Yes. As a preventative maintenance measure, HouseSensationsArt recommends applying a quality exterior-grade clear coat or automotive clear protective coating every 1–2 years in normal outdoor environments.
Signs installed in coastal, saltwater, or brackish water environments should be inspected more frequently and may require more frequent clear coat applications due to increased exposure to moisture, salt, and corrosive conditions.
If the powder-coated finish becomes chipped, scratched, or otherwise damaged, repairs should be completed and a clear protective coating applied immediately to help prevent moisture intrusion and corrosion.
Inspect your sign at least twice per year for:
Addressing minor issues early can significantly extend the life of your sign.
Minor scratches should be repaired as soon as possible to prevent moisture from reaching the metal.
Surface rust can usually be repaired if addressed early.
Sand the affected area until all visible rust is removed.
For heavier rust, use a wire brush or rust-removal product as needed.
Remove all sanding dust and debris.
Allow the area to dry completely.
Apply a rust-inhibiting metal primer.
Allow the primer to cure according to the manufacturer's instructions.
Apply a matching exterior-grade paint.
Multiple light coats generally provide the best finish.

Professional refinishing or replacement may be the most practical solution depending on the extent of the damage. Severely damaged signs should be inspected and repaired promptly to prevent further deterioration and maintain structural integrity.
Custom Steel signs installed outdoors are exposed to sunlight, rain, humidity, snow, ice, salt air, lawn chemicals, fertilizers, airborne contaminants, and other environmental conditions. Routine cleaning and preventive maintenance are the owner's responsibility and are essential to maximizing the product's lifespan and appearance.
For most outdoor installations, HouseSensationsArt recommends routine cleaning and the application of a protective clear coat every 1–2 years. Signs located in coastal, saltwater, or brackish water environments may require more frequent inspections, cleaning, and clear coat applications.
Never pressure wash your sign or use bleach-based cleaning products. Only use mild dish soap, water, or automotive-approved cleaners that are safe for painted and clear-coated surfaces.
Failure to maintain protective coatings or promptly repair damaged finishes may result in premature finish deterioration, corrosion, or weather-related wear that is not covered under warranty.
Proper care will help maximize the appearance and lifespan of your UV printed ACM (Aluminum Composite Material) sign.
Rinse thoroughly with clean water after washing.
Dry with a clean microfiber cloth to prevent water spotting.
Apply a high-quality exterior automotive-grade clear coat every 1–2 years as preventative maintenance in normal outdoor environments.
In coastal, brackish water, or high UV exposure areas, inspect annually and reapply as needed.
If the factory clear coat becomes scratched, worn, or damaged, apply a new clear coat immediately to help protect the UV printed surface.
Periodically inspect your sign for:
Address any damage promptly to prevent moisture intrusion and extend sign life.
These products can damage the UV print, clear coat, and protective finishes.
After storms, hail, or high-wind events:
With proper maintenance, quality ACM signs featuring UV printing and a protective clear coat can provide 7–10+ years of outdoor service, with many installations lasting considerably longer depending on climate, sun exposure, and maintenance practices.
