What is micro concrete? Uses, types, application and advantages.

Micro concrete Topciment is a decorative coating composed of cement, water-based resins, additives and mineral pigments that can be applied on a multitude of vertical and horizontal surfaces thanks to its great adherence. This construction material stands out because it is applied directly onto existing materials: tiles, plasterboard, floor tiles, marble, terrazzo or plaster, among many others. With hardly any work and a thickness of only 3 millimetres, a rapid renovation of spaces is achieved.

A cutting-edge cladding, jointless and suitable for both outdoor and indoor spaces. A continuous cladding that can be applied on floors, walls, stairs, ceilings, swimming pools and even furniture. Its versatility has led to its increasing presence in the refurbishment of private homes and in commercial premises and large surfaces such as sports centres, industrial buildings, hotels and restaurants.

Topciment offers you a wide range of possibilities and decorative finishes, where you set the limit. Give rooms a unique and personal character thanks to the different textures (thick, medium or thin); the wide variety of micro concrete colours; and the different finishes that our varnishes and metallic coatings allow.

Where can micro concrete be applied?

The decorative solutions of micro concrete are infinite. That is why its uses are so varied. From micro concrete stairs or micro concrete swimming pools to furniture clad with Micro concrete. Although the use par excellence of micro concrete is in floors and walls of kitchens, bathrooms and outdoor spaces such as terraces.

Whatever the surface to be covered with micro concrete, at Topciment we care about the final result. That is why, in our desire to achieve an optimal, versatile and quality product that lasts over time and adapts to the needs of the market, we have achieved a balance between hardness and flexibility.

And what does this mean? That our micro concrete allows us to cover any surface, no matter how large it may be, achieving a continuous pavement without joints or fissures. In this way we avoid areas of dirt, thus facilitating cleaning and disinfection, helping to obtain places free of germs and bacteria. In addition, our micro concretes guarantee a high resistance in the areas most exposed to traffic as well as to the most aggressive cleaning products. Hence the high demand for micro concrete in kitchens and micro concrete bathrooms .

Micro concrete frequently asked questions

1. What is the resistance and hardness of micro concrete?

One of the particularities of micro concrete compared to other decorative coatings is its high resistance and hardness. In the cases of Sttandard Microdeck, Sttandard Microstone and Evolution Microdeck, they can even be used in high traffic areas.

Many factors can influence the resistance and hardness of this coating, such as: the substrate on which the micro concrete will be applied, the type of micro concrete selected or the sealer, among others.

+información

Mechanical resistance
Micro concrete resistance to impact: Although micro concrete is a relatively hard material, resistance to impact depends to a certain extent on the hardness of the substrate. micro concrete, due to its low thickness, will deform in the event of a strong blow if the support is deformed.

For example, if we apply micro concrete on plaster and the base is deformed because it is not very resistant, the micro concrete will also deform. On the other hand, if we apply micro concrete on terrazzo or similar substrates, the resistance of the micro concrete will be greater.

Resistance of micro concrete to abrasion and wear: The resistance of micro concrete to abrasion or wear also depends on the type of micro concrete and the sealant used. Topciment has three continuous floor coverings available: Sttandard MicroDeck and MicroStone, Evoluttion Microdeck and Efectto Medium. All are coatings with selected aggregates of larger particle size, making them more resistant to compression and abrasion.

Sttandard and Evoluttion Microfino or Efectto Small, due to their lower resistance, are reserved for wall cladding. As for the sealers, although the resistances are the same, the higher the gloss, the more visible the wear marks are. Matt finishes do not reflect light or reflect it minimally and satin finishes are the most natural.

Chemical resistance
Resistance of micro concrete to stains and liquids: The resistance of micro concrete to stains and liquids will depend on the sealant used to protect the coating. The sealer is the final layer of the micro concrete application, which is what makes it waterproof and protects it from stains. Our Topsealer sealers are highly resistant to stains and liquids. According to the different tests carried out, Topsealers protect against oil, cola, red wine and similar stains.

Micro concrete stains from vinegar or lemon juice leave slight marks after two hours of exposure. This surface is affected by acid just like marble, although if we act by cleaning quickly, no marks will be left. Stains from salfumán, pure bleach, acetone and ammonia leave marks after half an hour of exposure. However, if we clean the micro concrete quickly, no marks will be left. The texture of the micro concrete and the difficulty of cleaning must also be taken into account.

2 On what substrates can micro concrete be applied?

Micro concrete can be applied on almost any type of substrate: cement mortar, self-levelling mortar, terrazzo, marble, tile, plaster or plasterboard. Micro concrete can also be applied on vertical and horizontal surfaces, in interior and exterior spaces. A versatility with which we can create micro concrete stairs, micro concrete bathrooms, micro concrete kitchens and even micro concrete swimming pools.

