Concretta FS Microcement Plaster FAQs: What You Should Know

Concretta FS Microcement Plaster FAQs answer the most common questions about installation, showers, sealing, durability, cost, VOC safety, maintenance, and long-term performance. This guide explains how Concretta FS microcement plaster works, where it can be used, and what makes it a reliable choice for modern interiors and wet areas.

Microcement plaster is a high-performance, ultra-thin cement-based coating that can be applied to showers, walls, floors, ceilings, and even furniture. At just 3 mm thick, it creates a seamless, modern finish without grout lines. Premium microcements like Concretta are durable, water-resistant when sealed, available in many colors and textures, and can be applied over existing tiles for cost-effective renovations.

Yes, microcement can be used in showers, but proper installation and sealing are essential. When applied over a stable, waterproof substrate and sealed correctly, it creates a seamless, water-resistant surface ideal for showers and wet rooms. Concretta uses PlasterGuard for walls and PlasterSeal Plus for floors, countertops, and benches, ensuring durability, waterproofing, and a sleek, modern finish.

Priming microcement depends on the substrate. For most surfaces, a mineral primer such as Quartz Primer by Meoded is recommended to ensure adhesion and a uniform finish. However, Meoded Concretta microcement does not require a primer when applied over tile and stones, as it is formulated to adhere directly to these substrates.

Yes, Concretta microcement is formulated to adhere directly to tiles, making it ideal for shower installations. It is water-resistant, and when its designated sealers are applied, they form a protective waterproof barrier over the microcement. This makes Concretta a perfect choice for showers, wet rooms, and other moisture-prone areas while providing a seamless, modern finish.

Yes, microcement plaster should always be sealed, especially in showers and wet areas. Sealing protects the surface against water, stains, and daily wear, ensuring long-lasting durability and longevity. For Concretta, vertical surfaces use PlasterGuard, while floors and horizontal features require PlasterSeal Plus. Properly sealed, microcement stays water-resistant, easy to clean, and retains its seamless, modern finish over time.

On a materials and labor basis, microcement usually costs more upfront than standard tile, depending on the tile type. However, Concretta microcement can be applied directly over existing tile, avoiding demolition and re-tiling costs. Its seamless finish eliminates grout maintenance. With only occasional resealing required, microcement proves more cost-effective over time compared to tiles that need cleaning, re-grouting, or replacement.

Microcement has a long life expectancy when applied and maintained correctly, typically lasting 10–20 years or more. Its life expectancy depends on proper substrate preparation, application, and sealing. Both horizontal and vertical surfaces, including floors, walls, and countertops, should be resealed every 3–5 years to maintain water resistance, prevent wear, and preserve Concretta’s seamless, modern finish over time.

Microcement is very durable and difficult to remove, usually requiring professional grinding, which can damage the surface beneath. It’s usually easier to simply cover it. You can tile, repaint, or apply a new microcement finish over the existing layer. For showers, lightly sanding off the sealer is typically enough to allow new tile to adhere without removing the microcement itself.

Mold generally does not grow on microcement because the surface is seamless, non-porous once sealed, and doesn’t absorb moisture. Unlike traditional tiles, microcement has no grout lines, which are often the main areas where mold and mildew develop. With proper sealing and regular cleaning, microcement remains highly resistant to mold, making it an excellent choice for bathrooms and showers.

Sealing frequency depends on the type of microcement used. Meoded’s Concretta microcement typically needs resealing every 3–5 years, depending on traffic and exposure. Regular cleaning with non-abrasive products also helps extend the life of the sealer and maintain the finish.

Black marks on microcement are known as carbon marks. They occur when a stainless steel trowel is used with heavy pressure on light-colored microcement or any other type of plaster, causing the surface to “burn” and leave dark carbon streaks. The easiest way to prevent this is by using a Whiteout Trowel by Meoded, which eliminates carbon markings.

The best microcement depends on durability, application ease, and performance in wet areas. Meoded’s Concretta stands out for its strong, long-lasting finish, excellent water resistance, and smooth modern look. It applies easily over surfaces like tile, making it a reliable, versatile choice for walls, showers, and low-traffic floors.

Microcement is generally non-toxic, with the main concern being chemical emissions from coatings. Meoded’s Concretta is a natural, eco-friendly microcement with 0 VOCs, meaning it releases virtually no harmful compounds once cured. This makes it a safe, healthy choice for indoor spaces, including bathrooms, kitchens, and homes with children or pets.

To keep microcement clean, ensure it is properly sealed. Remove dust or debris regularly, then wipe with a damp cloth and warm, soapy water or a mild, non-abrasive cleaner. Avoid harsh chemicals or acidic products, and reseal periodically to maintain water and stain resistance, especially in high-traffic or wet areas like showers, kitchens, and bathrooms.

Yes, you can drill into microcement, but it requires care. Use a carbide-tipped or masonry drill bit and go slowly to avoid cracking the surface. Mark the spot, drill at a low speed, and apply light pressure. For walls with tiles beneath, consider using a wall plug or anchor to ensure a secure fix without damaging the microcement.

Microcement resists cracking, chipping, and staining when applied over a stable, well-prepared substrate and properly sealed. Consistent maintenance, timely resealing, and mindful use in high-traffic or wet areas help maintain its durability and keep the surface looking smooth, clean and flawless for years.

Versatile microcements like Meoded’s Concretta can be applied to almost any surface, including tiles, stone, fiberglass, concrete, plaster, drywall, and wood. Its thin, adaptable coating is ideal for interior & exterior walls, low-traffic floors, ceilings, countertops, and furniture, creating seamless, modern finishes suitable for both residential and commercial spaces.

Microcement is usually applied in 2–3 base coats for proper thickness and adhesion, followed by a finish coat for smoothness. Premium microcements like Meoded’s Concretta require just 2 coats and are paired with PlasterGuard sealer for walls and PlasterSeal Plus, a high-quality polyurethane sealer, for floors to ensure water and stain resistance.

Microcement can be challenging for DIY projects because it dries quickly and requires precise application for a smooth, seamless finish. Professional installation is recommended to ensure proper substrate preparation, even layering, and correct sealing, preventing issues like cracks, uneven texture, or water damage, especially in wet areas such as bathrooms and kitchens.

Meoded’s Concretta microcement offers extensive customization with 88 curated colors that can also be color-matched to any desired shade. Finishes range from smooth and polished to rough or natural concrete textures, allowing for versatile, modern designs on walls, floors, and furniture.

Microcement is applied in thin layers and dries quickly, so achieving a smooth, consistent finish requires a skilled installer. Improper application or an unstable substrate can cause uneven texture, pinholes, or hairline cracks. It must be properly sealed and periodically resealed to remain water and stain-resistant; without maintenance, it can absorb stains and become harder to clean.

Most microcements are designed to be low-VOC or zero-VOC, but it depends on the brand and formulation. For example, Meoded’s Concretta is completely 0 VOC, making it safe for indoor use. Once cured and sealed, it emits virtually no harmful chemicals, making it suitable for bathrooms, kitchens, and other interior spaces.

Microcement is not inherently waterproof; its water resistance comes from specially designed sealers that form a protective barrier over the surface. Meoded’s Concretta achieves full water resistance when paired with its designated PlasterGuard for walls and PlasterSeal Plus for floors, effectively repelling water and protecting the finish.

Yes, microcement is highly durable when applied over a stable, well-prepared substrate and properly sealed. It resists wear, scratches, and stains, making it suitable for walls, low-traffic floors, and furniture. While it is thin, careful installation and maintenance ensure long-lasting performance, even in kitchens, bathrooms, and other everyday-use areas.
