Fixing sweaty shop floor?

[yomama'sbuick]

I have a problem with a concrete floor that tends to sweat real bad in hot and humid weather. Could I apply a floor coating to prevent this? Any ideas to fix this would be welcome. :anbet: TIA

The moisture is coming up from what's under the concrete, putting a coating over it will eventually come off too. My buddy's garage is like this. He has tried all sorts of paints, sealers etc...he said the ground below it just gives off too much moisture. He should of put a moisture barrier down before the floor was poured..

Yeah that's what I thought too. The floor was poured 15yrs ago and I'm getting tired of the moisture rusting my stuff. I might try some sort of coating that may help with traction when wet. Thank's anyhow.

Try a product from UGL called Drylock. Etch the concrete with muriatic acid and allow it to dry thoroughly. Do not apply this coating if the concrete is moist. The success of Drylock depends on it's ability to penetrate the substrate (concrete). It must be dry for this to happen. Then lay on the Drylock until the concrete is saturated and roll up or mop up the excess. DO NOT allow any of the coating to dry on top of the concrete. Only the amount that penetrates should be left when you are done. When the Drylock cures for 8-12 hrs you can topcoat it with a latex or oil based driveway coating. Do not use a solvent based coating such as H&C or Tuf-Top concrete stain that uses xylene as a reducer. This stuff will soften the Drylock and ruin your floor. Don't let the dummy behind the counter tell you that a solvent based coating will work better. It won't work at all in your case. Hydrostatic pressure will push it away from the concrete and make a spotted flaky mess.
