The natural color of DURHAM’S ROCK HARD Water Putty® is a light ivory. But you can give it any color you wish, here’s how …
Color DURHAM’S Water Putty® throughout before mixing it with water by adding powdered tempera or dry earth powders such as umbers, siennas, and other colors. Acrylic, latex paints, RIT®, Tintex, and coloring matter which will mix with water are also suitable. Do not use oil-base products, since oil and water do not mix and the putty will not harden.
Be careful if you need to add a great deal of coloring as it may affect the hardness of the dried putty.
Check hardness by experimenting with a little bit of DURHAM’S and the desired coloring agent before you start your project.
If you don’t need the color all the way through your project, you can paint DURHAM’S Putty after it has dried. In fact, you can use water-based or oil-based paints on dried DURHAM’S.
One fun technique is to apply two coats of shellac thinned with alcohol. While the second coat is still tacky, bronze powder or dry colors may be dusted on. Or wait until the shellac is dry and apply a thin wash of oil paint thinned with turpentine. Acrylic paint may also be used, but the surface should be primed first with an acrylic primer.
Interesting effects may be obtained by applying a bronze solution over or under washes of acrylic or oil paint. Your art, craft, or hobby store can supply glazes for giving various antique effects and can usually offer other helpful suggestions.
Stain cannot penetrate dried DURHAM’S Water Putty. If you wish to use stain for color, mix it with DURHAM’S when you make your batch.
For exact colors, weigh DURHAM’S powder and the paint in exact proportions. Sometimes, DURHAM’S can get compacted during shipping and the 3-to-1 mixing ratio may be skewed by compacted powder. Return to top.
