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

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.

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

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

This is drab, or olive at most. Even with a LOT of pigment, this would never be considered a grass color. and not nearly as bright/vibrant as the pictures. For pottery, though, this is just fine. We are mildly disappointed with the dull color, though.

Worked well pretty color

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

This pigment is such a pretty colour!!
