Adhesion Pull Off Testing
Verifying Bond Strength of Coatings, Screeds, Tiles & Adhesives

London Fixing Testing Ltd provides independent adhesion pull-off testing to assess the bond strength of coatings, screeds, tiles, and adhesive systems. Adhesion testing confirms that applied materials are securely bonded to their substrates and meet project, quality, and performance requirements.

What Is Adhesion Pull-Off Testing?

Adhesion pull-off testing is a controlled tensile test used to measure the force required to pull a bonded material away from its substrate. The test evaluates the quality of surface preparation, adhesive performance, and overall system integrity.

Adhesion testing is commonly required when:

  • Verifying bond strength prior to handover
  • Assessing surface preparation quality
  • Investigating bond failure or defects
  • Confirming compliance with specifications and standards

Our Adhesion Testing Services

We carry out adhesion pull-off testing on a wide range of materials and substrates, including:

  • Protective and decorative coatings
  • Screeds and levelling compounds
  • Tiles and tile adhesive systems
  • Resin flooring and bonded finishes
  • Concrete, masonry, and prepared substrates

Testing is performed using calibrated pull-off testing equipment, with dollies bonded to the test surface in accordance with relevant standards.

Standards & Compliance

Our adhesion pull-off testing is undertaken in line with recognised industry standards and guidance, including:

  • BS EN ISO 4624 – Pull-off test for adhesion
  • BS EN 1542 – Adhesion strength of repair products
  • Project-specific specifications and manufacturer requirements

Testing procedures and acceptance criteria are agreed in advance to ensure results are meaningful and compliant.

Clear, Detailed Reporting

Following completion of testing, we provide a comprehensive adhesion test report, including:

  • Material and system tested
  • Substrate type and condition
  • Test locations and preparation details
  • Pull-off strength results
  • Failure mode classification (adhesive, cohesive, or substrate)
  • Photographic evidence and observations

Reports are issued promptly to support quality assurance and project sign-off.

Frequently asked questions

What is adhesion pull-off testing?

Adhesion pull-off testing measures the bond strength between a material (such as a coating, screed, tile, or adhesive) and its substrate.

What materials can be tested?

Coatings, resin flooring systems, screeds, levelling compounds, tiles, tile adhesives, and bonded finishes.

Why is adhesion testing required?

It verifies surface preparation quality, confirms compliance with specifications, and helps identify causes of debonding or failure.

Is adhesion testing destructive?

Yes. Adhesion testing is locally destructive, leaving small test areas that can be made good after testing.

What standards are used for adhesion testing?

Testing is typically carried out in accordance with BS EN ISO 4624, BS EN 1542, and project-specific specifications.

What information is included in the report?

Test results, failure modes, substrate details, test locations, photographs, and engineer observations.

How quickly can testing be arranged?

We aim to respond quickly and can often attend site at short notice, subject to availability and project requirements.

What areas do you cover?

We provide testing services across London and the South East.
