Cladding spraying is the better option when panels are structurally sound but cosmetically worn or showing surface corrosion. It costs less, finishes faster and avoids downtime. Replacement is better when sheets are perforated, leaking or failing structurally, where a coating cannot restore performance.
When Does Spraying Win?
Spraying wins on cost, speed and disruption. The building stays in use, there is no stripping or disposal, and the work finishes in days. For weathered plastisol, faded colour and early cut-edge corrosion on solid panels, recoating delivers a like-new envelope without the price of re-sheeting.
| Factor | Cladding spraying | Full replacement |
|---|---|---|
| Relative cost | Low (often a third or less) | High |
| Disruption | Minimal, stays operational | Significant downtime |
| Timescale | Days | Weeks |
| Best for | Sound but weathered panels | Perforated or failing panels |
When Is Replacement the Right Call?
Replacement is unavoidable once steel is perforated, panels leak, or insulation behind composite cladding is saturated. A coating seals surfaces, it does not rebuild failed sheets. If a survey finds widespread perforation, re-sheeting is the honest answer and we will say so.
How Do the Costs Compare?
The gap is large. Recoating typically runs at a fraction of replacement, so most owners price it first. The full numbers, including access and condition factors, sit in our guide to the cost of respraying cladding, which shows where each route lands per square metre.
Will a Respray Last Long Enough?
A correctly specified respray protects for well over a decade, which is enough to justify it on most sound buildings. Check realistic timeframes in our guide to the expected life of a cladding respray before committing to costly replacement.
Not Sure Which You Need?
