Self-Leveling Overlay	3-10mm	Can withstand heavy foot traffic	Best for repairing uneven concrete, warehouses, industrial floors	Poured and spreads itself, cures quickly	£25 - £80 per m²	Natural concrete look, can be polished	Minimal maintenance, reseal every 5+ years
Decorative Concrete Overlay	3-12mm	Stronger than traditional concrete	Best for stamped or textured concrete effects for patios & driveways	Troweled or sprayed, textured finish applied	£40 - £100 per m²	Stamped stone, wood, tile, or brick look	Sealing required to maintain colour & texture

🔹 What is the best concrete overlay for worn-out floors?

The best concrete overlay depends on your needs. Microcement is great for a seamless, modern finish. Self-leveling overlays are ideal for fixing uneven floors, while decorative overlays offer custom patterns and textures for aesthetics.

🔹 How long does a concrete overlay last?

A properly applied and sealed concrete overlay can last 10-20 years. The lifespan depends on the type of overlay, foot traffic, and maintenance. Regular resealing helps extend durability.

🔹 Can I install a concrete overlay over an existing floor?

Yes, as long as the existing floor is structurally sound. Any cracks or damage should be repaired before applying an overlay to ensure a stable and durable surface.

🔹 Are concrete overlays waterproof?

Some overlays, like microcement, can be made waterproof with the right sealers. Self-leveling and decorative overlays may require additional sealing to prevent water damage.

🔹 Do I need to seal a concrete overlay?

Yes, sealing is essential for protection against stains, moisture, and wear. The type of sealer depends on the overlay type and whether the floor is indoors or outdoors.

✔ Microcement overlays are ideal for modern, seamless finishes that mimic polished concrete but with a much thinner application (2-3mm). They are perfect for residential interiors, bathrooms, and high-end commercial spaces due to their stylish, contemporary look. Microcement adheres well to most surfaces, including tiles and existing concrete, making it a great choice for renovations where removing the old flooring is impractical. However, it requires skilled application and regular sealing to maintain durability.
✔ Self-leveling overlays are the best option when floor unevenness is a concern. If the existing surface has dips, cracks, or inconsistencies, this overlay helps create a smooth, level base with minimal effort. It is commonly used in warehouses, commercial buildings, and large-scale renovations where time and efficiency are critical. Self-leveling overlays dry quickly, allowing for fast turnaround times, but they may lack the decorative appeal of other overlays unless additional coatings or stains are applied.
✔ Decorative overlays provide the most design flexibility, making them ideal for stamped, textured, or stained finishes. These overlays are commonly used in driveways, patios, pool decks, and retail spaces where visual appeal is a priority. Unlike microcement or self-leveling options, decorative overlays can be made to mimic stone, wood, or tile at a fraction of the cost. However, they require skilled installation and ongoing maintenance, especially in outdoor environments where exposure to weather can lead to wear over time.
