FREQUENTLY ASKED QUESTIONS

APPLICATION

Can microcement be applied outdoors?

Perfectly any of the CimentArt products can be applied outdoors, both on walls, ceilings and floors.

The exception is in pavements in areas with very low temperatures, in winter and especially where snow can be stored for several days (for example terraces that are outdoors and do not have any type of roof or cover) we do not recommend it for two reasons: the supports where the microcement is applied, with these temperature changes expand and contract a lot and can become fractured and this crack in the microcement can be noticed and the second reason is because it can be affected and even damage the final layer of polyurethane varnish protection, if it is under snow or water for several days.

Can microcement be applied on a kitchen worktop?

Of course, you can apply microcement on a kitchen worktop, the important thing is that the base, if you use wood or DMF as a support for the microcement, must be completely waterproof. Also, if you use more than 1 board (because the length of the worktop is too long) there will be a joint between them. This joint between the two boards must not have any movement between them.

You can also use marble, stone or granite or a worktop made of bricks and cement as a support.

Once the microcement cladding is finished on the worktop, the only precautions you should take are the same as you would on a wooden worktop: do not place a hot pot or pan on it and do not cut food with a knife directly on the microcement.

For more information, please send an email and attach photographs to contacto@grupocimentart.com and we will be happy to advise you.

What is the application system for microcement?

Microcement application system as it is not a single product but an application system. It is composed of a set of products that have to be applied in an order to obtain the best result.

The microcement application system consists of the following steps:

  • Bonding bridge.
  • Fibreglass mesh.
  • Microcement base: two coats (in some cases a third coat is necessary).
  • Fine microcement: two coats.
  • Sealer: one coat.
  • Two-component polyurethane: two coats.

In areas with direct contact with water, such as: showers, outdoor terraces, washbasins, kitchen or bathroom worktops, etc., an extra coat of sealant and bi-component polyurethane is recommended.

If you have any other queries, our technical department can assist you by contacting us.

Where can microcement be applied?

Where can microcement be applied? Microcement can be applied on any support or surface that is normally used in the construction of housing, whether indoors or outdoors.

Examples of absorbent supports where microcement can be applied:

  • Plaster
  • Putty
  • Cement plaster
  • Concrete
  • Plasterboard
  • Facade monolayer

Examples of non-absorbent or low-absorbent substrates where microcement can be applied:

  • Tile
  • Glazed stoneware
  • Earthenware ceramic
  • Porcelain stoneware
  • Wood
  • Paint

Is microcement suitable for any support?

Yes, however, it is thanks to the application of a coat of primer that is key to obtaining a good microcement job:

  • It leaves a more aesthetic finish
  • It is much more durable
  • It ensures and guarantees that it does not peel off from the substrate.
  • It facilitates the application

The bonding bridge helps the microcement to adhere more easily.

MAINTENANCE

Care and maintenance of microcement

Care of newly applied microcement

The possible danger of scratching and loss of shine of Microcement paving always occurs in the first few weeks. A pavement, already 100% hardened, has superior mechanical qualities that allow it to maintain an unbeatable appearance over time. Our cementitious paving requires around 4 weeks to achieve maximum hardness.

A newly finished microcement pavement should not be walked on for 3 days. It is vital to place protectors on the legs or supports of furniture, chairs or tables. Avoid dragging furniture or electrical appliances on a Microcement floor.

These floorings reach approximately half of their resistance in the first 48 hours. The cold, with temperatures below 10ºC, can paralyse or slow down the hardening process.

Care during the first 72 hours

Keep the temperature of the premises between 17ºC and 25ºC. It is not advisable to go above this temperature.

Do not walk on the floor or carry out any work in the treated rooms.

Completely avoid leaks, liquid spills and humidity during this period. Humidity and water bleach the polyurethane resins when it is not completely dry (polyurethane varnish needs 10 days to expel all its internal humidity and reach its maximum hardness).

Do not wash, wet, clean or attack the floor under any circumstances.

Do not protect the floor with cardboard or paper.

Care to be taken within 10 days of applying the last coat of bi-component polyurethane

Do not carry out painting, construction or similar works in the treated premises. If work is carried out, protect the floor completely with double cardboard and never use ladders without leg protections.

Clean only with water and without abrasive mechanical efforts or detergents of any kind. When cleaning, do not leave accumulated puddles of water.

Under no circumstances should paint, glue or liquids fall on the ladder, as they could amalgamate with our polyurethane and it would be almost impossible to clean them afterwards.

Avoid knocks or objects falling on the floor.

Use the floor with care.

Do not use acids or bases to clean the floor, only neutral detergents (similar to those used for marble or wooden floors) and rinse thoroughly.

Care after the first month

It is recommended to apply an acrylic wax every month to help protect the floor.

Always avoid contact with strong solvents, turpentine, hydrochloric acid or any type of acids or corrosive products.

In the case of loss of shine due to use on smooth floors, a cleaning and polishing operation can be carried out consisting of: energetic cleaning with specific descaling and rotary polishing machines (with a polishing sponge disc), rinsing and application of an acrylic wax.

In the case of kitchen worktops, do not place hot pots or pans on Microcement. Always place protectors on the legs or supports of furniture, chairs or tables. Completely avoid dragging furniture or electrical appliances on Microcement flooring.

Can Microcement be applied in swimming pools?

Although some swimming pools have been coated in the past, the application of microcement in a swimming pool is not recommended for two reasons:

  • Microcement is a coating and its purpose is to decorate, therefore it is not recommended to apply it inside a swimming pool and for it to be submerged under water for a long time.
  • Both changes in the pH of the water and the products used for water maintenance in swimming pools, whether freshwater (chlorine) or saltwater (bromine), are very corrosive and can affect the last layers of polyurethane varnish.

MATERIALS

How can I carry out a renovation without so much rubble?

Microcement is ideal for quick renovations, with practically no dust and no rubble, as one of its main characteristics is that it can be applied on any support.

Here are some examples:

If you want to renovate the walls of your kitchen or bathroom because the tiles are out of fashion, you can apply microcement on them without having to remove them and having to remove all the rubble.

Another example would be if you are tired of your old floor but do not dare to get into works, as normally the new floor is placed on top of the existing one and you have to remove all the skirting board of the house and cut all the doors of your home, with microcement you do not have that problem as it only has a thickness of 2 to 3 mm and you can even cover the existing skirting board.

Another very common use of the reform with microcement is in your kitchen countertop, changing it is very expensive, especially if you decide to place granite, Italian or Brazilian marble or a material such as Silestone or Corian. With microcement you can cover your old worktop without having to change it.

Another example would be the typical reform of removing the bathtub and build a shower tray, but do not want to reform the entire bathroom, just want to change that area of the shower. Microcement is perfect for this, and as there is a wide variety of colours, you will find the most similar tone or the one you like the most for just that area and you will not need to change all the bathroom tiles or the floor if you do not wish to do so.

Is there a more durable product than paint for walls?

Yes, we have a product called CimentArt Solid Colour for it.

A CimentArt microcement wall is for life. When a wall is painted with paint usually every two to five years at the most you have to repaint it because it is chipped dirty or worn.

The Microcement CimentArt is a completely waterproof product which allows you to even scrub the walls with a scouring pad and soap and have the walls always like the first day.

Of course, we know that the paint is a cheaper product than the microcement but it is not eternal and unlike the microcement will give you a much more durable result in time and without any maintenance.

If you do not like the effect of stains or marbling of traditional microcement on the wall use CimentArt Solid Colour, which is a coating without any kind of stain and with a completely uniform colour like paint, but which, as we have said before, you can clean it whenever you want with any chemical product normally used in a house and has no maintenance so it is a product for life.

What type of microcement finish can I use in my home?

CimentArt, with its extensive range of products, offers different finishes so that any customer can choose depending on the housing and personal tastes a personalized finish and colour according to their preferences.

If you want a completely smooth finish and marble effects choose the microcement cimentart. There are 35 different colours available.

If you want a more rustic effect or more similar to a cement that does not have such a fine finish, choose Cimentart Rustic. We also have 35 colours in this product so that you can choose the most suitable for you.

If you prefer a cementitious finish but with less stains or marbling than the traditional microcement you can choose Cimentart Nature, also available in 35 colours.

If, on the other hand, you would like to have a covering that imitates a natural stone without joints, your product is Cimentart Stone. This product is also available in 35 colours.

If you do not like stains or marbling and prefer a completely smooth and uniform colour you can opt for Solid Colour CimentArt. This product is available in more than 1000 colours.

If you want to have a completely different wall or floor, we have highly decorative effects such as natural rust or 12 different metallic colours.

If you are not a professional and still would like to apply microcement in your home we have Microcement ready to use, where you do not have to do any mixing and are very easy to apply. The name of this product is iCem Quartz CimentArt and with this product you can make very aesthetic applications with effects and ‘stains’ similar to traditional microcement and is available in 12 colours.

