Adiseal flexible adhesive is a high-performance products than provides a strong and durable bond on tile and many other materials. As it is flexible, it provides a non-brittle bond which makes it more durable than non-flexible adhesives. Adiseal has also been shown to be the strongest adhesive in an independent adhesive strength test.

Why use a flexible adhesive?
When bonding two items, it’s common for materials to undergo post-bonding movement, which can result from various factors, including:
- Temperature changes
- Vibration
- Moisture changes
- Wind
- Knocks
- Sound
- Expansion
- Contraction
Non-flexible adhesives become brittle as they harden, which raises the risk of adhesive failure. A brittle adhesive bond is prone to cracking, weakening over time, and eventually failing. In contrast, flexible adhesives can absorb stresses and joint movement without cracking, resulting in a more durable and resilient bond. They can accommodate the stresses placed on the adhesive.
Problems of using the wrong adhesive
Using a non-flexible adhesive when a flexible one is needed can lead to various problems:
- Lack of Joint Movement Accommodation: Non-flexible adhesives harden and become brittle, unable to withstand movement or stress, compromising the bond over time, potentially resulting in cracks, delamination, or failure.
- Structural Issues: When bonding materials with different expansion coefficients, like metal and plastic, non-flexible adhesives cannot adapt to varying rates of expansion and contraction, causing gaps, leaks, or disintegration.
- Inability to Withstand Environmental Factors: Non-flexible adhesives may not endure environmental conditions like temperature fluctuations, moisture, or vibrations. This can worsen the rigidity of the adhesive, leading to premature bond failure and potential assembly damage.
Choosing the right adhesive that matches the specific application requirements is crucial for ensuring lasting, reliable results. Using a flexible adhesive, in the video below, could have prevented the bond failure experienced with the non-flexible adhesive.
What is the best flexible adhesive?
To find out the strongest and best adhesive, Ultimate Handyman conducted a series of adhesive strength tests. The results were nothing short of impressive. Adiseal emerged as the indisputable best adhesive, demonstrating unparalleled strength that far surpassed all other competitor products. In fact, no other adhesive even came close to matching the incredible adhesive power of Adiseal with it being over 3 times stronger than the nearest competitor. Witness the astonishing test yourself in the video below.
The best adhesive was Adiseal
Adiseal’s adhesive strength significantly outperformed other grab adhesives, surpassing the competition by more than threefold. Such impressive strength led to the premature termination of the test. The force exerted by the hydraulic ram caused the screws securing the metal sheet to tear out, and even the hydraulic ram seal leaked, all before the Adiseal adhesive bond broke. Adiseal’s strength exceeded the capabilities of the test rig, solidifying its unrivaled dominance.
Strongest adhesive strength test results table
| Product | Max pressure when adhesive bond broke (psi) |
| Adiseal | 3123 + psi |
| SupaBond | 1115 psi |
| Tec 7 | 1016 psi |
| HB42 | 942 psi |
| Loctite PL Premium | 873 psi |
| Gorilla Grab Adhesive | 862 psi |
| Bond It PU18 | 582 psi |
| Bond It Save Nails | 411 psi |
“That is actually unbelievable!”

How to use a flexible adhesive
How to use a flexible adhesive
- Surface Preparation
Ensure that the surfaces to be bonded are clean, dry, and free from any dirt, dust, grease, or contaminants. Clean the surfaces thoroughly using an appropriate cleaner or solvent if necessary.
- Application
Apply the product evenly to one of the surfaces using a suitable applicator.
- Bonding
Align the surfaces to be bonded and carefully press them together, applying firm and even pressure. Make sure the adhesive spreads evenly between the surfaces, ensuring maximum contact.
- Curing Time
Allow the adhesive to cure as per the manufacturer’s instructions. This typically involves giving it sufficient time to dry and develop a strong bond. Keep in mind that curing times can vary depending on the type of adhesive used, environmental conditions, and the materials being bonded.
- Clean-Up
Remove any excess adhesive immediately using a suitable solvent or cleaner recommended by the manufacturer.
- Post-Cure
After the initial curing period, it is advisable to allow additional time for the adhesive to fully cure and reach its maximum strength. This may involve keeping the bonded item in a stable environment with optimal temperature and humidity conditions.
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.

Adiseal flexibility demonstration
The video shows the flexibility of Adiseal adhesive & sealant once it is cured.
In the video above, Adiseal bonded the bricks together, and even under repeated hammer strikes, the Adiseal flexible adhesive bond remained robust. Unlike standard adhesives that would fail under such force, Adiseal’s remarkable resilience is evident as it absorbs the hammer’s impact without breaking. This outstanding quality ensures a long-lasting, durable bond capable of withstanding severe impacts.
Flexible PVC adhesive
Adiseal is a robust and flexible adhesive perfect for PVC and other plastics, delivering strong bonds with PVC materials. Note that it may not be suitable for certain plastics like polypropylene or polyethylene. For maximum bond strength, thorough surface cleaning is essential. Adiseal is an excellent option for applications like PVC cladding, PVC trunking, PVC pipes, and other items demanding a robust and flexible PVC adhesive solution.
Flexible wood adhesive
Adiseal is exceptional as both a PVC and wood adhesive, forming strong bonds on various wood types, demonstrating its versatility in woodworking. For optimal bond strength, thorough cleaning of wood surfaces before applying the adhesive is essential. This step guarantees Adiseal’s durable and reliable bond, instilling confidence in any wood bonding project.
