Classic Coatings Systems Traditional Decorative Acid Stain

Classic Acid Stain is a single component coloring solution of acidic metallic ion particles which when placed on the cementitious surface allows the metallic ions and 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.

Product Type: 1K (1 component) Coating

Compatible Substrates & Surfaces: Concrete, Masonry

Features: Cost Effective, Crack Resistant, Exceptional Peel, Low VOC, UV Stabilized

Identification & Functionality

Coverage

1 gallon (3.8 Liters) covers approximately 250sq. ft. to 320 sq.ft. May be diluted up to 4 parts water to 1 part stain for lighter colors which will yield greater coverages

Features & Benefits

Features

The  resulting  effect  creates  a  translucent, variegated and some times marbleized color. Considerable variations in color and tone normally result from the use of Classic Stain. Many special color effects may be achieved using different application techniques. Acid stains may give you unique looks and visual characteristics that cannot be achieved by using conventional polymer or pigment type stains. This is due to the acid reacting individually with each substrate depending on the cement’s content, age, porosity and the manner in which hydration takes place. These variables are the reason for its inherent beauty.

Applications & Uses

Compatible Substrates & Surfaces
Applications

Mist the concrete with water then apply a very light application of stain. The more stain that you apply the darker the color gets. To eliminate any brush strokes in the stain mist very little water over the brush strokes unless the strokes are desired in the finish. When the stain dries, spray a second coat on top for a darker color and more of a solid base. For a more diffuse look, you may wish to spray the stain onto the surface without brushing. Every slab of concrete is different, and staining is an artistic process so when available do small test patches on the surface corners so you can get the look that you like the best. Acid based stains cannot be cut with water thus making color lighter in shade because it will not bond to the surface. The best option is to test a small area of the concrete using full strength.  Cement content and weathering is another reason to do as many pre-stain tests as the job site will allow. Let the stain dry and processes. Different stains need different times to activate and fully color the concrete (generally 15 minutes to 1 hour).  Be sure and check your stains activation time before starting the job to insure full coloring of the surface. If you are going  for  the  most  color  from  a  giving  stain,  spray another coat  of  stain over the dried surfaces. Do not walk on the wet surfaces, the stain is active and can retain impressions of your feet or other marks from your tools.

Uses

Classic Acid Stain can be used anywhere architectural concrete is desired. Both 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 be used on both new and existing substrates. Typically used as flooring in restaurants and food service areas, bars, hotels, casino’s, retail stores, malls, art studios, movie theaters, museums, pool decks, automobile showrooms, residential flooring and more. Classic Stain may also be used as a means to color poured in place concrete; both smooth or with a form linear, tilt up wall, stone-face plaster, GFRC and faux rock.

Advantages
  • Protects and preserves the effect against wear and exposure when sealed
  • Multiple colors can be used for more interesting  images
  • Will not crack, chip or peel
  • Most colors can be used interior and exterior
  • UV stable and Low VOC
  • Low cost, easy install & low maintenance
Limitations
  • Must be neutralized with Classic C300 24 hrs. before sealing the stained surface
  • Will not hide moving cracks however, adds to their character
  • Must be installed over a clean dry surface
  • Atomic Blue, Palm Green & Aged Bronze should only be used in interior applications
  • If a uniform monolithic color is desired, Classic Acid Stain is not recommended.
