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.

    No lumps...or at least a dark speck. – Jack May 25 '17 at 2:20
  • Definitely not birds. Not obvious from this one photo, I agree, but looking at some of the other spots it's quite obvious. – Gregable May 25 '17 at 21:18
