Is acid staining concrete a better option than a water born acrylic stain?
A. Not necessarily. Acid stains can be difficult to control and if you have concrete poured at different times from different suppliers there is a good chance that the reaction from the acid will be different across the concrete slab causing color variance across the project. Water born acrylic stains are controlled by the applicator and the results are largely driven by the skill of the installer versus the chemical reaction with the concrete surface. In addition, water born acrylic stain can be used to recolor existing stamped concrete that has been sealed and it can be used effectively indoors and out regardless of the concrete texture.
