Why bet on microcement for exteriors

There are many reasons why it is a great idea to choose microcement for exteriors, whether as a wall, facade, porch coating or as a continuous outdoor pavement, the latter being the preferred option of experts.

Be that as it may, applying microcement outdoors guarantees the creation of incredible environments, as it forms a coating whose magnificent adherence allows its application on the most diverse supports and materials. A continuous decorative coating that combines a powerful aesthetic visually on one hand, and, on the other, functionality in capital letters.

Next, we develop the six main advantages that have popularized microcement in exteriors:

1. The microcement for exterior provides continuity

Microcement is a continuous coating that is applied directly to the existing support. That is, it does not require expansion joints. A great added value that allows outdoor microcement to blend perfectly with the rest of the architectural and decorative elements, providing that sense of continuity and harmony among all components. A continuity that can go a step further and serve the outdoor microcement as a link with the interior space of the house or premises.

2. The microcement outdoors is very resistant to traffic

The high performance of microcement remains intact outdoors. This is the case of its resistance to traffic, the main factor that has led to the microcement outdoors gaining renown as an alternative to other coatings such as natural or artificial stone, tiles, concrete or gresite, among many others.

3. Rain and heat do not affect microcement outdoors

Weather conditions are decisive in the choice by architects, decorators and other construction professionals of the materials to be used outdoors. The microcement, if a quality one is used and it is protected and sealed with the appropriate varnishes, will not be affected by rain and heat.

4. The microcement outdoors has antiseptic properties

Thanks to its continuity, the microcement in exterior prevents the growth of fungi, weeds or bacteria, thus obtaining an antiseptic space. In addition, it is a very easy to clean decorative coating that requires minimal maintenance and care.

5. The exterior microcement floor is non-slip

Pursuing materials that provide a non-slip finish on exterior coatings is non-negotiable. Therefore, you will be pleased to know that there are types of microcements (like Sttandard Microstone, our microcement for exteriors) that have this capability and will turn the continuous exterior microcement pavement into a completely slip-free space.

Another of the non-slip microcements for outdoors is Atlanttic, our specific two-component microcement for swimming pools. In fact, at Topciment we also have Topsealer WT Anti Slip, our water-based polyurethane varnish that turns exterior surfaces coated with microcement into non-slip surfaces.

6. The microcement for exterior is very durable

Lastly, and not least importantly, if there is a peculiarity that perfectly defines exterior microcement, it is its durability. It is a flooring or wall covering capable of maintaining its performance in optimal conditions despite the passage of time.

In this way, with microcement in exteriors, not only is a high decoration, elegant and sophisticated finish achieved; but also a very durable coating over time, almost everlasting.

Ideas for using microcement outdoors

Microcement can be perfectly used in multiple ways in outdoor spaces. Below we give you some of the best ideas to use microcement for outdoors thanks to its limitless customization of finishes and colors. Take note!

Microcement for outdoor terraces

Microcement floors are the most common use for outdoor microcement, especially on terraces. Since it is a coating capable of covering large areas like terraces in one piece, thus avoiding the accumulation of dirt. But above all for the beauty of its finishes and the wonderful resistance to water and environmental humidity that outdoor microcement presents.

Microcement for exterior in facades

Walls and facades coated with microcement offer the same benefits as pavements. And if it is also combined with an exterior microcement floor, the feeling of spaciousness will multiply exponentially. The wide customization allows obtaining from more minimalist and industrial finishes, to more rough or rustic ones.

Microcement for outdoor use in swimming pools

When building a pool, people usually resort to concrete pools. With microcement pools, you can achieve the same spectacular result with the added advantage of not having to carry out costly works. A time saving directly proportional to the saving also of labor cost.

Not to mention that the exterior microcement for pools adapts perfectly to any type of space, even if your terrace is small or has complicated unevenness.

How much does the microcement cost outdoors?

