Paint Alligatoring - Causes & Solutions

Learn how to avoid paint alligatoring and discover how easy it is to create smooth, crack-free surfaces. When a new paint job cracks, it is called alligatoring . Alligatoring is also known as crazing. This results from several sources, and in each instance, is preventable.

Causes

Alligatoring results from a lack of elasticity within a paint layer. This happens when the initial coat of paint is applied without allowing the primer to fully dry. Do not let the excitement of completing a project cause you to rush the process. Take your time, let each layer dry. Alligatoring paint can also occur when you use incompatible forms of products. Glossy paints or enamels do not work well when applied to a latex paint. Sometimes paint alligatoring happens when oil-based paints are exposed to fluctuating temperatures. Oil-based paints provide little elasticity and don't usually work well in an outdoor environment without proper preventative measures.

Solutions

Repair alligatoring by thoroughly removing all coats of paint, using chemical paint removers and sanding. Re-apply your primer and allow it to dry before putting on the best paint for your job. Consider latex-based paints because they have great elasticity and durability. Avoid using latex-based paints with oil-based products. Let each layer dry thoroughly. Let it dry for four hours, at least. A longer period may be needed, depending upon your weather conditions.

The causes and solutions of paint alligatoring are simple. With the right paint and application, your paint job can be enjoyable for years to come. The main key to a successful painting experience is taking your time. With the right combination of paints and technique, paint alligatoring is a thing of the past. Learn the right proceedure before you tackle that next painting task and enjoy a smooth, beautiful paint finish every time.
