I want to lay 6"sq ceramic tile on our Formica backsplash. I will be
using Mapie Mastic to lay the tile but am wondering if the Formica
needs some sort of preparation or not. To me, it would seem that the
Formica would be too slick and not offer a good surface (as is) for
mastic to adhere to. BTW, removing the Formica is NOT an option
according to the Boss Wife!

P.S. Also the option offered in another list of replacing the Boss
Wife is not an option either (grin).

Regards,
