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.
What is abrasive blasting/sandblasting?
Abrasive blasting (often referred to as sandblasting) is a fast and cost-effective method of surface preparation used for cleaning steel. It creates a roughened surface profile suitable for optimal adhesion for most coating systems including commercial strength paint for protective and aesthetic qualities. Impact cleaning of abrasive particles also removes mill scale, rust, paint, and other tough, brittle contaminants.
The performance of any paint coating is directly dependent upon the correct and thorough preparation of the surface prior to coating.
The most expensive and technologically advanced coating system WILL fail if the surface pretreatment is incorrect or incomplete. CCMP carry out both wet and dry abrasive blast cleaning strictly according to the specified standards as required for each project. A variety of abrasive media can be used to achieve the specified class of blast required for your individual project specifications.
