Protective roof coatings and corrosion control

Treat the rust before applying the finish

A coating cannot rescue a poorly prepared surface. We assess corrosion, previous paint layers, adhesion and roof condition before specifying preparation, treatment, primer and protective finish.

01

Substrate assessment

Determine what is beneath the visible peeling, chalking or rust before selecting a system.

02

Preparation matters

Cleaning, removal of failure and corrosion treatment are matched to the roof condition.

03

Airless application

Professional application for commercial and industrial roof areas where suitable.

Defined roofing scope

A coating system—not a coat of paint

Compatibility and preparation are critical. The scope must deal with existing failure before a new protective layer is applied.

Practical roof advice

When coating is appropriate—and when it is not

Coatings can protect serviceable metal roofing and improve appearance, but they cannot replace failed sheets, correct structural movement or solve every leak.

Peeling often indicates poor adhesion, contamination, incompatible layers or inadequate previous preparation. Covering it simply transfers the failure into the new system.

Severely corroded or perforated sheets should be replaced. We separate repair and replacement items from coating work so the scope is clear.

Useful answers

Before the inspection.

Can you coat over rust?

Not without suitable preparation and treatment. The extent of corrosion determines whether treatment is possible or sheet replacement is required.

Will a roof coating stop every leak?

No. Failed flashings, fasteners, penetrations, drainage or structural movement must be repaired separately.

Why is the existing paint peeling?

Common causes include poor cleaning, weak underlying layers, incompatible products, moisture, corrosion and inadequate surface preparation.
