GlobMarble Red Iron Oxide Powder Concrete 1 lb Bag - High-Coverage Powder for Vibrant Color - Perfectly Suited for Concrete Color Pigment & Dye Applications

Great quality. You only need a little. Very pigmented

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 am only taking off one star because they did not add a warning label that you cannot inhale this stuff! Google what titanium dioxide does if inhaled. It causes lung cancer. However, it is also used in sunscreen, which it is fine to use on your skin. I used two bags of this dye per one bag of quickset mortar from Home Depot for my concrete countertops (pic attached). As with all concrete countertops you must grind the tops smooth. Luckily, after a few dozen minutes of sanding I thought to research if this dye was toxic and sure enough it is, when inhaled. Unfortunately I inadvertently inhaled some when first grinding. Also be aware that if you need more bags of dye the shipping time is not always the same. It varied for me from 2 days to about 8, delaying planned work.

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!

My repair came out amazing. I was able to match the color, perfect.

When added to my encaustic wax recipe, I found a cheaper alternative to the higher priced (great quality, however limited) competition. This was perfectly milled and easy to just blend into my other waxes, if needed. All by itself (including my encaustic wax recipe) I had no issues and found a brighter, thicker white than the ready made waxes out there. Im sure this will blend nicely into acrylic mediums, as well as oils. Great price, quick shipping, and im very happy. Will buy more and look forward to trying out their other colors they have available. Well done!

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!

Amazing rich colour in my soaps and concrete.
