Benefits of Granite Composite Sink
Incredibly hardwearing, the sturdy granite or granite composite sinks can take a lot of heat, and dropped pots, dinnerware and cutting boards, from a home chef as they move from stove to sink.
Blanco creates Silgranit, a durable patented composite, and composite granite sinks are often known as this brand name, according to Den Garden.
Granite Vs. Granite Composite Sinks
Both styles are very heavy and require extra installation to ensure the cabinetry can handle the weight. Actual pure natural granite sinks are rather rare and expensive. These types of sinks are created from one slab and can be limiting in color, size and shape.
Granite composite has the style and feel of natural stone but it is actually only 80 percent granite with a mix of 20 percent resin. This makes it much more affordable, as well as durable, according to Faucet Guide. The mix of granite and resin allows the sink to be molded into a wide variety of shapes and sizes. It can have different configurations, as well as finishes from high gloss to matte.
The only true drawback to either type of kitchen or bath sink is that it may chip and requires sealing about once a year to keep it in good shape.
Prepping to Repair a Granite Composite Sink
Before you begin, gather painter's tape, small epoxy spatula, fine-grit sandpaper, granite scouring cleaner and composite sink repair epoxy. You can also buy all you need in a simple kit. Blanco Silgranit sink repair kit comes with all you need to return the granite composite sink to its original luster.
Clean the composite sink surface thoroughly. Use a good scouring powder to rub out and shallow scratches. Rinse all of the detergent away and buff the sink dry. If you have any major gouges, use a brush or fine-grade sandpaper to buff them out as well before you continue with the repair.
Go over the surface of the sink and place painter's tape along the edges of the cracks or chips. Make them as flush as possible to control the epoxy. Cover the bottom and sides of the sink with newspaper or plastic sheets, then tape them in place to protect the surface from drips of the repair epoxy.
Composite Sink Crack Repair
Once the sink is prepped, pour the composite sink repair epoxy into the gouges or chips. Spread it into the crack firmly with a plastic spreader. For smaller chips, use the small end of the spatula to swipe the epoxy over the shallow scratch or chip.
A chipped granite sink that has been filled with composite sink repair epoxy needs to dry for a few days to cure the epoxy.
