Big_D,

I also need to re-attach a couple of pieces of tile along the top edge of our spa (attached to the pool). We've tried a number of types of sanded grout, but the tiles keep re-popping out.

Do you or anyone else have any specific recommendations for what we can use, and that will "stick"?

Also, is just the grout enough, or are we suppose to use some kind of adhesive to glue the tile into place and THEN grout?

Thanks,
Jim
