CAN ROUGHNESS TESTING BE CONDUCTED ON WET SURFACES?

No, for reliable results the test surface needs to be dry.

DOES A SURFACE NEED TO BE PRE-TREATED PRIOR TO ROUGHNESS TESTING?

We recommend conducting Roughness Testing on surfaces in the condition they ultimately will be applied in the production process. If this involves a pre-treated surface, it is also best to test it in its pre-treated condition. This is obviously not the case when it is tested as a guarantee for its pre-coating roughness.
