How to Fix a Salt-Damaged Garage Floor

  • Transcript

    LESLIE: Alright. Now we’ve got Tom in Wisconsin on the line who needs some help with a garage floor. Tell us what’s going on.

    TOM IN WISCONSIN: Well, my wife – with her minivan – she comes in out of the snowstorm. I’ve got snow in now; I’ve got salt and everything out. And when the salt drips on the garage floor, it bubbles up. And it pops.

    TOM: OK.

    TOM IN WISCONSIN: And now it looks bad. I was wondering if there was a – something I can patch it with that’ll withstand the garage floor.

    LESLIE: Now, what’s already on there that’s bubbling up? Do you have some sort of epoxy coating or is it just the concrete? Is it staying because of the salt?

    TOM IN WISCONSIN: I think it’s just the concrete. When they built my concrete floor, the builders, they put a real high polish on it. So it’s real, real smooth; it’s real fine.

    TOM: OK. But there’s no other coating on it except for the …

    LESLIE: Or sealant?

    TOM: OK.

    TOM IN WISCONSIN: Yeah. No, it’s just the concrete.

    TOM: Alright. Well, I think the best solution there would be to use one of the new epoxy products. They adhere very well to the concrete and that’s the key is the adherence issue – the adhesion issue, I should say. And you can also add a color flake into them and that gives you some texture, helps to hide the dirt and you can even put a gloss coat on top of that.

    Two-part product. Comes with a cleaner that you mix up first to get the surface ready to accept the epoxy. Then you apply the epoxy, wait a couple of days to get it nice and hard and you’re good to go.

    TOM IN WISCONSIN: Oh, awesome. And where the – because it always seems to be one spot. Will that bubble up after that again?

    TOM: No. It’ll just sit on top and dry to sort of that white, crusty surface. But you can then wash down the floor and get rid of it.

    TOM IN WISCONSIN: Oh, awesome. How about outside, for external? Will that work?

    TOM: Well, there are epoxy products that work on exposed concrete surfaces, as well. But you might be just a little more careful with those because you don’t want it to get too slippery.

    TOM IN WISCONSIN: OK. Awesome.

    TOM: Alright?

    TOM IN WISCONSIN: Well, thank you very much.

    TOM: You’re welcome. Good luck with that project. Thanks so much for calling us at 888-MONEY-PIT.
