What’s Quartz Countertop? The Ultimate Guide

Quartz countertops have become an increasingly popular option for home kitchens and bathrooms in recent years. But what exactly is a quartz countertop? In this comprehensive guide, we’ll explore everything you need to know about quartz countertops, including what they are, their benefits and drawbacks compared to other materials, how they are made, how to choose the right one, and proper care and maintenance.

What is Quartz?

Quartz is a man-made material engineered from natural quartz crystals combined with resins and pigments. Natural quartz is an abundant mineral found all over the world. It is extremely hard and durable. When pulverized into a fine powder and combined with chemicals and resins under heat and pressure, this material forms an engineered stone product with the look and feel of natural stone.

What Sets Quartz Apart From Other Countertop Materials?

Quartz vs. Granite

Granite is mined from quarries as large natural stone slabs. It has a classic, elegant look but requires periodic sealing to prevent stains. Granite is more porous than quartz. Quartz has a similar aesthetic to granite but has superior durability and doesn’t need regular sealing.

Quartz vs. Marble

Marble is a softer metamorphic stone often used for sculptures and countertops. It stains and etches easily, requiring frequent repolishing. It has a high-end, luxurious appeal but requires more maintenance than quartz. Quartz offers more consistent patterning and better scratch resistance than natural marble.

Quartz vs. Laminate

Laminate countertops are made by gluing plastic resin onto a plywood or composite wood base. A photographic applique layer creates a faux look. Laminate is affordable but can bubble, burn, scratch, and stain easily. Quartz is non-porous, making it more stain, scratch, and heat-resistant than laminate.

Quartz vs. Solid Surface

Solid surface countertops are made of acrylic or polyester resins and binders. Popular brands include Corian and Avonite. Solid surface is prone to cuts, scratches and heat damage without proper care. It can be repaired seamlessly but requires more maintenance than quartz.

Quartz vs. Tile

Tile countertops offer design flexibility using various materials like ceramic, porcelain or stone tiles. Grout lines can trap bacteria though, requiring thorough cleaning. Quartz has seamless installation and doesn’t need grout lines that can crack and stain over time.

Quartz vs. Butcher Block

Butcher block wooden countertops provide a timeless, rustic look that fits many kitchen styles. However, they can warp from moisture and require diligent oiling to prevent cracking, mold, and bacteria. Quartz resists stains, doesn’t harbor bacteria, and maintains its shape over time.

Quartz vs. Soapstone

Soapstone is a naturally gentle, soft stone often carved into vessels and countertops. It is heat tolerant but scratches and stains easily. Special oils provide waterproofing. Low-maintenance quartz provides better durability than porous soapstone.

How are Quartz Countertops Made?

Quartz countertops are made by blending roughly 90% ground natural quartz with about 10% polyester resins, pigments, and other compounds. This mixture forms a moldable material that is pressed into slabs under tremendous heat and pressure.

The manufacturing process involves:

  • Crushing quartz crystals mined from the earth into a fine powder
  • Mixing the crushed quartz with resin binders, pigments and filler
  • Pouring this blend into molds and compacting at high pressures
  • Baking at high temperatures to cure and harden the slabs
  • polishing and finishing the slabs to achieve the desired surfaces
  • Cutting the slabs into various sizes using diamond-tipped saws
  • Fabricating countertops according to exact specifications for installation

Reputable quartz manufacturers carefully control the engineering process to produce slabs with optimal durability, beauty, and consistency. Their formulations and techniques vary to achieve unique styles. Different particle sizes, patterns, pigments, and finishes create the amazing array of quartz products on the market.

How to Shop for Quartz Countertops

Research Brands and Colors

The first step is exploring the major quartz manufacturing brands like Caesarstone, Cambria, Silestone, Vicostone, Hanstone, Quartzforms, and Viatera. Compare their color palettes and overall aesthetics. Narrow your selection to a few favorite brands and slab styles.

Consider visiting quartz suppliers’ showrooms to view samples in person. Examine the textures and colors closely. Look at how each brand’s products coordinate with your cabinetry, flooring, appliances and decor.

FAQs about Quartz Countertops

Is quartz healthier than granite?

Quartz does not absorb liquids so it resists mold, mildew, and bacteria growth better than porous natural stones. However, both offer inert, non-toxic surfaces suitable for food preparation when properly cleaned.

How long do quartz countertops last compared to other options?

With proper care, expect around 15-25 years of beauty and performance from quartz surfaces. Well-maintained granite may last 50+ years. Porous marble and soapstone require more maintenance. Laminate lasts 5-10 years before needing replacement while quality wood can last 25+ years.

Can you cut on quartz countertops?

It’s best to avoid direct cutting on quartz. Use a cutting board to protect finishes. The occasional slicing won’t damage quartz but repeated cuts in the same spot may eventually leave light marks over time.

Do quartz countertops stain?

Quartz resists staining much better than porous stones. However, highly pigmented spills allowed to sit for prolonged periods can result in stubborn stains that may require professional removal. Prompt clean-up of spills minimizes chances for discoloration.

Is quartz toxic?

Quartz engineered stone is considered non-toxic when manufactured by reputable companies. However, some lower quality products contain harmful levels of crystalline silica. If concerned, contact the manufacturer for safety data sheets before purchasing quartz.

Is quartz cheaper than granite?

Quartz countertops often cost $5-15 less per square foot compared to granite. However, more exotic granite types can be comparably priced to premium quartz. Local material and labor costs factor in too. Get quotes on your exact project to compare.

Can quartz countertops crack?
