With any applied coating, the quality of the surface preparation is the most important factor in determining whether the coating will perform for its expected design life. With paint coatings in particular, almost all failures are due to poor surface preparation. Longer maintenance free performance is being demanded of protective coatings, and environmental and heritage issues increasingly impact upon surface preparation technology. The specification and quality assurance of surface preparation thus require as much attention as the priming and top coating systems. There are no shortcuts to good surface preparation and the costs of premature failure render the savings associated with cheap surface preparation insignificant. Extract from INGAL Specifiers
