Application
Non-destructive testing of the adhesive strength up to
2.2 N/mm² on surface to be tested (e.g. prior to the
application of a coat).
Preparation of the Test Area
• Clean and eventually scarify the floor surface (e.g.
cementious floor area).
• Stick the test disc (6) to the test surface and let the
adhesive glue harden (on cementious floor areas we
recommend a glue on the basis of Methylmetacrylat,
e.g. R21 from Silikal, Mainhausen, Germany).
• Screw the draw bolt (7) in the test disc (6).
(the area to be tested normally is not drilled for
non destructive testing).
Test Performance
• Hook the adhesive strength tester at the ball ended
draw bolt (7) and set in line with the draw spindle (14).
• Turn the wheel (13.1) clockwise until slight resistance
is encountered.
• Set the black pointer with the screw on the side wall of
the manometer (2) to zero, thus when the instrument is
unloaded.
• Turn the red tell tale pointer on the manometer (2)
anticlockwise up to the black pointer.
• Turn the crank (13.2) to load the sample up to fracture
or until the required value (maximum 2.2 N/mm²) is
reached.
• Read the value displayed.

Caution:
Do not overload the instrument. In case the
value of 2,2 N/mm² is reached no further
turning on the crank is allowed.
Maintenance of the Tester
• Keep the instrument clean and when not in use keep it
in the carrying case.
• Clean the thread of the draw spindle (14) occasionally
and oil it slightly. Therefor place the draw spindle (14)
at the highest position by turning the wheel (13.1) clock-
wise as far as possible.
• In case of oil leakage of the measuring system: Send
the instrument for repair.
Reuse of test discs (6)
The test discs (especially those made of steel) can be
used several times. For instance, when tested on a
cementious surface, the glue and plaster residuals can
be removed with hammer and chisel or by placing it on
a hot plate. The adhesive surfaces of the test disc (6)
should remain even (file if necessary).
Example of Application
The procedure for testing the adhesive strength
on a calcium sulphate bonded, cementious floor surface,
as it is performed in Germany, is described in the
enclosure.
