Peeling Windowsills & Frames

Water sitting on windowsills will eventually penetrate a paint film through cracks and openings in the coating.

Remedy:

• Remove all loose paint by scraping.
• Feather all rough edges with sandpaper.
• Remove old glazing and reglaze.
• Caulk joints at a 45-degree angle.
• Spot-prime with exterior primer.
• Use oil-based gloss paints for surfaces exposed to standing rain and snow.
• Leave a 1/16" edge of paint on the pane of the window to prevent water from getting behind the paint film.
• Use of storm windows helps prevent peeling from recurring.
