Our house has old formica countertops in the kitchen. We'd like to have tiled countertops, and to save costs were wondering if we can reuse the old formica countertops. Would it be possible to either treat the old formica and adhere the tile to the existing top, or to remove the surface plastic and reuse the wood. If we can do either one of these, what are the steps we need to take? Thank you for advice!
