How to fix chipped enamel on a sink

When you accidentally drop a heavy pan into a cast iron or steel sink, you're likely to chip the hard enamel surface. I know the sinking feeling, having chipped one myself hardly a year after installation. Puns aside, it's fairly easy and inexpensive to repair chips so they're almost invisible. You can find two-component epoxy (catalyst and hardener) in the adhesive section of most hardware stores and home centers. It's usually available in a variety of colors. If necessary, two colors can be mixed for a more precise match.

First, scrub the chipped area thoroughly with a sponge and soapy water. Then rub 400- to 600-grit “wet-and-dry” sandpaper over the damaged area to remove dirt and rust, as well as rough up the chip so epoxy will stick to it. Next, mix the two epoxy ingredients according to label directions.

Use a wooden matchstick or small brush to fill the chip. If the chip is deep, apply the material in several coats, and don't forget to allow for the drying time specified on the label. Once the repair is complete, wait 24 hours before you use the sink, and don't scrub that area for seven days.

You asked about finding the right color Mica powders like scrap bookers use can be mixed with the epoxy to get what ever color you need. Mix the Mica powder powder in before you add the hardener so that you have time to mix it completely and match the color be sure to mix it in, in small amounts a little goes a long way. . Then add the hardener and follow the directions for applying it. I keep track of how much color i added so that if i need to fix another chip I already know how much to use. I write it down and put the mica powder into an envelop and mark it. For example " master bath sink repair" and in that envelop I have the brand of my fixtures when I bought them and a part # and maybe a replacement washers for the sink and tub and or shower. Oh and a photo copy of any parts receipts so I can use the warranty if needed and the warranty info. Then use duct tape to tape it to the inside side of the cabinet usually on the right as I'm right handed or the inside of the door and high enough that if there is a leak it wont get to the info.

I could use some advice on where to find epoxy for older sinks, bath tubs and toilets because the colors are usually not available. For instance, my bathroom sink and toilet a beige color with a rosey undertone. I have been unable to find anything to match and mixing is all but impossible because the places I have been to don't carry the colors I would need to use as a mix.
Is there any place you know of that specializes in the older colors?
Thanks for your help.
