Yes, you can use Polyaspartic, works down to -20F. I usually get it from these guys. http://www.slide-lok.com/products/garage-floor.php?top_nav Its super solid stuff.

Hey Cosmic, I think Stryker might have nailed it, looks like tire shine. I would degrease it really well, acid wont remove the silicone thats in the tire shine. Try putting some heavy duty degreaser on it and scrub it with a course brush a couple of times, rinsing in between, basically until...

Use Polyaspartic, you can apply it and it will still dry down to -20F.

Technology is pretty cool. Yep that looks good, its not beading up on the concrete and you can see it changes the color of the concrete quickly meaning the concretes opened up pretty good ready for a coat, so from what I can tell looks like its good to go. Please tell me after your efforts your...

Mfive, don't make the mix too strong, about 1 part acid to 4 parts water is good, it should fizz like your getting, keep in on there for about 10 - 15 mins, lightly spray water around to keep it wet not water it down. I agree etching never will get the cement down to a 120 grit finish, the best...

I haven't tried them, but I do regularly use Polyaspartic from Slide-Lok and its a super solid product, you won't have any fade problems with the Polyaspartic. Its definitely the best choice, it will cost more than epoxy but well worth it. If you do it yourself you may want to check prices from...

Hey Leon, Hows the floor going? Have the guys started yet?

Again I agree with Edger. The concrete will just smooth out the grit on the sand paper instead of etching the concrete surface, diamond grinding is the best, and if the guy is a bit amateur he could leave track marks with a shot blaster. If he doesn't have a diamond grinder, he could rent one...

I agree with Edgar, They definitely need to grind off that coating, and yes the edges will come off with a edger grinder fitted with a diamond blade, not a sander. They may need to use a separate head on the floor grinder to strip the old (or should I say failed) epoxy off first then diamond...
