10 Best Concrete Adhesives 2025 in the United States

Gorilla 2 Part Epoxy is a strong choice for those needing a reliable adhesive for various materials. With a bond strength that can handle wood, metal, glass, and plastics, it’s versatile enough for tasks like wall repairs or furniture fixes. One of its standout features is the quick 5-minute set time, giving you ample opportunity to adjust and position your items before it hardens, making it user-friendly for both beginners and seasoned DIYers. The gap-filling capability is another highlight, allowing it to bond uneven surfaces and fill voids effectively.

The epoxy dries clear, which is a great advantage for projects where a clean finish is desired. Its water resistance means it can tolerate moderate exposure to moisture, making it suitable for various indoor and some outdoor applications.

There are a few drawbacks to consider. The 5-minute set time, while convenient, might not be long enough for larger projects that require more time for positioning items. Additionally, while it’s water-resistant, it isn’t fully waterproof, which may limit its use in very damp or water-heavy environments. The easy-to-use syringe design helps in precise application, but it’s worth noting that this product may not be the best choice for heavy-duty concrete bonding, as it’s primarily marketed towards lighter materials and repairs. If your project demands a more robust adhesive for heavy concrete applications, you might want to consider other options designed specifically for that purpose. Gorilla 2 Part Epoxy is an excellent adhesive for light to medium repairs and crafting projects, offering versatility and ease of use, but may fall short in more demanding concrete applications.

The 3M Hi-Strength 90 CA Spray Adhesive is a powerful, fast-drying glue designed to create strong, permanent bonds on concrete and various other materials like wood, metal, and plastic. One of its main strengths is its high bond strength and quick tack time, making it suitable for projects that require fast adhesion without waiting long for the glue to set. It comes in a spray form with an adjustable nozzle, which allows you to control the spray width for precise or broad application, which can be very handy depending on your project size.

This adhesive is moisture-resistant and can handle high temperatures, so it holds up well in environments where humidity or heat might otherwise weaken the bond. Another positive point is its low VOC content, making it safer to use indoors and more environmentally friendly compared to many other industrial adhesives. However, this product is intended for professional or industrial use, not consumer use, which suggests it might require proper handling and ventilation. Also, since it is a spray adhesive, it may not suit applications needing very thick or gap-filling glue.

Because the product’s permanent bond means repositioning after application is difficult, careful application is necessary. This adhesive represents a strong choice for those needing a reliable, fast-setting spray glue for concrete and similar materials, especially in professional or construction settings, though casual users should be cautious about its industrial nature and application method.

The DAP 7079860500 Concrete Crack Filler is a reliable option for repairing horizontal cracks in concrete, stone, and other masonry surfaces. One of its main strengths is its quick readiness for light foot traffic in just 4 hours and full service, including vehicles, in 48 hours. This makes it convenient for users who need a timely repair solution.

The product is easy to use with a ready-to-use formula that requires no shaking or mixing—just prep the surface, fill the crack, and mist with water. This ease of application will be appreciated by both DIY enthusiasts and professional users. Additionally, it resists shrinkage, UV fading, and further cracking, ensuring long-lasting repairs.

However, its maximum gap fill capacity is limited to 1/2 inch in width and depth, which may not be suitable for larger cracks. The product is waterproof and has good water resistance. It's a compact, 16 oz package, making it easy to handle and store. The DAP 7079860500 is a solid choice for small to medium-sized crack repairs, valued for its ease of use and durability.
