The Truth About Paint Failure in Oregon: Battling UV and Moisture

The Truth About Paint Failure in Oregon: Battling UV and Moisture

Paint failure is common in Oregon due to our unique climate challenges. Understanding why paint fails helps you choose the right materials and prevent costly repaints.

Why Paint Fails in Oregon

Oregon's climate creates multiple challenges:

• **High humidity**: Promotes mildew and moisture absorption
• **Heavy rainfall**: Water intrusion through cracks and gaps
• **Intense UV exposure**: Fades and degrades paint
• **Temperature fluctuations**: Causes expansion and contraction

Common Paint Failure Types

Peeling

Caused by moisture behind paint, poor surface preparation, or incompatible paint layers.

Cracking

Results from paint that's too thick, poor surface preparation, or extreme temperature changes.

Fading

UV exposure breaks down pigments, especially on south-facing surfaces.

Mildew Growth

High humidity and lack of sunlight create ideal conditions for mildew.

Prevention Strategies

Proper Surface Preparation

• Thorough cleaning and scraping
• Sanding rough surfaces
• Repairing damaged areas
• Applying appropriate primer

Moisture-Resistant Primers

Essential for bare wood and high-moisture areas. Creates a barrier against water intrusion.

UV-Protective Paints

Premium paints with UV inhibitors resist fading and degradation from sun exposure.

Proper Application

• Multiple thin coats vs. one thick coat
• Proper drying time between coats
• Weather-appropriate timing

Choosing the Right Paint

For Oregon homes, look for:

• Moisture-resistant formulas
• UV protection
• Mildew resistance
• High-quality binders

We use premium paints specifically formulated for wet climates, including Sherwin-Williams Duration and Benjamin Moore Aura.

When to Repaint

Signs it's time to repaint:

• Extensive peeling or cracking
• Significant fading
• Mildew that won't clean
• Paint older than 7-10 years

Early repainting prevents costly surface damage.
