How long will it take for Limestone to Dry from being wet, and will the dark spots go away?

QUESTION

THE QUESTIONS AND ANSWERS ARE AWESOME THEREFORE MY QUESTION IS HOW LONG WILL IT TAKE FOR LIMESTONE TO DRY I HAD A PIPE LEAK IN ONE OF THE UNITS AND THE FLOOR GOT THE LIMESTONE FLOOR GOT WET FROM BENEATH, NOW I SEE DARK SPOTS WILL THEY GO AWAY AS IT DRYOUT?

ANSWER

ANSWER - There are 3 subcategories of limestone per ASTM C568.   Their physical properties vary from being vary porous to very low absorbing.

How fast the limestone will dry depends on how absorbing it is, how thick it is, and whether there is underlying moisture that perpetuates the dampness, and what is the temperature and humidity of the area.  If the stone was only temporarily wet and the leak was repaired, then I  would expect it to dry within a week assuming the temperature was 70 degrees F or better and humidity wasn't high.

Sometimes some stones will get damp for an extended time and mineral migration might cause some staining.  This can normally be remediated by having a stone restoration company clean and seal the floor.
