Grace Bondera self-adhesive tile underlayment lets you quickly install tile over a variety of finished surfaces, with no mortar or mastic. Painted walls, laminate countertops, and even tiled surfaces can be covered (or re-covered) with tile and grouted on the same day. Wall and countertop versions are available in 10-square-foot rolls for $39 and $32 respectively. Special edge tape is used to hold the vertical tiles at the edge of the countertop, but there must be a ledger strip underneath the tiles for support. W.R. Grace, 888/862-8738,
