Bristle Blasting as a Method for Surface Preparation

It has been generally recognised that the best method of surface preparation in maintenance situations allowed by either regulation or situation is either grit blasting or even UHP (hydroblasting).  Hand tool and power tool preparation has always been regarded as methods which will afford poorer surface preparation standards and therefore reduced lifetime of the maintenance coating.  However, a new method of surface preparation has been introduced which takes aspects of both; the portability and easy handling of the power tool equipment and the achievable cleanliness and surface profile of the blasting equipment.  This paper details this method of preparation and the performance comparison of various standard maintenance products across various accelerated test methods.
