How Humidity Affects Paint in the Midwest

The Risks of Mold, Peeling, and Blistering

Humidity, particularly in the summer months, can wreak havoc on both interior and exterior painted surfaces. In Kansas City, where July and August often bring average humidity levels above 70%, moisture can seep into walls and beneath paint layers. This causes common issues like:

• Paint blistering in humid weather: Bubbles form when trapped moisture expands under the paint.

• Peeling: Adhesion breaks down when water infiltrates poorly prepared or aging surfaces.

• Mold and mildew: Especially in kitchens, bathrooms, and shaded exteriors, persistent moisture leads to unsightly, potentially hazardous fungal growth.

Why Kansas City Summers Are Tough on Paint

Kansas City experiences not only high humidity but also dramatic temperature swings. Surfaces expand and contract with heat changes, which can cause cracking and further expose paint to moisture. Understanding these Kansas City humidity effects on paint is the first step toward proper maintenance.

Top Maintenance Tips to Protect Your Painted Surfaces

Regular Inspections and Early Repairs

Routine visual checks are key to maintaining painted surfaces in humidity. Look for:

• Cracks or flaking

• Discoloration

• Bubbles forming beneath the paint

Touching up minor damage prevents larger problems. Contact Pileggi Painting Kansas for a seasonal inspection if you’re unsure.

Cleaning and Mold Prevention Best Practices

Use a gentle solution of mild soap and water to wipe down surfaces monthly. Pay special attention to:

• Bathroom and kitchen walls

• Shaded exterior areas

Preventing mildew on painted walls starts with regular upkeep and proper ventilation.

Protecting Indoor Spaces with Dehumidifiers and Fans

In high-moisture areas, especially during summer:

• Run exhaust fans during and after showers or cooking

• Use portable or whole-home dehumidifiers

This keeps moisture out of your paint and prolongs its life.