In the ready to use range we also have iCem Mirohormigon, a finish with less stains or marbling than iCem Quartz, also available in 12 colours.

All our products can be finished with a gloss, matt or satin finish, both indoors and outdoors.

We are at your disposal to advise you on which product(s) and colour(s) are best suited to your home. Contact your microcement experts.

Differences between microcement and Venetian stucco

Microcement and Venetian stucco are products that have their similarities when seen from a distance, but they are really very different from each other.

Venetian stucco is a product made from putty (calcium carbonate) and is mixed with water. Due to the hardness of this material, it is only applied on walls, it can never be applied on floors. Venetian stucco is not a suitable product to be applied in kitchens, bathrooms, showers or outdoors, because it is not waterproof.

Microcement is a product that due to its hardness (it is composed of cement and selected minerals mixed with resin, not water) can be applied both on walls and floors and in areas that receive water such as bathrooms, kitchens and outdoor terraces. This means that they are very different products and cannot be compared.

What is microcement?

Microcement is a highly decorative coating, with very little thickness and which can be applied on walls, floors and ceilings, both indoors and outdoors.

Due to its application method, its final finish is always smooth, continuous, without joints and its final result resembles a smooth or polished cement with certain nuances similar to some marbles.

Its formulation is a mixture of special cements, selected minerals, acrylic resins, pigments and other components to obtain more resistance and impermeability.

What is needed when applying microcement?

A microcement reform, not many things are necessary.

Necessary materials:

Bonding bridge – Fibreglass mesh – Microcement Base – Microcement Fine – Mixing resin – Sealant – Polyurethane (Matt, Satin and Gloss).

Tools required:

Masking tape – Sandpaper from 40 to 60 (for microcement base) – Sandpaper from 140 to 200 (for fine microcement) – Sanding machine – Blender – Steel plane – Spatula – Short-haired rollers – Vacuum cleaner.

What does microcement mean?

Microcement is not a single product, but a type of finish. It is a decorative coating without joints, applicable on any surface and waterproof.

As for the field of application, it is very large, because of its waterproof performance, hardness, non-cracking, etc., and its minimum thickness, it can be applied on any surface (floor, walls, shower trays, countertops …) and support (terrazzo, marble, plaster, cement, wood, tile, etc.) both indoors and outdoors.

Learn how to apply microcement

Nowadays there is a large number of specialised professional applicators, so specialists with the necessary training will have a large market.

To get qualified professionals in the application of Microcement, Due to the existing demand in the current market and the pace of growth, CimentArt Group performs free and professional courses, regularly at its facilities in El Campello (Alicante) and in our various delegations.

SURFACES

Can microcement be applied on underfloor heating?

Yes, perfectly microcement can be applied on floors with underfloor heating.

In fact it is one of the best coatings that can be placed on a floor with underfloor heating, as having a maximum thickness of 3 mm, it is perfect for the floor does not lose heating power.

A tile, parquet or floating floor can be more than 1 cm thick and obviously radiant heating requires much more time and much more energy consumption to reach the desired temperature.

Once the installation of pipes for radiant heating is done, it is usually covered with a layer of at least 4 cm of cement mortar, a self-levelling mortar or a dry mortar.

Before pouring these mortars, it is necessary to place a perimeter expansion joint (5 to 8 mm) in all the walls and door frames of the house, so that these mortars do not come into contact with the wall. The reason for this perimeter expansion joint is because when the radiant heating is turned on, the floor expands (almost 1 mm per m2). If this joint is missing, the flooring will certainly split.

It is also recommended to make a thin expansion joint under each door or in critical areas such as where the corridors meet the rooms to prevent the floor from splitting in these areas.

Finally, before starting the application of microcement, the radiant heating should be turned on and allowed to reach its maximum temperature for several hours and then turned off again. This operation must be done for two or three days to see how the radiant floor behaves before the application of microcement.

Can microcement be applied on a staircase?

Yes, microcement is the perfect material for covering and/or renovating a staircase.

Stairs are one of the most problematic elements to renovate in a house as removing all the old steps is a very laborious job and if it is covered with another ceramic material, marble or wood, there will always be a small and uncomfortable “step” on the top floor with respect to the floor of the mezzanine.

Likewise, if it has any type of wooden or metal railing, this makes it very difficult to cover it, whether the old covering is removed or not.

