Surface Preparation & Coating

Surface Preparation & Coating

Ice blasting does a superior job preparing surfaces for painting. Our system is the most aggressive system in the world. We blast at 350 psi (24 bars) which ensures that all loose paint is removed from the surface and further paint failure will not occur underneath the new coating. Also, the dry ice particle penetrates any pores or crevices on steal surfaces, thereby removing any possible contaminant. Ice blasting removes all microorganisms (see below study) and oils as well which can contribute to paint failure if they are not removed. Collectively, these characteristics of ice blasting provide the cleanest possible surface for applying a coating. Coatings can be applied immediately after the surface is ice blasted because it is completely clean and dry. If the surface is already wet, ice blasting will dry out the wet surface. Our technology creates the best surface for the paint to bond, therefore, providing the greatest longevity for the paint’s lifespan.

Our system is completely self-contained and we don’t use any of your utilities and won’t bother your company for any support once we get started. Our company is the ONLY ice blasting contracting company that manufactures their own equipment. We are very specialized and understand what it takes to get the best results when preparing a surface for recoating and our results can only be achieved with our specialized equipment. The high pressure we generate creates the deepest clean possible allowing for the cleanest possible surface for recoating.

Coating Adhersion Testing

A piece of heavy equipment was surface prepared using dry ice and a coating was applied immediately following the blasting. After curing the coating was tested and the results are below.

This test was performed in accordance with ASTM D3359 -Adhesion by tape test, method A (X cut) The results were consistent with rating 5A-no peeling or removal. Duct tape was used for this test, since it was available and has a tenacious bond when compared to other commonly available options.

CRYOBRASIVE™ BLASTING

When a substrate is heavily corroded or if a profile is needed for a particular coating, additional steps are taken to further mitigate the deterioration. First, a dry ice blast will be performed to provide a clean substrate. Once the substrate is cleaned, we determine areas that may not have an anchor profile and address those areas with a dry ice / garnet cryobrasive™ solution.

This is very beneficial as a minimal amount of abrasive needs to be added to the dry ice so you are left with very little dust, clean up, or disposal. A near white metal surface is still created and an anchor profile is achieved which is typically between a 1.5 to 2.5 mils. The benefits to this process are a dramatically reduced amount of abrasive, the cleanest possible surface, and an anchor profile achieved.

Traditional methods would be a straight abrasive blasting which would result in truckloads of abrasive and debris to remove afterwards. On average we can reduce waste by a minimum of 90% and upwards to 99% depending on deterioration levels. Any areas of coating remaining are considered a sound solid substrate and acceptable to receive a new coating.
