Polished Concrete is considered one of the ways of an ecological and economical design flooring since it utilizes material that has already been in the place of construction.
They are really popular due to the low cost in their maintenance, longer lasting, and easier form of cleaning them.
Furthermore, they offer less slippery accidents than other floors since they have a high level of friction; plus they give no space for mold to grow, so the cases or allergies and other conditions associated to dust accumulation.
Light reflecting concrete
Although there is no any evidence of it, it is a popular clamor that polished concrete floors are a great source of reflecting light and the electrical devices can be substituted by natural lighting when there is a floor made with this material.
The life span of concrete
Some other advantages of this material is the high expectancy regarding its duration, it is a proven fact that floor made out of polished concrete has a useful lifespan of more than 100 years, if it is properly maintained. Besides that, cleaning this sort of floor does not require complex chemical products or very expensive wax brands; to keep your polished concrete floor clean you only need plain water and cleaner with a neutral PH balance.
Concrete grinding in 6 steps
The process of creating this kind of floor is quite similar to the one used to sand wood. With the usage of heavy-duty polish machines, such as concrete grinder, the floor is slowly grinded until the desired results are achieved. The resistance of this floor is given by adding a chemical substance during the moment of “dusting” it called hardener. This substance gets into the concrete creating a chemical reaction which hardens the surface and turns it into a dust proof floor. To get the best results, 6 grinding steps are required at least. Every one of these steps utilize a different kind of polisher, finer every single step.
Polished concrete levels
In order to know if the concrete floor in your dwelling is polished or not, there are some specifications that have to be taken into consideration. One of them is the level of grit achieved at the moment of grinding or polishing the floor; to be considered a polished concrete surface, it has to reach an 800 grit level as a minimum requirement. The best polished concrete floors are between 1500 and 3000 grit degree. To make this surface looks better some dyes can be added to provide it with some color with several options in its design such as scoring, radial lines, borders, and other kinds of designs.
The installation of this floor can be done in two different ways: creating a new one out of nothing or reusing existing material present in the house.
Requirements for a new polished concrete floor
The creation of a new polished concrete floor requires a series of demands that have to be covered, like a 3,500 psi or higher for the concrete mix. It has to be professionally done using power trowels and its curation has to be done using water for 7 days. The polishing of the new floor won’t start until the surface is complete cured, a process that can start on the 28th day after the installation of it. Another characteristic a floor of this kind should meet is a floor flatness level (or FF) of 50 or bigger. The retrofit floors requires less material in its construction, since the already existent material present in the house is going to be used; but the conditions of the previous material has to be in pristine conditions before starting building the floor.
Whether new or retrofit, polished concrete floor has turned into one of the most ecological-friendly material without a little, almost non-existent, damage to the environment.
