Bricks, Masonry, Asphalt and Concrete - Acid Stain vs. Colored Sealer

It's recommended that you seal concrete after applying an acid stain. However, I see there are also sealers that are colored as well. It seems to me the logical choice would be to just use a colored sealer and get the job done in one step; however, acid staining is still a popular choice for some reason. Is there some disadvantage to using a colored sealer to color and seal in one step instead of first using a stain and THEN sealing the concrete? Thanks.

It's like comparing apples to gorillas. They are completely different things.
Acid stain is not a coating. It is a compound that penetrates the surface, then chemically reacts with the chemicals present in the concrete. The chemical reaction is what produces the color, because there is no pigment in acid stain. The stain solution in the jug is colored, but that color has no relation to the color once the reaction takes place. For instance, Padre Brown acid stain goes on green, then turns reddish brown. Same for Terra Cotta. Amber stain goes on clear but produces golden/tannish/brownish tones. Black stain goes on orange. Since the color is caused by reaction, the color is as permanent as the concrete. Clear sealer afterwards greatly enhances and protects the color.
Colored sealer, on the other hand, is like a lightly pigmented acylic paint. It's a coating, and we all know how long that will last on concrete. A couple of years at best, then you'll need to re-coat. It won't give you the mottled/variegated colors that acid stain does either. If you apply it thick enough to actually color the concrete, it will be one flat color like paint.
Apples & gorillas.

Thanks for the info Pecos!
