Paint Problems

 

Blistering

blistering

Blistering: Dome shaped paint bubbles indicating loss of adhesion. Can occur in isolation or groups.

Blistering probable causes: Trapped moisture trying to escape through the paint, painting at temperatures above 90°F. Using oil paints on wet/damp surfaces. High humidity such as rain or heavy mildew before the paint dries. Painting a warm surface in direct sunlight, or application over heavy chalk.

Blistering solution: Find and remove the sources of moisture. Control moisture with adequate venting, stopping leaks and acrylic caulking. Remove all of the blistered areas and other loose paint by scraping and sanding. Power washing recommended for large areas.

Primers & exterior finishes: Priming is essential for better adhesion, sheen uniformity, mildew control and durability. Select a top quality exterior paint in the color and sheen of your choice.
