Exterior House Painting: Prep That Actually Matters — cover image

A long-lasting exterior paint job is mostly preparation. Here is the prep that determines whether the finish lasts years or one season.

Clean and repair first

Paint fails fastest where the surface is dirty or damaged. Washing, scraping loose paint, and fixing rot give the new coat something to hold.

A painter who skips prep will be cheaper up front and more expensive in a couple of seasons.

Caulking and flashing

Gaps around windows, doors, and trim let water behind the paint. Good caulking is what keeps edges from peeling.

Ask how the crew handles flashing and problem joints before the color goes on.

Primer where it counts

Bare wood and repaired spots need primer to bond the topcoat. Not every wall needs it, but the repairs do.

Confirm the primer and paint system the crew plans to use so the layers are compatible.
