There is no Florida statute, code rule or manufacturer calendar that says every stucco house must be repainted after a fixed number of years. Condition is the better trigger. Sun exposure, color, coating quality, preparation, salt, mildew, moisture and wall orientation can make different sides of the same house age at different rates.
Watch the Paint, Not Just the Calendar
- Chalking: powder transfers to a hand or cloth.
- Fading: sun-exposed walls no longer match protected areas.
- Peeling or blistering: diagnose adhesion or moisture before repainting.
- Mildew: clean and correct moisture/sprinkler conditions; repainting may not be necessary if the film is sound.
- Cracking or failed sealant: determine whether it is a coating, sealant, stucco or water-management problem.
Why Florida Houses Age Unevenly
UV exposure, heat, wetting and drying, shade and biological growth vary around a building. A west-facing wall can weather differently from a protected lanai wall. Coastal salt and irrigation overspray can create additional localized maintenance.
Do Not Repaint Over a Failure Mechanism
If a coating is peeling because the wall stays wet, simply repainting restarts the failure clock. Sherwin-Williams’ maintenance guidance treats mildew, efflorescence and moisture-related coating defects as conditions to correct before applying a new finish.
Surface Blueprint Rule
Use age as a prompt to inspect, not as proof that paint has failed. Repaint when the coating system and substrate condition justify it, and document the exact products used so the next maintenance decision is easier.
