Cure for curling vinyl

Photo 1: Cur out the curled vinyl

Slice alongside the curled edge of vinyl flooring with a utility knife. Then peel off the thin strip of vinyl and clean out any dirt or old caulk.

Photo 2: Attach a threshold

Spread a bead of silicone caulk on the back of the threshold and along the base of the shower.

Photo 3: Clamp the threshold

Press the threshold against the shower base. If there are gaps, use clamps to hold the threshold tight until the caulk sets.

When water gets under the sheet vinyl along the edge of a shower or tub and the vinyl starts to curl, no amount of caulk can hide the problem. But here’s an easy fix that also looks great. Buy a solid-surface threshold strip (Corian is one brand available) at a home center or tile shop. They’re available in various lengths and thicknesses; the one shown is 1/2 in. thick. The solid-surface material cuts like wood so you can use a handsaw or miter saw to cut the piece to the right length. Photos 1 – 3 show how to complete the repair.
