Acid stain or dye?
They get sold as the same thing. They are not. One reacts with your concrete and one does not, and that single difference decides color, palette and whether it survives outdoors.
Why we will not promise you a color
Reactive stain takes its color from minerals already in the slab, so the same product on two floors gives two results. That is the appeal and it is also the risk. We test a patch on your concrete before anyone commits to a finish.
