Guaranteed against significant shift of gloss retention and colourfastness for installations not within 10km of the coast, tidal estuary or any potential industrial or external pollutant.

^{All mitres, cut edges and drilled holes must be sealed with a suitable low modulus neutral cure silicone to ensure no bare metal edges are open to the environment, the responsibility for this is the fabricator and installers. Any on site damage to the coated material resulting in a breakage to the film should be repaired within 24 hours. During installation the responsibility for this lies with the installer, after installation this is the homeowner’s responsibility. Our Powder Coating guarantee excludes ‘Hazardous Environments’ as defined by ISO 12944-2-2018, which include marine environments affected by salt laden atmospheres, areas of industrial pollution and areas enclosing, or in close proximity to a swimming or leisure pool. Where Sheerline products are to be installed within 10km of such a Hazardous Environment then the approved Sheerline fabricator must request a specific ‘Marine Grade’ powder coating – which may be covered by a different guarantee and cleaning regime, see point 2 below.}

Bespoke guarantees against significant shift of gloss retention and colourfastness can be provided by our suppliers based on specific locations, or colours that fall outside our standard cover as detailed in point 1. The final guarantee is defined by a free, pre-order enquiry service and is based on the installation address. Options for higher performance surface finishes can then be discussed if required to meet specific project requirements. Surcharges may apply.

^{For areas less than 50 metres from the high-water level of a marine environment, or less than 2m from the edge of a swimming/leisure pool, then no guarantee will be offered.}
