The drawbacks of microcement and their solutions
Microcement is growing in popularity, but like any successful product, it has its detractors. Are the drawbacks of microcement in bathrooms well-founded? Its advantages—such as its smooth, seamless finish and its ability to adapt to any type of surface—make it a popular choice for floors, walls, and even showers. So what’s the issue? Should you listen to the critics?
It’s legitimate to wonder whether microcement is truly a safe option for your bathroom. In this article, we’ll go over the most common concerns related to the drawbacks of microcement for bathrooms, putting them into context.
Whatever your microcement project may be, this article will provide you with the essential information to make an informed decision. And if you already know you want to do it yourself, our bathroom microcement kit takes care of most of the points below as standard: primer according to the substrate, two coats of microcement and the varnish that protects it.
1. Demanding maintenance: a necessary evil?
Microcement is a material that combines aesthetics and modernity, but like any high-quality finish, it requires specific care to preserve its shine. Unlike more common materials, microcement can be vulnerable to stains and wear if unsuitable cleaning products are used. Using harsh detergents or acidic products can damage the surface finish, leaving unwanted marks and reducing the lifespan of the coating.
Solution and experience
There is a range of products specially designed to maintain microcement. Formulated to clean deeply without damaging the surface, these products help preserve the coating’s aesthetic appearance over the long term.
In reality, regular microcement maintenance is simple and holds no mystery. A soft cloth and a neutral cleaner are enough to remove dirt and keep the surface spotless. Unlike other materials that require complex treatments or frequent renovations, microcement offers a durable, practical solution for those looking for an aesthetic finish with minimal upkeep.
So while microcement maintenance may seem demanding at first, it quickly becomes an easy routine to adopt. Minimal regular care with a mild soap or our Smart Cleaner lets you fully enjoy this modern, elegant material, while ensuring its longevity in your bathroom.
2. Risk of cracks: how to prevent them?
Although microcement is appreciated for its modern look, it does have potential drawbacks, such as the risk of cracking. These cracks can appear due to temperature variations—especially in a bathroom where humidity is omnipresent and thermal changes are frequent. Moisture, combined with heating and cooling cycles, can cause the material to expand and contract. This movement could lead to cracks that affect not only the appearance but also the structural integrity of the coating if the installation process is not properly followed.
How to prevent microcement cracks?
To prevent cracking, the key lies in meticulous substrate preparation before applying microcement. The surface must be stable, free of pre-existing cracks, and able to withstand stress without deforming. This involves carefully filling existing cracks and applying a bonding primer to ensure optimal adhesion of the microcement.
The quality of the products used also plays a role in the coating’s durability. Choosing high-quality materials specifically designed to withstand humidity and temperature fluctuations ensures microcement’s resistance. These products are often formulated to increase the coating’s flexibility, allowing it to absorb stress without cracking.
In short, while the risk of cracking is something to consider, proper substrate preparation, the use of quality materials, and a methodical application reduce this risk enormously: with a sound substrate, thin coats and the drying times respected, cracks have no reason to appear.
3. Slippery surface: a controlled risk
Although very aesthetic and modern, microcement has a drawback for some when used in a bathroom: it can become slippery when wet. This concern is legitimate in damp areas, such as showers and around bathtubs, where the risk of slipping already exists. At Smartcret, we address the risk of slipping linked to microcement’s smooth texture—something also common with tile or linoleum floors, in particular.
How to reduce the risk of slipping on a microcement floor
There are several ways to make microcement safer without compromising its sleek aesthetics.
It is worth knowing what the finish contributes: on the bathroom floor, our floor kit uses Smart Medio, a medium-grain microcement that gives more texture and hardness than the smooth one, and the varnish is applied in a matt finish; neither of the two is non-slip. If you want to know more, read how to apply microcement on the bathroom floor.
Another simple but effective solution is to use bath mats or anti-slip grates in risk areas. These mats, which fit easily into bathroom décor, provide additional protection by creating a barrier between wet feet and a potentially slippery floor. Available in a variety of styles and materials, they allow you to combine safety and aesthetics, matching your bathroom textiles.
By combining these solutions, you can enjoy the aesthetic benefits of microcement while minimising the risk of slipping. With proper planning and preparation, microcement can be used in the bathroom with these precautions and provides both style and peace of mind.
4. Humidity and mould: a matter of preparation
Humidity is one of microcement’s main enemies, especially in an environment like the bathroom. If preparation and application are not carried out correctly, water infiltration can occur, leading to mould and deterioration. These issues affect not only aesthetics but also the durability of the finish. Corners, edges, and areas near water points are particularly vulnerable to these risks.
How can you prevent humidity and mould?
The key to avoiding these problems lies in properly preparing the compatible substrate before applying microcement. It must be smooth, clean, and dry. Make sure to seal all cracks and irregularities before you begin. Then, applying a suitable bonding primer helps ensure optimal adhesion of the microcement.
