Do-it-Yourself Acrylic Tub & Shower Repair

Scrape any loose, discolored or damaged caulk from around the surround with a utility and putty knife. Try not to scratch up the surface. If you can get a hold of the end of a strip of caulk, you can often pull the entire strip up without much scraping.

Remove the caulk from any loose surround seams and gently pull the surround pieces down toward the bathtub. Fit a tube of silicone adhesive into a caulking gun and apply additional glue to the back of the surround. Press it firmly to the wall and allow it to dry fully before continuing.

Follow the directions in the patch kit for the best results. Run a utility knife over the area to be patched to create a V-shaped gouge, but be careful not to penetrate the surface of the acrylic any further than necessary. Run sandpaper over the area to smooth the surface, then apply the putty to the area. Create a slightly raised section of putty over the gouge and allow it to dry according to package directions. Sand the area once more, then apply the polishing compound and buff the area with a soft cloth.

Reapply a bead of caulk around any edges or seams. Smooth the bead with a putty knife, your finger or a wet rag and allow to dry before introducing water to the tub.
