Matte Ultramarine Blue Oxide Pigment Powder - 5oz/142g - Concrete Pigment, Cement Color Pigment, Resin Epoxy Dye, Colorant for Gypsum, Plaster, Putty, Grout, Lime-Wash, Milk Paints

It is great to be able to change grout color with this pigment!

I mixed this with cement tile sealer to restore color to damaged cement tiles and it worked beautifully. The powder is so fine that it mixes instantly without clumping. The color shown is a true representation of the color in person.

I used it to mix with white grout on a mosaic piece and it worked great.

Worked well pretty color

Matte Ultramarine Blue Oxide Pigment Powder - 142g/5oz - Concrete Pigment, Cement Color Pigment, Resin Epoxy Dye, Colorant for Gypsum, Plaster, Putty, Grout, Lime, Milk Paints First impressions: Nice bag of powdered colorant for epoxy or clay. The pigment is ground very fine and is ready to use. Installation/setup: Mix with epoxy or clay and the like to add a blue color. Final thoughts: I got this to mix with my buff colored pottery clay to add a small amount of blue to swirl in my mugs and vases. The color did work, I used a little under 10 percent by weight to a small amount to marble in my clay. The method I used didn’t work very well, I think I need more practice. It turned out a bit muddy. I may try a whiter clay body to start with so I can get a cleaner blue. I think I’ll use the rest in my epoxy work, coloring the clear epoxy will do this powder more justice, it’s such a pretty blue. I like this and I’m glad I got it. ⭐️1 star - I don't recommend it at all, poor quality. ⭐️⭐️ 2 stars - I don't recommend it, it has multiple faults, or a very high price. ⭐️⭐️⭐️ 3 stars - It's passable, It has some faults but the quality is ok for what it is. ⭐️⭐️⭐️⭐️ 4 stars - Product quite acceptable, it does what it promises. ⭐️⭐️⭐️⭐️⭐️ 5 stars - Product that I totally recommend.

Used this to stain concrete, great results

Not the most pigmented. I used this to color plaster off Paris but it came out a very light pink not very vibrant

Beautiful
