The lifetime of a coated steel sheet may be defined as the time it takes to reach the stage where re-coating is necessary to preserve its performance or aesthetics and can be predicted using manufacturers’ projected performance data. It can be seen when the coating starts to fade, craze and/or delaminate or, on smooth finish coatings, when it starts to blister and spot corrode.


The coating of profiled sheet roofs in order to extend the waterproofing life of such structures has long been within the realms of the liquid roof waterproofing industry.
