Matte Gray Iron Oxide Pigment Powder, Concrete Pigment, Grout Dye, Color Dye for Cement Epoxy Stucco Plaster Mortar Paint Coating- 5 Oz, Grey

GOOD for showing a "making tempera" demo. Not as pure pigment as from a paint type dealer, but excellent for my demo because of the price.

It looks like I wanted. I added it to charcoal grout to make it more black. It was messy but I expected that. Reasonably priced.

We spent $750 on real flagstone in our back yard project but needed another $650-$700 in additional flagstone to complete our walkway. We decided to make our own flagstone using vertical blinds as forms that we shaped, bagged concrete and this incredible dye to turn the concrete black by spreading about 2 -3 tablespoons of dye to the top of the freshly poured concrete. Total cost was about $100 in concrete, $20 for the vertical blinds and the coat of the dye. Get creative and save a ton of money by making your own flagstone pavers. The dye comes in various colors.

This powder mixes in easy and looks good but it wasn't as bright as I was hoping.

Product mixes well. Color runs true through out the project

Perfect color match to make my mortor blend in with the rock

We use this to build our pizza ovens. Looks great! Easy to mix. Great price!

The product looked terrific, but we didn’t have to use it after all. The contractor had a company make our fireplace mantle, and they already had the dye to use into the mantle when it was made.
