While granite needs to be sealed once it's installed and requires resealing at least once a year, Caesarstone doesn't require sealing because it's made of quartz. The non-porous and dense quality of quartz takes away the need for sealant.
Lighter granite variations are more likely to develop stains compared to darker variations due to its porous nature. Caesarstone is highly resistant to stains caused by most liquids. Granite is a natural stone that comes in multiple varieties. It differs according to its source, colors, chemical composition, porosity and density among other factors. Meanwhile, Caesarstone is a mass-produced product that uses 93 percent quartz aggregates and 7 percent pigments and resin.
