Eagle Acid Stains create marbled variations of color on cured concrete by chemical reaction with the minerals in the concrete. Every concrete floor will react with its own unique pattern. Once sealed with clear sealer, your floor will pop with an elegant look. Acid Staining is a tedious process. Eagle concrete dyes should be considered if a simple process is important.

Questions & Answers

Can I use on concrete countertops outside
ByAug 2, 2025
1 Answer | 
Answer This Question

Acid Stain can be used on any concrete surface. Be sure to clean and neutralize the acidic residue after staining. Avoid using Jade, Aquamarine, or Patina color, as they are not UV stable.

    Can I use this for a concrete birdbath?
    ByApr 26, 2023
    1 Answer | 
    Answer This Question

    Eagle Sealer Acid Stain was not designed or tested for use on or in birdbaths. Our Acid stain will react and stain concrete, but likely not hold its color if a waterproof sealer is not applied.

      What will happen if I forget/don't neutralize it?
      ByApr 20, 2023
      1 Answer | 
      Answer This Question

      If you have not neutralized the surface, there may be a long-term bonding and appearance issue, as the acid will continue to attack the concrete and attack the sealer if applied.

        Can this be used on concrete blocks?
        ByApr 17, 2023
        1 Answer | 
        Answer This Question

        Yes, the acid stain can be used on acid blocks, however, the results may vary from what is shown on the color brochure/website. I recommend doing a test spot. Sealing the concrete blocks may be difficult if that is the end goal.

          Can this be used on concrete stone veneer? Looking to match/get closer to a black color. See attached photo
          ByFeb 6, 2023
          1 Answer | 
          Answer This Question

          Our Acid Stains will possibly stain any material that has cement; however, the mix ratios, admixtures and finish will effect how the stain reacts. Test areas should always be preformed with acid stains to determine reactivity and color. Also, Onyx is not black. Black is not a color that can be achieved with acid stains. Onyx is a concentration of brown that can give the illusion of black on the right material or it can also look very brown.

            1 Answer | 
            Answer This Question

            A polycuramine coating can be applied over the acid stains. Make sure you clean all residue and properly neutralize the stain before applying the sealer

              How many gallons for 1800 sq ft...what else is needed.
              ByJun 23, 2021
              1 Answer | 
              Answer This Question

              The Acid Stains cover between 200-400 square feet per gallon depending on the finish and porosity of the concrete. Also, depending on the finish of the concrete, the Etch and Clean may be needed. Our Cleaner Degreaser Neutralizer is necessary to neutralize the stain and a sealer is recommended. The choice of sealer would depend on finish of the concrete, location and desired look. Reach out to us through our website and we will be happy to further assist you. www.eaglesealer.com/contact

                I have very wide, WHITE grout lines and hate it. I want something that will penetrate the grout, not a paint product. Any idea how this would work?
                ByJan 18, 2021
                1 Answer | 
                Answer This Question

                There are specific dyes made for changing the color of grout and they would be a better choice than an acid stain. We would not recommend our stain for that application.

                  I am awaiting a replacement or return. But, either they mislabeled my gallon or it just failed. I ordered onyx (black) and the concrete turned an ugly dark "poop" brown & darker brown with more passes. Very disappointed!

                  Stain worked as advertised. We followed the directions and video.
                  Final color after 2 coats is a dark oil rubbed bronze color.

                  Ruined my concrete project
                  We bought the expensive rapid set concrete and the additives to make a concrete top for a desk. I bought black onyx stain for the desk top expecting black or atleast a dark gray. It turned out to be brown rusty color. We applied a thicker coat thinking maybe itd be like wood and turn out a little darker, but didnt change the results. It looked awful. Out of about $350 bucks in this project bc of stain. DO NOT BUY

                    Outside porch
                    I used this to stain new cement for a porch. It definitely started out more brownish then block. I gave the lighter parts two coats applying with a broom and not a sprayer. I wanted the more marbeled look. Then on the darker areas I did a couple more coats putting it on evenly with the broom. I had to wait for the right weather for sealing it and it seemed to actually darken some along that time. After the nutralizing it seems it is consistent. We have sealed it now and I could not be happier. You just have to realize cement has it's own characteristics and does not always do exactly what you think it will.

                      I used this product on Rapid Set High Strength Mortar Mix, with Flow Control and black tint according to the mixing instructions. The result of this starting point was dark gray. The Eagle product was touted as an acid stain that would turn your fresh mortar "onyx" and some reviews said that the results would be "black." One even said, "When you put this product on, you will think, 'This will turn out brown.' ... but trust us, the results will be black." Well I'd say this is half true. I did think it would turn the high-strength mortar I'd used for my pizza oven tabletop brown, and it did. It's nowhere near "black." The attached picture shows the unfinished result wet with water. The final is a dark, smooth dull brown ... about the same shades of brown. It did make the tabletop a variegated dark brown though, and as it turns out, it is a very pleasing effect. And probably better then either the dark gray of the raw mortar or the black I'd envisioned. An interesting outcome, and one I'd probably use again on another project.

                      I was not able to order this color from your website because it kept saying that it was out of stock. I called the company and that was in fact false. I ordered it directly through the company at a cheaper price.
