Adhesive Strength Test

In a construction adhesive strength test conducted by Ultimate Handyman, various leading adhesive brands underwent a rigorous challenge using a hydraulic ram. The task involved applying each adhesive between wood and metal surfaces and measuring the breaking point after curing.

Adiseal emerged as the standout performer, stealing the spotlight with a bond strength that exceeded the closest competitor by an impressive 300%! The sheer strength of Adiseal not only outshone the competition but also exerted such force that it caused the test rig itself to fail. The pressure from the hydraulic ram led to the screws of the test rig ripping out before the adhesive could break.

This unexpected outcome vividly highlights Adiseal’s unparalleled adhesive capabilities. Despite the need to halt the test for the rig’s safety, it unequivocally establishes Adiseal as:

Over 3 times stronger than its closest competitor

Possessing a bond so robust that it surpassed the limits of the test rig.


Strongest grey adhesive proven by an independent test.


Test results

In independent adhesive bond tests conducted by Ultimate Handyman, Adiseal demonstrated remarkable strength, surpassing all other adhesives. While competitor products reached breaking points at or below 1115 psi, Adiseal exhibited exceptional resilience, enduring pressures that exceeded 3123 psi. The accompanying chart vividly illustrates Adiseal’s unparalleled performance.

  1. Prepare the Surfaces

    Ensure that the surfaces to be bonded are clean, dry, and free from dust, grease, or debris. Thoroughly clean the surfaces using a suitable cleaner or solvent.

  2. Apply the Adhesive

    Apply a thin, even layer of the grey adhesive to one of the surfaces you intend to bond, ensuring comprehensive coverage for a better bond.