As microcement has a maximum thickness of 2 to 3 millimetres, it is perfect for covering staircases, and the meeting point that remains on the mezzanine floor, as it is so thin it is practically imperceptible when walking on it.

Substrates such as old granite or marble are perfect substrates for applying microcement, as they are very hard and have a corner that will not deform or break over time.

If the application is made in a new building, we recommend always placing hidden metal corner pieces for greater durability and to prevent the corners of the base where the microcement has been applied from breaking over time (normally the stair treads of this type of stairs in new buildings are made with bricks and plastered with cement mortar or are concrete steps plastered with cement mortar). In these cases, it is always recommended to place these corner pieces hidden in order to achieve a better finish and durability of the corner of the stair tread.

In all cases we recommend that the edge of the step should never be at a 90° angle and that these edges should be slightly rounded.

Can microcement be applied in industrial buildings or parking lots?

Microcement is a highly decorative coating. Its purpose is to create a continuous seamless coating and to decorate at the same time.

Each material has its precise use and just as nobody would place asphalt on the floor of their bathroom, we do not recommend the application of microcement in industrial buildings, car parks, shopping centres, roads, etc., as these are areas with heavy traffic of cars, heavy machinery and where pallets are moved that can hit and scratch the microcement.

For these areas there are special materials for this purpose, such as epoxy, polished cement, asphalt, etc.

Microcement is perfect for the interior of homes, shops, offices, etc.

For more information you can contact your experts in microcement.

Can microcement be applied on substrates with capillary humidity?

Do you have capillary humidity and want to apply microcement?

Tienes humedad capilar? El microcemento no se debe aplicar nunca en soportes que tengan humedad capilar, ya que esta terminado con un barniz de poliuretano que lo hace impermeable, pero también no transpirable.

Si el microcemento es aplicado sobre soportes de cemento o yeso que tienen este problema, pueden salir manchas más oscuras debido a esa humedad ascendente y con el tiempo que se deteriore el microcemento.

Si aplica microcemento sobre paredes revestidas con azulejos o en pavimentos con baldosas cerámicas que tienen humedad capilar, con el tiempo pueden marcarse las juntas en dichos azulejos o baldosas.

Nuestro consejo si desea hacer una aplicación de microcemento CimentArt y tiene este problema en el suelo o en las paredes es que aplique previamente CimentArt Dry con un espesor mínimo de medio centímetro. CimentArt Dry es un mortero impermeabilizante que es usado para cortar la humedad capilar y también para el enlucido de depósitos de agua o jardineras. Después de la aplicación de Cimentart Dry puede comenzar la aplicación del microcemento y esa humedad por capilaridad no traspasa.

Sabemos de algunos casos de algunos aplicadores que sobre pavimentos con baldosas que tenían humedad capilar, primero taparon o rellenaron bien todas las juntas entre baldosas y después aplicaron dos capas de epoxi de dos componentes y eso ayudo a parar la humedad ascendente y una vez completamente secas estas capas, aplicaron nuestro microcemento siguiendo nuestros métodos de trabajo con buenos resultados.

State of the supports where the microcement is applied

The support where you are going to apply microcement, whether absorbent or non-absorbent, whether in a new construction or renovation, must be in perfect condition, dry, with hardness, without movement or expansion and without parts that are detached or deteriorated.

On a cement plaster, concrete or plaster must have passed at least three weeks before the application of microcement, so that the support has set and completely expelled its internal moisture.

If you are going to apply microcement on ceramic tiles, they must be completely glued. If they sound hollow when touched, they should be removed and the microcement applied on the substrate below. If any tile is poorly placed this must be removed and filled with cement mortar.

If you are going to apply the microcement on paint it must be perfect in perfect condition, without chipping or parts that are easily removed.

If where you are going to apply the microcement there is capillary humidity, this has to be previously treated with the waterproofing mortar CimentArt Dry. For more information on this product see here.

TECHNIQUES

Can I apply microcement or does it have to be done by a professional?

Microcement is not a complicated product to apply but it is a system of several layers and this is a fairly precise process when doing so.

Therefore, we recommend that the application is always performed by a professional who has done training courses Microcement with us to ensure that your Microcement will be properly applied and will be to your satisfaction.

Click on this link to find your nearest professional applicator cimentart.

CimentArt Microcement conducts training courses every week at its facilities for any individual or professional who wants to learn their application techniques. For more information on our training courses click on this link.

We also have a ready-to-use microcement called iCem CimentArt, which is much easier to apply than traditional microcement, as it does not need special tools or need to make any kind of mix, it is already prepared and ready for use.

iCem CimentArt is a perfect product for adventurous people who dare and want to do themselves the application, even if they are not professionals in the sector.

