The resulting effect creates a colored translucent, variegated and sometimes marbleized effect. Considerable variations of color and tone normally result from the application of Acid Stain. Acid stains may give you a unique look and visual character that cannot be achieved using conventional polymer or pigment type stains. This is due to the acid reacting individually with each substrate depending on its cement content, age, porosity and the manner in which hydration took place. Application: Acid may be used in a wide range of environments interior and exterior on almost any cementitious surface, whether it be gray or color harden concrete, stamped or textured concrete, micro-toppings or overlays. It can be used as an entire surface colorant or just as an accent border or detail. It may also be used on either old or existing substrates. Typically it is used as flooring in restaurants and food service areas, bars, hotels, casino's, retail stores, malls, art studios, movie theaters, walkways and anywhere architectural concrete is desired. Acid stain may also be used as a means to color poured concrete smooth or with form liner, tilt-up wall, stone face plaster, GFRC and faux rock. Test Sections and Mock-Ups: Staining and antiquing are expressions of individual talents and techniques. Experimentation with colors and application procedures are highly recommended prior to tackling a project with this product. It is recommended that samples and mock-ups are used. Representative test sections should be conducted and signed off for approval by the owner, and even then variation should be expected as substrate free alkali levels change (which effect final color). Cleaning of Flat work: Use a heavy-duty rotary floor machine that operates at approx. 175 rpm and is equipped with a brush or with a pad-driver. Use a suitable commercial detergent, bristled brush or janitorial pad on standard concrete (however take care as not to catch or scar the surface with too aggressive brush or pad). Newly Placed Concrete: New concrete must be protected from damage and allowed to cure a minimum of 14 days. Do not use liquid curing materials. Cure concrete flatwork with new and unwrinkled, non-staining curing paper. Cure all surfaces by the same method and apply the chemical stain when the concrete is at the same age. Immediately prior to stain application, clean the cured concrete thoroughly. Sweep the surface, then pressure wash or scrub with a rotary floor machine and detergent. Existing, Older Concrete: Existing or old concrete must be completely clean and penetrable. Pressure wash or scrub to remove dirt. Sandblast concrete that has been preciously coated with liquid curing materials, paints, and coatings. If the chemical stain does not react on dense, hard- troweled floors, open the surface by light sandblasting or terrazzo grinding. After rinsing and drying, inspect and test the surface for penetrability. Manual Application For Small Areas: Use a professional grade acid resistant brush, with uncolored nylon bristles of medium stiffness that has the ability to hold liquids. Transfer the stain solution to the surface and immediately scrub in with a brush. Note: Do not use push brooms, mops or rotary floor machines for applying stains. Containers used for transferring material must be acid resistant none leaking, such as plastic pails (do not use metal container). Scrub the stain solution into the surface using a circular figure eight motion keeping the brush in contact with the concrete and in continuous motion. Gradually spread the solution until all fizzing-action ceases. Brush solution back over the section just treated. Neutralize: After the final application has remained on the surface for a minimum of four hours, remove all residue by wet scrubbing with a detergent, then rinse until the water is completely clean. Neutralize surface with a diluted solution of 1 pint ammonia to 5 gallons clean water - followed by a thorough rinsing with clean water. Caution : Check the pH of the surface using a litmus strip or pH pencil. It should be in the range of 10-13 pH. Coverage : 200-400 ft²/gal/per application. Color and coverage will vary depending on porosity, texture, and age of concrete. Minimum 2 applications are normally required. 1 application may reach desired finish.
