How to Install Quartz Tile Countertops

Quartz tile countertops can be a beautiful and durable addition to any kitchen or bathroom. Installing quartz tile is a bigger project than installing regular ceramic tile, but with proper planning and patience, a DIY homeowner can achieve professional-looking results. This comprehensive guide will walk you through everything you need to know to successfully install quartz tile countertops in your home.

Introduction to Quartz Tile Countertops

Quartz tile has become an increasingly popular choice for countertops due to its many benefits:

  • Durability: Quartz tiles are made from 90% ground natural quartz making them harder and more scratch-resistant than granite. Properly sealed, they can withstand years of daily use without showing signs of wear.
  • Low Maintenance: Quartz tiles do not need to be regularly sealed like natural stone and are non-porous, so they do not need frequent polishing and are resistant to stains. Simple cleaning with soap and water is all that is required.
  • Resistance to Heat and Scratches: Quartz tiles are more heat, scratch, and chip resistant than granite or marble countertops. However, it is still important to use trivets and cutting boards to protect the surface.
  • Wide Variety of Colors and Patterns: Quartz tiles come in a vast array of colors, styles, and patterns allowing for lots of design flexibility. Tiles can be matched or mixed-and-matched to create custom looks.
  • Seamless Look: The small size of the tiles means grout lines can be tightly spaced to create a seamless look. Grout color can also be matched to the tiles.

With proper installation, quartz tile countertops can be a wise investment that adds beauty and luxury to a home. They provide an upscale yet practical surface perfect for kitchens and bathrooms. Read on to learn everything involved in a DIY quartz tile installation.

Planning Your Quartz Tile Countertop Project

Careful planning and preparation are key to achieving success with a DIY quartz tile countertop installation. Rushing into the project can lead to mistakes, so take the time upfront to consider all the important factors:

Selecting Your Tile and Color

There are many aesthetic factors to think about when selecting quartz tiles:

  • Color/Pattern: Choose something that matches your overall design plan. Go for lighter colors if aiming for an airy look or dramatic darker tiles for a bold style.
  • Tile Size: Standard sizes are 12 x 12 inches, 12 x 24 inches or 16 x 16 inches. Tile thickness is usually 0.5 inches.
  • Tile Edges: Options include square, rounded or beveled edges. Rounded or beveled edges give the countertop profile more depth.
  • Grout Color: Often grout is matched to the tile color, but contrasting grout can be eye-catching. Dark grout needs extra sealing/cleaning.
  • Textures/Finishes: Quartz tiles come in polished, matte or textured finishes. Textures like concrete, stone or slate can add extra visual appeal.

Be sure to order extra tiles to account for cuts, waste and future repairs. It is recommended to add at least 15% more tiles to your total countertop square footage.

Choose the Right Adhesives and Tools

Installing quartz tile requires using the proper adhesives, tools, and materials:

  • Adhesive: Use a premium grade white polymer modified thinset mortar that is flexible and designed for natural stone installation.
  • Grout: Choose an unsanded polymeric grout designed for grout joints 1/8 inch or smaller. Match grout color to tiles.
  • Sealant: Use a penetrating non-toxic sealant formulated for natural stone that does not alter surface appearance. Test sealant first.
  • Wet Saw: Essential for making precise cuts in quartz tiles. Use a diamond tile blade.
  • Rubber Grout Float: Needed to force grout into tight spaces between tiles. Handle must be flexible.
  • Grout Sealer: Seals grout pores and prevents staining or discoloration.
  • Cheesecloth: Used to buff off excess grout sealer before it dries.

Having the right tools like tile spacers, a rubber mallet and mixing buckets will also make the installation process easier.

Measure Carefully for an Accurate Template

  • Carefully measure the dimensions of the countertop including any seams where two pieces meet. For kitchen islands, measure each side.
  • Make a template from heavy paper or cardboard cut to the exact size needed. This will be your reference when cutting the tiles.
  • Plan the tile layout ensuring tiles at the edges are no less than a third of a full tile. Draw the pattern on the template.
  • Make sure outlets, faucets and appliances will align with the tile layout. Adjust template if needed.
  • Use the template to determine the total number of tiles needed in your chosen colors/patterns. Adjust the template as needed to minimize cuts.

Accurate measurements and tile planning will help prevent expensive mistakes and reduce tile cuts.

Preparing and Installing Your New Tiles

Once planning and prep work is complete, it is time to start installing your beautiful new quartz tile countertop. Follow these key steps for proper installation:

Ensure a Smooth, Clean Surface

The tiles will only be as strong as the underlying surface, so proper preparation is crucial:

  • If installing over an existing countertop, thoroughly clean and lightly sand the surface to improve adhesion.
  • For new build outs, make sure the surface is smooth, plumb, and free of defects before adding tile.
  • Clean the surface thoroughly to remove any grease, dirt or grime which could prevent proper bonding.

