The challenge
The metal sheeting of the circular clinker storage was covered in encrusted clinker dust, with rust and blistered paint underneath. Left untreated, corrosion would thin the sheets and threaten the building envelope.
The sheets had to be cleaned back to sound metal before any new coating could be applied.
Scope of works
- Removal of encrusted clinker deposits from the cladding
- High-pressure hydroblasting to strip loose paint and rust
- Epoxy anti-corrosion primer applied immediately to avoid flash rust
- UV-resistant polyurethane topcoat, with dry film thickness checks
Outcome
The cladding is fully restored and protected, extending the life of the building. Large-area painting at height is often done by rope access. See also the clinker storage roof inspection.
