Micro concrete flooring: application, types, advantages and tips.
Micro concrete is one of the most widespread continuous floorings in the world due to the decorative opportunities it offers for both indoors and outdoors. A coating that can be applied on kitchen floors, bathroom floors, terrace floors, etc.
A building material that, although it has years of history, has become much more popular in recent years, especially for covering all types of flooring. Here we show you everything you need to know about micro concrete flooring: how it is applied, its main advantages, the types of micro concrete available for floors, tips... and much more.
Benefits of micro concrete flooring
Applying micro concrete on floors offers countless advantages. Its continuity, high resistance to traffic and wear and tear, as well as its non-slip finishes, are some of the factors that make micro concrete flooring so popular for both indoor and outdoor spaces.
Below is a summary of some of the most important benefits that this innovative decorative coating can boast as continuous flooring:
- It does not raise the level of the floor too much thanks to its minimum thickness of between 2 and 3 mm.
- It is a continuous floor, which means that there are no expansion joints or joints. The entire floor renovation is done in one single piece.
- It adheres to any type of material without the need to remove the existing substrate. It avoids generating debris and heavy renovations.
- It is unalterable to UV rays and has very good thermal resistance.
- It has enviable resistance to traffic, abrasion and domestic cleaning products.
- No two micro concrete flooring are alike thanks to the variety of colours and finishes offered by this decorative covering.
- It can be used as interior flooring but also as exterior flooring, for example on terraces.
How to install a micro concrete flooring
Now that you know all the virtues of micro concrete flooring, it is time to explain the application process. Here are the six steps to take into account to install a micro concrete floor successfully:
1. Cleaning the future micro concrete flooring
The flooring to be covered with micro concrete must be in perfect condition. Therefore, the first step is to clean the future micro concrete floor of dust, stains, grease or any other type of particles, as well as making sure that the base is in perfect condition. It is very important to check the humidity level of the floor, wait for it to dry or apply an Primapox®100 Barrierto block rising damp or as a vapour barrier.
Once the surface is clean, apply a coat of primer on the flooring to enhance the adhesion between the existing substrate and the new micro concrete flooring. If the base surface is absorbent, such as concrete or self-levelling, PRIMACEM ABS should be used; if it is non-absorbent, such as terrazzo, tile or marble, PRIMACEM PLUS should be used.
3. First coat of micro concrete base
After priming, apply the first layer of unpigmented micro concrete base. The use of a fibreglass mesh is recommended, as it will help the professional to minimise the chances of cracks appearing over time. Once applied, sand the surface.
4. Second coat of micro concrete base
Once the surface is completely dry, apply a second coat of pigmented micro concrete base. In this step, choose the desired micro concrete colour to cover the continuous flooring and, once the surface is perfectly covered, sand the micro concrete floor.
5. Two coats of finishing micro concrete
The fifth step consists of applying two coats of finishing micro concrete or pigmented finish. Depending on the finish and the degree of slipperiness desired, medium or thick micro concrete can be used. As specialists, we recommend two coats of Microdeck, our medium micro concrete, which is optimal for the application of micro concrete on floors.
6. Micro concrete flooring protection
The last step in the application of micro concrete flooring is one of the most important. The micro concrete flooring is ready, now it needs to be protected. To do this, two coats of PRESEALER are applied by roller, followed by two coats of TOPSEALER. In addition to protecting the micro concrete of the floor, it can be waterproofed and even achieve an anti-slip finish.
Types of micro concrete flooring
If there is one particularity that perfectly defines micro concrete, it is its versatility, as there are different types depending on the texture and finish you want to obtain: one-component, two-component and ready-to-use. At Topciment we have up to four different micro concrete systems for floors:
Two-component micro concrete
Two-component micro concrete (cement + resin) is undoubtedly one of the most widely used in micro concrete flooring. For this reason, we have created two lines: Sttandard , the traditional and one of the most popular; and Unlimitted , the new range that provides smoother finishes and greater mechanical resistance.
