Cut edge corrosion treatment project with lap sealing in Alperton
Edges stabilised, laps sealed and coatings returned beyond the joint for durability.

Cut edge corrosion starts when the factory finish stops — at cut edges, lap joints and around fixings. Once the coating lifts, steel oxidises and moisture tracks into the joint. We break that cycle with specification-driven prep, sealing and protective coatings.

Featured in Alperton: Retail Pod — Edge Reset — delam removal; prime & reseal; night works. Outcome: reliable base; clean topcoat.
