A variety of colors and finishes can be incorporated into the FMG face mix. UV stable liquid or dry powder pigments can be added to FMG to provide a vast range of colors. Aggregates can be added to the face mix to achieve desired texture effects when sandblasted and sealed. Metal powders can also be added to the face mix to achieve various cold cast metal effects. After demolding, the cold cast metal can be patinaed or polished to achieve a desired finish in a fraction of the time and cost normally associated with foundry cast metal.
