How to Stick Quartz Countertop

Installing quartz countertops can transform the look of your kitchen or bathroom. With their sleek appearance and durability, quartz countertops are a popular choice for home renovations. However, proper installation is crucial to ensure your countertops last for years to come. Learning how to stick quartz countertops correctly will help get your project off to the right start.

Choosing an Adhesive

When installing quartz countertops, using the right adhesive is critical. Here are some tips on selecting the best adhesive:

  • Opt for a high-quality 100% silicone or polyurethane adhesive. Avoid cheap, water-based adhesives.
  • Choose an adhesive designed specifically for quartz and solid surface countertops. These adhesives are formulated to bond quartz.
  • Make sure the adhesive can withstand heat up to 212°F to accommodate hot pans.
  • Consider an adhesive with built-in spacers to simplify installation.
  • Clear adhesives work well as they allow you to monitor full adhesive coverage.
  • Follow the manufacturer’s instructions for best practices with the particular adhesive.

Using the manufacturer-recommended adhesive for your specific quartz material will provide the strongest, most seamless bond when learning how to stick quartz countertops.

Preparing the Surface

Proper preparation of the surface where your quartz countertop will be installed is imperative for a long-lasting connection. Here is how to prepare the surface:

  • The surface must be completely clean, dry, and free of debris. Remove any old adhesive, grease, wax or soap film.
  • Sand the surface lightly to improve adhesion. Take care not to damage the underlying surface.
  • For natural stone or concrete, use a primer or sealer first.
  • Ensure the surface is level. Use shims if needed to create a flat mounting surface.
  • Clampsupport boards around the edges to hold the countertop level while the adhesive sets.

Taking time to correctly prepare the installation surface will allow the adhesive to fully bond and deliver optimum stability when learning how to stick quartz countertops.

Applying the Adhesive

With the surface prepped, it’s time to apply the adhesive. Be sure to follow all directions from the adhesive manufacturer. Here are some general tips when applying adhesive:

  • Lay down beads of adhesive or use a notched trowel to spread an even layer.
  • Focus on applying adhesive to the edges and corners for the strongest hold.
  • Don’t apply too much adhesive so that it oozes out when setting the countertop.
  • Only apply adhesive to areas that will have contact with the countertop, not the entire surface.
  • Be sure the adhesive fully covers the surface but doesn’t generate excess.
  • Allow the adhesive to become tacky before setting the countertop according to directions.

Applying the perfect amount of adhesive is key when learning how to stick quartz countertops for a solid bond. Taking the time to apply adhesive correctly will lead to proper adhesion.

Setting the Countertop

Once your surface is prepped and adhesive applied, carefully set your quartz countertop in place. Follow these tips when setting the countertop:

  • Have helpers to lift and position the countertop to avoid cracks or breaks.
  • Use a hand truck or cardboard to move the countertop if needed. Never drag quartz.
  • Slowly lower and settle the countertop into the adhesive. Do not drop.
  • Apply even pressure across the surface to create full contact with adhesive.
  • Use a J-roller across the entire counter to eliminate air pockets in adhesive.
  • Clean away any adhesive squeeze-out immediately according to directions.
  • Add additional supports or shims if needed to keep the countertop level.

Taking care when settling the quartz into the adhesive will generate the optimal bond when learning how to stick quartz countertops. Rushing this step can lead to cracks, uneven surfaces or future separation.

Allowing the Adhesive to Cure

Once your quartz countertop is in place, it’s crucial to allow the adhesive plenty of time to fully cure. Here are some guidelines for curing:

  • Avoid disturbing the countertop while adhesive cures for 24-48 hours.
  • Keep foot traffic and excess weight off the countertops during curing time.
  • Cure times may vary based on temperature, humidity and adhesive type.
  • Consult the adhesive directions for recommended curing methods and duration.
  • You may need to use tape or clamps to hold countertops in place while curing.

Letting the adhesive completely set up and cure is imperative when learning how to stick quartz countertops properly. Rushing this step or failing to allow full cure time can impede maximum adhesion.

Sealing Seams and Edges

Once cured, finishing touches like sealing all seams and edges will complete your quartz countertop installation.

  • Use 100% clear silicone sealant to fill any gaps along seams or edges.
  • Take care wiping away excess sealant for a neat finished appearance.
  • Allow sealant to fully dry for 24 hours before use.
  • Avoid harsh chemicals or abrasives on sealed areas.

Sealing all seams and edges properly waterproofs your countertops and prevents damage when learning how to stick quartz countertops correctly.

Avoiding Problems After Installation

To ensure your quartz countertops remain securely bonded for years, avoid these common issues after installation:

  • Prevent heavy impacts that can dislodge countertops like sitting or placing heavy items.
  • Use only approved cleaners and avoid abrasive pads. Harsh chemicals can degrade adhesive.
  • Don’t allow spills to sit. immediately clean any liquids to prevent moisture penetration.
  • Check for any partial separation or gaps appearing and re-adhere as needed.
  • Use cutting boards instead of cutting directly on quartz surfaces to avoid damage.

Being careful day-to-day and cleaning spills quickly will keep your investment pristine when learning how to stick quartz countertops successfully.

Learning the proper techniques for how to stick quartz countertops correctly will lead to a successful installation that looks beautiful for decades. Follow these tips and take care every step of the process for maximum results. With the right know-how, you can install quartz countertops like the professionals.

FAQ About Sticking Quartz Countertops

Many homeowners have additional questions when learning how to stick quartz countertops. Here are answers to some frequently asked questions:

How long does quartz countertop adhesive take to cure?

Most quartz countertop adhesives take 24-48 hours to fully cure. Always follow the manufacturer’s directions for recommended curing times. Avoid disturbing, cleaning or loading weight onto countertops during the curing period.

What’s the best way to transport a quartz countertop?

Always lift and carry quartz countertops vertically using adequate support. Never carry flat or drag edges to avoid cracks and breaks. Use hand trucks, cardboard or other methods to move quartz safely.

Do quartz countertops need to be sealed?

Unlike natural stone, quartz surfaces do not need regular sealing. However, sealing is recommended for seams and edges after installation to prevent moisture intrusion and damage. Use a clear 100% silicone sealant.

Can you install quartz countertops over existing countertops?

In most cases, existing countertops need removal prior to installing new quartz countertops. The surface must be completely clean and level to ensure proper bonding.

How thick should quartz countertops be?

Quartz countertops should be a minimum thickness of 2 cm or 3/4”. Thicker 3 cm countertops are recommended for heavier use areas. Only proper support and thickness will prevent bending or cracking.

What tools do I need to install quartz countertops?

A basic toolkit of safety gloves, adhesives, tape, silicone, J-rollers, shims, squares, saws and clamps will allow you to properly install quartz countertops following the techniques above.


Installing stunning quartz countertops yourself is entirely possible with the right preparation and process. By following essential steps like selecting quality adhesives, proper surface prepping, meticulous adhesive application, carefully setting countertops and allowing full curing time, you can achieve professional-looking results learning how to stick quartz countertops in your home.
