Concrete Adhesive
What is the Best Adhesive to Glue to Concrete?
For the best concrete adhesive, Adiseal is the strongest adhesive, proven in independent testing by Ultimate Handyman. Withstanding 3123+ psi without breaking, Adiseal is over 3X stronger than competitor products.
This professional-grade MS-polymer provides a heavy-duty, durable, flexible, waterproof bond on concrete and other construction materials like metal or wood. Adiseal features high gap-fill, UV-resistance, works in dry or wet conditions, and is suitable for both indoor or outdoor use.
What Is The Strongest Adhesive For Heavy-Duty Concrete Bonding
While various construction glues can bond to masonry, most fail under extreme stress or moisture. Adiseal construction adhesive sealant stands apart by maintaining a high-tensile bond where traditional grab adhesives fail. Its MS-polymer formulation ensures that the bond remains permanently flexible, preventing the ‘brittleness’ often seen in standard adhesives when exposed to concrete’s natural alkaline properties and thermal expansion.
Independent Strength Test Performance: Adiseal vs. Competitors
To verify our performance claims, we look to independent testing conducted by Ultimate Handyman. In a controlled environment, various construction adhesives were tested to find the maximum pressure they could withstand before the bond failed. Adiseal was the only product to exceed 3123+ psi, at which point the test was forced to stop because the testing rig itself began to break.
| Product Name | Max Strength (PSI) | Test Result |
|---|---|---|
| Adiseal | 3123+ psi | Bond Unbroken (Test Abandoned) |
| SupaBond | 1115 psi | Bond Failed |
| Tec 7 | 1016 psi | Bond Failed |
| HB42 | 942 psi | Bond Failed |
| Loctite PL Premium | 873 psi | Bond Failed |
| Gorilla Grab | 862 psi | Bond Failed |

Adhesive vs. Concrete Bolts/Screws
When choosing between a concrete adhesive like Adiseal and mechanical fasteners (bolts/screws), the decision rests on permanence versus removability and immediate strength.
Adiseal Adhesive: The Permanent, Flexible Choice
Adhesive bonding provides a superior, long-term solution by distributing stress evenly across the entire surface.
- Key Benefits: Permanently flexible (accommodates concrete expansion/contraction), acts as a waterproof sealant to prevent corrosion, and avoids the localized stress points that cause concrete to crack.
- Best for: Permanent installations, demanding long-term durability, waterproofing, and situations where a clean, invisible finish is required.
Mechanical Fasteners: The Immediate, Removable Choice
Fasteners like bolts and screws are effective when immediate strength and the ability to disassemble are required.
- Key Benefits: Offer immediate load-bearing capabilities as they need no curing time, and installations are easily removable or adjustable.
- Best for: Temporary fixes, immediate load requirements, or non-critical applications where removability is a priority over long-term flexibility and waterproofing.
Comparison: When to Use Concrete Adhesive vs. Mechanical Bolts.
| Feature | Adhesive (Adiseal) | Mechanical Fasteners |
|---|---|---|
| Load Distribution | Evenly distributed | Concentrated stress points |
| Flexibility | Permanently flexible | Rigid |
| Curing Time | Requires 24-48 hours | Immediate loading |
| Waterproofing | Yes, acts as a sealant | No |
| Removability | Permanent bond | Easily removable |
For most heavy-duty applications, the long-term durability, flexibility, and sealing properties of Adiseal make it the superior choice over rigid mechanical fixings.
Flexible Adiseal Adhesive vs Rigid Concrete Epoxy
Adiseal offers a high-strength concrete epoxy alternative that avoids the cracking associated with rigid resins. While traditional epoxy is brittle, Adiseal’s permanently flexible MS-polymer formula absorbs vibration and thermal movement. This makes it a more reliable, weather-resistant choice for both indoor and outdoor structural bonding.
Colours
Adiseal adhesive and sealant is available in the following colours:
- White adhesive and white sealant
- Black adhesive and black sealant
- Grey adhesive and grey sealant
- Clear adhesive and clear sealant
- Brown adhesive and brown sealant
Adiseal can also be manufactured in any RAL colour.
Please note Adiseal adhesive sealant colours provide a stronger bond on concrete and other materials compared to the clear version.
Concrete Demonstration Block
In the image above, we showcased various materials bonded to concrete using Adiseal. Unlike competitor adhesives, no primer or sealer was required on our concrete demonstration block. We simply cleaned the surface of the concrete block thoroughly before applying the adhesive.
Glue For Concrete
If you’re looking for a glue specifically designed for gluing materials to concrete, our Adiglue glue is a suitable option. While Adiglue offers greater flexibility and strength compared to super glues, it is still not as flexible or strong as our Adiseal construction adhesive & construction sealant.
In the image above, we bonded a metal handle to a concrete slab with Adiglue. Before gluing, we sealed the concrete with Adiglue Activator to prevent glue absorption. However, Adiseal construction adhesive sealant doesn’t require concrete sealing for the same purpose.
Glue For Concrete vs Concrete Adhesive
While people often search for “concrete glue” when they need a quick fix and “concrete adhesive” for construction, Adiseal bridges the gap by providing the ease of a glue with the strength of a structural adhesive.
- Adiseal (Heavy-Duty Concrete Glue): Use this for 95% of projects, including bonding wood, metal, or stone to concrete. It is a gap-filling “glue” that doesn’t require the concrete to be sealed first.
- Adiglue (Precision Concrete Glue): Best for small-surface area repairs (like fixing a small chip in a concrete statue). Note: This thinner glue requires Adiglue Activator to prevent the porous concrete from soaking up the liquid.
Secure Your Project With The Strongest Concrete Adhesive
Don’t settle for brittle bonds or adhesives that fail in wet conditions. Whether you are bonding heavy stone, metal brackets, or timber panels to masonry, the 3123+ PSI record-breaking strength of Adiseal ensures a permanent, flexible, and waterproof result.
