What You Should Know About Coloured Concrete

Colour brings life to any piece of artwork. It is good to note that colour takes a leap from just being those vibrant additions to masterpieces to a reliable partner when it comes to beautifying anything. In the world of structures, coloured concrete also exists. Learn more about how such materials can help with your construction job by being familiar with some facts about coloured concrete.

It all started in the 1950s

Coloured concrete has been in existence a long time ago, particularly in the 1950s. It was first introduced by California’s famous Davis Company. Back then colour comes out of the concrete after adding synthetic iron oxide to it. Synthetic iron oxide was commonly available simply because it was a waste product that comes from chemical manufacturing. This component was actually a coloured powder that brings out earth tones to the once grey concrete you have been used to.

Understand that adding colour to concrete is entirely a different thing

Some of you may say: Why add colour to concrete when you can just paint concrete, dye or stain it afterwards? Well, you have to understand that the coloured concrete product is not a result of painting, dyeing or staining. You have to remember that coloured concrete comes from a combination of pigments that have either been mined from the ground or those that have been made through chemical plants. If you are to add colour to your concrete, products are available in various forms namely liquid, powder and granular.

You have to control some elements that may affect the colour in the concrete

If you are planning to experiment on mixing colour to grey concrete on your own, you have to remember that you should be familiar with how you can control certain elements that can affect the colour you want out of the material. Water, for instance, has to be controlled so that it mixes well with the concrete and gives you just the right colour you want out of it. You have to remember that the more the water you add into the cement-colour mixture, the more likely that the colour outcome will be lighter in shade than what you expect.

Learn what you can use to make the colour better in several cases

If you are adding colour to the cement mix and it is hot or windy outside, expect that water can compromise the result. In this case, you have to make use of what is called a surface evaporative control agent. The good thing about using this in the mix is it does not merely focus on how you can work on the colour you want when it is windy or humid in the outdoors. It can also help provide a better finish on the surface just so it will not dry too fast.


It is good to note that you do not have to go through all the hard work just to achieve colour in your concrete. There are ready made items like our mini mix concrete. Feel free to browse our pages to learn more about such products!
