CONCRETE ACID STAIN
Direct Colors Acid Stains for concrete are designed to enhance the appearance of concrete and other cement-based surface materials. It has been proven in thousands of commercial and residential applications to create a beautiful and unique flooring surface. Concrete Acid Stains produce unusual and permanent color effects in concrete, self-leveling topping systems, gunite, cement plaster, stucco, shotcrete, natural stone marble, cultured stone, limestone and other surfaces. Each concrete acid stain creates uneven color effects that simulate the natural shadings and aged appearance of stone or masonry. The color effect is unique to each stained surface and cannot be duplicated with other materials.
Most acid stains in the market are a mixture of mostly water, hydrochloric acid and soluble metallic salts. Direct Colors Concrete Acid Stains are composed of a unique concentrated formulation of blended metallic salts in an acidic water-based solution. These metallic salts penetrate and react with the minerals in the concrete to deposit the colors into the concrete pores. Each color is composed of a complex proprietary formulation that contains no pigments or resins. When highlighted with the proper sealer, this effect provides a natural and attractive glow that will not chip off.
How much acid stain do I need?
Direct Colors has taken the guess work out of your next project! but if you must know, you need about one quart of acid stain per every 100 square feet of surface if applying one coat. We always recommend applying two coats but if you are gearing toward the multi-color acid stain approach then the single coat of coverage ratio will work for each color.
If you are applying the recommended 2 coats, use our coverage calculator. This tool will not only tell you how much acid stain you will need but also how much sealer and floor wax you will require to complete a project.
Direct Colors Concrete Acid Stains are available in 1 qt (0.95 L), 1 gal (3.8 L), 5 gal (18.9 L) and 55 gal (208 L) containers.
Acid stain is a translucent product and the overall effect of the stain system leave an element of unpredictability to the final appearance of the applied stain. For this reason, our color chart is to be used as a guideline only. Testing small areas or samples prior to starting a project is always recommended since the final color may differ significantly from what is shown on the chart due to a number of factors, including, but not limited to the age of the existing slab, mix design, finishing techniques, concrete base colors and surface permeability.
Direct Colors Concrete Acid Stains are available in 10 standard colors. Use our Design by Color photo gallery for color combination and technique ideas.
Different stains require varying amounts of time to activate and fully color the concrete, generally from 2 – 8 hours. Use our Acid Stain Color Activation Times chart for details. Be sure to check the acid stain color activation time before starting a project to ensure full surface coloring.
For the most color from a given stain, spray another coat over the dried residue.
NOTE: Azure Blue and Avocado Concrete Acid Stains should never be applied to a wet or damp surface, as this will produce a black or brown spotted appearance to the surface. Azure Blue and Avocado Concrete Acid Stains are recommended for indoor projects only.
