    Tiling over an exsisting concrete shower floor
    Hello and Happy New Year,

    Here is our problem. We remodeled a bathroom and tiled the shower walls and floor.
    The exsisting shower base was painted concrete. We sanded the concrete, then tiled,using a grout with latex. A couple weeks after, we noticed tile and grout coming up.
    When we pulled up all the tile we noticed there was a lot of moisture under the tile around the drain and less and less moisture as we moved away from the drain toward shower walls.
    We would like to retile the shower floor, but now we are not sure what caused the moisture problem. We never had a problem with the old floor and drain.

    What do we need to do before retiling our shower floor? I've looked through many forums, but haven't found anything that answers this specific problem. Hoping someone here knows.

    Thank you,
    Jmaire

    Grind the floor a bit to roughen it up a bit, then tile it again, but this time where the drain is purchase a extension that caps the old drain mouth over the new floor. Use silicone on ALL your corners as well
