Porcelain Chip Filler

Fill-A-Fix fills deep chips, cracks and gouges in porcelain prior to finish glazing with Porc-A-Fix, in cases when the glaze alone is not enough to fill the damage.

This kit is easy to use - simply apply, let dry, and sand smooth. Each Fill-A-Fix kit contains sufficient material to make one to three repairs, depending on the size and depth of damage.

Please read all directions and warnings prior to use.

Product Precautions


  • Contains nitrocellulose putty.
  • Do not take internally. Avoid eye and skin contact. Avoid prolonged exposure to vapors.
  • Keep bottle well closed (when not in use) and out of the reach of children.
  • Until dry, Fill-A-Fix is flammable - store and use away from heat, sparks or open flames.
  • Use in a well ventilated area.
  • Wear protective glasses and rubber or neoprene gloves if possible, to reduce chances of eye and skin contact. The filler is an eye irritant and may cause skin irritation or rash with prolonged contact.


  • INGESTION: Drink one or two glasses of water to dilute. Do not induce vomiting unless directed by a physician. Get medical attention immediately.
  • INHALATION: Remove to fresh air. Get medical attention if breathing problems persist.
  • EYE CONTACT: If you get Fill-A-Fix in your eyes, immediately flush eyes with large amounts of fresh warm water for fifteen minutes. Get medical attention.
  • SKIN CONTACT: Remove contaminated clothing. Wash affected skin thoroughly with warm water and soap. Rinse thoroughly with fresh warm water for at least five minutes or until all residue is removed. Get medical attention if irritation persists. Wash affected clothing before reuse.


  • Fill-A-Fix should not need to be thinned for use, but you can thin it or clean up residue with acetone.
  • Acetone (the primary ingredient in nail polish remover) is flammable, can burn or irritate skin, and can be harmful if ingested or inhaled. Follow all appropriate cautions suggested by its manufacturer.

Before You Start

  • The Fill-A-Fix base filler is designed to fill deep chips and gouges, before applying
    Porc-A-Fix as a top coat. Porc-A-Fix will match the color of your fixture to complete the repair.

Application Instructions


  • Ensure that the damaged area and surrounding surface are clean - free of dust, dirt, grease, soap residue, wax or cleaners.
  • To make sure this area is totally dry, carefully wipe just the repair area with a small amount of acetone after cleaning.


    One 30-second video or 5-6 still photos showing can opening and stirring, application with stick, 30 minutes expiring on clock, reapplication.

    Shake the bottle for at least 30 seconds and allow it to sit for at least one minute prior to opening the cap. This will allow excess material on the cap or brush to roll back into the bottle. Open the cap carefully, making sure to wipe off any excess material on the lip of the bottle with a cloth.

    Fill the damaged area with thin, even coats, allowing 15-30 minutes of drying time between each coat. Fill the damage to just slightly below the original porcelain surface, as this will allow for a smooth and level application of the Porc-A-Fix top coat. Do not try to fill deep gouges in one coat. It is not necessary to sand in-between coats.

    One 30-second video or 3-4 still photos showing 48-hrs expiring on clock; successive sanding, ready to glaze.

    Dry the final fill coat thoroughly before sanding. Without forced drying, typically allow at least 48 hours of final open-air drying time (the filler may dry in as little as 24 hours in low humidity conditions).

    Sand the filled area, once completely dry. Use the 220 grit sandpaper to remove any surface imperfections and ensure that the fill is slightly below the porcelain surface to allow for the glaze application.

    Finish the repair with Porc-A-Fix.
