Epoky over epoxy over epoxy????

[tjf]

First off, I just foudn this forum and really enjoy it. I have been into cars my whole life. I just graduated law school and bought my first house... the decision was based largely on the garage!!!! I have put alot of work into the garage and it is nearly ready to debut on this forum, but first I need to fix one small issue:

The first thing I did was epoxy the floor with the Rust-Oleum kit form Lowes. It looks really good, but I was in a hurry so I didnt patch some of the divots in the concrete (The house is 40 yeasr old). The paint has stayed down very well, but now I want to patch the holes, repaint it, and top it with Rust-Oleum's clear coat for that extra clean and shiny look.

My question: Can I put a concrete filler ON TOP of the existing epoxy??? Can I then put another coat of epoxy over the existing layer that has been down for almost 6 months now??? Will the coclor flakes on the existing coat leave raised areas in the new coat(s) ???

Thanks for the info!

This is something you should probably call Rustoleum about.

They do make their own brand of patch filler - which would probably work. I know they say there is some sort of "window" of time that you can put a coat on top of the previous coat. If anything, you will probably have to scuff sand the current coat (after patching) to provide for adhesion by the new top coat. I would probably put down new flakes to be safe.

You should be able to enact repairs and recoat as you want with some preparation of the coating. Scuff sand the existing coating with a coarse sand paper around 60-80 grit to create a profile. Remove the debris. Use the recommended epoxy patching materials in the needed areas. I tend to stay away from concrete or cement patches as they are very rigid and can pop loose. I usually allow the epoxy patch to cure and then scuff them up as well. The patching material is usually smoother than the concrete and the coating, so this helps it blend in more. The sanding will usually a lot of the flakes, although any that are left can create a raised profile in the new coating. It would be best to re-flake it as you apply the new color coat. Allow it to cure as recommended and top with the clear coat. Make sure when sanding scuff and scratch the entire surface, it you do not create a strong enoug profile the new coating will not get the proper mechanical bond to the existing one, and could de-laminate over time/use.
Good luck with your project, you should be OK.
