2 TEST PROCEDURE
Operation of the gauge is a straightforward three-stage process:
1. Adhere dolly to coating
2. Attach gauge to dolly
3. Apply pressure and record result
2.1 ADHERE DOLLY TO COATING
1. Identify dolly test surface (Figure 1).
2. Ensure test surface of dolly is clear of old
adhesive. If necessary, remove adhesive as
detailed in “Clean the dolly” on page 8.
3. Wipe dolly test surface and sample area with a
solvent to remove oil and grease.
4. Apply a thin, even coat of adhesive to dolly test
surface. If adhesive is low viscosity refer to “Use of
dolly plugs” on page 9.
5. Press dolly on to sample for about 10 seconds.
6. Leave dolly undisturbed for at least 15 minutes
(preferably for 2 hours or more), to allow the
adhesive to harden.
7. If scoring of the coating around the dolly is required refer to “Cutting around the dolly” on page 11.
