Paint and Surface PreparationWith poor surface preparation the expected design life of any coating will be significantly reduced. The demand for maintenance free protective coatings and low environmental impact paint removal technology are challenging a wide range of industries. Unfortunately there are no shortcuts to good surface preparation and sometimes the higher costs associated with preparation are becoming insignificant stacked up against premature coating failure due to cheaper preparation techniques. UHP water penetrates the oxide at the point of origin and lifts the cancer out of the profile but also decontaminates the surface of grease, oil and most importantly chlorides(salts) leaving a rust and contaminate free surface ready for paint application.
When comparing UHP water with dry abrasive blasting a number of factors need to be taken into consideration:
