Definition

A pattern of interconnected cracks that resemble the scales of an alligator's skin. 

Basic Information

Alligatoring usually begins with inadequate surface preparation or unsuitable environmental factors before or during paint application, causing the newly applied paint to shrink while drying.

Common Causes

• New paint applied over an old, glossy finish without proper priming or sanding

• New paint was applied excessively thick

• New paint was applied in extreme temperatures

Progression

Over time, if left unaddressed, the cracks can deepen and spread, leading to more extensive damage to the painted surface. Factors like exposure to sunlight, moisture, and fluctuations in temperature can accelerate the progression of alligatoring. Eventually, the paint may begin to peel or flake off, exposing the underlying surface. Sometimes, even if it looks like the paint is protecting the surface underneath, it could actually be hiding algae or rot.

Solution

• Remove the paint by scraping or sanding it to the bare surface, or consider using a chemical paint remover. It's important to prioritize safety by wearing respirators and eye protection. If you opt for liquid removers, wear long sleeves and gloves.

• After removing the paint, thoroughly clean the surface to eliminate dust particles and allow it to dry completely.

• Finally, choose a high-quality paint or oil system to recoat and ensure a long life expectancy for this surface moving forward. Choosing the best paint/oil/finish will restore the appearance and enhance the durability and lifespan of the painted surface. Ensure the surface temperature is below 90ºF (32ºC) during and immediately after paint application.
