Cut edge corrosion treatment project in Llanelli
Edges and laps stabilised, sealed and protected.

Cut edge corrosion typically begins at sheet cut edges, side/end laps and around fixings where factory coating stops. UV and weathering lift the finish, exposing steel and allowing moisture to track into laps. If ignored, it progresses to leaks, staining and premature sheet replacement.

Recent project in Llanelli: Showroom Roof Upgrade — side laps; bolt heads; trims; phased access. Outcome: tidy seals; colour-accurate finish.

Early Indicators to Watch

  • Lifting or feathered coatings at lap edges
  • Rust staining beneath laps or down elevations
  • Pinholes and hairline gaps along side laps
  • Occasional water ingress during wind-driven rain

How We Treat Cut Edge Corrosion

Lap sealing and protective coating in Llanelli
Specified seal widths and topcoat returns for durability.
  1. Survey & Adhesion Check: Identify delamination, rust spots and moisture routes; test substrate soundness.
  2. Mechanical Prep & Arrest: Remove failed Plastisol/paint; treat corrosion and degrease to a sound edge.
  3. Prime: Apply compatible metal primer to stabilise edges and prepared areas.
  4. Seal Laps & Fixings: Tool sealant into side/end laps, penetrations and bolt heads to specified depth/width.
  5. Protective Topcoats: Install high-performance coatings with returns beyond the lap (typically ≥50 mm) and complete QA/clean-down.

Where steel loss is advanced, selective sheet replacement may be recommended after survey.
