Ultimately, the degradation of appearance may reach a stage at which it is no longer acceptable. This is not the end of the functional life of the sheet.
Over-paint solutions are available for pre-finished steel roof and wall cladding which can restore their appearance and significantly extend the building life.
When to repaint will depend on the location and circumstances of the building and its owners.
In a purely functional situation there is no requirement to over-paint a Confidex® guaranteed Colorcoat HPS200 Ultra® or Colorcoat Prisma® building during the guarantee period.
Suitable over-painting maintenance at regular intervals thereafter can extend the life indefinitely. It is important to choose the timing of the over-paint carefully to ensure the existing coating is still intact and does not require removal.
With suitable and timely maintenance, Colorcoat® pre-finished steel products can be expected to give a useful service life in excess of 60 years.
