What prep work you have to do?
First I swept the entire garage out at least twice. Its unbelievable how much dirt can accumulate, as well as salt from the roads in the winter and so forth. Then I rinsed it out twice with a hose and used a synthetic push broom to break up any extra dirt as well as push the standing water out of the garage. After I was satisfied with that level of clean, I generously applied a heavy duty (Behr) degreaser and scrubbed the hell out of the entire surface, going over any oil and grease spots with even more degreaser. After that was all soaped up, I let it sit for a while and scrubbed it again. It's crazy how much oil, tar and grease came up. It took two full rinses with a hose and push broom again before all of that stuff was washed off the concrete. Then came the etching compound (basically chemical abrasive for concrete). It eats away the surface of the concrete so the paint-epoxy mix sticks better. After that has worked it's magic, it required two more full rinses to wash it all out.
***CAUTION***
If that stuff runs down your black top driveway and you don't rinse it off quickly, you're gonna have a bad time (i.e. I will be resealing the driveway soon).
It took fooorrrrevvvveeerrr for the garage to dry out, even with the doors open and a fan running. It needs to be as dry as possible before applying the paint. After applying the paint-epoxy mix and sprinkling the colored chips everywhere, it usually takes 3 full days to dry/cure. You can walk on it after 24 hours or so, but shouldn't drive on it for at least 72 hours.
Yeah what he said!
That looks really clean!
Thanks!!!
