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. For any coating to perform successfully it is essential that the substrate is prepared properly.
Ensuring the correct surface preparation optimises the performance of the coating and material usage. Elcometer supply a range of products to meet each of the key industry standard surface preparation inspection methods, including surface condition, blasting parameters, surface profile, surface roughness and surface cleanliness.
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.
