How to Damage Quartz Countertops

Quartz countertops are engineered stone surfaces made from roughly 90% ground natural quartz crystals combined with polymer resins and pigments. They are an incredibly popular countertop choice due to their durability, aesthetic appeal, and ease of maintenance. However, quartz is not indestructible and can become damaged under certain circumstances. This article will provide tips on how to intentionally damage quartz countertops for individuals wanting to remodel or conduct destructive testing.

Use Extreme Heat

Applying a very high level of concentrated heat on a quartz countertop can cause damage. Here are some ways to use extreme heat to damage quartz:

  • Place a cast iron pan, griddle or pot that has been pre-heated to over 500°F directly onto the quartz surface. The intense heat will scorch and potentially crack the resin binders.
  • Utilize a torch for purposes like crème brûlée and let the flame linger too long in one spot. The flaming heat can singe, blister and degrade the quartz.
  • Expose sections of the countertop to prolonged contact with very hot pots and pans fresh from the stovetop or oven. The residual heat will take a toll over time.
  • Enable a stovetop burner to remain on high for an extended period with no cookware on it. Direct the resulting concentrated flame against the quartz to blister and burn through top layers.
  • Use a heat gun, circular saw capable of 2500°F or other extreme heat-generating power tool on the countertop without proper cooling. The spot-exposure can char and gouge the quartz.

Quartz is designed to withstand typical household cooking temperatures. But excessive direct heat over 500°F applied consistently in one area can start to compromise the solidness of the material. Scorch marks, cracks, discoloration and deterioration can occur.

Subject to Prolonged Cold Temperatures

While quartz itself can withstand very cold temperatures as an engineered stone, the resin binders are vulnerable to sustained freezing conditions. Here are ways to potentially use cold to damage quartz:

  • Placing ice packs or dry ice directly on the countertop for hours at a time can make the resin brittle and more prone to cracking and chipping.
  • If the quartz countertop is installed in a vacation property or secondary home, subjecting it to weeks of sub-freezing indoor temperatures with no climate control can start to erode the structural integrity from contraction and expansion of the binding agents.
  • Remove a section of quartz from the rest of the countertop and place it in a freezer for an extensive period. The isolated cold on just one section can exacerbate issues from contraction and expansion as the temperature shifts.
  • Utilizing a can of compressed air turned upside down blows out very cold liquid and vapor. Hold the can close to the countertop surface and blast away to freeze a localized section of the quartz.

While quartz itself is non-porous and not prone to cracking from minor cold exposure, keeping the countertops consistently under frigid conditions can potentially start to break down the structural stability over a long duration.

Hit with Extreme Blunt Force

As an engineered stone, quartz has impressive impact resistance compared to natural stone. However, a high level of blunt force and pressure applied repeatedly can start to smash and fracture quartz. Here are ways to damage quartz using brute blunt force:

  • Taking a sledgehammer or pickaxe to different areas can fracture quartz, especially on seams, corners and edges. This extreme measure obviously comes with safety concerns.
  • Dropping extremely heavy objects such as dumbbells, iron kettles or a butcher block from countertop height onto the quartz can potentially crack the surface on impact.
  • Using a jackhammer on a small section of quartz essentially pounds the spot with concentrated bursts of power. This can crush and split the crystalline structure.
  • Whacking the countertop aggressively with a baseball bat, crowbar, golf club or similar blunt object may start to cause chips and cracks at the point of impact with repeated strikes.
  • Placing the quartz slab on the floor and jumping on it repeatedly from a height can potentially damage it with your concentrated body weight and force.

Quartz has impressive break-resistance capabilities compared to other countertop materials. But extreme trauma from deliberate harm using heavy blunt objects may inflict surface or structural damages.

Cut, Slice and Puncture

Quartz contains roughly 90% ground quartz crystals bound together by polymer resins. This makes it vulnerable to being cut, sliced and punctured to purposefully inflict damage:

  • Using a circular saw with a diamond or carbide blade allows you to cut right through a section of the countertop. Make cross-cuts at different points.
  • Take a sledgehammer and chisel set and carve into the quartz surface in different areas by hammering the chisel tip into the stone.
  • Utilize an angle grinder or rotary tool with a tile-cutting blade to slice into corners and edges of the countertop.
  • Abrasive hole saw drill bits can bore into the quartz to create damage by drilling overlapping holes.
  • Hammering a masonry nail through a section of the countertop punctures the surface and cracks the quartz. Use a chisel and hammer to expand the puncture damage.
  • Running a sharp knife repeatedly in the same scoring pattern slices into the surface resin binders and quartz crystals.

Any tools capable of cutting through natural stone can slice, carve, drill, puncture and penetrate quartz surfaces to inflict scratches, chips, scores and holes. The polymer resins will crumble around affected areas.