Yes, micro concrete cannot be applied on natural wood or supports formed by pieces that can expand differently.

+information

One of the main properties of micro concrete is its high adherence. Thanks to this, it is possible to apply micro concrete on tiles, speeding up renovations and avoiding the removal of the original covering. As long as the tiles are firm and not loose. In these cases it is necessary to use the mesh to support the support.
See the method of applying micro concrete on tiles with video tutorial.

Optimal conditions and state of the surface to be coated
The preparation of the substrate is as important as the application of micro concrete. If the substrate does not meet the necessary conditions, we will not be able to apply the micro concrete with guarantees. The surface must be level, consolidated, free of dirt and with a humidity level of less than 5%.

If the substrate on which the micro concrete is to be applied is a mortar, it must have set for at least four weeks before applying the micro concrete, in order to control any cracks that may appear during the curing process.

micro concrete piscinas
At Topciment we have developed Atlanttic, a line of bi-component micro concrete designed exclusively for spaces in permanent contact with water such as swimming pools. Micro concrete swimming pools are a trend and will continue to be so due to the many advantages of this decorative coating. Here you can see some of the swimming pools covered with Atlanttic .

Micro concrete on natural wood or parquet
Parquet or natural wood floors have a large number of joints, the boards expand in different directions causing tensions that are difficult to control, which can cause cracks in the coating, so they are not suitable for applying micro concrete directly on them. In these cases it is necessary to lift the existing floor and prepare the substrate before laying the product.

3.can micro concrete be applied over underfloor heating?

More and more people are choosing to install underfloor heating. But can micro concrete be applied over underfloor heating? Yes, micro concrete can be installed on underfloor heating without any problems. It is necessary to follow a protocol for switching on the heating to prevent cracks caused by temperature changes in the screed from being reproduced in the Micro concrete.

+information

The switch-on protocol is as follows:

1. Switch on the heating at least 4 weeks after laying the cement mortar.

2. Maintain the inlet water to the circuits at 25°C for 2 to 3 days. Then gradually increase the water temperature to 45 °C and maintain it for several days.

3. Turn off the heating at least 48 hours before starting the installation of the Micro concrete. The maximum floor temperature should be 18 °C.

Micro concrete flooring should be applied on cementitious mortars that have reached an advanced setting stage. This occurs after three to four weeks, depending on the weather. In any case, we must ensure that the mortar is practically dry. To do this, there must be a maximum of 5% humidity in the substrate, which should be checked with a relative humidity meter.

We recommend using quality self-levelling cement mortars.

Supports with powdery mortars are not suitable as the state of the application base must be consistent, otherwise it will be necessary to consolidate it.

After applying the micro concrete, we must wait at least 48 hours before gradually switching the heating back on (+5 °C each day).

Always change the temperature gradually at the beginning and end of the heating period.

Make sure that the relative humidity in the rooms is not too low.

Always avoid heat build-up caused by carpets and rugs or a lack of space between the furniture and the floor.

Important! Between the screed and the vertical walls there will always be an expansion joint so that the screed can expand. If this is not observed, cracks may appear.

4. Is micro concrete waterproof?

Micro concrete is not waterproof by itself, but it can be if a sealant is used as a finish and the micro concrete is thus applied to washbasins, shower trays, bathtubs or wet areas. At Topciment we have created the Topsealer WT sealer (water-based polyurethane varnish), a sealer with which to guarantee the waterproofing of Micro concrete.

5. Is micro concrete slip-resistant?

Yes, depending on the type of micro concrete, texture left and sealant used, we can make micro concrete slip-resistant.

+information

Thanks to micro concrete we can achieve any non-slip surface. Depending on the type of micro concrete and texture, a greater or lesser slip resistance (degree of slipperiness) is obtained. From less to more slippery we have: Microstone for being highly textured, Microdeck with a smooth texture, and finally the Microfino which is not suitable for floors

The different finishes for floors and their textures
Floors are classified according to their slip resistance value, and from lower to higher resistance there are 3 classes, class 1, 2 and 3.
With Topciment micro concretes we can achieve any of the required classes. Microdeck sealed with polyurethane corresponds to class 1 but if you simply apply a coat of sealer and a coat of polyurethane, you can achieve class 2. If Microstone is used, which contains coarser aggregate particles than traditional micro concrete, class 3 is achieved. The difference in texture can be seen with the naked eye.
The anti-slip characteristics of the surface and the difficulty of cleaning must be taken into account. The greater the slip resistance, the more difficult it is to clean the surface due to the textured surface.
Here you can find out more about cleaning Micro concrete.

