Acid Stain is a chemical process. Hydrochloric acid and metallic salts react with the lime in concrete to permanently colorize the surface. Depending on the concrete and how the stain is applied, each floor will produce varying shades and intensity. The colors available in acid stain are subtle earth tones, such as terra cotta, brown and green. Neocrete also works with water-based penetrating stains, solvent-based dyes, tinted sealers and metallics to create an expanded range of colors. Almost any shade you desire can be yours.

For most jobs the stain process takes 3-4 days. This time frame is dependant on several factors, such as job size, the condition of the concrete, color, sealer and yes… Mother Nature! Acid staining is not glamorous, it is hard work. If you want a beautiful job that will last, hire a qualified decorative concrete contractor. If you are considering an acid stained floor, early planning is the best way to ensure a desirable outcome. Not all concrete is a good candidate for acid stain. Older, deteriorating concrete can be difficult to stain. Curing compounds, paint, sealers, glue, tape and adhesives can inhibit stain from reacting and must be removed.
