Surface profile: The degree of profile on the surface affects a coating’s overall performance and determines aspects such as adhesion, coverage and overall volume of coatings used.
If the profile is too large the amount of coating required increases, otherwise there is a danger that the peaks remain uncoated - allowing rust spots to occur. If the profile is too small there may be an insufficient key for adequate adhesion.

Elcometer Guide to Surface Preparation
Surface preparation is one of the most important factors in the successful application of a coating or surface treatment and is critical to the effective lifetime of the coating.
