I want to do a mosaic on my bath room counter which is formica. Will the mud base used for tile stick to formica? Is there an alternative or is it a lost cause?:confused:

Scratch the formica up really well with sandpaper. This will help the adheasive adhere. Use a premixed tile adheasive. I use Mapei Premix thinset adhesive. Wait a day then use a nonsanded grout.
