PRODUCT DESCRIPTION:

QC Patina Stains are made of various combinations of metallic salts in slightly acidic water-based solutions. They lightly etch and penetrate "bare" new or existing concrete and chemically form permanent insoluble colored precipitates which remain in the concrete's pores. These stains may also be used to treat other cementitous materials (such as terrazzo, certain self-leveling & other toppings, gunite, shotcrete, stucco and cement plaster) as well as natural stone with a chemistry similar to concrete s (i.e. marble, limestone, etc...). QC Patina Stains produce an effect similar to a sculptor's patination of bronze or the natural oxidation of a copper roof. A varigated finish including broad drifts in color is not considered a defect but is, in fact, a reason for choosing this method of concrete coloration.

Available in 1, 5 & 55 gallon units, in 8 standard colors which may be reduced or mixed to yield additional colors. This is not a paint or a coating! It does not "cover-up" but blends with the color of the substrate. Substrate color may also be modified (via QC's Color Hardeners or Integral Colors) to yield the desired color. Artistic effects, such as 'bleeds" or the use of "resists" are possible.

Application:

The substrate must be "bare" with no sign of material that would act as a resist to staining. It's a good idea to test the surface to be stained by spraying lightly with water from a pump-up sprayer. Potential problems are areas which do not "wet" uniformly. Experienced applicators often disc sand the concrete substrate to enhance the grain and open up the pores by the use of a rotary floor machine with a disc sanding attachment ( experiment with a variety of sandpaper grits...the idea is to raise cement dust without scratching the surface). The stain is generally applied through a pump-up sprayer or hand-operated sprayer, at a rate of 200 - 400 square feet per gallon, per coat. This is followed by massaging the stain into the surface with a stiff nylon-bristled brush, in a circular motion. As the stain is applied you will notice an acidic "fizzing reaction. This is generally a sign that the substrate is accepting the stain. The stain should always be applied in 2 or more coats. After the first coat, additional coats may be applied after the previous coat has dried or, if not dry after 4 hours. If coats dry unevenly, "brush-out" any excessive puddles. After final coat has dried or, not dry after at least 4 hours, remove the residue by spraying with water and agitating with a stiff nylon-bristled brush. Experienced applicators will use a hose with a "trigger nozzle", a rotary floor machine with a "pad-driver" and the appropriate pad. (Coarseness determined by experimentation). Rinse until rinse water runs clean. Rinse water may have an additional coloring capacity. Control and/or collect and keep-off surfaces not to be stained. Squeegees and/or wet-vacs are recommended. Depending on circumstances, rinse water may need to be collected and properly disposed of. Always consult our MSDS and appropriate agencies for direction!
