Quartz countertops are engineered stone surfaces made from quartz particles combined with resins and pigments. With their durability, visual appeal, and easy maintenance, quartz countertops have become immensely popular in recent years for home kitchens and bathrooms. However, many homeowners wonder whether quartz can be cut to size like natural stone. Here is what you need to know about cutting quartz countertops.

An Introduction to Quartz Countertops

Quartz countertops, also known as engineered stone or engineered quartz, are made of approximately 90% ground natural quartz blended with polyester resins and pigments. The resins bind the quartz particles together to form a durable, non-porous surface. Quartz is one of the hardest minerals, so quartz countertops are extremely scratch, stain, and heat resistant.

Unlike natural stone, quartz slabs are fabricated in factories under precise conditions. This allows manufacturers to control the color patterns and veining in the material. As a result, quartz counters come in a vast array of styles and colors from solid tones to varied patterns that mimic marble or granite. However, quartz lacks the natural imperfections of stone since it is engineered.

Quartz counters are routinely installed as countertops in kitchens and bathrooms. The minimal maintenance requirements make quartz an ideal surface for busy kitchens prone to spills and stains. Quartz resists moisture, lending itself well for bathroom vanity tops. With proper sealing, quartz can also be installed outdoors in areas like patios.

Can You Cut Quartz Countertops?

Yes, quartz countertops can be cut to size during installation. However, cutting quartz requires specialized tools and techniques to achieve clean edges and prevent cracking or chipping.

Quartz slabs are prefabricated in set dimensions, usually about 118 inches long by 55 inches wide. Since few countertops are exactly that size, nearly all quartz counters need some cutting to custom fit the layout of the kitchen or bathroom.

Cutting is typically done by professional installers rather than homeowners. This ensures the best possible results when working with an engineered stone.

Equipment for Cutting Quartz Countertops

Cutting quartz countertops requires diamond-bladed power tools made specifically for stone fabrication. The most common tools are:

Wet diamond saw: A table saw with a continuous diamond blade that cuts quartz slabs immersed under water. The water prevents overheating and cools the blade.
Angle grinder: A handheld rotary tool with diamond blades that cut and polish quartz edges. Special vacuum attachments minimize dust when grinding.
Jigsaw: For making circular or curved cuts in quartz, a jigsaw with a diamond-grit blade is essential. Water is used to keep the cutting line cool.

Standard woodworking saws are ineffective and unsafe to use on engineered stone. The brittle nature of quartz will rapidly damage carbide and steel blades. Friction and heat buildup can also crack and shatter the slab.

In addition to cutting tools, installers use backer boards, clamps, adhesives, and fasteners designed for quartz fabrication.

How to Cut Quartz Countertops

Cutting quartz to create counters that fit a particular kitchen layout involves several steps best left to professionals:

Measuring and Marking

The first step is carefully measuring the dimensions of the counter space. The quartz slab is marked where cuts need to be made. Marks account for overhangs and any seams between two slabs.

Straight Cuts

Straight cuts along the length or width of the slab are made using a wet diamond saw. The installer positions the slab on the saw table and aligns the marked cutting line with the blade. Steady feed rate and ample water prevents cracking.

Irregular Cuts

For cutouts like sink holes or L-shaped edges, holes are drilled at the inside corners. The jigsaw then cuts along the marked outline to create the desired shape. Again, water keeps the blade cool during the process.

Cutouts and Holes

Any necessary openings for appliances, plumbing, outlets, etc. are cut using a combination of jigsaws, diamond hole saws, and angle grinders. Cuts may need to be smoothed and polished after.

Edge Finishing

Once cut to size, the sides and edges of the quartz slab must be profiled and polished. Grinders equip with smoothing pads and diamond polishing pads are used to create clean, even edges.

Cutting Tips to Avoid Damaging Quartz

Cutting quartz incorrectly can result in cracked, chipped, or uneven edges. Follow these tips to get perfect cuts:

Take time marking measurements twice to cut once
Work slowly and steadily with the saw blade fully submerged
Apply even pressure when feeding the slab through the saw
Use light pressure when grinding edges
Keep the slab stable and supported on a rigid work surface
Allow the quartz to cool completely between cuts
Change diamond blades before they become too dull

With care and the proper tools, quartz can be cut and shaped into beautiful custom countertops. Hire experienced professionals for best results, or have a fabricator cut the slabs for a DIY installation.

FAQs About Cutting Quartz Countertops

Can I cut quartz countertops myself?

It is not recommended for DIYers to cut their own quartz. The specialty diamond-bladed tools are expensive and difficult for amateurs to control well. Mistakes made during cutting cannot be undone, so it is best to have an experienced fabricator or installer handle any needed cuts.

Does quartz need to be sealed after cutting?

Unlike natural stone, quartz does not require sealing. The resins make quartz non-porous, so it will not absorb moisture that can lead to staining and damage. However, sealing the edges after cutting ensures that any exposed spots remain water-resistant.

Do you need to polish quartz after cutting?

Polishing the cut edges is important to restore the smooth factory finish. Diamond polishing pads mounted on an angle grinder smoothly buff the sides of the quartz. Some small chipping may occur during cutting that also needs polishing out so the edges look neat.

Can you cut quartz with a circular saw?

No, a standard circular saw cannot effectively or safely cut quartz. The composite material is too hard for steel or carbide blades. Friction and heat buildup will damage both the quartz and saw. A wet diamond blade saw is required to cut quartz countertops without cracking them.

How thick should quartz countertops be?

Quartz countertops are typically available in thicknesses between 2 cm (0.8 inches) and 3 cm (1.2 inches). Thicker slabs are recommended for counters in heavy use, such as kitchens. Bathrooms can utilize thinner 2 cm quartz. Weight is also a consideration, with thicker quartz being much heavier.

Conclusion

With the right tools and techniques, quartz countertops can be cut and fabricated to install beautifully in any space. While quartz is not as forgiving as wood if mistakes are made, experienced installers know how to cut quartz properly to create lasting counters.

Following safety precautions like water-cooled diamond blades prevents the brittle material from cracking. Finishing the cut edges with grinding and polishing ensures that the engineered stone retains its elegant look. With customized sizing and virtually maintenance-free durability, it is easy to see why cut-to-fit quartz has become a go-to countertop material.
