3 SECURING THE DOLLY

3.1 USING 14.2mm OR 20mm 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
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 10 "Adhesives" on page 8
Note: If 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
3.2 TESTING ON CONCRETE USING 50mm DOLLIES
When testing 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
Note: 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 3.1, 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.
