COLORING CONCRETE

Description of finishing techniques

Concrete Retaining Walls
Tunnel Portals
Bridge Piers and Abutments

It's real simple. No sealer, stain with very thin ink wash.

Just put a couple of drops of black India ink into about an ounce of tap water- and apply it with a cheap 1" wide brush. I just slop it on vertically.

Then weather with earth tone artist's dry-pigments.

Dry-pigments are just that, very powerful colorants that are added to binders (oil, gum, etc.) to make paints, chalks, etc. They are available at larger art supply stores. You only need a little. You can set it into the casting by applying more ink wash.

A common alternative is to grind up colored chalks.

It only took me a moment to color this bridge pier as described.

Did I mention that I used scale wooden forms to create my concrete stock panels? Here is a close-up of the O-scale stock.
The form planks are eight scale inches.
Same for HO but I did not bother with the nail impressions.
