Garage Floor Epoxy Screw UP :(

[Frisson]

So I finally painted the garage floor with one of those DIY kits.

I cleaned the HECK out of the floor, etched it twice, and followed the directions on the kit when laying it down.

As it dries I can see NOTICABLE differences in color/gloss... I have no idea what I did worng?

ANyoen else have this happen?

Can I paint on top the epoxy or do I need to scrap it off and start over?

Thanks for your help.

What product did you use?

I haven't done a floor in epoxy, but I've read a lot of posts here about it. Most of the users claim the stuff looks like you describe on the first coat, but the coverage/consistency is much improved on the second.

Have you put down multiple coats? Did you have enough product (ie: it's not too thinly applied)?

I'm sure someone with more experience will chime in soon.

Thanks for the info. I used the rest-oleum garage kit. I have not done mutiple coats.

Can i paint over the dried epoxy that is down? (To even it out?).. Or does it have to be painted onto concrete?

I called Rustoleum before doing mine. They said that the second coat must be applied within 24 hours, after that you'll have to "scuff" the surface to allow a mechanical bond.

I think what might have happened in your case is possibly "overworking" the epoxy. As soon as the epoxy starts to "cure" if you keep rolling it will dull the surface. I have one spot in my garage where I did this...

Best bet is to call Rustoleum and present your question.

Good luck,

Jim

The porosity of the concrete can be the culprit. The rougher or more porous an area is, the more product it will absorb and can cause an un-even finish. Excess humidity during application can cause epoxies to "blush" or go dull. The epoxy absorbs the excess moiture from the air and tries to incorporate it, causing an un-even finish as it cures. If you rolled over any areas again using more product, that can cause a difference in sheen as well. The more product you have, the greater the sheen will be.

The best way to help ensure adhesion would be to scuff sand the coating with a 60-80 grit sand paper to create a profile. Remove the debris and apply another coat. Be conscious of the weather and your application technique for best results.
Just my $.02

over working will cause that more than pouriosity of concrete.
my first floor did that and fixed it with an application of the clear.
(I just laid it on and was careful not to overwork the clear.)
rustoleum got that too.
btw did you use the proffesional grade epoxy from rustoleum?
