Maintenance Instructions Overview
This document provides maintenance instructions for products made of coated sheet metal and aluminium, such as cladding, roofing, rainwater systems, and façade cassettes. It emphasizes the importance of regular maintenance to extend both the aesthetic and technical lifetimes of these products.

Product Lifetime
Lindab distinguishes between aesthetic and technical lifetimes. The aesthetic lifetime refers to the period until the appearance no longer meets set standards, while the technical lifetime is the duration until the product can no longer protect the building's structure. Environmental factors like pollution, solar radiation, and proximity to saltwater significantly affect these lifetimes.

Environmental Impact
The environment plays a crucial role in the ageing of coatings. Polluted environments, solar exposure, and saltwater proximity accelerate the degradation of coatings. Regular cleaning is essential to remove dirt and impurities that can shorten the product's lifespan.

Damage and Inspection
Damage to the paint layer can lead to corrosion. Regular inspections are recommended to identify and repair any damage. Initial inspections should remove loose objects post-installation, and annual visual inspections should check for signs of wear like flaking or scratches.

Cleaning Guidelines
Rain often suffices for cleaning, but additional washing with a soft brush and water may be necessary, especially in polluted areas. Avoid strong solutions, organic solvents, and abrasive detergents. Rinse thoroughly to remove detergent residues.

Touching Up and Corrosion Treatment
Minor damages can be repaired with air-drying paint. For corrosion, remove rust and apply a zinc-rich undercoat followed by suitable paint. Edge corrosion requires sealing joints and applying a topcoat.

Repainting
Repainting should be done professionally with proven systems. Ensure surfaces are clean and dry, and avoid painting in direct sunlight or unsuitable temperatures. Follow paint supplier instructions for best results.

Best Practices
To maximize product lifespan, consider environmental factors when choosing materials, avoid standing water, ensure careful installation, and perform regular inspections and maintenance. Clean gutters and rinse areas not naturally cleaned by rainwater.
