Rustoleum epoxy sheild

[mechanic12]

Any help would be greatly appreciated. We just purchased a new home an wanted to put Rustoleum epoxyshield on garage floor as we had it in our old house and loved it. So we did put it on the new garage floor about a month ago but would like to put another coat on it because it got some scratches on it when we moved stuff across it to soon. but we do have one more can left.
Just wondering if i could just paint over top since we just did it a month ago????

Best to consult the manufacturer. In lieu of that, you need to create a mechanical bond by de-glossing the surface and wiping it down with a solvent (thinner will do).

Yes, consult with the manufacturer for their specific recomendations on reapplying. Typically you will have to do what Legacy suggests and rough up the existing coating.

But yes, they're right. Scuff sand w/ 120-150 grit then wash the floor to remove sanding dust. Be sure to wait until the floor is completely dry before re-coating.

Could i achieve this by just doing a etching with the solution that comes with the kit?

That will almost certainly not work; etching works by dissolving minerals in the surface of the concrete, leaving a rougher profile. The coating will not react to the etching chemicals in the same way. Mechanical abrasion is going to be required to roughen up the surface. (Just a quick note, since your question makes it sound like you're trying to avoid doing it: scuffing the surface is not a particularly difficult job and goes pretty quick. It's not like you have to sand it down perfectly for hours... just abrade it enough to take the gloss off, then wipe off the dust.)

Epoxy coatings by nature need to be opened up (scratched ) in order to get a mechanical bond between the coats. What this does is open up the surface tension of the coating and gives the new coating an anchor profile to bond to. Thus the reason a chemical etching will not work. Make sure to leave a 1/4 inch feather area around the new coating. This will ensure a good bond.

Good Luck
