Sometimes reglazing sink surfaces is the only way to save an unsightly sink in your bathroom. While normal cleaning can remove stains, and it is usually possible to remove even the worst discoloration with a little bit of effort and the right cleaning supplies, the truth is that some sinks are dirty beyond repair. In this situation, reglazing the sink is the best solution. Fortunately, reglazing a sink is a task that any amateur can tackle with the proper supplies and techniques. What follows should help you fix your sink and leave it looking as good as new once you are finished.
Step 1 - Prepare the Sink
While this might go without saying, it does no good to simply seal in dirt and grime. Before you reglaze your sink, you must clean it as well as you possibly can. Use whatever cleaning supplies you normally use to clean your sink, which will vary based on the type of material it is made out of.
Additionally, once you have completed this, you will have to remove any silicone caulk that is present from your sink. You can use a silicone digester to do this quickly and thoroughly.
Third, you should use an acid paste to clean the sink. This will thoroughly remove any unwanted materials that your previous cleanings have left behind.
Finish up with a degreaser, and you will be ready to reglaze your sink under the best conditions possible, which will increase the chances of the job going smoothly.
Step 2 - Protect the Surrounding Area
You may not want to reglaze your entire sink, and you definitely do not want to affect the surrounding area. Any areas that you want to be sure to protect, you should cover in plastic sheets. Be sure to cover the floor as well as nearby walls and fixtures.
Step 3 - Prime the Sink
When priming your sink, use epoxy primer. It is your choice whether you would prefer to use a paintbrush or spray primer. If you choose spray primer, make sure to hold the spray can relatively far from the sink, and make even passes that do not allow paint to pool or drip. If, on the other hand, you choose to use a brush, be sure that you blend together any streaks or areas that receive too much paint. Once you are finished, wait for the primer to dry. While this amount of time will vary between brands of primer, the manufacturer's instructions will probably give you a good idea of how long this should take.
Step 4 - Reglaze the Sink
At this point, you are ready to glaze your sink. Use spray-on acrylic-urethane resin, using the same techniques you would for spray primer. Finish up with polyurethane coating.
Step 5 - Finish the Job
After your sink is reglazed, reapply your caulk. Use a caulk gun to do this. Hold it at an angle and apply the caulk as evenly as possible while pulling the tip of the gun away to avoid spreading it around. Once you have done this, use your finger to push the caulk into the joint and remove any extra caulk.