It may give the impression that the microcement priceoutdoors is higher than indoors. However, this perception is completely wrong. The final cost of applying microcement for exterior and interior depends on the same factors: state of the support (if it has humidity, if it is not stable, if it needs to be fixed, etc), the surface in square meters that needs to be covered and the difficulty of the work itself.

Only on one occasion is the price of microcement in exterior higher: in the case of pools. Why? Because its application is much more complex and requires more expensive labor.

How to correctly apply microcement outdoors

To apply microcement outdoors without problems, a series of steps must be strictly followed. Making mistakes in the process would result in a very different final finish than desired and expected. Hence, it is so important to have a trained and experienced professional.

These are the six steps to apply microcement outdoors:

1. Condition the support that is going to be coated with the outdoor microcement. Check that it is in good condition and, if not, repair it.

2. Place the fiberglass mesh on the future exterior microcement floor or wall, which will help reinforce the future continuous decorative exterior coating.

3. Prime the future exterior microcement coating with an adhesion promoter.

4. Apply two coats of outdoor microcement base.

5. Apply two coats of finishing microcement for outdoors.

6. Seal the coating of exterior microcement with a good varnish.

Process of applying a microcement floor outdoors

The application of an exterior microcement floor is always the same. The only thing to choose is the type of microcement we want (we recommend Sttandard Microstone), and the color.

En este caso la aplicación de un suelo de microcemento en exterior con Sttandard Microstone sería el siguiente:

  1. Fiberglass mesh and primer on the future exterior microcement floor.
  2. A layer of unpigmented Sttandard Microbase microcement.
  3. Apply two coats of Sttandard Microstone, our finishing microcement for outdoor floors, which are already pigmented.
  4. Seal and protect the exterior microcement floor. First with two layers of our water-based acrylic varnish Presealer, then with another two coats of any of our polyurethane varnishes from the Topsealer family.

Process of applying exterior microcement on walls

The application of exterior microcement on walls changes compared to that of . Instead of using Sttandard Microstone as a finishing microcement, which can also be done, we are going to focus on the case of using any of the Microfino microcements: Sttandard Microfino (two-component), Evoluttion Microfino (one-component) or Efectto Quartz Small Grain (ready to use).

In addition, unlike exterior microcement floors where a single layer of base microcement was used, applying exterior microcement on walls will require a double layer.

Process of applying exterior microcement in swimming pools

The anti-slip and waterproof nature of microcement pools, as well as their resistance to the effects of the sun, make it one of the smartest uses that can be given to outdoor microcement. As previously mentioned, its application is somewhat more complex.

Atlanttic, our exterior microcement system for swimming pools is applied in the following way:

  1. Before applying the exterior microcement for swimming pools, a layer of resin will be necessary. We have developed Acricem.
  2. Two layers of Atlanttic Aquaciment XL base microcement, the first one without pigment and the second one already pigmented.
  3. Two layers of Atlanttic Aquaciment M, our finishing microcement for swimming pools.
  4. Finally, seal the exterior microcement in swimming pools with two coats of Presealer, which will waterproof the support.

Sttandard Microstone, the most resistant microcement for exterior

It has been demonstrated that there is a wide range of microcements that can be applied in outdoor areas. The final choice for one or another will be based, mainly, on the finish that is sought.

At Topciment, all the microcements we manufacture are high performance. Products that meet the needs of floors or facades exposed to weather changes, among other factors. Therefore, whatever coating is selected, it will definitely meet the intrinsic needs when applied in outdoor areas.

Even so, we insist again on Sttandard Microstone ,specially designed to be used as outdoor microcement and, therefore, with superior resistances. And it is that Microstone offers a magnificent resistance to abrasion, traffic and temperature changes. A robust microcement, with anti-slip finish and whose appearance resembles natural stone.

As you have been able to verify, the microcement in exteriors gives a lot of play. All kinds of structures and environments can be created depending on where it is applied. So now that you know everything you need to know about outdoor microcement, what are you waiting for to start remodeling your space?
