Not to be confused with solid granite, granite composite is an engineered blend of crushed quartz, stone dust, and acrylic resins. The result is a highly durable, low-maintenance, stone-like material that is a bit heavier than solid granite, and beyond fit for the challenge of handling your everyday demands. It’s commonly used to manufacture top-quality kitchen sinks, but you may also find countertops in this resilient, man-made material.
Being a manufactured material, i.e. one that isn’t naturally sourced, granite composite countertops and sinks can be created and offered in a wide range of colors. An inherent advantage is that the finish of the product is more uniform than natural stone would be, making it easy to coordinate with other accents in your space. Here are some common colors of granite composite products:
When it comes to kitchen sinks, the resiliency of composite granite is unmatched. It’s resistant to virtually all types of damage including scratches, chips, stains, and burns. It can withstand the impact of accidental drops and blunt force, which isn’t always the case with other sink materials.
Heat Resistant: Withstands temperatures of over 500 degrees Fahrenheit. Hot pots and pans won’t leave any burn marks behind, and it’ll never fade or discolor.
Stain Resistant: Unlike natural granite, this non-porous material requires no sealing and will keep from staining by design.
Chip & Scratch Resistant: Tough enough to withstand the most laboring of tasks. The hard, dense surface will prevent chips, scratches, scuffs, and cracking.
Consistent: While solid granite is irregular by nature, granite composite offers a similar look with a consistent thickness, shape, and size from product to product.
Malleable: It can be formed into any shape or any style, which is why some granite composite sinks feature integrated drain boards or have pre-drilled faucet holes.
Sanitary: Thanks to its non-porous nature, food and bacteria have no crevices to get stuck in, making this material among the most sanitary options available.
Affordable: Get the look and feel of stone at a fraction of the price.
Hailed for their durability and matte finish, granite composite sinks are popular in today’s busiest kitchens. And since it’s such a versatile material, it can be formed into just about any style or configuration. Whether you’re looking for a single bowl or a double bowl, drop-in or undermount, or even a granite composite farmhouse sink, you’ll have no trouble finding one that fits your needs.
One of the great benefits of a granite composite sink is how simple it is to clean and maintain. Rinse after every use to wash away standing liquids and food particles—this is essential to avoid stains and limescale buildup. For daily cleaning, use a soft cloth and mild liquid detergent. Refrain from using heavy detergents, abrasive substances, or metal scrub pads, as these could damage the surface.
Deeper cleans should be viewed as a last resort, but accidents do happen. Most stains can be removed by filling the sink with a highly diluted organic cleaner and letting it soak overnight. Rinse with warm water, then wipe dry with a soft cloth.
For oil-based stains such as paint, remove immediately with a cloth that’s dampened with denatured alcohol.
For lime buildup, cover the bottom of the sink with a solution comprised of vinegar and water and let it soak for several hours. Rub the bottom of the sink vigorously with the stiff side of a sponge until the lime, dirt, and stains have been removed, then rinse thoroughly with water.
Granite is a very dense material made deep in the earth’s core, while marble is formed from calciferous sediments associated with the sea floor. Both materials turn into stone over eons, but the minerals in these two stones make them react differently to conditions in the home and outdoors.
In granite composite, natural stone and resin are heated and molded into a solid surface, ultimately making it much harder, more durable, and less expensive than marble.
Both renowned for their incredible durability and low maintenance, these two materials come with some key differences. The most obvious is their appearance, with granite composite sinks available in a variety of finishes, while stainless steel is essentially only available in one color.
While granite composite is much lower in cost than natural stone, it is still on average more expensive than stainless steel options. Also, due to the heaviness of a composite granite sink, it typically requires additional support while stainless steel is lightweight and, thus, easier to install.
Granite composite is heat resistant, making it unaffected from exposure to ordinary sources of heat in a household. Due to the acrylic resin present in this material, however, it is not heat proof. You won’t want to place scolding hot pots or pans in your composite granite kitchen sink.
To prevent possible damage, avoid extreme changes in temperature as well, such as placing something cold in the sink right after placing something hot on that area.
Since the material is not entirely heat proof, you’ll want to avoid pouring boiling water in a granite composite sink.
Thanks to the hardness of granite composite sinks, it is uncommon for them to chip or crack when other types of sinks generally would. Proper care and maintenance are key in avoiding damage.
If your granite composite sink does crack, it can be fixed with composite sink repair epoxy. Be sure to follow the specific product’s instructions carefully.
Granite composite sinks are one of the easiest sinks to keep clean. Rinse away any standing liquids with every use, and for daily cleaning, use a gentle liquid soap and non-abrasive materials. If followed accordingly, this is the extent of its maintenance.
Since the material is non-porous, it is not necessary to seal a granite composite sink, with general upkeep being the best way to keep your sink looking new.
If standing liquids are not rinsed away quickly and are left to sit for too long, this could cause your granite composite sink to stain, with light-colored options more visible. Be especially mindful of coffee, tea, fruit juice, or anything highly acidic left in your sink.
