I've never used the product, so no advice but going back to the company. But I can certainly understand your concern.

To be honest, I do not find the outcome of too much concern. It certainly does not appear pink to me, a color I detest and avoid anywhere in my life. Also, concrete does change color as it ages. I don't have a lot of experience with colored concrete but assume it would follow a similar aging progression.

As a professional landscape designer, I try to disuade my clients from installing extruded concrete edging for their planting beds. It's expensive, offers too much permanence and too little/insufficient flexibilty. Landscapes change with time and beds will increase or shrink over the years.

Like a chain link fence, extruded edging tends to devalue a landscape.

Hi Patricia Colwell consulting, my property is over an acre, about 2/3 of it is actual yard and the rest is left natural. So the majority of the edging is dividing lawn from field and there are a few beds of flowers and shrubs also. My husband and I older so we have had to make our property easier to maintain so that we can live here for hopefully many more years. I don’t see chipping in the photo unless you are talking about tiny chips along the joints? There is some dirt on the edging. At any rate, nothing that bothers me.

It's fine. An acid wash after its had it's 28 day cure would get the surface cream with the heavy pigment removed, and show more of the aggregate. That will tone it down considerably.

In your AI search, did you come across this article? You (or your installer, if he feels the mix was faulty), can fix the color. Hope this makes you feel better about the pink...I wouldn't be happy, either.

I think the installer needs to confirm that the correct ratio of color mix was used in the concrete. And what can they do to remedy the miss? We had a cement patio poured and then they stamped a brick edge around it so it was stained to go with our brick foundation. At first it was vastly dark, but the GC told me it would lighten up quite a bit within 30 days especially since it's in the full sun. He was right, and it's almost a perfect match.

In your case it appears the opposite because it's much lighter than the sample color for Sequoia Sand, so it obviously won't darken but will likely get lighter. I would see what they can do to remedy that. A cement stain perhaps?

Minardi, thank you for the suggestion of the acid wash, I will look into that. I once spilled full strength vinegar on color cement and it almost completely bleached the color, I assume an acid wash is gentler?

oncape, I did not see the article about that charming house. I don't see anything in there about cement color, just staining the fence? What am I missing? Thank you for the validation about the pink!

bearbev, thank you for the info about the correct ratio of color mix. I really don't mind (to a point) how light or dark the color is, only that it is pink, and I wonder if a cement stain can provide suffient coverage so that the pink doesn't show through? I'm afraid it might be hard to predict the outcome of a stain over the pink, it might go orange.

I've contacted the installer who will be coming to look at it, and I'm afraid will just say something like "it's in the normal range of variation." I've contacted the colorant company also, though I think it's unlikely the error was on their end