Taking time to properly prepare and level the surface will prevent future problems with cracking or loosening tiles.

Cut Tiles to Fit Your Template

Carefully cut the quartz tiles to match the template design:

  • Use a wet saw with a diamond blade to make precise straight cuts without damaging tiles.
  • Cut tiles exactly as marked on the template, taking care with measurements.
  • Make small precise cuts for any outlet covers or plumbing fixtures.
  • Set cut tiles onto the template to ensure proper fit before installing.

Measure twice and cut once to avoid wasting tiles! Having extra tiles on hand is helpful in case any mistakes are made.

Apply the Adhesive and Set Tiles

Follow these steps when setting tiles:

  • Apply a thin layer of premium adhesive using a notched trowel over an area that can be comfortably tiled within 10-15 minutes.
  • Use a rubber grout float to press tiles firmly into the adhesive and set them precisely according to the template.
  • To achieve a flat surface, use tile spacers between rows leaving a consistent 1/8 inch gap for grout.
  • Before adhesive dries, check tiles to ensure they are level with no uneven spots and adjust as needed.
  • Allow adhesive to dry completely per manufacturer instructions before moving on (usually 24-48 hours).

Working methodically and carefully checking alignment will help create a perfectly flush countertop surface once grouted.

Applying and Sealing the Grout

Adding and sealing the grout completes your quartz tile installation:

  • Use a rubber grout float or squeegee to force grout into the 1/8 inch gaps between tiles. Spread excess grout over the surface to ensure all gaps are completely filled.
  • Wipe excess grout off the surface using a clean sponge and water. Buff surface with a soft cloth to remove any remaining grout residue.
  • After grout has dried per package directions, apply grout sealer evenly over the entire surface to seal and protect the grout. Polish off any excess once dry.
  • Avoid using the countertop for at least 72 hours to allow grout and sealers to fully cure before regular use.

Properly sealed grout prevents stains and damage to your countertop over time. Always test sealers in an inconspicuous area first to ensure it does not discolor the tiles.

Caring for and Maintaining Quartz Tile Countertops

Follow these recommendations to keep your quartz tiles looking like new for years:

  • For daily cleaning, use only gentle soap and water applied with a soft sponge or microfiber cloth. Avoid harsh cleansers which can damage the finish.
  • Immediately wipe up any spills to prevent possible staining, especially oils, wines, or acidic substances like citrus juice.
  • Reapply grout sealer every 1-2 years per manufacturer recommendations to protect from staining or moisture damage.
  • Avoid exposing the tiles to excessive heat by always using trivets, hot pads or cutting boards. Prolonged high heat can cause cracking.
  • Check tiles and grout lines periodically for any cracks or damage. Repair issues immediately to prevent moisture intrusion.
  • Use coasters under glasses and wipe the area dry after use to prevent etching of the surface over time.

Following these care tips will help maintain the beauty and integrity of your quartz tile countertop. Be sure to enjoy showing off your stylish new surface!

Frequently Asked Questions About Installing Quartz Tile Countertops

What kind of saw blade is best for cutting quartz tile?

For clean, precise cuts without damaging the tiles, it is recommended to use a wet saw with a good quality diamond blade specifically designed for cutting porcelain, ceramic or natural stone tiles.

Can quartz tiles be installed directly over existing countertops?

In most cases, quartz tiles can be installed over existing countertops like laminate, granite, or solid surface countertops provided the surface is properly prepped. The surface must be thoroughly cleaned, dried, and sanded to ensure proper adhesion.

Should sanded or unsanded grout be used with quartz tiles?

For grout joints 1/8 inch or less, it is recommended to use unsanded polymeric grout designed for tiles with tight gaps. Avoid heavily sanded grout which can scratch the tile surface. Match the grout color to the tiles.

How soon can I put items on the countertop after installing quartz tile?

It is best to avoid placing anything on the new quartz tile surface for at least 72 hours. This allows the adhesive, grout, and sealers to fully cure first. After 3 days, the countertop should be ready for regular use.

Do quartz tiles need ongoing sealing like granite?

Unlike natural stone, quartz tiles do not require periodic sealing throughout their lifetime. Only the grout lines need to be sealed every 1-2 years to prevent staining or moisture penetration. The tiles themselves are non-porous and stain resistant.


Installing a quartz tile countertop can provide a kitchen or bath with a high-end luxury look while being a durable and low maintenance surface. With the right planning, patience, and attention to detail, DIYers can achieve professional results. The number of colors, patterns and textures available means you can create a countertop that perfectly suits your personal style.
