When choosing an adhesive, it’s important to consider factors such as the type of pavers being used, the condition of the concrete surface, and any environmental factors that may affect the adhesive’s performance. Proper surface preparation is also crucial, ensuring the concrete surface is clean, dry, and free from debris or contaminants.

Choosing the Right Adhesive

Choosing the right adhesive is crucial for creating a long-lasting and secure bond. With so many options available, it can be challenging to determine which adhesive is best for your project. Fear not. I’m here to guide you through the process of selecting the perfect adhesive for your pavers.

To begin, let’s explore the factors you need to consider when choosing an adhesive:

  • Type of Pavers: Different types of pavers require different adhesives. Natural stone pavers necessitate specialized adhesives specifically designed for bonding natural stone. Conversely, concrete pavers can be bonded using standard concrete adhesive.
  • Climate and Weather Conditions: If you live in an area with extreme temperature variations or frequent freeze-thaw cycles, selecting an adhesive that can withstand these conditions is vital. Look for adhesives labeled as freeze-thaw resistant or designed for outdoor use.
  • Surface Preparation: Prior to applying the adhesive, ensure that the concrete surface is clean, dry, and free from dirt, dust, or grease. Achieving a thoroughly clean surface may involve using a pressure washer or wire brush.
  • Setting and Curing Time: Consider your timeline when choosing an adhesive. Some adhesives have fast-setting times, while others require longer setting and curing periods. Factor in your project’s time constraints when making your selection.
  • Budget: Adhesive prices can vary significantly, so finding a balance between quality and affordability is important. Look for adhesives that meet your project needs without straining your budget.

Preparing the Surface for Adhesive Application

Preparing the surface for adhesive application is a crucial step in ensuring a strong and durable bond between pavers and concrete. To achieve this, there are several important steps to follow.

  • Clean the surface: Start by removing any loose particles from the surface using a broom or brush. For stubborn dirt or stains, a pressure washer can be used. It’s essential to have a squeaky clean surface free from any contaminants that might hinder the adhesive’s ability to bond effectively.

  • Repair cracks and uneven areas: Fill small cracks with a concrete patching compound. For larger cracks, it may be necessary to seek professional assistance. Additionally, level out any uneven areas using a self-leveling compound to create a smooth surface for the pavers.
  • Etch the concrete: Etching creates a rough texture on the surface, enhancing the adhesion of the adhesive. This can be done using an acid-based etching solution or mechanical methods such as sandblasting or grinding. Follow the manufacturer’s instructions for safety and effectiveness.
  • Rinse and dry: After etching, rinse off any residue left behind by the etching solution and let the surface dry completely. Moisture can interfere with the adhesive’s ability to bond, so ensure a dry surface before moving forward.
  • Prime the surface: Primer promotes adhesion and ensures a stronger bond between the pavers and concrete. The type of primer will depend on the adhesive being used, so follow the manufacturer’s recommendations. Apply the primer according to instructions and allow it to dry completely before proceeding with adhesive application.

Using Mechanical Fasteners with Adhesives

Today, we’ll explore the dynamic duo of mechanical fasteners and adhesives, a match made in paving heaven. Whether you’re transforming your backyard oasis or embarking on a grand-scale project, this powerful combination ensures that your pavers will remain steadfast for years to come.

Congratulations. You’ve reached the pinnacle of your installation journey. Now, grant your pavers the gift of time to cure before subjecting them to their ultimate destiny. This final step ensures an unyielding foundation that can withstand any challenge life throws at it.

Factors to Consider When Choosing an Adhesive

When it comes to sticking pavers to concrete, the adhesive you choose can make all the difference. It’s essential to select an adhesive that provides a strong and durable bond, able to withstand heavy foot traffic and challenging weather conditions. So, what factors should you consider when selecting an adhesive for this purpose? Let’s explore the key factors that will empower you to make an informed decision.

Bond Strength:

The bond strength between the pavers and the concrete surface is of utmost importance. Look for adhesives specifically formulated for paver-to-concrete applications with high bond strength ratings. This ensures that your pavers remain firmly in place, even under constant pressure or in extreme weather conditions.


Adhesives come in various formulations designed for specific materials. Consider the compatibility of the adhesive with both the pavers and the concrete surface. This ensures proper adhesion without risking potential damage or bond failure. Seek recommendations from manufacturers or experts regarding adhesives suitable for your specific paver and concrete materials.


Concrete surfaces expand and contract, while pavers may shift slightly over time. To accommodate these movements without compromising the bond, opt for flexible adhesives. Polyurethane-based adhesives, renowned for their flexibility, are a popular choice for paver-to-concrete applications.

Weather Resistance:

Outdoor pavers face constant exposure to varying weather conditions. Select an adhesive that is resistant to UV rays, moisture, heat, and cold. This ensures that the bond remains intact and reliable over time, regardless of the environmental challenges it encounters.

Ease of Use:

Consider your skill level and available resources when choosing an adhesive. Some adhesives require special tools or equipment for application, while others may have specific instructions or curing times. Choose an adhesive that suits your needs and guarantees a smooth and efficient installation process.

Environmental Impact:

In today’s world, eco-friendly options are gaining popularity. Look for adhesives with low volatile organic compounds (VOCs) and minimal toxic emissions. By choosing environmentally friendly adhesives, you not only contribute to a healthier environment but also create a safer living space for those using the paved surface.


While cost is a significant consideration, it should not be the sole deciding factor. Strike a balance between cost, quality, and durability. Investing in a high-quality adhesive may incur a higher initial expense, but it will save you money in the long run by providing a longer-lasting bond.
