7 Surprising Facts: Is Microcement Porous or Not?

When it comes to innovative interior and exterior surface finishes, microcement is having its moment. With its sleek, continuous finish and ability to transform any surface—from floors and walls to bathrooms and pools—this material has taken Malta’s design scene by storm. But one common question still lingers in the minds of homeowners and professionals alike: is microcement porous?

In this comprehensive guide, we’ll break down exactly what porosity means in this context, why it matters, and what you should expect when installing microcement in your Malta property. Spoiler alert: no, it’s not porous—but the reasons why are worth exploring in more depth.

1. Understanding Porosity: Why It Matters in Surface Materials| Is Microcement Porous

Before diving into microcement specifically, let’s quickly define porosity. In construction and interior design, porosity refers to a material’s ability to absorb water or other liquids. High porosity can lead to issues like:

• Water damage

• Mold and mildew buildup

• Stains and discoloration

• Surface erosion over time

This is especially important in humid environments like bathrooms or outdoor terraces in Malta, where rain, humidity, and temperature shifts can be extreme.

Materials such as natural stone or untreated concrete are highly porous, meaning they require regular sealing and maintenance. So, when clients ask, “is microcement porous?”, they’re usually concerned about long-term durability and upkeep—especially in moisture-prone areas.

2. Is Microcement Porous? The Definitive Answer| Is Microcement Porous

Let’s clear this up right away: No, microcement is not porous—at least, not when installed correctly.

Here’s why:

• Sealing System: Microcement systems include a multi-layered sealing process that makes the surface fully waterproof and non-absorbent.

• Polyurethane Finish: The final layer typically includes polyurethane sealers that create a protective, impermeable film.

• Cohesive Application: Because microcement is applied in continuous layers without joints, it leaves no room for water to seep in between gaps.

So while the base microcement material may have slight porosity in its raw form, the complete system used in professional installations ensures that the end result is completely sealed and water-resistant.

This is why microcement is a fantastic solution for bathrooms, kitchen counters, wet rooms, and even pools. You get the raw, minimal aesthetic of concrete—but none of the porosity issues.

The versatility of microcement is what makes it such a fast-growing trend in the Maltese construction and interior design industries.

Microcement has rapidly become a favorite surface finish for homeowners, designers, and architects across Malta. Its seamless finish, sleek look, and durability have made it a modern solution for both residential and commercial spaces. Yet, one of the most frequently asked questions remains: is microcement porous?

The short answer is no, microcement is not porous—when applied correctly. But let’s go deeper. In this comprehensive guide, we’ll uncover everything you need to know about microcement’s permeability, its resistance to moisture, how it compares to other materials, and what you can expect in a real-world application. If you’re considering this material for your floors, walls, or outdoor areas, this blog is for you.

1. What Does “Porous” Really Mean? | Is Microcement Porous

Before diving into whether or not microcement is porous, let’s first understand what porosity means. A porous material contains tiny holes or pores that can absorb water, air, or other substances. This is especially important when it comes to materials used in wet areas like bathrooms, kitchens, or outdoor patios in Malta’s humid Mediterranean climate.

Materials like untreated wood, concrete, or natural stone are naturally porous, making them vulnerable to moisture damage unless properly sealed. With microcement, however, the situation is very different.

2. Is Microcement Porous? | Is Microcement Porous

Here’s the truth: microcement is not porous when installed and sealed correctly. The key lies in the multi-layer application process, which includes:

• A primer that ensures adhesion to the base layer

• Several layers of microcement

• A protective sealer that locks everything in and makes the surface water-resistant and stain-resistant

This final sealer layer is what makes all the difference. It creates a barrier that protects the surface from absorbing moisture or other liquids. So, when someone asks, “is microcement porous?”, the correct response is: No, not when professionally applied and sealed.

3. Real-World Benefits of Non-Porous Microcement | Is Microcement Porous

Now that we’ve clarified that microcement isn’t porous, let’s explore what that means in practice:

✅ Water Resistance in Bathrooms and Wet Areas

In places like showers, backsplashes, and floors exposed to water, microcement performs excellently. The sealed surface repels water, keeping mold and mildew at bay—a huge advantage in humid environments like Malta.

✅ Easy Cleaning and Maintenance

Non-porous surfaces don’t absorb dirt or spills easily. All it takes is soap and water to clean it. For optimal maintenance, we recommend using a specialised microcement cleaner—available directly from Kibitec.

✅ Stain Resistance

Because it’s sealed, microcement is much less likely to stain compared to porous materials like unsealed concrete or natural stone. Wine, oil, and coffee can be wiped away easily.

✅ Hygiene-Friendly

With no pores or grout lines, there are fewer places for bacteria and germs to hide—perfect for homes, commercial kitchens, or healthcare settings.

4. Microcement vs. Porous Materials Like Tiles and Concrete | Is Microcement Porous

You might be wondering how microcement compares to traditional tiling or concrete.

Tiles

Tiles are typically not porous, but the grout between tiles is. Grout can absorb water and stains, leading to mold growth over time. With microcement, there are no grout lines, giving it a distinct advantage.

Concrete

Concrete is inherently very porous and requires sealing. Even then, it’s not as sleek or resistant as microcement. Plus, concrete is heavier and harder to apply in thin layers.

Natural Stone

While beautiful, natural stones like marble or travertine are often porous and need ongoing sealing to remain water-resistant. Microcement is more versatile and lower-maintenance.

So, is microcement porous compared to these materials? Absolutely not—and that makes it a smarter, more practical choice for many spaces.

5. The Application Process: Why Professional Installation Matters | Is Microcement Porous

While microcement itself isn’t porous, poor installation can lead to imperfections that allow water or air to seep in. That’s why professional application is critical.

Here’s what the standard process looks like:

1. Surface preparation – Ensure the substrate is stable and clean

2. Primer application – For adhesion

3. Base and finish layers of microcement – Applied in ultra-thin coats

4. Sealing – Two layers of a polyurethane-based sealer

This last step is where the surface becomes water- and stain-resistant. If skipped or done poorly, you may compromise the integrity of the microcement finish.

That’s why it’s always best to trust professionals like Kibitec. Not only do we supply high-quality microcement in Malta, but we also offer installation and expert consultation services. Contact us here for a personalised quote.

Yes, microcement can be used outdoors—patios, pool surrounds, facades—thanks to its excellent sealing properties. Since it’s not porous, it resists Malta’s salty sea air, rain, and sun exposure.

However, outdoor use requires a special UV-resistant and anti-slip topcoat, which protects the surface from weathering. Again, professional application is key to durability.

For Maltese homeowners looking for a stylish, low-maintenance outdoor solution, microcement offers both aesthetic appeal and robust performance.

7. Maintenance Tips for Long-Lasting Results | Is Microcement Porous

Even though microcement isn’t porous, taking care of it will extend its life and preserve its appearance:

• Use neutral pH cleaners

• Avoid harsh chemicals or abrasives

• Reapply the topcoat every 2–3 years for high-traffic areas
