Fall has brought a change in weather, and this can often affect how your shop and paint behaves. So let’s review some Waterborne best practices to keep your shop at its most productive.

  • Confirm that you have clean, dry air being delivered to your spray gun. Less than 10% humidity is ideal.
  • Inspect booth filters, eliminate any dead zones or poor airflow by changing filters. A good target is 70-75 CFM. Sufficient airflow is key to proper performance of waterborne basecoat.
  • Use Adjuster and Modifier in every mix. This new technology has several benefits including the most robust film properties, a wider application window in humid conditions, and even improved metallic control.
  • Temperature affects viscosity. With the change in season, validate your standard reductions are giving you a spray viscosity of 23-28 seconds in DIN #4 viscosity cup.
  • Use vented spray cups to reduce pressure on the filter screen, which allows for a smooth constant flow of product (no spitting).
  • Fully dehydrate each basecoat layer with airflow over the repair. Airflow ensures evaporation pulls water from the substrate out. Avoid trapping water with heat, which dries from the surface inward.

These Waterborne best practices will help you work smarter not harder!
