I'm in the process of painting my concrete garage floor, and wondering if it's worth all the effort. Hopefully it'll be durable but I have my doubts. I'm using the behr stuff from homecheapo, ran about 80 bucks and it's a 4 step process 1. sweep and wash the floor 2. use the degreaser, scrub and wash the floor 3. use the acid etcher/rust remover, scrub and wash the floor 4. apply primer (actually a thin clear liquid, I thought it would be a paint, I'm waiting for this to dry for 24 hours) 5. paint with latex paint, they call it a one part epoxy but I'm sure it's just a paint. Has anyone used the same product? has it held up to oil drips? tires? dropping stuff on it? I've seen painted garage floors that look great, and some that seem to chip and kind of fade away. Hopefully this will last after the time and expense I have in it.
