Concrete Mix -5mm

Concrete Mix – 5mm is expertly engineered for precision-based construction and finishing tasks that demand smooth surfaces and fine detailing. Composed of a fine 5mm aggregate, this mix is ideal for applications such as floor levelling, surface rendering, tiling bases, and decorative concrete finishes. The smaller particle size allows for a more even and refined texture, resulting in a cleaner, smoother finish that’s both aesthetically pleasing and functionally sound.

Its superior workability ensures easier application, making it perfect for use in confined or interior spaces where maneuverability and accuracy are essential. This mix is particularly well-suited for indoor projects like kitchens, bathrooms, hallways, and commercial interiors, where appearance and texture play a vital role alongside strength and durability.

Beyond its application ease, Concrete Mix – 5mm also provides reliable structural performance for light-duty construction tasks. It offers strong bonding characteristics, resistance to surface cracking, and a quick, consistent finish — minimizing surface imperfections and preparation time for further layers such as tiles, coatings, or polish.

Whether you’re a professional contractor or a DIY enthusiast, this mix is your go-to choice for precision concrete work that doesn’t compromise on quality or finish.

Explore frequently asked questions about our 5mm Concrete Mix, made for smooth finishes and precise applications. Here, you’ll find details about its best uses, compatibility with floor finishes, mixing ease, curing process, and how it performs in light construction and interior projects.

This mix is perfect for applications that require a fine, smooth finish. Common uses include floor levelling, screeds, bathroom and kitchen underlays, and tiling bases. It’s also effective for patching minor surface damage on concrete due to its flowability and smooth texture.

Yes, it’s highly recommended for indoor projects. Its fine texture and reduced dust production make it ideal for enclosed spaces. Additionally, it creates a neat, level surface that’s ready for tiling, painting, or sealing, which is often required in interior renovations.

Yes, once fully cured, it provides enough strength to support regular foot traffic. For residential spaces, walkways, and indoor flooring, this mix delivers the required durability. However, for areas with heavier loads or machinery, a stronger mix like 13mm may be more suitable.

In most cases, reinforcement is not required, especially for non-structural applications. However, in larger floor areas or where there’s a risk of movement or cracking, light mesh or fibre reinforcement can be added to increase crack resistance and flexibility.

It usually sets within 2–4 hours, and light foot traffic can resume after 24 hours. Full strength is achieved in 7–10 days. For best results, keep the area moist and avoid placing weight on it too early to prevent surface cracks.

Absolutely. Its smooth and refined surface makes it an excellent base for decorative finishes like staining, polishing, or colored concrete overlays. It allows for a high-end look while maintaining functional durability.

Yes. The smaller aggregate makes the mix easier to combine with water manually. It’s ideal for smaller projects, DIY jobs, or tasks in tight areas where using machinery isn’t feasible.

Yes, it’s compatible with radiant heating systems. When poured correctly over heating pipes or cables, it ensures even heat distribution and forms a strong, smooth layer ready for finishing materials.
