The paste should be pre-soaked in a paste: solvent ratio of between 1:1 to 1:3. Pre-soaking generally takes from one to eight hours. In general finer grades require longer pre-soaking duration compared to coarser grades. If using solvent alone is not feasible, the liquid coating medium can be substituted, but the dispersion time may be extended. Use low shear, slow speed mixing to achieve a smooth consistency mixture till it is free from aggregates. High shear dispersion technique should not be used as this will destroy or distort the aluminum pigment flakes affecting the overall intended aesthetic effect.