Use Corrosive Chemicals

Quartz has excellent resistance to acids and bases found in everyday kitchen settings. However, prolonged exposure to certain harsh chemicals can degrade and discolor the appearance of quartz:

  • Drain cleaner containing sulfuric acid or muriatic acid brushed onto the surface and left to sit can etch and corrode quartz.
  • Oven cleaners designed for heavy grease removal often contain sodium hydroxide (lye). If left to linger on the countertop, it can stain and pit the quartz.
  • Spray paint chemicals, brush cleaners, oil soaps and other detergents with corrosive ingredients can break down the polymer resins if left for hours.
  • Industrial cleaning agents like bleach, alkaline based strippers and concentrated hydrogen peroxide may lighten, spot or rough up the quartz if allowed to repeatedly soak into the surface.
  • Solvents like acetone, paint thinner and nail polish remover can stain and dissolve the resin binders if spilled and not cleaned promptly.

While quartz has excellent tolerance for typical household acids, prolonged chemical exposure especially if not wiped quickly can damage the appearance and integrity of the material over time.

Thermal Shock

Rapid and extreme temperature changes can create thermal shock in quartz surfaces and cause structural issues:

  • Going from very hot to cold such as pouring an ice bath onto a quartz countertop fresh from the oven can make it crack or warp.
  • Placing a hot stovetop pan onto a quartz bar area cooled by an overhead air conditioning vent creates a major shift that induces thermal shock.
  • Allowing the quartz surface to get steaming hot then spraying it with cold water causes the stone to expand and contract too quickly.
  • Storing the quartz pieces outdoors in summer heat then bringing them into an air conditioned home for installation makes them highly susceptible to shock.
  • Heat lamps directed at a section of the countertop then removed and replaced by frozen ice packs causes abrupt temperature extremes the quartz cannot adjust to gradually.

The key is creating quick changes between temperature extremes that the stone cannot adapt to incrementally. This destabilizes the crystalline structure at a molecular level which can make the quartz prone to damage.

Improper Installation

Quartz requires being fabricated and installed properly to create structural durability. Here are ways improper installation can make it vulnerable to damage:

  • Not allowing adequate expansion space between the countertop and walls makes it prone to cracking from natural motion.
  • Forgetting to adhere the countertop to the cabinet base with adhesive causes instability and increased risk of impact damage.
  • Failing to anchor heavy quartz pieces like islands and bars with brackets underneath prevents essential support.
  • Not matching the edge profile from the factory precisely where sections meet prevents a tight seam and causes gaps where moisture and debris can enter.
  • Joining countertop pieces incorrectly keeps them from becoming level, allowing one side to bear the brunt of chopping and cutting forces.
  • Mishandling quartz pieces during transport and installation (dropping, banging, excessive vibrations) can fracture segments prior to final placement.

Quartz must be installed as precisely as possible to factory specifications to maximize durability. Taking shortcuts exposes it to greater likelihood of damage over time.

Neglect Routine Maintenance

Quartz requires minimal but consistent maintenance to retain its integrity. Neglecting certain care issues can open the door for potential damage:

  • Allowing spills like wine, oil and soap residue to linger without cleaning degrades the surface over time.
  • Failing to utilize cutting boards and hot pads regularly in kitchen traffic zones causes premature wear and tear.
  • Not re-sealing the countertop every 1-2 years enables moisture penetration into worn areas around sinks.
  • Forgetting to clean under mount sinks keeps water pooling against the quartz, jeopardizing water-resistant properties.
  • Allowing soap and hard water stains to accumulate degrades visible clarity and polish over time.
  • Letting cracks and impact chips go unrepaired exposes more severe structural issues long-term.

While quartz is low maintenance compared to other surfaces, ongoing care is vital. Neglect accelerates visible wear-and-tear and opens the door to more significant damage vulnerabilities.

Mishandle the Material Itself

How quartz countertops are treated during the fabrication, transportation and installation process can make them prone to damage:

  • Failure to keep slabs supported evenly when carrying and moving makes them prone to cracks and breaks.
  • Banging corners and edges against walls and doors causes chips and fractures.
  • Having pieces stacked or leaned unevenly during storage enables cracking.
  • Exposing unfinished sides to moisture causes expansion issues that disrupts smooth installation.
  • Letting pieces sit in extreme temperatures during transport shrinks or expands segments that don’t fit right.
  • Vibrating unfinished pieces unsecured during transport can fracture segments.
  • Moving or installing slab pieces with rough, hurried motions rather than gentle finesse and care.

Quartz requires proper handling from the fabrication plant to installation to maintain its renowned damage-resistance. Rushing the process or bouncing segments around haphazardly puts the material at risk.

Use Quartz Outside of Recommended Applications

Using quartz beyond its intended function makes it prone to damage:

  • Utilizing outdoor quartz pieces indoors where sunlight intensity magnifies heat absorption and expansion vulnerabilities.
  • Installing a recently fabricated thick quartz piece onto a floor adds weight and foot traffic stresses the surface was never designed to endure.
  • Cutting pieces from the interior of a slab for use as floor tiles lacks the impact-resistance of outer edges.
  • Expecting laboratory-grade quartz to have the same performance capacity as quartz engineered for commercial spaces.
  • Assuming household quartz can withstand the same thermal, chemical and structural rigors as industrial-application quartz.

Quartz engineered stone has specific design applications matching its fabrication strength and composition. Using it outside those parameters exposes weaknesses that enable damage.
