MARBLERS Liquid Colorant 11oz (310g) [Jet Black] | Water-Based | Highly Concentrated | Tint, Pigment | Odorless | Non-Toxic | Concrete, Cement, Mortar, Grout, Gypsum, Water-Based Paint, Plaster

I bought this to darken a 5 gallon bucket of white paint to a nice gray. I was amazed at just how dark of a grey it made! It comes as a bottle of thin ink, no leaks. This stuff is easy to use, and a great value for your money when compared to a lot of the more expensive alternatives!

Thanks for showing an accurate color on your website/online! I tried three separate grouts to accomplish what minimal amounts of this bottle was able to. It is my second purchase, also have the camel and it has worked well too! Best brand so far - I always mix it with the water to ensure there are no shooting stars in my microcement. Easy to use bottle, good quality, accurate color shown, and great value for how much product is needed Ignore the areas that are covered with trim.

I tried at least 15 different dyes, colorants, oxides, powders and liquids because my client wanted bright flag red concrete for her patio table. This is the only red colorant in existence that makes concrete red. I tried for months! Use white cement or mortar with Marblers and the color is vibrant. It is highly pigmented, I used 1/2 cup. This is the only colorant I will ever purchase again. Red is hard ya'll!

Worked great for staining concrete planters!

Nice and concentrated but has too much green

Absolute trash, I mixed 3x the recommended amount and my paint still came out lavender, please for the love of God and everything holy buy anything else, I'm honestly going to request a refund because of how garbage this product is. DO NOT BUY!!!

I used the fir green dye to color some water based concrete sealant. It was very vivid and very green after diluting it to get my preferred shade.. i painted two coats ofmy sealant mix on some cast concrete blocks I made for a project. I left the sealed concrete castings out in the sun for a few days while on a trip, and came back to my lovely green having turned blue. The yellow colorant bleached out in the sun. This was unexpected and a bit disappointing.

This was the best addition for our Halloween display. Enjoy the photo. Illuminated with our black light amazingly. Holds the color for days.
