After sealing a stone tile surface outdoors, these white cloudy spots appeared within a day or two. They appear more frequently near the grout than the tile, but not exclusively. What caused this, and what can I do to clean it up, if anything?
From my experience, it is excess moisture. The one spot looks like water sat on the sealer before it cured. The remedy is add a bit more sealer to the area, try just enough to dampen the area first on a clean cloth. Make sure it is dry, and stays dry until it cures.
