Finding a leak beneath the sink can cause a major headache. It is likely that many homeowners will initially assume that the problem is with the plumbing, and the pipes or fixtures are at fault for the pooling of water below. However, a tougher problem to resolve is when the leak is coming directly from the sink.
Not all cracks will cause leaks, but learning how to fix a cracked sink quickly can prevent your sink from getting worse. You would much rather patch the crack than have to replace the entire sink. Fortunately, fixing a crack in a porcelain sink requires only a stop at the hardware store and less than an hour out of your day.
What you will need from the hardware store is a small amount of epoxy specifically made to help fix porcelain, ceramic and enamel surfaces. This will be found in a small kit that contains two vials; one is the catalyst, and the other is the hardener. You might find different colored epoxies so you can use the one that is the best match for your sink.
Before jumping straight to applying the epoxy, you will need to prep the affected area. Using a sponge and soapy water, first scrub the area around the crack. Once it is dry enough, you will then want to use a 400- to 600-grit sandpaper over the damaged area. The sandpaper is used to remove dirt and rust, but also used to roughen up the area to make it easier for the epoxy to stick.
After the area has been prepared, you can mix the two components of the epoxy. When you are comfortable with the color that will provide the best match, take a small brush and fill in the chip with the epoxy. Deeper cracks will require several coats. Finally, allow the epoxy to set.
Even though you have finished with the repair, the sink isn’t quite ready for everyday use. Give the sink and the epoxy 24 hours to make sure that the crack has been properly sealed, and give the sink around seven days to set before you scrub that area.
There are a couple expectations you should know when taking on this project. For instance, it may be difficult to find an appropriate color match for your sink, so even though the crack may be sealed, the fix could stand out more than the crack itself had. One way to test the color match is to apply a few dabs of the mix onto a clear piece of tape and hold it against the sink. From there, you can adjust the tint by either adding more resin or adding more dye.
Also, not all cracks can be saved. If your fix requires more than one repair kit, or if you have found that it needs another repair in the months that follow, consider a replacement. Cosmetic cracks are one thing, but structural cracks are a much bigger problem. For more information on fixing cracks in your sinks, call Kellermeier Plumbing at 616-866-5134.
