Product: Chroma Tech Acid Stains
Description: Whether for Old World beauty or Modern Sophistication, Floric Polytech’s Chroma-TechTM Acid Stain gives you the power to enhance concrete surfaces with unlimited colors and boundless character. The highest concentration of coloring salts in the industry provides rich, deep colors that are easily applied yet impart a dazzling range of hues and undertones through a simple dilution process.
Chroma-TechTM Acid Stain can be easily applied to enhance the beauty of architectural concrete anywhere, whether horizontal or vertical. Using different application techniques can result in a wide range of unique looks and visual character as the acid reacts with the available free-lime in the surface of the concrete.
Floric Polytech Chroma Stain is a single component coloring solution of acidic metallic ion particles (acid stain), which when placed on the cementitious surface chemically reacts the metallic ions with the particles in the cement (free alkali) to form oxides. These oxides become a permanent part of the substrate and will not crack or peel. The resulting effect creates a colored translucent, variegated and some times marbleized effect. For example, the formation of an iron oxide will produce a reddish brown mottled rust color. Considerable variations in color and tone normally result from the use of Chroma Acid Stain, and many special color effects may be achieved using different application techniques. Acid stains may give you a unique looks 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 is cement content, age, porosity and the manner in which hydration took place. These variables are the reason for its inherent beauty.
Typical Use: Floric Polytech Chroma Stain may be used in a wide range of environments interior and exterior on almost any cementitious surface, whether it be gray or Color Hardener Concrete, Stamped Concrete or Textured Concrete, micro toppings or Concrete Overlays. It can be used as an entire surface colorant or just as an accent border or detail. It may be used on both new and existing substrates.
Chroma Stain is typically used as Flooring in Restaurants and food service areas, bars, hotels and casino’s, retail stores and malls, art studios, and movie theaters, museums, pool decks and walk ways, automobile showrooms, residential flooring and anywhere architectural concrete is desired.
Chroma-Stain may also be used as a means to color poured in place concrete smooth or with form linear, tilt up wall, stone face plaster, GFRC and Faux Rock. Some projects are application specific, so be assured to do a mock up first prior to starting any project.
The Acid Stain may not be completely effective if the existing concrete is worn, old, previously sealed or has been washed with acid. In some cases, if a reaction cannot be achieved, the substrate may need to be resurfaced with a cementitious topping. The benefit to resurfacing is to provide a virgin canvas without the effect of patches, repairs, existing stains, mastics, glues, oils, etc. In some cases you may need to cover an existing old partial terrazzo or exposed aggregate floor.
What about uniform color? Because Concrete is not uniform, the reaction is not uniform, therefore the color is not uniform. Some areas are darker and lighter than others. If you were to view this product as natural Flagstone or marble, you have the idea, varying ranges of color tones with the occasional imperfection. The use of a cementitious topping whose hydration has been engineered, with installation and Curing properly controlled, may help narrow some of these variables.
Restaurants, bars, and food service areas - Hotels and casinos - Retail stores and malls - Art studios, theaters, and museums - Offices and lobbies - Family fun centers and amusement parks - Pool decks, patios, and walkways - Automobile showrooms Residential flooring - Walls and countertops - Faux rock walls Landscaping, faux rockscapes
Applications: Can be interior or exterior, on gray, Color Hardener Concrete, Stamped Concrete or Textured Concrete, even on Micro Toppings or Overlays. Three-dimensional effects can be made by sandblasting, scoring, and stenciling. Acid Stains can be used as an entire surface colorant or just to accent a design on the floor. It can be easily used to color poured-in-place concrete, as well as tilt-up walls, stone face plaster, GFRC, faux rock, or used in conjunction with polishing and densifying techniques.
Technically, Chroma TechTM Acid Stain is a coloring solution of metallic salts dissolved in an acid solution that, when applied to a cementitious surface, become a permanent part of the surface matrix. Depending on the preparation, many special color effects can be achieved as the salts react with and are absorbed into the porous surface. The result is a translucent, variegated and sometimes marbleized effect that will not crack or peel.
Why use Chroma TechTM Acid Stain rather than conventional Polymers or Pigments style stains? Beside being the most foolproof system of concrete coloration available anywhere, Acid Stain imparts a visual character that simply can’t be achieved by other methods.
Advantages
- The Penetrative reaction of the stain protects and preserves the effect against wear and exposure when sealed, the stain is not on top of the Concrete Surface, but permanently in the concrete.
- Depending on your application technique, multiple colors can be used for more interesting images.
- Complies with all applicable air quality management regulations (contains no solvents or pigments).
- Concrete Stains allow you the choice of intense or subdued color, offering new areas of profit and value.
- Most colors may be used interior and exterior in a wide range of environments.
- Conforms to ADA requirements for coefficient of friction (when sealed appropriately).
- Compared to conventional flooring, chemical Stained Concrete and toppings offer increasing saving capabilities for project value engineering and reduced life expected maintenance cost.
Limitations
- If a uniform monolithic color is desired, acid stain is not recommended.
- Dried residue is slightly acidic and care should be taken with waste management and proper neutralization.
- Will not hide moving cracks. However adds to there character.
- The stain colors atomic blue, palm green and aged bronze should only be used in interior applications, as they may continue to react with water and darken or blacken when exposed to excessive moisture.
- When these colors are used, the sub-grade must be well-drained and not subject to high moisture vapor emissions. The stained concrete must be protected from all sources of excessive moisture.
