Polished Concrete Floor and Moisture

[Jsf721]

I currently have an epoxy coating on my garage.

In less than 5 years I have a minor moisture making a mess in my epoxy. I am getting small drops of amber liquid Pushing up and making a mess.

If I polish the concrete and use densifier will this be OK?

Thinking of investing in the diamabrush polishing system? Hopefully I can use it and sell all but the finest maintenance discs.

or will I have the same issue? I have a gray water based paint on for years without an issue.

Thanks,

Has something changed with your drainage since the time of the paint?

Work on the drainage first.

When I considered epoxy coating for my basement floor I found that epoxy was not recommended for old basement floors or other areas below grade (which often have moisture under the floor), since ground water will try to come up through the concrete and it will eventually screw up the epoxy.

Is there good drainage around and under the floor to keep it dry, or is it possible that water is coming under it from one side or the other? My understanding is that concrete remains somewhat porous forever, so you need to make sure it has plastic or other sealing material on the bottom to keep the ground moisture away from it.

Depends what the "amber liquid" is.

If your floor has oil in it, the stuff will continue to rise to the surface. How much will rise to the top? Depends on how much is in your concrete - two ounces? two gallons? two drums?
I've seen production facilities try to polish floors, but there is so much cutting oil deep in the concrete, it will ooze and seep out for the next ten or twenty years. They're wasting their money at that point; even the best degreasers can only penetrate so far into a floor which has been soaked with oil for the past 15 years.

You could grind off and polish. However, you may get some mineral salts being deposited on the surface if this is moisture. Moisture is not usually amber.

Are you sub-terannean?

If you are having this issue, best would be to put on a sealer which is breathable. Contact us via email for tech data and such for the products we recommend.
