Surface profile – or roughness – is essential for providing a “key” for coatings to firmly adhere to the substrate. However, excessive profile height can cause rapid coating failure, or at very least over consumption of paint.
Surface profile is affected by many factors including abrasive type, abrasive size, quantity of abrasive recycles, blast angle, nozzle distance, nozzle pressure, as well as substrate conditions.
