It is important that a coating is applied to the correct thickness.
Applying too much wet coating will not only waste time and money,
but there is also a possibility of the coating cracking during the
curing process. Too little coating and there is a chance that the
substrate will not be sufficiently covered.
How to use it:
1. Select appropriate comb according to approximate known
thickness. 2. Hold comb perpendicular to surface coating to be measured. 3. Press into coating until the comb stands square on substrate. 4. Wet film thickness is between the highest step which is coated
and the next (higher) step which remains uncoated.
