Concrete Stains [Chemical/Reactive]

Patinaetch | chemical (acid) stain for concrete surfaces

Patinaetch is a mildly acidic water based solution designed to etch and stain concrete or masonry substrates. The chemical reaction with the substrate results in naturally variegated earth tones similar to the oxidation of a copper or the patina of a bronze sculpture. Unlike paints or coatings, Patinaetch does not cover the surface; it rather works with the existing surfaces and possibly highlights irregularities.

colour effects

Patinaetch comes in seven custom colors. The colors produced from these standard stains are unique to each concrete surface and could differ significantly from the color chart. Various colour effects can be created by…

  • Spray different Patinaetch colors on top of each other
  • Blend two or more Patinaetch colors prior to staining
  • Broad casting chemicals such as fertilizer, miracle grow, etc.
