Coverage
In practice, the quantity of Zinga required to coat a given area is dictated by both the required dry film thickness (DFT) and the depth of the blast-profile.
As a guide to coat 1m2 of steel with a Blast profile of 60micons Rz, at a DFT of 60microns (with no wastage) will require 0.41kg of Zinga.
Or coverage equates to 2.41sqm per 1kg of Zinga.
