Cut Edge Corrosion Treatment Loughton

Cut edge corrosion develops where factory coatings terminate at cut edges, laps or fixings. Once coating lifts, steel oxidises and moisture tracks into joints. We stop the process, seal the paths and protect the edge with durable coatings.
Common Warning Signs
- Feathered or lifting coatings at edges and lap lines
- Rust streaks below joints or around bolt heads
- Pinholes, small gaps or damp insulation under laps
- Water ingress during wind-driven rain events
Our Method

- Assessment: Identify delamination, corrosion spots and moisture routes; plan access and safety.
- Prep & Edge Stabilisation: Mechanically remove failed coating; treat rust; degrease to a sound edge.
- Priming: Apply compatible metal primer to prepared areas for adhesion and protection.
- Lap Sealing: Tool elastomeric sealant into side/end laps, fixings and penetrations to specified depth/width.
- Protective Coatings: Install UV-stable topcoats with returns beyond lap edges (typically ≥50 mm); QA and clean-down.
If advanced section loss is present, selective sheet replacement may be advised after survey.
