What condition can lead to cracking or alligatoring in coatings?

Not allowing sufficient drying time between coats can lead to cracking or alligatoring in coatings. This issue arises because when a coat is applied over a layer that hasn’t fully dried, the underlying layer may not have the necessary adhesion or stability to support the new coat. As the bottom layer continues to dry, it can shrink, causing the top layer to crack or create a pattern that resembles alligator skin.

Understanding this condition is crucial for proper coating application, as applying a subsequent layer on a still-wet surface interferes with the overall curing process and can lead to visible defects in the finish. Proper timing between coats is fundamental to ensure each layer sets appropriately, maintaining the integrity and appearance of the coating.
