Continue reading to learn more about this stylish stone countertop material, how it's made, and how it works.


What is Granite?


Granite is a natural stone that is formed from liquid magma under pressure for many years. This stone differs in color, texture, and crystalline structure. There are three main minerals common in granite, feldspar, quartz, and mica. These minerals can be present in the stone in different proportions, which give the different appearances and color of the stone.


Cutting the Granite


Most of the time, granite is cut at the quarry. However, it's not uncommon for the installer to cut the granite on-site before the installation. The key to cutting the slab is accurate measurements of the installation area.


The installer will use a saw that's fitted with a diamond cutting blade to cut this hard stone. Cutting granite dry will produce significant amounts of dust, so most professionals will perform the cutting with a vacuum fitted onto the saw or a wet saw.


Once the basic shape of the countertop has been cut out, it will need to be edged. Typical edges for granite countertops are flat, beveled, rounded, and curved. The edging is typically performed with an edge-shaping machine that cuts and polishes as it goes.


Granite Countertop Installation


The first step of installing granite countertops is moving the appliances away from the existing countertop and removing the countertop, if applicable. Next, is the stage where the accurate measurements previously mentioned come in handy.


The new countertop will need to fit appliance openings, be flush with cabinet ends, and match up with the sink's placement. The granite is generally installed with plastic sheeting or a vulcanized rubber barrier between the sub counter and the granite countertop.


The vast majority of granite counters will have at least one seam as the slabs are usually less than 10 feet long. Silicone will be applied in the seam to account for expansion and contraction. A specialized epoxy secures the granite in place, then a colored glue is used to hide any visible seams.


Sealing the Granite Countertop


Granite is a natural, porous stone that can absorb water and other liquids. It needs to be sealed to protect the granite from damage and staining from liquids. Sealants prevent liquids from absorbing into the granite and will cause them to bead on the surface instead.


The countertop needs to be sealed after its installation and usually needs sealing annually afterward. A simple way to check if your granite is ready to be resealed is by dripping water onto it. If it soaks in, it's time to reseal. Most sealers will dry in several hours or will need to dry overnight.
