IMPORTANT NOTE ABOUT WHITE COLOR: Natural color of concrete depends mostly on color of sand and cement. That is why we only use brilliant white sand (and very clean stone, not to affect color) however, in our more than 20 years in business, we noticed that white cement tends to be more brittle and is not as reliable in the long run as the industrial standard, which is light grey. Although some companies offer white precast concrete products as the standard color, which may be ok in the south where winters are not as harsh, we advise against it. There are no white pigments, acid stains or bleaches for concrete. If you are sure you want us to use white cement for for your project to achieve a brighter color, be sure to seal it after installation. So perhaps a better option for a brilliant white concrete color is to paint it. Painting will create a uniform color but hide the often desirable concrete texture. Our standard concrete precast comes in slightly off white or what can be described as antique white color shown below. Color gets darker after the rain when wet and lighter as it dries out unless it is sealed. Sealing concrete is a simple process which preserves shade (from wetness) and also protects against weathering.
FOR COLORS OTHER THAN WHITE WE SUGGEST ACID STAINING: One of the advantages of quality concrete is the ability to use stain to match the color without losing the beautiful texture. You can find a variety of different concrete acid stains on Ebay, they generally cost about $50 for a gallon, which should be more than enough for a small project. Using two different colors such as sandalwood and ebony black, we have been able to match the color of our stones without much effort at all (see below).
