I was thinking if the big stores didn't have it I could call around to different places and could find it like a brick/concrete place. Just can't remember if I have ever seen it at HD before, I think they might just have white and that is it.
I don't know how many people are rolling in there looking for a specialty item like that, probably not many.
I just have this long flagstone path I "restored" and the stoop by the front door was butchered with nice concrete mix for the joints(yay!) that is pretty much impossible to get out without a ton of time and money. It has holes/gaps and I used the Gator Dust for the path but it won't work for how the stoop is laid out(it sits higher, all broken down nowhere for the sand to sit), need to touch up all the joints with a mortar to cover the abomination that is there now and need to get as close to a tan/beige as possible.
Oh and they are listing their house for sale and the realtor is taking pictures Monday, so I have a couple days to figure this out real fast. No pressure.
Home Depot, Lowes, or a brick supplier should have an additive in stock, either liquid or dry.
The hard part is going to be how much to mix to get the color you want. To get a light tan you might need to start with white mortar and sand.
That's not really uncommon at all. As mentioned earlier, all the brick companies in town here carry 70 lb bags of Buff, Light Buff, Tan, Etc Mortar. All you do is add sand, the portland is already in it. They generally have a huge collection of finished samples to color match with too.
