I would like to install Avaire tile over existing tile which is 9" x 9" so the old grout lines would be in different places than the new tile. Additionalls the old tile is not totally flat but has a wavy texture. Is there some way to determine if it is OK for direct installation or is their a product that should be used to level the surface.
Thanks for any advice you can give,
