Matte Yellow Iron Oxide Powder, Concrete Pigment Powder, Grout Colorant, Color Dye for Cement Stucco Plaster Mortar Paint Coating Wood Stain Putty Epoxy Resin - 5 Oz, Yellow Ochre

At first, I thought the pigment was too light in color. However, after mixing it with wet grout, it darkened and turned out perfect for my project. It seems the more you use the darker it gets.

Used it for Halloween costume. Works well

Easy to use, comes out black not grayish

Worked well to keep my concrete white, even though the media was beige.

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).

great results with this colored powder

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 🤭

Straight up flat real brown coloring. Does not come out looking bronze. Easy to mix into resin and gives an opaque matte brown coloring.