The microcement is slip resistant or slippery?

Microcement is always finished with a protective layer called polyurethane varnish.  There are two different types of polyurethane varnish on the market: water-based and solvent-based.

Cimentart only uses water-based polyurethane varnish in its systems, for different reasons:

  • It slips much less if it is wet or has water than solvent-based polyurethane.
  • It leaves more layer (it has more thickness than the solvent-based polyurethane) and therefore has more covering and protection power.
  • It does not release vapours and gases so annoying and harmful to the environment and to the applicator and the end customer.
  • It is easier to transport since it is not a flammable material, solvent-based polyurethane is.

Currently the most commonly sold materials for example for shower areas are porcelain showers or enamelled bathtubs. These are very smooth materials that are very slippery and need some kind of plastic anti-slip “mat” or similar materials.

The bi-component water-based polyurethane that CimentArt uses for the finishing of its pavements is much less slippery than any shower or bathtub that is currently sold in the market.

However, we have Anti-Slip Microspheres. This product is a very fine mineral and crystal powder that added to the CimentArt polyurethane varnish creates anti-slip floors and with it you will get a C3 certificate, which is the maximum in the certificate of slipperiness.

Cimentart Microcement puts at your disposal for those who request this certificate by contacting us.

Microcement components

The components of microcement CimentArt are as follows:

  • Bonding bridge: ensures adhesion of microcement on the support where it will be applied.
  • Fiberglass mesh: ensures a good reinforcement of the entire Microcement and helps to prevent cracking of the product. On surfaces with low absorption as paint, stoneware floors and tile walls facilitate the application of the first layer of Microcement cimentart base.
  • Microcement base: used for the regularization of supports and plugging of joints in floors and tiles and as preparation for the subsequent application of fine Microcement.
  • Microcement fine: used to achieve a completely smooth finish and its application will achieve the decorative marbled effects so characteristic of Microcement.
  • Mixing resin: is the resin used to mix all microcement cimentart. With this resin will achieve greater hardness and greater flexibility in any microcement. Our Microcements are white or cream. Mixing resin incorporates the desired colour and with it we get to make our extensive colour chart.
  • Sealer: with our sealer will get completely close the pore on the microcement, creates the first waterproofing on it, enhances the final colour of the microcement and helps the subsequent application of the last product is the protective varnish (bi-component polyurethane).
  • Bi-component polyurethane: is the final protector. With its application will get the Microcement coatings are completely waterproof. It is also responsible for the Microcement can use any cleaning product normally used in a home and finally this product is responsible for the final finish that the customer has chosen: gloss, satin or matte.

For more information you can contact your experts in Microcement

Temperatures for applying microcement

CimentArt microcement and its entire system should be applied at temperatures from a minimum of 5° to a maximum of 30°.

Lower or higher temperatures will result in a very costly application and incorrect drying of the products and both its final result and its durability will not be adequate.

It is also not recommended to apply the microcement system with strong direct sunlight or strong air currents, as this will accelerate its drying time too much and hinder its application.

The characteristics of microcement

Characteristics of microcement:

  • It is a continuous decorative coating without joints.
  • It has a very aesthetic finish, similar to a polished cement,
  • It has a maximum thickness of 2 to 3 millimetres.
  • Great flexibility and hardness.
  • It can be applied on any existing support.
  • Wide range of colours to choose from.
  • Three different finishes to choose from: gloss, satin and matte.
  • Can be applied in wet areas such as showers, bathrooms, sinks, kitchen and bathroom countertops, etc.
  • Can be applied on walls, ceilings and floors.
  • It can be applied both indoors and outdoors.
  • It has a completely waterproof finish.
  • Any cleaning product normally used in a house can be used.
  • It has no maintenance.

Does microcement crack?

Does microcement crack? Because of its composition, it never cracks by itself in any case.

If any crack appears on the microcement is because the support where it has been applied to cracked and this crack is usually half a millimetre thick minimum.

Small micro cracks that may appear in a plaster or cement plaster CimentArt Microcement perfectly supports them and are not visible.

It is therefore very important that the support where the microcement is applied is strong and healthy, do not have peeling or crumbling parts, poorly placed tiles or paint in poor condition, as this can give a false appearance that the microcement cracks, when it is not so in any case and it is always the support that cracks.

A strong support and proper preparation are key to a durable microcement. Contact our technical department.