Non-slip finishes and classification according to slipperiness
In order to limit the risk of slipping, floors in buildings or areas for Public Residential, Health, Educational, Commercial, Administrative and Public Concurrence use, excluding areas of zero occupancy defined in annex SI A of the DB SI, shall have an appropriate class in accordance with point 3 of this section.
Floors are classified according to their slip resistance value Rd. This value is determined by the pendulum test described in Annex A of UNE-ENV 12633:2003. The Technical Building Code (CTE) in the document DB SUA-1 (Basic Documents for Safety in Use and Accessibility) regulates the slip resistance indexes and determines the class that a floor should have depending on its use. The floor becomes more slip-resistant as the Rd value increases.
Floors are classified, according to their Rd slip resistance value, as set out in this table: Floors are classified according to the following table

Slip Resistance (Rd) Class

Rd ≤ 15 0

15< Rd ≤35 1

35< Rd ≤45 2

Rd > 45 3

Class required for soils depending on their location and characteristics
The table indicates the class that soils must have, as a minimum, depending on their location.
This class shall be maintained during the useful life of the flooring
Dry indoor areas:
surfaces with a slope of less than 6% -> Class 1
surfaces with a slope equal to or greater than 6% -> Class 2
Wet indoor areas, such as entrances to buildings from the outside (1), covered terraces, changing rooms, bathrooms, toilets, kitchens, etc:
surfaces with a slope of less than 6% -> Class 2
surfaces with a slope equal to or greater than 6% -> Class 3
(1) Except in the case of direct access to restricted use areas.
Outdoor areas, swimming pools (2), showers -> Class 3
(2) In areas intended for barefoot users and at the bottom of pools, in areas where the depth does not exceed 1.50m.

6. What are the differences between micro concrete and polished concrete?

Although the aesthetic finish may be similar, they are not the same.
With micro concrete you get more advantages:

Faster and easier to apply.

No machinery or heavy tools are needed for installation.

Less work. Less cost. Less time.

Lighter, so no structural loads.

Use in any room, not just ground floors.

No joints required, and no cracks appear when dry.

It can be applied on both horizontal and vertical surfaces.

+information

Differences between Micro concrete and polished cement (trowelled concrete) for paving in terms of components

A distinction must be made between, cement, cement mortar, and concrete.cement is a component of both mortar and concrete that acts as a binder. Mortar is obtained by mixing sand and water with cement and concrete is a cement mortar to which gravel is added.

Although they are all solutions for creating pavements, in the case of micro concrete it is continuous and in the case of polished cement, printed concrete or trowelled concrete it is discontinuous (requiring expansion joints).

CONCRETE
Both polished concrete and printed concrete, as well as trowelled concrete, consist of a reinforced concrete slab with a surface treatment applied to achieve the final finish. They are discontinuous pavements, and as they are slabs, expansion joints are required to prevent cracking.

Trowelled concrete: In the case of trowelled concrete, mechanical smoothing is carried out with trowels or helicopters.

Printed concrete: While printed concrete is stamped with moulds. Both during the setting process (concrete hardening process).

Polished concrete: On the other hand, Polished concrete consists of applying a surface treatment to achieve the final finish but on the fully cured concrete. It consists of a mechanical process of grinding and polishing by means of which the surface is sanded with a polishing machine with diamond heads, leaving the section of the aggregates that make up the concrete visible, the final appearance is similar to terrazzo.

MICRO CONCRETE

Micro concrete is a coating that can be applied to both walls and floors, is approximately 2 to 3 mm thick, does not need joints and does not crack. It adheres very well to any material and is applied using a steel or rubber trowel.

MORTAR

The fattened mortar would be the smoothing that is done manually to a rendering (layer of mortar about 2 cm thick used to cover a wall)

15< Rd ≤35		1
35< Rd ≤45		2
Rd > 45		3

7. How long does a renovation with micro concrete last?

As micro concrete adheres to the existing material, there is no need for building work, so micro concrete work can be carried out in a very short time: between three and five days. On the other hand, the application of micro concrete on floors increases this period up to one week.

+information

This is a coating that is worked with a pre-conditioning of the surface, a application of the material in different layers, and a final protection with sealer.

Each layer of material has its own application and drying time. In addition, special care must be taken during the first week (once the work has been completed) as it gradually acquires its full hardness and resistance.

8. Do I need to brush the doors?

No, it is not necessary. The micro concrete will be built up on the surface to a thickness of 1 to 3 mm.
Normally the clearance between the doors and the floor is 5 mm, so there is enough clearance to avoid having to plane the doors.

9. How to clean micro concrete

One of the most frequently asked questions about this decorative coating is how to clean Micro concrete. Although the cleaning of micro concrete is simple and with water and neutral soap is more than enough, in Topciment we have created exclusive products for cleaning and care of micro concrete to obtain better results over time.

