Acrylic Staining Procedures Coloring/Stains

Our rock coloring system uses acrylic stains that have been formulated to bond to both our cast product and also stamped concrete or hand textured mortar areas.

The best way to apply the stain is to use simple spray bottles. For bigger projects, you will want to use pump sprayers. For strong color, spray stain on a dry surface but most of the time it is better to spray on a wet or damp surface. Use a wet sponge to dab away drips before they dry.


SHAKE THE STAIN SPRAYER before and during use. If the stain is not properly mixed the surface will appear shiny and may be slippery when wet. For one gallon and 5 gallon pails that have sat for several months, agitation with a drill and mixer paddle is recommended.

Use as little stain as possible because too many layers of stain make the surface look pasty and will age faster than light staining. Keep from freezing; stains have a one year shelf life.

Our acrylic stain is designed to add accent colors or antique artificial rock, but can be used for stamped concrete and other concrete products. It is not to be used as a base coat and then have other colors added. When that is done the lifetime of the coloring will only be a few years at most.

4 Basic Colors

  • Tan – Tan is a light beige color not strong enough for an accent but used to soften over colored areas. It can be used as a base coat if applied to a damp surface.
  • Rust – Rust is an orange-brown color used as an accent. It is usually the first color applied.
  • Reddish Brown – Reddish Brown is used as an accent for earth tones, sprayed on a damp or wet rock surface. If you apply this color and rust at the same time you can create different shades of brown.
  • Antique – Antique is a coffee colored brownish black and is used to make the rock look aged. The other colors must be dry but the rock surface should be wet when applying antique. Leave the color in the crevices and heavy textured areas but sponge off the excess color quickly or you will darken the entire rock area. Keeping the sponge clean is important; otherwise the color in the sponge is smeared over any surface it touches and it will leave a permanent shadowing.

Quart bottles are good for several waterfalls, gallons are needed for large projects.


Our modular products come with rust accents and antique applied to the off-white rock.


Reddish brown and rust accents make an earth tone color.

Custom colors are available, platinum gray is popular although our products are available with a natural gray concrete color by special order.

Generally, a sealer is not needed and makes re-staining difficult. Most sealers only last a year or less. Using Deck O Shield or similar clear sealer on coping or hand textured areas helps in freeze-thaw cycles and adds some protection from pool chemicals. It is also useful to protect coping during a concrete pour for a deck.
