What’s the Deal with Orange Peel?

Application issues:

• The roller was not suitable to be rolled, had the wrong size nap roller sleeve, or was used incorrectly.
• The finish or sealer was overworked on the application surface, resulting in the formation of air bubbles within the applicator, which caused incomplete flowing out of the finish.
• The finish was not applied according to the manufacturer’s recommended coverage rate and was either too thin or too thick.
• The manufacturer’s recommended solvent additives or dry-time-extending retarders for unfavorable coating conditions were not used.

Environmental issues:

• The finish flashed-off too quickly due to hot, dry conditions.
• The finish dried too slowly due to cool, damp conditions.
• The finish or substrate was too cold at the time of application, which caused uneven flow and leveling.
• The surface of the finish was skinned or otherwise disturbed by airflow.

Once you discover those dreaded dimples, your only option is to abrade the surface and then recoat. A full resand may also be necessary in some cases. There are, however, a few steps that you can take to make sure your recoat bears fruit:

• Confirm that you’re using the recommended roller with the correct size nap roller sleeve, and make the switch if you’re not.
• Work at the spread rates appropriate for the finish as suggested by the manufacturer.
• Verify that the product has adjusted to the proper temperature prior to application.
• Ensure the conditions of the jobsite are optimal with respect to temperature, moisture, airflow, etc., consulting with the finish manufacturer as needed.
• If necessary, utilize the proper solvent additives or dry-time-extending retarded.
