A few people have found this site by asking if they can use Quikrete High Gloss Sealer over epoxy garage floor paint, so I figured I would do some research and find out.  As is the norm with Quikrete, you have to be very specific about the name of the product.  Assume nothing!

Quikrete High Gloss Sealer

This is a water based, waterproof sealer that Quikrete says is intended for use on both painted and garage floors, so it stand to reason that it should be fine on painted garage floors.  It can also be used on bare concrete garage floors, and even masonry, brick, aggregate, stone, and pavers.  Hah, this means you could put it on a brick house and end up with a waxed looking house.  Anyway, since this is a sealant, you might not want to apply it to concrete that isn’t etched since you’ll probably end up with a pretty slick garage floor.

Quikrete Wet Look High Gloss Sealer

Another water based sealer, but a different product.  This one does not specifically mention one way or the other if it should be used on paint, but Quikrete does say that they don’t recommend it for use on garage flooring.  Upon deeper investigation into the product specifications, it does say “Previously sealed surfaces must be porous…”, which an epoxy garage floor coating is most certainly not.  So the verdict is, no, Quikrete Wet Look High Gloss Sealer should not be used on garage floors, painted or otherwise.

Quikrete Etching Stain High Gloss Sealer

I’m being dead serious with these product names.  In an age where people find much of their information on the internet, they couldn’t have made these different products harder to search for, using the same three words in every title.  Quikrete says that this product can be used on your garage floor.  They do not specifically mention painted surfaces, but the product information does say, “Avoid using this product on non-porous, sealed surfaces”.  That makes it pretty clear that, no, you cannot use this product over epoxy garage floor paint.  It also says that, as the title indicates, it is meant for use on floors that have been treated with Quikrete Etching Stain, so it would probably create a rather slick surface.

So, in summary, if your garage floor is painted or unpainted, you’ll want to look for Quikrete High Gloss Sealer, and be absolutely sure there are no other words in that title.
