Can You Stain Concrete That Has Already Been Stained?

Yes, you can stain concrete that has already been stained, however, the results may not be what you expect.. If you are trying to achieve a certain color or effect, it is likely that the existing stain will affect your results. You may also have difficulty matching the new stain to the old.

Concrete stains are classified into two types: reactive and nonreactive. Reactive stain (also known as acid stain) interacts with the surface of the concrete to generate a permanent colour.

It is made up of an acid and water solution and metallic salts that react with the lime in the concrete. This chemical process creates the color by forming a link with the top layer of concrete.

Acid-stained concrete provides a wonderful, marbled, transparent surface that some describe as having an old-world appearance.

Because a chemical reaction produces the color, there is no simple method to modify the color of acid-stained concrete; you may either place another layer of concrete on top and stain it an entirely new color, or you can add to the existing stain to deepen it and potentially vary the hue significantly.

Non-reactive or water-based stains are made up of water, pigment, and a binder such as acrylic or polymer.

How Do You Score And Stain Concrete?

A skill saw or a 4 1/2″ angle grinder with a diamond blade and a straight edge can be used.

Set the saw blade to roughly 1/16″ if using a saw. Measure your lines, mark each end with a pencil, and then mark the lines with a blue chalk line. Red chalk should never be used since it stains the concrete.

Make use of a straight edge of some kind (2 x 4 board, piece of angle iron, etc.) Score away while holding the straight edge firmly and at the right distance from the line to ensure the diamond blade is on the line.

Because your saw or grinder will not score to the wall, you need to carve an 8″ +/- border around the walls and carry your pattern scoring to the border lines.
