What is a Pull Off Tester?

A Pull Off Tester is a laboratory testing machine used to evaluate the bond strength between two materials. During the test, a steel or aluminum loading disc (dolly) is bonded to the specimen surface using epoxy adhesive. The tester then applies a controlled tensile force perpendicular to the surface until failure occurs.

The measured maximum force determines the tensile bond strength of the material and helps identify whether failure occurs within the substrate, adhesive layer, coating, or interface.

This test is widely used for:

  • Concrete structures
  • Repair mortars
  • Tile adhesives
  • Surface coatings
  • Plaster systems
  • Waterproofing membranes
  • Thermal Insulation Composite Systems (ETICS)
  • Industrial flooring
  • Bridge and tunnel rehabilitation
