Allow the adhesive to cure - see Section 15 ‘Adhesives’ on page 21.
If testing on vertical surfaces, you may wish to tape the dolly in place during cure.

If required, score the coating around the dolly using the dolly cutter provided.
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 0.5 mm (20 mils) 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
4
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 0.5 mm (20 mils), a sharp knife may be suf ficient to carefully score around
the dolly once it has been secured in place by adhesive.

1
Pull up the quick connect coupling, place the actuator (with skirt fitted ) over the
dolly then release the coupling to grip the dolly.
4
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.

Skirts for 10mm, 14.2mm, 20mm and 50mm dollies and thin substrates are available - see Se
etails.
