Exterior paint is a protective coating only when the surface below it is sound enough to hold the finish. Peeling paint, chalking, sun exposure and weathering can be ordinary maintenance, while rot, active water entry or unstable siding needs repair before another coat is applied.
Exterior Surfaces
Projects may include compatible painted trim, wood siding, selected masonry or stucco coatings, exterior doors and other prepared surfaces.
Roofing, decks requiring specialty finishes, metal requiring industrial coatings, and large specialty surfaces should be scoped separately.
Surface Preparation
Preparation can include washing appropriate surfaces, scraping loose paint, sanding sound edges, spot priming and protecting nearby windows, roofs, hardscape and plants.
The amount of preparation depends on the existing coating and substrate.
Painting over loose, wet or deteriorated material usually shortens the life of the new finish.
Repairs Before Painting
Small finish defects can be addressed as preparation, but rot, failed siding, deep stucco cracks, open joints caused by movement, active leaks or structural deterioration need their own repair.
If caulk is required at compatible joints, the sealant should be appropriate for the exterior material and coating system.
Paint and Finish Selection
Exterior products differ in sheen, flexibility, adhesion and exposure rating.
A new coating should be compatible with the substrate and what remains of the previous finish. Dark color changes, heat exposure and strong sun can affect appearance and performance.
Weather and Application
Temperature, wind, direct sun, moisture and rain risk all influence exterior painting.
The surface needs enough dry time before and after application according to the paint manufacturer.
FAQ
Can peeling paint simply be painted over?
No. Loose coating and the reason for failure should be addressed during preparation.
Does exterior painting include rot repair?
No major rot repair should be assumed.
Can stucco be painted?
Potentially, after the stucco condition, existing coating and any cracks or moisture issues are reviewed.
Can the exact old color be matched?
A close match may be possible, but fading and weathering can make an exact match difficult.
