Why Adiseal Is The Best Professional Adhesive For 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 Results: 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 |
| Bond It PU18 | 582 psi | Bond Failed |
| Bond It Save Nails | 411 psi | Bond Failed |

High-Performance Features For Concrete Bonding
While the record-breaking strength is undisputed, Adiseal is engineered for professional environments where conditions are rarely perfect:
- All-Weather Performance: Weatherproof adhesive and waterproof sealant, suitable for working in dry, wet, and even underwater. This makes it an ideal adhesive for concrete pipe repairs.
- No Priming Required: As long as the surface is clean of dust, grease, paint, or dirt, priming or sealing of the concrete should not be required when using Adiseal to bond.
- Non-Staining: It does not stain or bleed into concrete, stone, or masonry, ensuring a clean, professional finish.
- High Gap-Fill: Adiseal has very high gap fill properties, useful where there are gaps between the concrete and item that requires bonding.
- High Initial Grab: Features strong initial grab, meaning temporary supports may not be required while the adhesive cures. For even higher grab, the Adiseal Hi-Grab product is available.
- Eco-Friendly & Safe: EC1 Plus certified (No VOC), making it suitable as an indoor and outdoor adhesive sealant for concrete and other materials. Adiseal is also ISEGA certified making it is safe for use in food preparation areas.
- Permanent Flexibility: Concrete expands and contracts with temperature changes. Adiseal stays flexible, preventing the bond from becoming brittle or snapping over time.
- Temperature Range: Effective in temperatures ranging from -40°C to +100°C.
Adiseal Adhesive Sealant vs. Adiseal Hi-Grab
While both products offer the same record-breaking final bond strength, choosing the right version depends on your specific concrete project:
- Adiseal (Standard): Best for applications where you need to move or “slide” the item into the perfect position before it sets. It has high gap-fill and is the best choice for general concrete bonding.
- Adiseal Hi-Grab: Best for heavy vertical items (like large stone wall claddings or heavy signs). It provides instant suction, usually eliminating the need for temporary supports or shoring while the adhesive cures.
Where To Buy
How To Attach Wood To Concrete
How to attach wood to concrete
- Minimise the Gap
Ensure the wood and concrete surfaces have an even contact area by cutting, filing, or sanding if necessary.
- Prepare the Surfaces
Both surfaces must be clean and free from dust, grease, or dirt. Use a fine paintbrush to remove fine concrete dust.
- Apply the Adhesive
Apply Adiseal in vertical strips, covering the bonding area.
- Position the Wood
Apply firm, even pressure to ensure good contact between the two materials.
- Clean Excess
Wipe away excess adhesive immediately with a cloth.
- Secure Temporarily (Optional)
If needed, use clamps or weights to hold the items in place while the adhesive cures.
- Allow to Cure
Give enough time for the adhesive to cure completely.
How To Bond Metal To Concrete
Adiseal is a high-performance metal-to-concrete adhesive ideal for attaching brackets, signs, or plates without the need for mechanical fixings.

Frequently Asked Questions About Concrete Adhesive
Adiseal is a top-performing adhesive for concrete bonding. It is independently proven as the strongest adhesive (exceeding 3123 psi) and offers a flexible, waterproof, and UV-resistant bond. Unlike traditional glues, it sticks almost any material to concrete without requiring a primer.
No, sealing is not required when using Adiseal. Because concrete is porous, it typically soaks up liquid glues, but Adiseal’s MS-polymer formula stays on the surface for a maximum bond. If you are using a thinner glue that requires a sealer, use Adiglue Activator.
A concrete adhesive is a specialized bonding agent designed to join materials to masonry. It works by creating a high-tensile chemical bond that penetrates the surface texture of the concrete, providing enhanced durability against vibrations and thermal expansion.
Yes, Adiseal can be applied directly to concrete. Ensure the surface is free of loose dust and “laitance” (the white powdery layer on new concrete) to ensure the adhesive makes direct contact with the solid substrate.
Yes, construction adhesive, like Adiseal, forms a strong bond with concrete surfaces, providing reliable adhesion for various applications.
Adiseal is the ideal choice for wood-to-concrete applications. It provides a permanently flexible bond that allows the wood to expand and contract without snapping the bond, making it superior to rigid epoxies.
Adiseal provides a record-breaking bond for stone-to-concrete projects. Because it is non-staining, it is safe for use with porous stones like marble, granite, and travertine, as it won’t bleed oils into the material.
Alternative Method: Mechanical Fixings And Drilling Concrete
While Adiseal provides a superior, flexible bond for most applications, it is also possible to attach items to concrete using mechanical fixings like screws or anchor bolts.
For quick, efficient drilling into concrete, brick, or other building materials, consider our high-performance Adiseal Ultimate drill bit. It is the fastest no-hammer masonry drill bit on the market, suitable for wood, metal, brick, and concrete.

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.
Summary Comparison
| 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.
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
Whether a glue for concrete is better to use or a concrete adhesive depends on the job type:
- Adiglue: Best if you have to bond items with a small surface area (e.g., repairing a small chip).
- Adiseal: Best if the items need a large surface area bonded (e.g., bonding a large block or wood panel).
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.
