5.2 TESTING COATINGS ON CONCRETE USING 50mm 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.
 Ensure 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.
2 Follow steps 1-4 in Section 5.1, 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.

6 ATTACHING THE GAUGE TO THE DOLLY

1 Ensure the quick connect coupling is fully
depressed.
2 Pull up the quick connect coupling, place
the actuator (with skirt fitted ) over the
dolly then release the coupling to grip the
dolly.
 The 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.
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.
