Rock N Soil Matte Gray Iron Oxide Pigment Powder, Concrete dye, Grout Colorant, Color Dye for Cement Epoxy - 5 Oz, Grey

When I first mixed a whole bag with a 7lb box of feather finish I was MAD--I thought it was not pigmented at all. Turned out I just needed to add water to the mix... and then it was way pitch black. So, I guess the point is that it's super pigmented and I recommend playing with your ratios to get the shade you want. I found half a bag mixed with one 7lb Henry's box was the perfect shade for my fireplace makeover.

I like this product, as it's the real deal. Sucks a magnet right to it real fast & strong, and that's how you know it's authentic. Very pleased with this product. Thank you!

This works well. It is not necessarily what most use it for but for me this worked to make eyebrow shades because my brows barely show. When compared to conventional shades and the thought of buying for life, this is much more affordable. The colors look natural. When I am done, I will use it for soapmaking, so no loss at all! This last thing was why I didn’t feel bad about spending a little extra.

I used this to color the bottom part of a cement planter that I made in a mold. I really just made this quick planter just to try out this product. I mixed a few spoonful's of the powder into the dry cement and then added water and mixed. You can see in the picture that the bottom part of the pot is blue and I was happy that it didn't take that much pigment to get this shade. I did find though, that the pigment settled against the plastic mold and after unmolding it, when I lightly sanded the surface, a lot of pigment was sanded off. But this is priced well compared to similar products so I'm happy with it and will enjoy using it to make some better looking planters than the one in this picture.

We used this for our bathroom floor which we decided to do a black cement.And it looks really great.I was nervous that it wouldn’t be pigmented enough, but it really was pigmented.

Well we made some concrete pumpkins with this concrete color. They turned out awesome. Only thing I would suggest with this is that you clear coat the concrete after, it leaves your hands with an orange glow. But good stuff!

Used way more than i should have had to in just one bag of mortar mix and then it dried a grayish color…not even close to black.When purchased locally the pigment is very black and so is your mortar mix, using 1/2 cups.I used two cups of this powder to get gray. They’ve cut the pigment with something else. DO NOT BUY.

Works great. I used a lot to get rich color. Good color. Super!
