I couldn't really get a true black out of this pigment or close to black. The best I was able to achieve was a charcoal color, which isn't a big problem because charcoal is one of the more popular colors in the items that I sell. Still a good product at a good price, but definitely not black, even when you oversaturate your mixture with pigment. It definitely helps tone down the yellow hue of CementAll, even if you use this pigment to achieve a gray shade.I'm going to try the Supra Black next time and hopefully it will get me a shade closer to black, which I need for some of my trays.

I’m just in LOVE with this Supra black pigment!! It’s the best, truest black I’ve seen on the concrete pigment market! But be careful because it is very messy and you have to do a lot of cleaning up but it is totally worth it to create a pure black product.The other ‘black’ pigments I’ve used are really just a charcoal color and never quite reaches that deep pure black color. So glad I found Globmarble! I’ll definitely check out their other pigments!

Color is GREAT! However, there is a lot of waste due to the packaging. It arrived in a taped up zip lock bag. I could already see the powder leaked out in the bag as pictured. However, to get the bag open due to all the tape I had to use a knife. This was a VERY MESSY process. I gave the product 4 stars due to the color being exactly what I wanted.But, the mess is almost worth forsaking the quality for another cheaper brand I have been using that has much much better packaging with zero mess!

If you are looking to add color to a stamped concrete patio, this stuff is great! One bag did the trick for us. I watched a how to video on YT to see how to apply to a stamped concrete patio that had faded and not been sealed in several years. Mix the powder with water in a watering can to the color pigment you want and then "water" it on the concrete while spreading it out with a broom. How much color you want to apply is up to you. You can get multiple colors and do a mix if you want. Once the color is how you like it, let it completely dry and put the concrete sealer in top. It was kind of a messy job, but it come out great!

This is the only pigment that i was able to tint diamond veneer plaster with true lamp black without affecting the strength and consistency (I’ve tried a hunch of universal colorants - they don’t work for diamond veneer) . Oxides work but they have ugly brown undertone. This is true charcoal deep black - as good as it gets.

Used with cementall- definitely the best black pigment to get a true black and you don’t need much to achieve a deep black pigment. Very happy. Will continue to buy

This is the best black concrete pigment ever! All of the others just turn cement a dark gray but this is the truest black

This is a great way to add a nice bright white to a stepping stone, easy to add and stir into the cement mix. Really makes your add-ons (such as stones or beads) stand out.
