3 SECURING THE DOLLY
3.1 14.2mm 20mmUSING OR DOLLIES
1 Prepare the surface of the dolly and the coating where the dolly is
to be applied by roughening with the abrasive pad. Then
de-grease and clean both surfaces using a suitable solvent and
allow to dry.
2 Mix equal quantities of the two part Araldite®adhesive and apply
a thin, even layer to the prepared surface of the dolly.
4Araldite adhesive is supplied by Elcometer however, other adhesives can
be used - see Section 12 ‘Adhesives’ on page en-12.
®
3 Press the dolly firmly onto the prepared test surface and apply
pressure to squeeze out excess adhesive which should then be
wiped clean.
4 Allow the adhesive to cure - see Section 12 ‘Adhesives’ on page
en-12.
4If testing on vertical surfaces, you may wish to tape the dolly in place
during cure.
5 If required, score the coating around the dolly using the dolly
cutter provided.

4 PREPARING THE GAUGE FOR TEST
3.2 50mmTESTING COATINGS ON CONCRETE USING DOLLIES
When testing coatings on concrete using 50mm dollies, scoring of the
coating down to, or into, the surface of the concrete may be required.
1 If testing on coatings thicker than
0.5mm (20mils) use the 50mm dolly
cutter and arbor (mounted in a drill
press or hand drill) to cut a “ring” into
the concrete.
2 Follow steps 1-4 in Section 3.1, making
sure the dolly is positioned inside the
cut “ring”.
To score coatings thinner than 0.5mm (20mils), a sharp knife may be
sufficient to carefully score around the dolly once it has been secured
in place by adhesive.
4Ensure that the scoring is perpendicular to the
coating and that the test area is not subjected to
twisting or torque. To minimise heat and
suppress dust, water lubrication may be
required.

Max Hold: The display holds the maximum value until the button

Note: “ ” will be displayed if the gauge zero has failed. This is due to the
pressure not being fully released from the instrument. If this occurs, release all
the pressure by turning the crank handle followed by the coarse adjustment

2 Pull up the quick connect coupling, place
the actuator (with skirt fitted ) over the
dolly then release the coupling to grip the
dolly.
b
1 Ensure the quick connect coupling is fully
depressed.
When testing at height or on vertical surfaces, in order to prevent damage to the
surrounding coating or harm to the user, it may be necessary to use the
Magnetic Anchor Clamp accessory, part number T99923797. This connects to
the lanyard ring on the top of the actuator to prevent the actuator from falling
when the dolly is pulled from the substrate.
3 Turn the coarse adjustment screw clockwise to apply a small
amount of pressure (approximately 1 - 2 a / 145 - 290psi), until
the actuator firmly grips the dolly.
MP
4 Rotate the crank handle clockwise to undertake the test - see
Section 6 “Performing the Test” for details.
4The quick connect coupling is not a bayonet
fitting. Do not attempt to push the actuator on to
the dolly without lifting the quick connect
coupling.

R
Do not exceed the maximum pressure as overloading could damage the gauge.
4The rate at which the force is applied
(the speed of rotation of the crank handle)
should be in accordance with the relevant
Standard.
(a) the coating fails and the dolly is removed from the surface
(destructive testing) or;
(b) the minimum specified pressure value is reached
(non-destructive testing)
2 Select the dolly size, see Section
9.4 on page en-9.
Continue until either;
4 Record the pressure indicated on the display and unwind the
crank handle and coarse adjustment screw.
(a)
3 Hold the gauge steady with one
hand and turn the crank handle
clockwise slowly and evenly to
apply an increasing force to the
dolly and hence stress to the
coating.

Note: Dollies can be reused after cleaning until either the top of the dolly where it is
held in position by the quick connect coupling is severely deformed or the dolly
surface is no longer flat. Additional dollies are available from Elcometer or your
local supplier - see Section 11.1 on page en-10 for details.

7()ASSESSING THE RESULTS DESTRUCTIVE TESTING
b) In some cases, the coating will cover only part of
the dolly face. A partial adhesion / coating failure should be
recorded if the coating covers more than 50% of the dolly face.
Partial Failure:
c) If no coating is present on the dolly this must be
recorded as a failure of the adhesive (or glue). This is normally
due to incorrect or insufficient mixing of the component parts of
the adhesive, incompatibility of the adhesive and the coating or
the dolly and / or test surface has not been properly prepared
before test - see Section 3 “Securing the Dolly” on page en-3.
Adhesive Failure:
Once pulled from the surface, examine the bottom of the dolly to
assess the results.
a) In most cases the coating will fully adhere to the
dolly and the test can be claimed as 100% valid.
Successful Test:
Cohesive Failure: When the coating fails in the body of the
coating layer leaving some coating on the surface and some
coating on the dolly face.
b)
a) c)
Observing the test area will give additional information about the type
of failure; adhesion and cohesion between different layers of the
coating.
When testing coatings on concrete it is common for the adhesive bond
between the coating and the concrete to exceed the strength of the
concrete itself. In this case concrete will be removed from the surface
and will be seen on the coating on the dolly face.
