Chips and dents occur in acrylic bathtubs from dropping shampoo or shaving cream bottles on the tub surface to dropping a hammer or wrench when working on a faucet or drain. Whatever the reason, the chip is normally noticeable and stares at you every time you enter the bathtub. Fortunately, fixing the chip is easy when you know the proper procedure.
Wet the sandpaper and rub the chipped area with circular motions. Try to rub only the chipped area of the tub and not the area surrounding the chip. Add more water to the chip and the sandpaper if the area becomes dried out from rubbing.
Rinse the chipped area with water and dry with a clean rag. Make sure the chipped area is completely dry before applying the epoxy.
Apply the epoxy resin with the applicator from the repair kit. Apply the epoxy until the chip is filled. Wipe away any excess epoxy surrounding the chip with a damp rag. Allow the epoxy to dry for at least 12 hours.
Sand the epoxy gently with a wet/dry sandpaper. Rinse any residue away with cool water. Wipe the area dry with a soft clean cloth.
Apply polish or gel coat from the repair kit with the provided applicator or dab the polish or gel coat onto a soft clean cloth and apply to the epoxy. Allow the coating to dry for 24 hours before using the bathtub.
Most repair kits include sandpaper, but if yours does not, purchase a wet/dry sandpaper with a 1500 grit.
