Should White Quartz Countertops Be Sealed?

Many consumers choose variations of white quartz because of it's predictable patterning, beautiful colors and durability. 

Today we received an email from a customer that recently had a white quartz countertop installed in her kitchen. Having questions about quartz care and maintenance, she reached out to us with an email. 

    From The Customer: "Leigh P"

    We just installed new white quartz countertops. The company we used said that it is man-made and therefore doesn't need to be sealed. I just read somewhere on the internet that you should never "seal" quartz countertops. Can / should I use your Granite, Quartz & Marble Treatment to make them more shiny and bright? They said it could dull the shine over time.

    From Our Stone Pro: 

    It is true that engineered stone countertops, or “quartz countertops,” are man-made. However, this has nothing to do with the rate of absorption. It is also true that you shouldn’t use a “penetrating sealer” on quartz counters. Quartz counters are made with a natural stone aggregate and resin. The unsaturated polyester resin can have an adverse reaction with a solvent based sealer. This is why it is not recommended to seal quartz countertops, not because it will not stain.  

    As you have discovered, quartz counters do not shine like a polished granite. It is not recommended to use a polish on quartz surfaces because a polish that contains wax will build up and show wear. However, there are alternative solutions to polishes that contain wax. For example, ioSeal™ won't build up like a typical wax. It adds shine and progressively seals, adding an additional level protection. Supreme Surface® Granite, Quartz and Marble Treatment with ioSeal offers a safe and simple solution to clean, shine and protect all engineered stones, including quartz countertops.

      A contractor chipped one of the two quartz quarter-round shelves in the tub enclosure he installed. I asked him to replace it. Instead he ground off the edges of both shelves so they are no longer shiny. I don’t mind the look. I am concerned they may stain or be damaged with use. Can you answer this query?
