Can I Glue Quartz Countertop with Gorilla Glue?

Installing a quartz countertop can seem intimidating, but with the right tools and techniques, it is very doable as a DIY project. When it comes to adhering the countertop, many homeowners wonder if they can use Gorilla Glue instead of the recommended adhesives. Here is a detailed look at using Gorilla Glue for quartz countertops.

What is Quartz Countertop?

Quartz countertops, sometimes called engineered stone, have become incredibly popular in recent years. They are made from ground quartz crystals combined with resins and pigments to create a durable, stylish, and low-maintenance surface.

Some key features of quartz countertops:

  • Extremely hard and scratch-resistant surface
  • Available in a wide range of colors and patterns
  • Non-porous so they don’t need to be sealed
  • Resistant to stains, burns, and etching
  • Easy to clean and maintain
  • Long-lasting with proper care

Quartz offers the look of natural stone without some of the hassles. It does not need to be sealed and is less prone to damage. This makes it an ideal choice for busy kitchens.

Can Gorilla Glue Be Used?

Gorilla Glue is a popular heavyweight adhesive known for its incredibly strong bond. But is it suitable for adhering quartz countertops?

The short answer is no – Gorilla Glue is not recommended for quartz countertop installation. Here are a few reasons why:

  • Gorilla Glue expands as it dries. This expansion can put stress on the quartz and lead to cracking or damage over time. The product is not designed to allow for the flexing that occurs in countertops.
  • It does not create a waterproof bond. Gorilla Glue forms a rigid bond. But quartz countertops need some flexibility and a waterproof seal to prevent moisture damage. Gorilla Glue cannot provide this.
  • The clamping time is too short. Gorilla Glue sets very quickly. This makes alignment difficult during quartz installation. You need more working time to position a countertop properly.
  • It can be hard to clean up excess adhesive. Any squeezed out Gorilla Glue is extremely hard to remove once dried. Quartz adhesives are made to clean up easily.

While Gorilla Glue creates an incredibly strong bond between many materials, it is not the right choice for adhering quartz countertops. The product characteristics do not align with the needs of a quartz installation.

Recommended Adhesive for Quartz

Instead of Gorilla Glue, installers recommend using a high-quality 100% silicone or polyurethane adhesive made specifically for quartz and engineered stone.

These adhesives have features important for proper quartz installation:

  • Flexibility – Allow natural movement without cracking.
  • Water resistance – Prevent moisture damage.
  • Long open time – Enable proper positioning and alignment.
  • Easy clean-up – Won’t ruin the surface when removing excess.

Popular quartz adhesive brands include Sika, LATICRETE, and DuPont. Always consult the countertop manufacturer’s recommendation and warranty requirements before selecting an adhesive.

Using the right adhesive designed for engineered stone makes installation much easier and prevents future problems.

Step-by-Step Guide to Installing a Quartz Countertop

Installing quartz countertops is best left to professionals, but determined DIYers can do it with proper planning and care. Here is a general overview of the process:

Gather Supplies

  • Quartz slabs
  • High-quality silicone or polyurethane adhesive
  • Trowel, roller, rags
  • Cleaning solutions
  • Support frame and braces

Prepare the Base Cabinetry

  • Ensure cabinets are level, secure, and clean
  • Build support frame sized 1/8″ less than quartz thickness
  • Cover walls and cabinets to protect surfaces

Dry Fit the Quartz Pieces

  • Carefully place quartz slabs in position
  • Check for proper fit and alignment
  • Make any necessary adjustments before final adhesion

Apply the Adhesive

  • Follow manufacturer instructions for spread rate and technique
  • Apply evenly across the entire surface
  • Use a roller to flatten and smooth adhesive

Set Quartz in Place

  • Carefully lower quartz into position
  • Apply even pressure to ensure full contact with adhesive
  • Use shims to keep quartz level as adhesive dries

Clean Up

  • Immediately wipe away any excess adhesive
  • Remove all temporary materials and coverings
  • Clean quartz surface as directed

Finish the Installation

  • Allow adhesive to fully cure per manufacturer timeframe
  • Complete final details like caulking and backsplashes
  • Enjoy your beautiful new quartz countertop!

FAQs about Gluing Quartz Countertops

Can you use silicone to install a quartz countertop?

Yes, 100% silicone adhesive designed for quartz/stone installation works very well. Be sure to follow the manufacturer’s instructions.

What adhesive is best for quartz countertops?

High quality silicone or polyurethane adhesives made specifically for engineered stone deliver the best results. Avoid Gorilla Glue and multi-purpose adhesives.

How long does quartz countertop adhesive take to dry?

Cure times vary by products but are generally 24-48 hours. Do not apply excess weight or stress before the adhesive has fully cured.

Can you install quartz countertop directly on top of laminate?

No, laminate is not a secure or smooth enough surface for direct quartz installation. Proper underlayment like plywood should be used.

What is the most durable adhesive for quartz?

Polyurethane-based adhesives tend to provide the strongest, most rigid bonds. Silicone also performs well with a bit more flexibility.


While Gorilla Glue may sound tempting for quartz countertop installation, it is not designed for this application. TheExpansion, rigidity, and other factors make it unsuitable for engineered stone adhesion. Investing in the proper silicone or polyurethane quartz adhesive will make a big difference in achieving a successful long-lasting quartz countertop installation. With care and patience, DIYers can tackle quartz countertop projects using the recommended flexible adhesives. Just remember to always consult the manufacturer’s guidelines before starting.
