave their personal mark on the garage floor!

Uhm, okay... So what are you saying, exactly? They will keep water from absorbing but will readily absorb oils?

This is pretty standard stuff for application on parking garage decks that do not get waterproofed, as well as concrete-paved bridges. I am happy to get (re)educated here, as I still needs some continuing ed hours...

I went with Rustoleum Epoxyshield Professional. I bought it off Amazon. I used 2 kits for my 2 car garage; one for each coat. It says you only need one coat, but I think you really need two. I wouldn't have been happy with just the one. It has stood up great to all the abuse. It's been several years and still no peeling. I decided to leave out the "confetti," as it's easier to find tiny things when I drop them. Although, it does get slick when wet.

How did you prep the floor. Did you grind or just acid etch?

Anyone try this new one yet?

Good question. I should have mentioned that. I bought the acid etch kit that they sell. I was also doing it on new concrete.
