    Slate Sealer

    I have a salt water pool. Can someone please recomend what is the best product to seal the slate coping and the tile at the water line which is also half submerged in the water? Originally the builder used a water based sealer which turned white below water line and flaked off every where else. Your help will be greatly appreciated.

    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.

    I'm NOT an expert by any means but any sealer, water based or solvent based, is going to turn white below the water line if it isn't 100% dry for 3-7 days. I have to wait for a 5-7 day dry spell to seal my stamped concrete pool deck every year but I don't seal below the water line.
    Last year I had no problem finding the 5-7 day dry time as we were in a drought. This year may be more challenging 8) ...

    Can someone else chime in that knows slate and/or rock sealants ?
