9 USING A DOLLY PLUG

Particularly in the case of low viscosity adhesives it is advisable to
place a nylon plug in the centre of the dolly before gluing it to the
surface.
This dolly plug stops glue going up the centre of the dolly, which can
impede the pin and prevent the test being carried out properly. Careful
cleaning of the centre hole increases the adhesion values for tests on
a given coating.
Each gauge is supplied complete with five dolly plugs. Additional plugs
are available to purchase separately, see Section 10.4 'Dolly Plugs' on
page 13.
To use the dolly plug:
1 Place the dolly plug through the centre hole on the dolly so that
the tip protrudes just below the test surface.
2 Apply the adhesive to the dolly test surface, see Section 4
'Securing the Dolly' on page 4, taking care not to get adhesive on
the plug.
3 Press the dolly and dolly plug onto the sample area for about 10
seconds.
4 Remove the dolly plug from the centre of the dolly and wipe the
end clean using tissue soaked in a suitable solvent. If the dolly
plug becomes stuck to the dolly, use pliers to remove it.
5 Complete the test as described in sections 5 to 6.
