Insulated metal roof and wall panels feature functionality, durability, and aesthetics to stand the test of time, but safeguarding your investment requires maintenance.
Effective cleaning and care will ensure the longevity and appeal of insulated metal panels (IMPs) – with even a splash of plain water able to rejuvenate metal roof and wall panels that must battle the elements daily.
“All painted buildings chalk and retain dirt to some degree. Mildew builds up, especially in damp areas,” says U.S. Steel. “Often, the only thing the building needs is cleaning. Removal of the dirt restores much of the building’s brightness and original color. Rust problems can be unsightly but may only need cleaning or minor repair while cleaning.”
Insulated roof and wall panels are manufactured with interior and exterior finishes that include high-performance coatings such as fluoropolymer, silicone polyester, and polyester.
The good news is that the molecules on the surface of these high-performance coatings are so tightly bound together that it makes them resistant to many elements found in the environment such as air pollution, acid rain, and general airborne dirt.
While these IMP coatings are robust, periodic cleanings can address the accumulation of resins and other residues and will extend the life of these finishes.
From the day buildings are constructed, they fight the elements in a 24/7 battle to age gracefully.
Insulated metal roof and wall panels not only have to combat the relentlessness forces of wind, water, UV rays, and temperature fluctuations but are also susceptible to a range of contaminants. These include:
Drinking plenty of water is a simple life hack to help humans to a longer lifespan, and water works wonders for caring for metal buildings as well.
Starting with a straightforward approach, coating expert Valspar suggests employing plain water via hoses or pressure spray equipment to dislodge surface deposits on metal roof and wall panels.
Water should be applied to your building at least once a year to clean it but may need washing up to three times annually in certain areas with environmental hazards.
Two key points to remember before initiating the cleaning process with water or other substances are:
While water is a great starting point, for persistent residues, more potent methods become necessary.
The cleaning options for your metal building beyond plain water include two groups:
o Alcohol such as ethanol (denatured alcohol) and rubbing alcohol (isopropyl alcohol).
o Petroleum Solvents and Turpentine (VM&P naphtha, mineral spirits, kerosene, turpentine).
o Aromatic Chlorinated Solvents (Xylol, Toluol)
o Ketones, Esters, Lacquer Thinner, and Paint Remover.
Always remember that most organic solvents are flammable and/or toxic and must be handled with care.
Cleaning solvents should be kept away from sparks, electric motors, and open flames, and always use adequate ventilation, and protective gear such as goggles.
You should avoid using harsh chemicals when cleaning steel buildings, as they can damage the surface finish. You should also check with the manufacturer before using any substances to ensure you do not void the warranty.
Mildew, rust, and graffiti are three of the special concerns that building owners must confront when cleaning their steel walls and roofs. Here is how to tackle all three:
When it comes to the care and cleaning of your metal building, try these 20 best practices:
1. Regular Inspection: Conduct routine inspections of your metal building to identify any signs of dirt buildup, rust, paint chipping, or other potential issues.
2. Scheduled Cleaning: Set a regular cleaning schedule based on the environment and level of exposure. This could be quarterly, semi-annually, or annually, depending on your building's location and conditions.
3. Start with Water: Begin your cleaning process with plain water using hoses or pressure spray equipment. This often removes superficial dirt and debris effectively.
4. Use Soft Brushes or Cloths: For stubborn grime, use soft brushes or cloths to gently scrub the surface. Avoid abrasive tools that can damage the coatings.
5. Select Mild Detergents: If water alone is insufficient, opt for mild, non-abrasive detergents. Test the detergent in a small, inconspicuous area first to ensure compatibility with the coatings.
6. Solvent Safety: If using solvents, carefully follow manufacturer instructions and safety guidelines. Ensure proper ventilation, wear protective gear, and keep away from open flames or sparks.
7. Target Contaminants: Tailor your cleaning approach to the type of contaminant. Use appropriate solvents for removing graffiti, specialized solutions for mildew, and diluted acids for rust stains.
8. Gentle Pressure: When using pressure spray equipment, avoid excessive pressure that could damage coatings or push water into crevices. Use a moderate pressure setting.
9. Rinse Thoroughly: After cleaning, always rinse the surfaces thoroughly with clean water. Residual cleaning agents or chemicals could lead to deterioration if not washed off properly.
10. Avoid Standing Water: Prevent water from pooling or standing on metal surfaces, as it can lead to premature corrosion. Ensure proper drainage to redirect water away from the building.
11. Minimize Abrasion: During cleaning, avoid aggressive scrubbing or abrasive materials that can scratch or wear down the coatings.
12. Mind Weather Conditions: Choose a calm, dry day for cleaning. Windy conditions can spread cleaning agents, and rain shortly after cleaning might affect the results.
13. Document Cleaning: Keep records of your cleaning efforts, including dates, methods, and any challenges you encounter. This documentation can help refine your cleaning approach over time.
14. Safety First: Prioritize safety for yourself and those involved in the cleaning process. Use appropriate protective equipment and follow all safety guidelines.
15. Consult Manufacturer Guidelines: Refer to the manufacturer's recommendations for cleaning and maintenance, as they are tailored to the specific coatings and materials used in your metal building.
16. Professional Assistance: For complex cleaning tasks or in case of extreme contamination, consider consulting professionals who specialize in metal building maintenance.
17. Preventive Measures: Implement measures to prevent contaminants in the first place, such as regular landscaping to prevent organic growth, and addressing sources of rust, like steel debris.
18. Touch-Up Painting: If you notice chipped or peeling paint during cleaning, address it promptly with touch-up painting to prevent further deterioration.
19. Educate Staff: If your building is maintained by a team, ensure that everyone involved understands the proper cleaning techniques and safety protocols.
20. Continuous Monitoring: Keep an eye on the condition of your building even after cleaning. Regular monitoring allows you to catch issues early and take corrective action.
