Stain-Crete Acid Stain is a deep penetrating acid-based chemical stain that can be used to color old or new concrete (which has cured for a minimum of 14-28 days).

Stain-Crete chemically reacts with cured concrete, Level Top SP or Micro-Crete to provide a distinctive permanent color with a subtly shaded marbled effect similar to the look of aged natural stone.  Stain-Crete's variegated finish will not peel, crack, chip, or fade.

Because Stain-Crete penetrates so deeply, it can be used for both interior and exterior applications.  It can be applied to both horizontal and vertical surfaces giving an attractive custom look to any masonry surface that, once sealed, is impervious to alkali, salts and salt spray, UV rays, and abrasion.

First Coat: Approximately 200 to 300 ft2 /gal (4.9 to 7.4 m2 /L). A second coat may be necessary for desired results.

Ask a Question
  • I have a slick surface concrete slab. I don’t want to grind the surface as recommended . What is the effect of not sanding or Grinding before stainIng or acid stainIng the slab ?

    grinding opens up the pores in the concrete so the stain has more surface area to react. If you do not do this, you are limiting the performance of the stain.

  • Can this be used on a brick wall and fireplace brick if I remove the sealant?

    It can be used on a wide variety of concrete surfaces.  I would suggest testing a small area first, but you should be ok.

  • Can this product be use on a brushed finish concrete patio ?

    The manufacturer suggests mechanically scarifying the surface to prep the concrete. I would suggest grinding the concrete.

  • I want to use Ardex feather finish over cutback to cover that up. Can I add your product to the ardex so not to paint?

    Ardex Feather Finish does not take stain consistently or evenly.  Check out Ardex SDm for a better option for staining, and as a final floor covering.  

  • Can this material work on Terrazzo to change the color?

    There are several types of terazzo, depending on the type, you may be able to use this to change the color.  If it is the poly or epoxy type, it will not work as it doesn't contain any cement component that the stain reacts with.

  • Can I use this stain on stone veneer? I am trying to darken the grout lines that are fading from grey to white but will be hard not to get on the stone veneer. Also I want to seal put a wet look on the grout and the stone veneer because all is fading. Which is best to use. I’m in Maryland. Thanks

    I would suggest testing a small spot of sealer on the grout before anything.  Chances are, the grout will darken back to the original look. 

    If not, you can apply the stain with a brush to avoid getting any on the stone. 

  • Does this come in any smaller size? I need very little

    How much do you need and what color?
