An old, dirty-looking bathroom sink can be a quick turnoff. One look at a dull sink gives anyone the impression that the entire bathroom hasn't been cleaned for a long time. While this might not be true, reglazing your bathroom sink and giving it a new look isn't too difficult. Applying the ordinary cleaning tricks on your bathroom sink will not give it any shine. So if it's a brand-new feel you want to give to your old bathroom sink, achieve your goal by learning how to reglaze it.
Clean surface of the sink with a standard cleaning agent. This removes the initial dirt and prepares the sink for further cleaning.
Eliminate silicone caulking with silicone digester. Get rid of as much caulking as possible because any residue will affect the end result
Scrape the sink with an acid paste. This eliminates any leftover debris. Be careful and wear safety gloves when working with acid.
Apply degreaser on the sink to give it one final cleaning before you start the glazing.
Use plastic or newspaper to mask areas that you do not want to glaze, such as bathroom tiles beneath the sink or on the walls adjacent to it.
Apply epoxy primer to the bathroom sink. If you are using a brush, make even strokes on the sink. For spray primer, hold the sprayer a few feet away. Glaze evenly and don't skip any part of the sink. Let the primer dry.
Spray acrylic-urethane resin to get the glaze you're looking for. Wait 15 to 20 minutes to let the resin settle.
Apply polyurethane coating to the sink for a shiny surface. Once everything is dry, reapply silicone caulking to your sink.
