Ensure that the damaged area and surrounding surface are clean and dry - free of dust, dirt, grease, soap residue, wax and cleaners. Though not necessary, for a stronger bond you can (carefully) rough up the damaged area with the enclosed finishing paper (220 grit aluminum oxide sandpaper). The small cut (1" x 3") allows more selective sanding of small repair areas.
For deep chips and gouges, you should first fill them with Fill-A-Fix before using Porc-A-Fix.
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.
Apply in thin layers, allowing at least one hour drying time between coats. The drying time can be decreased by using a hand held hair dryer on the coolest setting, held at least one foot away from the repair. Use a back and forth fanning motion with the hair dryer - do not hold it stationary over one area.
Dry for 24 hours after the last layer is applied. If any brush marks remain, or if any debris has settled into the repair, sand very lightly after drying to remove these imperfections. You may use the enclosed 220-grit finishing paper, or use additional paper of similar or finer grit as you deem fit.
You may first fine-finish the repaired area with 360-600 grit silicon carbide sandpaper, to save buffing time. If you do, sand just until the glaze is smooth with the surrounding porcelain gently to avoid sanding through the glaze. Note: for many minor repairs, sanding after the final coat may not be necessary.
Then buff the repair and surrounding area with a soft cloth and a bit of automotive polishing compound.
For routine cleaning of the repaired area, use a mild liquid abrasive or dishwashing liquid; we recommend this not only for the repaired area, but for the entire fixture. Do not use harsh chemicals or abrasive cleaners on the repaired area. This will reduce the chance of scratches from surface dirt or abrasion
