Fibreglass baths last a long time. However, chips can occur in the surface of the bath. These chips detract from the overall look of the bath, making a newer bath appear older than it is. Chips also collect soap scum and dirt, which is unappealing. Too many chips weaken the structure of the bath and eventually leads to leaks. Repairs are fairly easy and require just a little patience to complete.

- Razor blade
- Fibreglass bath repair compound
- Spreading trowel
- Sandpaper, 200-grit wet or 80-grit dry
Clean the bath with bath cleaner and a bristle brush. Remove all dirt, soap scum and stains. This will reveal the chips in the surface. Repair them all at the same time for maximum effectiveness.
Remove any burrs and flakes from around the chip area in the bath, using a small razor, until the surface around the chip is smooth and flake free.
Mix the fibreglass bath repair gel with the hardener in a plastic container. Follow your repair kit instructions for the appropriate mixing ratios.
Apply the repair compound to the surface of the chip with a spreading trowel. Fill the entire chip with compound, then scrape away the excess with the flat edge of the trowel. Let the compound dry completely. Dry times will vary. Consult the documentation for an estimate of your drying time.
Lightly sand the surface area of the dried compound with 200-grit wet sandpaper or 80-grit dry sandpaper. Only sand the filled area, do not sand the entire bath.
Apply a fibreglass primer to the repair once it is completely dry. Allow this to dry as indicated on the label. Once the primer is dry, apply a single coat of fibreglass paint that matches your bath's surface colour to the repair, using a spray can or spray gun. You must find a fibreglass paint that matches your bath's surface colour to blend the repair. A gel coat, a type of fibreglass paint that contains epoxy and pigment, will give a shiny surface. Fibreglass paints and gel coats are sold at hardware shops, boat shops and speciality paint shops.
Tips and warnings
- Use a hair dryer to accelerate the repair compound drying process.
- Some fibreglass repair kits include a top coat of fibreglass paint or gel coat.
- To completely blend the repair you may also add pigment to the epoxy repair material so it matches the colour of the bath. If you take this step, painting may not be necessary.
