11 Proven Concrete Color Recipes

Much like the right mix for Grandma’s homemade apple pie or Mom’s hearty chicken noodle soup, a recipe for a beautiful concrete stain requires just the right ingredients, in just the right amounts and in careful applications.

We asked contractors and manufacturers to share a few of their favorite concrete concoctions.

Here’s what they said:

The color on this slab was created with an Oyster White base and Weathered Sage release agent. The texture was achieved using two rock stamp patterns, one with impressions of trilobites.

1. Sandstone/Weathered Sage Color-Texture Combination
Tom Ralston Concrete — Santa Cruz, Calif.

Ingredients:
Concrete: Six-sack 3,000-psi mix design (in California use Type II cement)
1,650 pounds 3/4-inch angular rock
3-inch to 4-inch slump of water (39 gallons/yard)
1 bag of stealth fiber mesh (1 pound)
Allow 2 percent to 4 percent air entrainment in the mix to improve workability and flowability, or allow up to 5 percent in areas prone to freeze-thaw.
Matte stamps (Italian Slate pattern)
Alcantar Oyster Shell color hardener
Alcantar Sandstone color hardener
Alcantar Weathered Sage release agent

Directions:
Pour concrete. After bleed water has left the surface, broadcast Sandstone color hardener over entire surface. Wood-float for “mechanical bonding” of color hardener and poured concrete.

While concrete is making its first set, deep-score border bands of any width, generally 12 inches wide.

Apply Oyster Shell color hardener to all concrete, including border bands. Swirl-trowel or hard-trowel the bands.

As surface hardens, apply Weathered Sage release agent to the interior panels (within the bands), then apply matte stamps. A shallow, light slate or Italian slate texture is popular with customers. Sometimes we will combine matte stamps for a unique, one-of-a-kind texture. Let stand overnight.

Use a power washer to remove release agent from the surface of the panels.

If you want to acid-wash to create a worn, weathered look, use a solution of 1 part acid, 8 parts water, carefully masking off any panels not to be acid-washed. Let stand overnight.

For exterior surfaces, seal with recommended lacquer sealer to enhance color combination.

Texas Tuscan concrete floor how to and recipe L.M. Scofield /Los Angeles, Calif.

3. Texas Tuscan
L.M. Scofield — Los Angeles, Calif.

Ingredients:

1 Pennsylvania Slate Pavecrafters tool set
(30 single-stone Prestige tools varying in size from
6 inches by 6 inches to 3 feet by 4 feet)
Arizona Tan Lithochrome color hardener
Russet color hardener
Terra cotta color hardener
La Crescenta Brown release agent

Directions:
Pavecrafters tool set allows for random pattern layout in variations that do not appear to repeat, and the result looks like custom hewn-stone work. After base is imprinted, use Lithochrome color hardener to provide a rich paste that gives decorative concrete patterns a crisp edge. Broadcast high-opacity Arizona Tan and work into upper layer of concrete to improve density and durability for vehicular traffic. Randomly distribute Russet and Terra Cotta color hardener over surface, then float and trowel into concrete. Use colored powdered release agent in La Crescenta Brown to clean and release concrete stamping tools and add depth to pattern.

This project is an award winner in the 2006 Concrete Pavement Awards for “decorative and durable designs” using cast-in-place concrete.

7. General Coloring Instructions
Specialty Concrete Products — West Columbia, S.C.

Instructions:

Consider pattern (if stamped concrete or stamp overlayment).
Use color schemes that replicate natural materials. For a cobblestone pattern, use a light-to-dark gray scheme. Use sable as the main color, marbleize in Philly blue and sun gray, and use charcoal release agent. For a random stone pattern, try a light-brown-to-dark-brown scheme. Use adobe buff as the main color; marbleize in autumn brown and desert tan, and use walnut release agent.

Choose colors that complement and do not clash with building colors. Do not try to match construction color; it is difficult to do and often too overwhelming if successful.

Take the same factors into consideration when using multiple release agents and stone shading.

Starting with a light main color and using darker release agent and stone-shade colors yields a nice effect.

When acid staining with color hardeners, use white or antique white for main color; marbleize in light grays (pewter, sable) or light buffs (adobe buff and sun buff).


8. Marbleizing with Multiple Color Hardeners
Specialty Concrete Products — West Columbia, S.C.

Instructions:

Choose one prominent color shade. Other shades of color hardener within the same family will provide highlighting/marbleizing effect.

Per manufacturer’s instructions, work in primary color hardener. Finish final pass to desired surface profile.

Randomly broadcast all but one of the remaining colors across the surface, taking care not to create a repetitive pattern. Work colors into surface from different angles. The less the colors are worked in, the starker the difference between the main color and the highlights; the more they are worked in, the more subtle the highlights.

Apply the final color over the entire job, creating a uniform antiquing color, especially within grout lines.

This technique can be used with the main color being an integral color.

9. Multiple Release Agents
Specialty Concrete Products — West Columbia, S.C.

Instructions:

When using several colors of release agent with a single color hardener or integral color, for best results, apply release agent colors over a lighter main color. Work in main color with color hardener or integral color. Take finish to desired surface profile. Broadcast several release agent colors across the surface, alternating handfuls prior to stamping.


10. Color Hardener & Acid Staining
Specialty Concrete Products — West Columbia, S.C.

Instructions:

The following technique allows for use of a spectrum of light color hardeners to create a lighter marbleized surface to acid stain. A brighter, more vivid acid stain with more color variation will result. This can be used over stamped surfaces or smooth finish surfaces.

— Work in multiple colors of color hardener. The very light color spectrum is best.

— Allow concrete to cure per manufacturer’s recommendation.

— Acid-stain concrete

11. Stone Shades
Specialty Concrete Products — West Columbia, S.C.

Instructions:

This technique uses translucently pigmented seal coats (SCP Stone Shades) to provide a custom shade over decorative work. Use to shade individual portions of a job or the entire job.

— Apply one coat of seal to wet out colors. This helps keep the Stone Shade in a liquid state so pigmentation can flow in the film and create desired highlights over textured surfaces.

— Apply final coat of clear seal.

— Allow final coat to penetrate into first coat so pigmentation rises to close to concrete surface.
