Buddy Rhodes Pure Collection Powdered Pigments can add vibrant color effects to duoMatrix NEO polymer-modified gypsum. When adding color, the mix ratio is 100A:70B parts by weight plus 1-5% pigment. Dry components are sifted and mechanically mixed into the liquid Part B component. For best results, the silicone mold is filled partway then slushed to coat the entire surface before backfilling with the remaining mixture.