+information

The care of micro concrete is similar to that of natural wood parquet. It is advisable to avoid permanent waterlogging and prolonged contact with humidity. We must avoid leaving wet carpets and towels on the floor or pots that leak liquid. The surface should also be kept free of stones or grit, which can scratch the coating when stepped on. Avoid bumping and rubbing against hard objects.

Although micro concrete is highly resistant to chemical products, micro concrete should be cleaned with neutral soaps, never with aggressive products or descaling agents. Avoid products such as chlorine, bleach, ammonia, soaps and detergents in general, as they can damage the protective film.

Initial care

Micro concrete reaches the desired values of hardness, chemical resistance and waterproofing one month after application. The greatest risk of damage is in the first two weeks. It will be trafficable with great care two days after sealing of the pavements, and trafficable as normal one week later.

We recommend avoiding dragging heavy objects to avoid damaging the surface. To move furniture: it is better to lift and support, never drag. It is necessary to protect the floor from furniture (metal legs, sharp surfaces), and from objects with abrasive contact surfaces or of considerable weight, with covers or felts.

Permanent care

We recommend periodically maintaining micro concrete floors with Ceraciment or Ceraciment PRO or acrylic waxes. The frequency of waxing will depend on the use and characteristics of the location (traffic, surrounding dust, etc). We recommend the use of wiping mops to ensure correct application of the product.

10.can micro concrete lose colour over time?

In Topciment, micro concrete manufacturers , we have a wide range of micro concrete colours to cover any type of surface. However, can micro concrete lose colour over time? No, our micro concrete colours behave in a stable way, without suffering alterations over time and without being affected by the weather.

+information

The pigments we use to make our dyes are of mineral origin. Within the pigments we distinguish between those of mineral origin and those of organic origin. Pigments of mineral origin are the ones that behave best against the alkalinity of the cement. Organic pigments (molecules containing carbon) are not stable in the open air, they end up transforming into other compounds without pigmentary properties or migrating to the surface, so that some initial tones end up disappearing almost completely after some time. Inorganic pigments generally maintain stability in mortars and concretes.

11. Why might there be differences in brightness between the sample and the work being performed?

The application of micro concrete is a craft, factors such as the material load or the roller used in the sealing process mean that there may be small differences in gloss between the sample and the work. . The catalogues are sealed with a roller, if the sealing is done with a spray gun, a slightly higher gloss is achieved.

12. Can colours be combined on the same surface?

Yes, different colours of micro concrete can be combined on the same surface, even several finishes. The key is to clearly delimit the surface where you want to apply another colour.

13. Is it compulsory to apply the micro concrete mesh?

We always recommend applying fibre mesh, especially on tiled floors and walls, as well as in the joints between plasterboard panels, it is used to reinforce the micro concrete base and prevent cracks due to stresses in the micro concrete substrate. The final decision on whether to use it or not is up to the applicator, of course, but if they do not add it, warn them of the problems that may arise.

14. What drying time should we allow between the first coat of sealer and the second coat?

The drying time between coats of sealer or varnish will depend on several factors. For example, the weather conditions, the relative humidity, the ambient temperature of the room, whether it is an enclosed and humid space such as a bathroom, whether the sun has a direct impact on the room, etc.

In any case, we will always try in all circumstances to allow as much drying time as possible between coats to prevent white stains from forming because the surface is still damp. The minimum drying time between coats is 4 hours for Presealer and 24 hours for Topsealer.

15. How much does micro concrete cost per m2?

The price of micro concrete varies depending on many factors. Only a professional applicator of this decorative coating can give an accurate price per square metre of this coating.

The travel time of the professionals, the type of micro concrete selected and the substrate on which the micro concrete is to be applied are some of the factors that will determine the price per square metre of Micro concrete.

17. Can micro concrete be applied at low temperatures?

Micro concrete is a coating that tolerates low temperatures once in place thanks to the use of a protective varnish. However, care must be taken when applying this material in the winter season. In this sense, and to avoid possible whitish stains, fissures and cracks, it is necessary to heat the work area (20-25ºC) to obtain an optimum result.

18. Can micro concrete be applied in very hot weather?

Just as in winter, in the summer season a series of precautions must be taken if work is carried out with this material. Although it is a coating that resists perfectly, once applied, to the sun's rays. A resistance to UV light has expanded the bet of projects with micro concrete in outdoor spaces such as terraces and swimming pools.

In summer, avoid applying micro concrete in the central hours of the day and in the afternoon. Time slots in which the support is very hot and, if the material is placed, it could contract and expand the surface. During the rest of the day there is no problem.
