Ppg paint — Louisville/Jefferson County, KY

Signs that your Louisville home needs exterior painting include visible peeling, chipping, or cracking paint, especially on areas exposed to direct sun. You might also notice chalking, where a powdery residue appears when you rub the surface, or the presence of mold and mildew. If the paint appears significantly faded or if you see evidence of wood rot or moisture damage beneath the paint, it's time to consider a repaint. Regular inspection is key.

Louisville's humidity levels can impact exterior paint by potentially promoting mold and mildew growth if the paint is not properly formulated. High moisture content in the air also affects drying times. We recommend using high-quality acrylic latex paints that contain mildewcides and offer good breathability, allowing trapped moisture to escape. Proper surface preparation, including thorough cleaning, is also crucial to prevent moisture-related issues.

For wood siding in Louisville, preparation typically involves thorough cleaning, often with a pressure washer, to remove dirt, mildew, and chalking paint. Loose or peeling paint is meticulously scraped away, and the surface is sanded smooth. Any damaged or rotted wood sections are repaired or replaced. A high-quality primer specifically designed for wood is then applied to seal the surface and ensure optimal adhesion for the topcoats, protecting against moisture and UV rays.

Louisville experiences significant temperature fluctuations throughout the year, which can affect exterior paint. Extreme heat can cause paint to expand, while cold causes it to contract. If the paint is not flexible enough, these changes can lead to cracking or peeling. High-quality acrylic latex paints offer the flexibility needed to withstand these cycles, maintaining their integrity and adhesion over time. Proper application during suitable temperatures is also critical.
