How can it be used?

...

MIRACLE provides comparable protection to conventional galvanising without the need for topcoats. Although MIRACLE is only available in grey (the natural colour of zinc), the significant advantage of this form of application is that the MIRACLE layer can be re-coated at any point in the future with the bare minimum of preparation and without compromising the integrity of the coating (see Re-charging of MIRACLE). MIRACLE on its own is often used, because the structure is already on site or too big for the molten zinc baths. Additionally MIRACLE is commonly specified on delicate structures (wrought iron gates, sculptures) or when architectural demands require a higher standard of surface finish (no need to drill to de-gas, fettle).

For optimal protection, MIRACLE should be applied in two layers of 60 or 90 µm DFT each.

...

MIRACLE and the topcoats work in harmony to extend the lifetime of the system. As the MIRACLE layer will not begin to sacrifice itself until the topcoat is breached, the original zinc thickness is maintained whilst affording the topcoat protection from under-creep and blistering.

In a duplex and triplex system (Active + Passive), MIRACLE should be applied in 1 layer of min. 60 to 80 µm DFT.
