Frequently Asked Questions (FAQs)

1. What substrates or surfaces can the Concrete Repair Render System bond to?

Licata’s Concrete Repair Render System is suitable for most concrete surfaces, including vertical and overhead applications such as façades, soffits, and ceilings. Its strong adhesion allows it to bond effectively to damaged concrete, brick, and other mineral-based substrates, creating a reliable base for finishing coatings or decorative renders.

This high-performance system is specifically designed to integrate seamlessly with the surrounding concrete, restoring the original structure without compromising its strength or appearance. It’s an ideal solution for both residential and commercial buildings requiring long-term protection and stability.

2. How thick can each layer of the repair render be applied?

Each layer of Licata’s repair mortar can typically be applied up to several millimetres thick, depending on the extent of the cracks or spalling being treated. The concrete repair mortars are shrinkage compensated, helping maintain a smooth, even surface without cracking during curing.

When carrying out structural repairs, the thickness may vary based on project needs. Whether it’s a small cosmetic repair or a structural restoration, the repair process ensures consistent results and long-term durability, even across vertical or overhead applications.

3. What is the typical curing time before finishing or overcoating?

The curing time for Licata’s concrete repair render system depends on environmental factors such as temperature and humidity, but under standard site conditions, surfaces can generally be finished or overcoated within a few days. This ensures an effective repair without compromising the durability of the final coating.

Licata’s high-performance repair products allow controlled drying to minimise shrinkage and promote long-term durability. Once cured, the system provides a smooth finish suitable for decorative renders or fairing coats, ensuring the repaired area blends seamlessly with the surrounding concrete.

4. Can this render system be used in freeze-thaw climates or exposed to salt spray?

Yes, Licata’s concrete repair render system offers excellent resistance to chloride ingress, moisture, and frost, making it suitable for exterior concrete areas exposed to harsh conditions. The polymer modified composition provides protection against corrosion, chloride attack, and further deterioration.

This makes it ideal for coastal structures, driveways, and infrastructure where steel reinforcement may be at risk. Its long-term durability ensures the repaired elements remain structurally sound despite continuous exposure to environmental stress.

5. How do I prepare the damaged concrete before applying the repair render?

Proper preparation is essential for any concrete repair. All defects, loose material, and corroded steel reinforcement should be removed to expose a clean, stable surface. Any low concrete cover areas can be treated using a passivating mortar to prevent further corrosion before the repair mortar is applied.

Licata’s repair process ensures the substrate is primed for strong adhesion and maximum protection. Cleaning with appropriate materials and ensuring dry, dust-free surfaces supports better bonding and an effective repair, extending the structure’s lifespan.

6. What is the expected lifespan or maintenance schedule once repaired?

When applied correctly using Licata’s concrete repair products, the system can provide long-term durability that often exceeds 20 years with minimal maintenance. The range includes high-strength, trowel-applied repair mortars designed to restore and protect concrete structures against spalling and corrosion.

Routine inspections of exterior concrete areas and structural elements help ensure the protection layer remains intact. With regular checks and simple upkeep, this durable system will continue to safeguard your buildings and structures, ensuring long-term performance at a cost-effective rate.
