Make Custom Concrete Stone with Natural Color Shading for Pennies Each
This article is the result of one of our customers asking how to make a “sandy-yellow colored stone with brown and tan colored highlights so it will look like natural stone”. They went on to explain that they had seen that colored stone in a stone yard, and its cost was over $6.00 a square foot. They wanted to make the stone themselves to save money. They were able to duplicate the stone, and save about ninety-percent of the retail cost. Here are the instructions we provided. The basic techniques can be used to attain virtually any concrete colors you may desire.
The Basics of Manufactured Stone Making at Home:
Use a Mold Release to extend the life of your molds:
You should always use a mold release of some kind. It aids in de-molding your stone as well as prolongs the molds useful life. Spray or wipe your mold release into your molds. If using an oil release, just wipe out any excess oil to lessen the chance of what are referred to as bug holes. If using a water-based mold release, follow the instructions, and then wipe a bit of vegetable oil into your molds.
Add concrete color “dusting” to get the color-blending of natural stone you want:
Now pour your colored concrete mix into your molds:
Pour your mix in the molds and vibrate to lessen the chance of bug holes and bubbles in your stone, and to help compact your mix. Set the filled molds aside on a level surface and cover with a piece of plastic sheeting. Any kind of plastic will be fine. Leave the molds for at least 24 hours or more. The longer you leave them, the stronger they will be and easier they will come out of the molds. Temperature is a factor that helps determine the set-up time of the concrete. The warmer the temperature, the faster the concrete sets. De-mold your stone and you should have pretty close to what you are looking for--- sandy-colored yellow stone with brown texturing and highlights. If there are areas that are too dark or brown, you can rub a bit with your fingers to disburse the color more evenly. After de-molding, set aside to cure and dry. Don't worry, the color will get quite a bit lighter as it dries, but do not force dry. Interrupting the curing will cause the concrete stone to lose some of its strength. Ideally, keep the stone covered in plastic for at least a week after de-molding to aid the hydration and curing process.
Let us know how your stone turns out. Photos would be great in any case... good or bad. If you don't like the way the stone turns out, which I doubt will be the case, a photo will give us an idea of what went wrong. I've just done some tiles in the various colors to use as new color charts, so the Yellow or Buff should give you what you want... if it's too yellow for you... use the Buff color as the base. Buff is a little "tanner" than the yellow, but remember that the Brown "DUSTING" of the molds should tone the Yellow down quite a bit.
Manufacturing Stone with other natural-looking colors:
This technique can be used to attain just about any color or combination of colors you could want. If you'd like a gray base color with pinkish and gold tones like we illustrate on our websites with our Ledgestone, you would do away with any base color, and just use the “dusting technique” described above with Yellow, Brown, Red, and Black concrete color.
Good luck with your project, and please do get back to us with feedback as to how the coloring turned out for you. And we always like to see the results of our do-it-yourself training articles, so feel free to send photos of your projects.
