Best adhesive for granite tiles
Choosing a High Quality Adhesive for Granite Tiles Choosing a quality adhesive to set granite tiles can be very important in ensuring that they last and hold together properly. A good adhesive will also provide long-term moisture and temperature resistance (the thermal expansion/contraction), which is important due to the dense nature of granite, the weight of the granite tile, and the minimal porosity of granite.
When considering what type of adhesive to use, you will need to consider the type of project being done (countertops, replacing and repairing existing tile installations, and bonding granite to other surfaces).
Regardless of the type of installation, there are two basic things that should be considered when choosing an adhesive: the bonding strength and flexibility of the adhesive, and the moisture resistance of the adhesive.
There are two general types of adhesives most commonly used for installing granite tile: Two-Component Epoxy Adhesives and Polymer-Modified Cement-based Adhesives.
Best Overall Product: Professional-Grade Epoxy Adhesive
Features:
(1) The highest bonding strength of any structural grade adhesive; excels in moisture and heat resistance.
(2) Can be used successfully for both interior and exterior applications.
(3) Very well-suited for heavy-duty granite tile installations, bonding joints, and repair work.
**Industry Insight**
A two-component epoxy adhesive has “unmatched bonding strength, moisture resistance, and heat resistance. This makes them the strongest choice for bonding structural granite.”
**Professional-Grade Epoxy Adhesive’s Best Applications:**
(a) Wet locations such as kitchens and bathrooms for granite tile installation;
(b) Bonding granite tiles that will be installed outside;
(c) Bonding joints of granite countertop installations;
(d) Bonding granite tiles that will have a high load applied.
Best Product for Installing Tiles: Cement-Based Tile Adhesive
Cement-based adhesive used for granite tile installations is an affordable, cost-effective adhesive used for installing granite tiles on floors and walls.- and epoxy-based adhesives/binding compounds differ in their bond strength with cement-based adhesives being a popular choice for installing tile over concrete as they provide good adhesion for bonding to concrete substrates.
Reasons for Using Cement-Based Adhesives for Tile Installation:
1) Cement-based adhesives specifically designed to adhere well with a cement-based substrate exist and work best in bonding tile to concrete substrates.
2) Cement-based adhesive provide excellent bond strength.
3) Cement-based adhesive are typically the least expensive, thus suitable for use in a home improvement projects.
Cement Adhesives Support Industry Research
According to industry research, the use of cement-based adhesives for bonding tiles consists mainly of granite tiles and that cement-based adhesives produce an excellent mechanical bond between tile and the granite (steel/cement to cement).
Cement Adhesive Limitations
Though cement-based adhesives may not be used for heavy duty applications and are best suited for interior construction of residential homes.
Best Applications of Cement Adhesive
1. Installing an interior floor with granite tiles.
2. Tiling the walls of a home.
3. General contractor projects.
Top Product Option for Small Scale Repairs:
*Cement Based Epoxy (Comparatively) Adhesive – A compact epoxy adhesive providing excellent adhesive strength for repairing chips, cracks, or small tiles made of granite/stone.
Product Benefits:
1. Excellent adhesion strength to chips, cracks, or small tile made of granite/stone.
2. Excellent adhesive strength and adhesion for home projects.
3. Available for both quick and long-term cure products.
Cement-Based Epoxy Adhesives for Industry Research
According to industry research epoxy cement-based adhesive products provide an effective solution for bonding chips, cracks and small bonding applications, such as.
Top Product Option for High Flexibility:
*Structural Product Adhesive – A high strength structural adhesive designed for bonding granite to other building materials (wood, metals, and concrete).
Reasons to Use:
1. Creating durable/strong bonds between many types of substrates.
2. Providing flexibility (thermal expansion/contraction) between granite and other building materials.
3. Providing multiple bonding/repair methods for granite to other building materials.
According to industry research, Structural Construction Adhesives provide the best solution for durable waterproof and flexible bonding of all types of granite and stone products.
Best Applications for Structural Construction Adhesives
1. Bonding granite to wood or metal.
2. Mounting granite wall panels.
3. Creating non-structural bonds using building products made of granite.

2) Grey Epoxy Adhesive for Tile Bonding
3) High Strength Epoxy Adhesive
4) Structural Construction Adhesive
Adhesive/Bonding Properties:
| Adhesives Type | Bonding Strength | H20 Resistant | Heat Resistant | Flexible | Best Utilization | Ease of Use | Cost |
|——–|—————–|—————-|—————–|———|—————|————–|—–|
| Epoxy A(High): Lapox Granito JR (5 Star) | Excellent | High | Low | Structural Bonding | Easy | Relatively High
| Epoxy B(Low): Xili Super Strong (3 Star) | Good | Medium | Medium | Tile Bonding | Moderate | Low
| Epoxy C(Low): Loctite PL Max (4 Star) | Excellent | High | High | Repair | Easy | Low
Adhesive/Bonding Selection:
1. Professional Installer – Use Cement-Based Adhesive (Low Cost); Due to Lower Cost and Required Bonding Strength
2. Heavy Duty Epxoy (High Cost or Low Cost) to Achieve Best Possible Strength and Durability for Exterior or Granite Installation
3. Small Repairs/Restorations – Use General Purpose Epoxy Adhesive
4. Bonding Granite to Other Materials (Wood, Metal, etc.) – Use a Structural Construction Adhesive (Very Flexible)
IMPORTANT:
1. Always Use A Neutral or Weakly Alkaline Adhesive to Eliminate Staining On Granite.
2. Clean And Remove Surface Material Prior To Bonding To Improve Bond Strength.
3. Allow a Minimum of 24 Hours Cure Time to Achieve Maximum Bond Strength for Any Epoxy Adhesive.
4. Do Not Use Silicone Adhesive (adhesives are not structural adhesives).
Final Recommendations:
1. Best Overall: Epoxy Adhesive (Provides Strongest Bonding Strength)
2. Best Tile Installation: Use Cement Based Adhesive
3. Best General Repairs: Small Packaged Epoxy Adhesive
4. Best Mixed Material Bonding: Use Structural Construction Adhesive
