Introduction
Cracking or alligatoring paint is a clear sign that something went wrong. These patterns often look like reptile skin, with deep cracks forming across the surface. While it may appear to be a simple cosmetic issue, this type of paint failure often points to deeper problems related to preparation, product selection, or environmental stress.
At Schneider Painting, we regularly inspect exterior paint failures throughout Northwest Arkansas. This guide explains what causes cracking and alligatoring, how to spot early warning signs, and what prevents the issue from returning.
What Is Alligatoring Paint?
Alligatoring is a paint failure pattern where the surface cracks into large, irregular shapes. It often occurs on older homes or areas that have been painted multiple times.
Unlike fine hairline cracking, alligatoring indicates severe loss of flexibility in the paint film. Once this pattern appears, repainting without proper correction will not solve the problem.
-
Aging Oil-Based Paint Layers
One of the most common causes of alligatoring is old oil-based paint. Over time, oil-based coatings become brittle. As the surface expands and contracts with temperature changes, the rigid paint film cracks.
Many older Arkansas homes still have oil-based layers beneath newer paint. If not addressed properly, these layers eventually fail and cause cracking through the newer finish.
-
Applying Latex Paint Over Oil Without Proper Prep
Latex paint does not bond well to oil-based surfaces unless they are properly prepared. Without sanding and priming, the latex coating sits on top rather than bonding to the surface.
As temperatures change, the two paint layers expand at different rates, causing cracking and separation. Professional testing and preparation prevent this issue.
-
Thick Paint Application
Applying paint too thick is a frequent cause of cracking. Thick layers dry on the surface while remaining soft underneath. As the paint cures, internal stress causes the surface to split.
Exterior painting should always involve multiple thin coats. Schneider Painting follows manufacturer guidelines to ensure proper drying and curing between coats.
-
Moisture Trapped Beneath the Paint
Moisture is a major contributor to exterior paint failure. Water that enters siding, trim, or masonry pushes against the paint film as it evaporates.
Common moisture sources include:
- Leaking gutters or downspouts
- Poor drainage near the foundation
- Unsealed joints around windows and doors
- Painting before surfaces fully dry
Trapped moisture weakens paint adhesion and leads to cracking or bubbling.
-
Poor Surface Preparation
Paint cannot perform properly on dirty, chalky, or damaged surfaces. When old paint is not scraped, sanded, or cleaned, new paint bonds to unstable layers.
As those layers fail, cracking follows. Proper preparation removes weak paint and creates a stable surface for new coatings.
-
Temperature Extremes During Application
Exterior paint must be applied within specific temperature ranges. Painting in excessive heat or cold causes improper curing.
In hot conditions, paint dries too quickly on the surface. In cold conditions, it may not cure at all. Northwest Arkansas weather requires careful scheduling to avoid temperature-related failures.
-
Incompatible Paint Products
Not all paints work well together. Applying rigid coatings over flexible ones or mixing incompatible primers and finishes creates stress in the paint film.
Professional painters understand product compatibility and select systems designed to work together. Schneider Painting uses complete paint systems rather than mixing products randomly.
-
Wood Movement and Expansion
Wood siding and trim naturally expand and contract with humidity changes. If paint lacks flexibility, it cannot move with the surface.
High-quality exterior paints are designed to flex without cracking. Using interior paint or low-quality exterior products increases the risk of failure.
-
Multiple Layers of Old Paint
Homes that have been repainted many times may have excessive paint buildup. Thick layers reduce flexibility and increase stress during temperature changes.
In some cases, sanding or partial removal of old layers is necessary before repainting. Schneider Painting evaluates paint thickness and recommends corrective prep when needed.
-
Early Warning Signs to Watch For
Catching problems early can prevent major failure. Warning signs include:
- Fine surface cracks forming in straight lines
- Paint pulling away at joints
- Stiff or brittle paint texture
- Loss of elasticity when pressed
Addressing these issues early reduces repair costs.
How Professionals Fix Cracked or Alligatored Paint
Repairing cracked paint involves more than repainting. The proper process includes:
- Identifying the underlying cause
- Removing failed paint layers
- Repairing damaged surfaces
- Allowing surfaces to dry completely
- Applying correct primers
- Repainting with flexible exterior paint
Skipping steps results in repeat failure.
Why Local Experience Matters
Northwest Arkansas weather accelerates paint stress through humidity and temperature swings. Local experience helps painters choose the right products and timing for lasting results.
Schneider Painting understands these conditions and adjusts preparation and application accordingly.
