Different Types of Decorative Concrete
Have you ever wondered how the aesthetic effects are given to the architectural structures? Well, you got the answer now. We all are familiar with the necessity of concrete in the buildings of all sorts. Typical, uncolored grey buildings in the recent history of architecture were made of simple concrete, often coated with paint. These buildings added dullness and monotony to their surroundings until someone came with the idea of making them decorative. The simple concrete is given the aesthetic look by adding different materials while preparing the concrete mixture. Apart from being decorative, they can be useful for safety purposes such as to level the slippery areas by adding rough but artistic patches to it. These materials are often based on Stamped concrete, polished concrete, Engraving concrete. However decorative concrete is not limited to these processes only, there are many more ways to give an artistic touch to your houses, office buildings, schools, etc. Let’s find out how these mentioned aesthetic materials work.
The name itself indicates the process of stamped concrete. Before diving into the process, one should be aware of the purpose of stamped concrete. It is used to imitate wood, cobblestone, stale, brick, stone among all other types of materials existing in nature.
The process involves imprinting the molds into the concrete before it is hardened. Color can also be added to the stamped concrete to produce elaborated designs. The only problem with coloring it wears off in the sun with time. However that can be solved with renovation requiring minima, the cost compared to the maintenance of its natural counterparts like wood, brick, stones, etc. Hence being cost-effective it is highly preferred than the counterparts.
Concrete dyes are commonly known as wall paints. Concrete dyes are not a very old technique for adding color to the concrete buildings, floors, walls, etc. The setback of these dyes was that they had alcoholic agents in them due to which faded in a shorter period of time while being exposed to the sunlight.
However, in recent years improved and long-lasting dyes are being produced by using UV inhibiting agents. Yet there is a high chance of the new dyes to be fading by the rate of 5 to 8 % every year on average for being exposed to the sunlight.
It is an interesting concept. In childhood, we had rubber stencils to draw shapes from the play dough. The concept is very similar. The rubber imprints are engraved in the concrete before it is hardened. After the concrete is dried with the imprints intact, releasing agents already mixed with concrete preparation; help to keep the imprints from sticky to concrete.
In this process, Mechanical grinders and diamond pads are used to polish the concrete. The size range of grit varies commonly from 6 to 8500 grits. For concrete, it can only maintain shine up to 800 grit. The grit range for concrete can be raised to1800- 3000 by being treated with sodium lithium silicate. The concrete is then repeatedly passed over the grit diamond pad to achieve the glossy, shiny finish. Concrete dyes and acid staining are used to add color to get the finalized product.
Different types of logos designs and shapes are engraved in the concrete using tools meant for this task such as CNC concrete engraving. The existing concrete can also be remodeled through similar tools.
