Cladding Paint Troubleshooting

Peeling is usually caused by poor adhesion to the substrate. Many cladding systems, such as plastisol or powder-coated panels, have smooth, non-porous surfaces that prevent coatings from bonding properly. Without correct preparation or priming, the coating will fail prematurely.

Not without preparation. Existing coatings must be thoroughly cleaned, degreased and mechanically keyed to provide adhesion. In many cases, an adhesion-promoting primer is required.

Yes, in most cases. Light abrasion helps create a surface profile that improves coating adhesion, particularly on glossy or factory-coated panels.

The coating will not bond correctly and is likely to peel, flake or delaminate, often within a short period after application.

For best results, yes. Primers are especially important on difficult substrates such as plastisol, powder-coated metal or previously coated surfaces.

Rust develops when moisture penetrates the coating and reaches exposed steel. This often occurs where coatings have been damaged, edges are exposed or preparation was insufficient.

Remove corrosion, prepare the surface and apply a suitable anti-corrosion primer or direct-to-metal system designed for external exposure.

Remove corrosion, prepare the surface and apply a suitable anti-corrosion primer or direct-to-metal system designed for external exposure.

Yes, particularly where bare metal is exposed or corrosion has been treated. Primers provide both adhesion and corrosion resistance.

Common causes include poor preparation, moisture ingress, damaged coatings and lack of proper corrosion protection.

UV exposure breaks down the surface of the coating over time, causing pigment loss and a chalky residue.

Yes, but the surface must first be thoroughly cleaned to remove all chalking. If left untreated, it will prevent proper adhesion of new coatings.

Yes. Prolonged UV exposure degrades coatings, leading to fading, brittleness and eventual failure.

After cleaning and preparation, applying a suitable coating system can restore colour and provide renewed protection.

High-quality coatings with UV resistance will significantly slow down fading, but all coatings will degrade over time.

Contamination such as dirt, grease or atmospheric pollutants can prevent coatings from bonding to the surface.

Surfaces should be washed with suitable cleaning agents to remove dirt, grease and contaminants, followed by rinsing and drying.

Pressure washing helps remove surface dirt but may not fully remove grease or embedded contaminants. Chemical cleaning is often required.

Poor cleaning will result in adhesion failure, leading to peeling or flaking of the coating.

Yes, particularly in industrial or urban environments where surfaces are exposed to oils and pollutants.

These areas are more exposed to moisture, movement and mechanical wear, making them more prone to coating breakdown.

They should be thoroughly cleaned, prepared and coated carefully to ensure full coverage and protection.

Yes. Poor sealing or coating failure at joints can allow water ingress, leading to corrosion and coating breakdown.

Yes. Screws and fasteners can corrode and should be properly prepared and coated as part of the system.

Ensure thorough preparation, adequate coating coverage and use of appropriate systems designed for external exposure.
