Unlike natural stone or wood, it never needs to be sealed. Just wipe with soapy water for daily upkeep. Surface stains can be removed with a gentle cleansing scrub. Avoid scouring pads, which can dull the surface, and harsh chemicals that could break down the bonds between the quartz and resins.
Resin binders make quartz counters nonporous, so stain- and odor-causing bacteria, mold, and mildew can’t penetrate the surface.
Some makers offer jumbo slabs for uninterrupted runs of countertop. But even with standard slabs, typically 60 by 120 inches, the seams can be almost imperceptible; added resins allow cleaner cuts without chipping as stone does. The resins also make quartz more flexible than natural stone, allowing fabricators to bend and shape it into sinks or the sides of a curved island. And it’s versatile enough to be used on floors and walls—fabricators can even cut the slabs into standard tile sizes.
Compared with DIY options, such as wood, laminate, and concrete, which can cost less than $10 per square foot, quartz, like granite, is expensive—about $60 to $90 per square foot, including installation. Acrylic solid surfacing, another competing option, costs about $40 to $80 per square foot installed.
It can’t take extreme heat.
Quartz counters are heat and scorch resistant, but only up to a point. Most manufacturers say their products can handle up to 400 degrees F, but a sudden change in temperature or sustained heat from a pan left on the counter may cause the surface to crack. To be safe, always use a trivet or a hot pad.
It can’t weather outdoor use.
Install it outdoors in an uncovered area, and you’ll void the warranty. Direct sun beating down on it day after day can cause colors to fade or the countertop to warp or split over time. Currently, none of the major manufacturers offers an outdoor-approved quartz counter.
