Both during and immediately after abrasive blasting, atmospheric humidity levels are critical. This is due to the blasted substrate becoming vulnerable to flash rusting.

Introducing dehumidified air into an enclosed work area will help combat flash rusting. “Holding the blast” on uncoated, blasted steel for days — sometimes weeks is possible if the humidity is reduced to below 50% RH.

This typically will have a huge impact on a production cycle. Imagine being able to blast non-stop for a week before having to stop, clean up and paint!
