I epoxy'ed my shop (54'x46'
PIX) as soon as the concrete was 30 days old. I acid washed and let it dry then rolled it on. Mine has not lifted, or had any issues. I used Rust-Oleum EPOXYSHIELD Professional Floor Coating kit, but did not add the speckle flakes, but did use the anti-slip additive.
If I did it again, I would:
- Put it on a little heaver. My epoxy went further than the label said, so I had a lighter than recommended coating. I'd do it by pouring it out and spreading it with a broom and roller.
- Add a clear coat of epoxy on top of the color coat to add UV protection and have a tougher yet coating.
- If I cleared it, I would go ahead and add the speckle, as the clear coat will seal it in place.
