ABSTRACT:
A method is described for altering the surface of a virgin plastic moulding by impingement of plastic particles to render the surface suitable for the application of a coating. The coating will adhere and resist peeling better than with previous chemical surface preparation techniques. The method of the present invention calls for the use of graded granular plastic media material having a Barcol hardness between 20 and 80, propelled by compressed air or liquids or by mechanical means. The plastic media is totally recyclable such that by-products can be used in recycled markets.
