Re: Charcoal Coloring To Existing Stamped Concrete


Using a charcoal material for concrete is a very bad idea. We made about 12,000,000 to16,000,000 concrete units annually. We used black iron oxide pigment for real permanent concrete products. We did make some landscape units for dealers with the understanding there was no guarantee on weathering and abrasion. I think the cost difference was about 40 to 60%.


We never, ever used a carbon based pigment for structural and/or architectural products.

Re: Charcoal Coloring To Existing Stamped Concrete


thanks everyone, i just haven’t found a charcoal pigment coloring that you add to water, spray on, let it dry and seal over. they understand it’s temporary since in a year they will do a full stain if entire area once sealer is warn down.

Re: Charcoal Coloring To Existing Stamped Concrete


If you're looking for something that settles out and lays in the joints/deeper depressions, this is ticket:

https://www.butterfieldcolor.com/pro...tiquing-agent/


It has a cementitious component to it, so it works best on new, unsealed concrete.

We use this stuff almost exclusively, as we've given up on the mess that's created from shake-on powder releases.

Re: Charcoal Coloring To Existing Stamped Concrete


thank you, this is exactly what am looking for but can it be applied to existing stamped concrete. There last person just pressure washed to clean, applied the water/color then let it dry then fresh seal. All water based. Will this do the trick?

Re: Charcoal Coloring To Existing Stamped Concrete


I think that you can add pigment to the sealer. Again, verify with your supplier.

Re: Charcoal Coloring To Existing Stamped Concrete


It's called antiquing agent.


Brickform makes some (it's basically just pigment like any other concrete color additive)


Apply detergent to the slab then pressure wash it clean, keeping the slab wet mix up the pigment and apply it with a broom using a swirling motion. Once it's fully coated, go get some lunch and let it dry completely.


Come back and reseal with a high gloss sealer and it will be locked in.


Don't use a water based sealer, use the good stuff only. If it doesn't require a respirator when applying, it's not the good stuff.

Same here, the dust is a huge mess, and can't be good for you.

Liquid release is the way to go for me. Adds a few steps the following day but totally worth it.


The only thing I like about the dust is how hydrophobic it is, you can generally start stamping a little earlier with it.

Yes, it can be applied to existing concrete, it's actually a great way to bring old stamp work back to life. The issues is that the sealer has to be pretty much non-existent and worn away.

No, doesn't sound like it if it was just sealed, especially with WB sealer. The stuff won't bond and will likely just bead up on the surface. I personally wouldn't touch the patio with a 10' pole if it has water-based sealer on it. Far too much risk for so little reward. Move on and let somebody else own this PITA job...........

We still use the powder occasionally, out in the boonies where there's no neighbors, on little stuff. I actually think the powder does a better job of creating variation, naturally. Like you, I find the few downsides of the liquid to fall short of the benefits of the liquid clear release.
