Our high pressure surface preparation equipment and systems operate at pressures up to 3,000 bar without any abrasive additives. Using water eliminates the harmful and often damaging side effects produced by dry abrasive blasting such as airborne dust, chemical/thermal pollution and surface ingrained residual blasting materials. Waterjetting is the healthy, environmentally friendly method of surface preparation.
Substrates prepared by our surface prep systems meet the quality requirements set by international paint manufacturers and standards authorities for the application of new coatings. The water pressure necessary depends upon the condition of the existing surface layer(s), the type of coating to be applied and the substrate quality necessary for the successful application of that coating. The energy of the high velocity water jets blast into the pores in the metal surface flushing out solid foreign matter and non-water soluble pollutants such as oil and grease. Remaining chloride levels are at least five times lower than in a grit-blasted surface and the substrate profile remains intact ensuring good adhesion of the new coating and greatly reducing the risk of future paint film defects.
The amount of waste produced is far less than that produced by dry blasting. The waste water, old paint, marine growth and rust are easily collected for separation and disposal. Water can be treated for disposal or recycling. Shrouding the work area is not necessary. Water will not harm nearby equipment and machinery as is often the case with the ingress of flying grit particles. Nor is there any unhealthy dust to distress yard personnel.
