Strongest Adhesive Independent Strength Test Results
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 |

| Extreme Temperature | Remains stable and effective from -40°C to +100°C. |
| Indoor Or Outdoor Use | Provides high quality bonds or seals in interior or exterior applications. |
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 adhesive sealant: 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
What Materials Does It Bond?
Adiseal is a universal MS polymer engineered to bond virtually most materials. It replaces the need for specialized wood glues, masonry adhesives, and plastic sealants.
| Surface Category | Compatible Materials | Professional Application |
|---|---|---|
| Masonry & Stone | Concrete, Brick, Granite, Marble, Slate, Limestone, Travertine | Ideal for paving, wall capping, and non-staining stone cladding. |
| Metals | Steel, Aluminum, Lead, Copper, Iron, Zinc | Perfect for gutter repairs, flashing, and structural metal-to-concrete bonding. |
| Plastics & Synthetics | PVC, ABS, Polycarbonate, Fiberglass, GRP, Polystyrene | Used for roofing sheets, window frames, and plumbing fixtures. |
| Wood & Timber | Hardwood, Softwood, MDF, Plywood, Chipboard | Provides a waterproof bond that won’t rot or weaken in damp environments. |
| Glass & Ceramics | Clear Glass, Mirrors, Porcelain, Tiles, Quartz | Securely bonds mirrors (non-corrosive) and kitchen/bathroom tiles. |
| Roofing Materials | Felt, Asphalt, EPDM, Bitumen, Shingles, Rubber (natural) | Instant emergency leak repair on major roofing substrates. |
Why Adiseal Bonds Better to Different Materials:
- Non-Porous Excellence: Unlike water-based adhesives, Adiseal cures via atmospheric moisture, allowing it to bond two non-porous surfaces (like metal to glass) effectively.
- Anti-Stain Technology: Many adhesives “bleed” oils into stone or marble. Adiseal’s chemically inert formula ensures zero migration into porous materials.
- Vibration Resistance: On materials prone to movement (like metal roofing or wood floors), Adiseal acts as a shock absorber, maintaining the bond during thermal expansion.
How To Use A Masonry Adhesive For Best Results
How to use a masonry adhesive
- Surface Preparation
Ensure that the surfaces to be bonded are clean, dry, and free from dust, debris, or any loose material. Use a wire brush or similar tool to remove any loose particles. Using a fine brush like a painting brush will help remove fine dust.
- Adhesive Application
Apply the masonry adhesive to one of the surfaces using the appropriate method. Covering more surface area with an adhesive can provide a better bond.
- Bonding Surfaces
Press the surfaces firmly together, ensuring proper alignment and contact. Apply sufficient pressure to create a strong bond. Adjust and reposition if necessary before the adhesive starts to set. Sliding the item side to side slightly can help spread the adhesive to cover more surface area.
- Temporary supports
Use temporary supports if the item does not stay in place until the adhesive has cured.
- Curing Time
Allow the adhesive to cure according to the manufacturer’s instructions. This typically involves a specified time for the adhesive to reach its full strength. Avoid disturbing or applying stress to the bonded surfaces during the curing process.
- Cleanup
Clean any excess adhesive immediately using a damp cloth or the recommended solvent, following the adhesive manufacturer’s instructions. It is easier to remove the adhesive before it fully cures.
Tip: To store Adiseal once opened, leave about 1cm worth of product out of the nozzle and store the tube upright in a cool dry place. Adiseal requires moisture for it to cure. The exposed part out of the nozzle will cure creating a cap. To re-use Adiseal, pull the cured part out or cut the nozzle until the uncured part is reached.
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 brick, concrete or other materials compared to the clear version.
Glue For Masonry
Masonry glue is specially designed for robust and lasting bonds in tasks involving bricks, stones, concrete blocks, and similar materials. It’s often used in construction for tasks like securing masonry veneers, repairing cracks or gaps in masonry structures, and assembling masonry elements.
Masonry glue is designed to endure significant loads and stresses prevalent in masonry projects. Its weather-resistant properties guarantee reliable and enduring bonds, making it suitable for various outdoor applications.
To ensure effective bonding, it is vital to prepare surfaces by thoroughly cleaning them of dust, debris, and loose materials. Apply the glue evenly, ensuring adequate coverage. Press the masonry materials together, allowing the glue to bond and set. Curing times may vary based on the product and environmental conditions, so following the manufacturer’s instructions is crucial for optimal results.
Adiglue glue for masonry
When using Adiglue glue on masonry, to avoid the masonry soaking up the glue, seal the masonry first before applying the glue.
For most bonding applications is is advisable to use the Adiseal adhesive and sealant over the Adiglue product. Adiseal adhesive and sealant will provide a stronger, more flexible and more durable bond on masonry.
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.
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.
