What Glue Do You Use for Quartz Countertops?

Quartz countertops are a popular choice for kitchen and bathroom remodeling projects thanks to their durability, low maintenance, and stylish appearance. When installing quartz counters, proper adhesive selection is crucial for creating a long-lasting bond and preventing cracks or damage over time. Here is an in-depth look at the best glues to use when installing quartz countertops.

An Overview of Quartz Countertops

Quartz countertops, sometimes referred to as engineered stone, are made from ground natural quartz crystals combined with polyresin binders. The result is a non-porous, highly durable surface that resists scratches, stains, and heat damage better than natural stone.

Some key advantages of quartz counters include:

  • Highly durable and long-lasting
  • Requires very little maintenance
  • Resists stains, scratches, and heat damage
  • Available in a wide variety of colors and patterns
  • Non-porous so does not require sealing

Quartz is an excellent choice for heavy use areas like kitchens and baths. Proper installation with the right adhesive is important to create a permanent, seamless countertop that will last for many years.

Why Using the Right Glue Matters

Choosing the correct adhesive is a critical step when installing quartz countertops. The right glue will create a strong, permanent bond between the countertop and cabinet base. The wrong adhesive can lead to a weak bond that allows movement, cracks, or even total countertop failure over time.

Here are some of the risks of using the wrong glue for quartz counters:

  • Weak bond: Countertop separates from base leading to cracks and gaps
  • Flexing: Allows movement which causes cracking long-term
  • Difficulty cleaning up: Low quality glue squeezes out and sticks
  • Damage: Allows moisture underneath leading to swelling

Luckily, selecting the right adhesive is easy if you know what to look for. The ideal glues for quartz feature high bond strength, some flexibility, and are specially formulated for solid surface materials.

Recommended Adhesives for Quartz Countertops

The three main types of adhesive recommended for quartz counters include:

1. 100% Silicone Adhesive

100% silicone provides an incredibly strong, permanent yet flexible bond. This adhesive adheres well even on non-porous surfaces like quartz. Key features:

  • Specifically designed for solid surfaces
  • Strong flexible bond won’t crack
  • Allows slight movement without compromising bond
  • Long working time for adjustments
  • Easy cleanup with mineral spirits

Popular brand: Dow Corning 790 Silicone Building Sealant

2. Acrylic-Based Adhesives

Acrylic latex adhesives create a permanent bond and allow some flexibility. They offer a long open working time and are easily cleaned with water while wet. Features:

  • Designed for solid surface materials
  • Permanent flexible bond
  • Easy water clean-up when wet
  • Long open time for adjustments

Popular brands: Franklin 1883 Acrylic Adhesive, Loctite PL Premium Polyurethane Construction Adhesive

3. Epoxy Adhesive

Two-part epoxy adhesives provide an extremely rigid and permanent bond. Epoxies are more difficult to work with and offer less flexibility compared to other options. Benefits include:

  • Extremely rigid permanent bond
  • High bond strength
  • More difficult to work with
  • Less flexibility than silicone or acrylic

Popular brands: Gorilla 2 Part Epoxy, Loctite Epoxy Heavy Duty

Tips for Gluing Quartz Countertops

Follow these best practices when gluing quartz counters for flawless results:

  • Ensure all surfaces are clean, dry, and free of debris
  • Apply adhesive to the cabinet base, not the quartz underside
  • Use a notched trowel to evenly spread a thin layer of glue
  • Create support along the front edge with adhesive and brackets
  • Gently set the countertop in place and press down firmly
  • Wipe away any squeezed out adhesive immediately
  • Allow the glue to cure fully before use per manufacturer directions

FAQ About Gluing Quartz Countertops

What glue do you use for quartz countertops?

100% silicone adhesive, acrylic latex adhesives, and two-part epoxy are recommended for quartz. Silicone provides the best bond with flexibility.

How long does it take for quartz countertop adhesive to dry?

Drying times vary by adhesive used. Silicone and acrylic adhesives typically take 24-48 hours to fully cure. Epoxies take 5-12 hours to cure completely.

Should you use silicone or epoxy for quartz countertops?

Silicone is preferred for the flexible yet strong permanent bond it creates. Epoxy forms a more rigid bond and is harder to work with.

What is the best quartz countertop sealer?

Quartz does not require sealing due to its non-porous surface. If sealing is desired for added protection, an impregnating sealer is best.

How do you secure a heavy quartz countertop?

Along with quality adhesive, use metal brackets for long-term support. Apply adhesive and brackets along the front edge where counters overhang.

Can you reuse quartz countertops if removed?

It is very difficult and unlikely that quartz counters can be removed and reused due to the permanent adhesive bonds. The countertops would likely crack or break.


Installing new quartz countertops using the proper adhesive is critical to creating counters that will last for the long-haul. Be sure to use a bonding product designed specifically for solid surface materials like quartz. 100% silicone sealants provide the best adhesive solution for permanent flexibility and strength. Carefully follow adhesive directions and best practices for a seamless quartz countertop installation. With the right glue and technique, you can enjoy beautiful, durable quartz counters that will last for many years in your kitchen or bath.
