Epoxy over epoxy prep question and advice...

[dr3x]

Hi. Long time lurker/reader.

Short: located in Fl. Bought a home with a prefinished epoxy floor.

Have a single car garage whose floor is want to change.

It was finished with epoxy and sprinkles.

I want to do a solid or metallic polyurethane finish.

What type of surface prep is needed?

Would then clear coat. Currently going to be more workshop than garage but would like to be able to park car with hot wide tires on it to from time to time.

Any advice is appreciated!!

Probably the best way would be to rent a big floor sander and go at it. Then pressure wash (with chemicals) the **** out of it. And pressure wash it again....

Do your research and get a HIGH quality floor paint. They are out there, so be prepared to spend some $$$ to get the best stuff you can.

I don't know how it is in the Sunshine State, but up hear in the $#1tMitt, salt and road grime absolutely kill epoxy coatings over time. I did mine probably 15+ years ago, and it's showing noticeable wear in the area where the wife parks her car.

Maybe look into a commercial company to do it. Yeah, it might be a bit pricey, but you 'should' get some sort of guarantee out of it.

Degrease, sand the surface with 120 grit sandpaper, vacuum, and then do a chemical wipe with denatured alcohol on a microfiber mop pad. After that, you are ready for your application of choice.

Metallic coatings consist of a dark epoxy primer, 100% solids epoxy with the metallic additive, and then a high performance clear coat of polyurea, polyaspartic, or polyurethane. They look great, but I wouldn't recommend it for workshop. The darker colors of metallics show every bit of dust and highlight the scratches. They are best for showroom type of garages and indoors.

Thanks Shea. When I meant workshop I meant temporary office/video production mancave garage that will be eventually used again as a garage for a sportscar... which is parked outside since the kids and wife need the other 2.5 car garage...

I didn't think the whole thing had to be ground down. Any system advice?

I have found in my area that I usually pay 2x-3x job is worth due to construction business really amped up, and the surcharge cost of quoting in a gated community makes it hardly worthwhile to hire someone who will not do it right to begin with....
