Review: Excellent brown pigment - Product came packaged in bag in a foil bag. No instructions but I figured it out with some Google help. It worked perfectly (turning white thinset into a nice dark brown). Will buy again when it's time for more repairs (this is setting stone into a waterfall + pond). One five pound bag of pigment was plenty/enough for a 50 lb bag of fortified thin set. Be careful, this stuff will dye anything it touches (clothes, gloves, tools, concrete floor, stone).
Review: Well made - Straight up flat real brown coloring. Does not come out looking bronze. Easy to mix into resin and gives an opaque matte brown coloring.

### ⭐⭐⭐⭐⭐ A little goes a long way
*by A***Y on April 22, 2026*

Okay there’s a little bit of a learning curve, so start with a small amount adding into your white grout. It’s very messy so be prepared or you’ll be wearing it and washing it off your piece forever …like me 🤭