Once the microcement is applied, protection is provided by using an appropriate protective varnish. This varnish makes the coating waterproof and prevents water from penetrating and causing damage. In areas especially exposed to water, such as showers or floors around bathtubs, apply every coat of varnish the instructions specify (three, with Smart Booster), without skipping any.
These precautions effectively ensure your microcement’s resistance to the challenges of humidity, while preserving its elegant, modern appearance. Careful preparation and the use of high-quality protective products guarantee both a long-lasting installation and peace of mind against water- and mould-related risks.
5. High cost: a long-term investment
The cost of microcement is often seen as a major obstacle to adoption. The price per square metre of microcement can rise significantly for high-end finishes and, above all, if professionals are hired for application. This budget can discourage some décor enthusiasts, especially compared to other standard covering solutions that may appear more affordable.
Our view
Microcement is a long-term investment rather than a simple expense. Its durability is one of its greatest advantages. Unlike other finishes that require frequent replacement or costly repairs, well-maintained microcement can last for decades without losing its shine or functionality. This longevity alone more than offsets its initial cost.
In addition, microcement requires little maintenance. Simple regular cleaning with gentle products is enough to preserve its original appearance. The absence of joints—often the first areas to show wear in other coverings—also reduces hassle and maintenance costs. The protective treatments applied during installation further extend the material’s durability, limiting future interventions.
Finally, microcement is an aesthetic choice that adds value to your property. Its modern, elegant look appeals to many potential buyers, which can translate into a return on investment when selling.
So while microcement may represent a significant initial investment, its advantages in terms of durability, maintenance, and property value make it a cost-effective, long-lasting solution for your bathroom.
6. Application complexity: should you hire a professional?
Applying microcement, while appealing for its final result, can seem complex. Depending on the project—such as installing a microcement bathtub—application may require specific expertise to ensure a successful aesthetic and long-term durability. Surface preparation, mixing components, even application, and finishing steps require, for these complex projects, a technical mastery that few DIYers have.
A matter of method
First of all, application complexity only applies in rare exceptions. Microcement application is, by definition, simple in most cases.
Likewise, to avoid complications and ensure a result that meets your expectations, we invite you to use products suited to your project and your level of experience. Smartcret products are perfectly suited for most projects that a beginner DIYer would want to take on.
Even the most daunting projects, such as the microcement sink, have their step-by-step guide and are covered by the bathroom kit. The real exception is the bathtub: microcement is not designed to hold water permanently, so it falls outside the DIY kits and, if you are considering one, it is best left to an experienced applicator.
In short, while applying microcement may seem complex, professional expertise is unnecessary for 90% of projects thanks to Smartcret’s all-in-one solutions and microcement kits.
The kit brings them all, with the 40, 220 and 400 grit sanding discs and the instructions; the tools (trowel, roller and tray) are sold separately, in the Smart Tools tool kit.
7. Sensitive to chemicals: precautions to keep in mind
Despite its many aesthetic and practical benefits, microcement—like many other finishes—is sensitive to harsh chemical products. As we saw in the maintenance section, strong detergents or cleaners are unnecessary.
Neutral pH solutions
Cleaning and maintenance with a mild soap are enough. If you wish, you can use neutral pH solutions specially formulated for microcement. These clean effectively without damaging the surface and preserve the finish and colour of the coating.
In addition, applying a surface treatment, such as Smartcret’s Smart Varnish, offers extra protection against chemicals. This treatment acts as a barrier between the microcement and potentially aggressive substances, making cleaning easier and extending the lifespan of the finish.
In conclusion, while microcement is sensitive to chemicals, proper care with gentle products and appropriate protection make it possible to maintain its durability and aesthetics.
8. Specific thickness and application: adapted to each surface
Microcement is a versatile material that can be applied on various surfaces, such as walls, floors, or even showers. However, to ensure an optimal result, you must follow the thickness specifications depending on the application and the product.
In general, microcement is applied at a thickness of about 2 to 3 mm. On a wall, a thickness that’s too great is unnecessary, while on a floor, an insufficient thickness could reduce resistance to impacts and wear.
Let yourself be guided: nothing could be simpler
Smartcret offers kits adapted to different surfaces—floors or walls. These all-in-one kits come with clear instructions that specify the optimal thickness and the application steps, helping you avoid mistakes. Following these instructions and choosing quality products allows you to maximise microcement longevity. You’re guided step by step to achieve a flawless finish on any surface in DIY mode.
9. Variable aesthetics: a result to control
One of microcement’s appeals lies in its unique, personalised look, which varies depending on the application technique, composition, and colour. However, this versatility can also be a challenge, since the final result may sometimes differ from initial expectations. Variations in colour, texture, or finish can appear if the application lacks precision, leading to a less uniform result than desired.
It all comes down to preparation
To ensure a consistent and aesthetically pleasing result, following the application guide included with Smartcret microcement kits is your best guarantee. It guides you through each step.
- Get informed
- Choose the finish
- Prepare the substrate
- Test
