ABSTRACT:
A method is described for blast cleaning paint and other adhesive coatings from composite surfaces formed of a reinforced matrix material. A special soft media is used at a relatively low pressure to prevent damage to the soft composite material. The preferred method calls for the use of a media having a Mohs scale hardness number of 3.0 or less. The media is pressurized to approximately 40 p.s.i. and directed at the composite surface to be cleaned. A method of optimizing the cleaning action is also described.
