I'm looking to make orange concrete, like Halloween or Harley Davidson. Has anyone else done this. I cannot source the color locally. I have been mixing white cement with mixtures of red, brown, white and black integral powder color from Increte. My hopes were not high in the first place, and now I know better.

Has anyone else done this and have a recipe? Or a starting point?

Hi Eller,

Use white cement, yellow and red pigment . The proportions of yellow and red you have to develop yourself. Pigments weight max 3% of cement weight
You know, when I asked my local source about orange pigment, one might think they'd have suggested that. Of coarse they are a large supplier and I am small potatoes.
But they did confirm they have yellow and red.
Thanks Brian.
It is also orange ready but how do you use yellow and red to set a shade. And the amount you add to the concrete will determine the intensity. If it is bright, add some black pigment

I don't get it....why not order the pigment that you need from trinic or buddy roads?

I made this little piece with water based stain

Buddyrhodes does not produce pigments, check with the manufacturer (will be cheaper):

Yeah sorry I still call it BR....actually you need to call Smooth-on now to order color for integral color....but Versa color from Trinic works awsome

I'm not sure what the major difference in pigments is, but I can buy enough pigment ( I think it's called 7 for 28) to color a yard of concrete for $22 ($44 and 2 yards if I buy yellow and red to make orange). Does anyone have experience or thoughts on how to pigments may differ?
If you want a bright orange you will need some intense pigments to go integral.

If you are just going one color then staining it would be the easiest thing to do. How you apply the stain will determine how even it looks.

I would recommend Trinic's Versa Color for this. You can choose any color and they will match it for you.

Almost three years ago I did a series of three sculptural benches that were two toned with the second color being a bright accent. Red, orange, and lime green. The pigments were liquid based and came from Blue Concrete. The dosage rates were about 10.5% which caused some issues with the chemistry. Also, the red and orange were full of air bubbles below the surface. I can't remember the state the green was in. The red and orange seemed to fade in less than a year.

This year I just did one more for another location. This time I used Versa Color as an integral color. It only took 6% to reach an intense orange called "orangered". 4% would have been a good orange as well, but we needed an extra 2% of primary yellow to push the proper shade. The Versa Color was spot on as ordered for a stain, but it needed to be tweaked to use as an integral.
*It may be a reaction with red pigments, not sure, but below the cream we again had air bubbles. It was easily handled with a quick slurry. You could never tell they were there after sealing.

This was a very expensive route but we needed integral color here. If you can stain it is much easier.

I'll attach a couple photos. The deep orange is Versa Color at 6%, the lighter orange is Delta at 10.5%.

I found a color I like. Local. Inexpensive. BUT

I started going at it 24 hours later with a 50 grit had pad, and I ended up tearing the Black BeUty sand right out. This integral pigment is designed for sidewalks and walls and stamped concrete.

Does anyone have any knowledge on how pigments affect set times? Or is that question specific to each type (or brand) of pigment? Without testing, I'm unsure of the strength of this concrete.

I used a 6% loading of pigment, Lehihigh white cement, silica fume, Trinic GFRC admix, and a heated blanket in my 41 degree shop....I mean garage.
Is that image white concrete with orange water base stain? Would you mind explaining a little about how you do it? What the sealer was? And how is holding up?

To all----I am very thankful for the willingness to share knowledge. I hope to do the same when my experience exceeds my lack there of.

6% of the cement only? that's a serious paste failure you have there. old cement? overloading of color? with a standard oxide type pigment there should no set retardation at a 6% loading of your cement. the Tech sheet for that pigment indicates you should not use that product with any "cement substitutes" like fly ash and slag. which is also interesting.

I'd be a little Leary of that colorant. just bite the bullet and order the right stuff already.
