Cut edge corrosion repair and lap sealing in Mottingham
Edges stabilised, sealed and coated for long-term protection.

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.

Recent project in Mottingham: Retail Pod — Reseal & Coat — delam removal; prime & seal; night works. Outcome: sound base; clean topcoat.

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

Applying primers, sealants and protective coatings in Mottingham
Specified seal widths and topcoat returns for durability.
  1. Assessment: Identify delamination, corrosion spots and moisture routes; plan access and safety.
  2. Prep & Edge Stabilisation: Mechanically remove failed coating; treat rust; degrease to a sound edge.
  3. Priming: Apply compatible metal primer to prepared areas for adhesion and protection.
  4. Lap Sealing: Tool elastomeric sealant into side/end laps, fixings and penetrations to specified depth/width.
  5. 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.

Cut Edge Corrosion — FAQs

Where factory coating ends at a cut edge or lap, UV and weathering lift the finish. Exposed steel then oxidises and moisture tracks into joints, accelerating corrosion.

We plan phased access and can work nights or weekends. Most clients remain fully operational during works.

Pricing reflects extent of delamination, access, exposure and specification. We provide fixed quotes after survey or photo review.
