Frequently Asked Questions (FAQs)

1. Can I apply the system over painted render that’s faded or peeling?

Licata’s existing paint render systems are suitable for use over sound, stable surfaces that have been properly cleaned and repaired. If the existing render or painted wall shows peeling or cracks, it must be treated and primed before applying the new coat render system. This preparation ensures the new layer adheres effectively and maintains its protective properties.

Once the surface is ready, applying the Licata render system provides a durable, breathable, and water repellent finish. It helps protect the exterior wall against damp, mould, and algae while delivering a smooth, attractive finish that performs reliably in all weather conditions.

2. How do I check if existing render is sound and stable?

Before applying any new render paint, check the surface for hollow patches, loose material, or visible cracking. A tap test on the existing render can help detect weak areas that may need repairs or a suitable primer to stabilise the substrate.

When the surface is properly prepared, Licata’s coat render system will adhere securely, creating a strong, weather resistant, and crack-resistant coating. This step ensures better protection, longer life, and consistent colour performance across exterior walls.

3. Will applying this system over existing render increase wall thickness significantly?

Licata’s thin coat render system is designed to refresh existing surfaces without adding excessive build-up. The lightweight and flexible layer provides a smooth and modern finish that maintains the original wall profile.

It is also a cost effective alternative to full re-rendering. By choosing this one coat render system, property owners can achieve a high-quality decorative finish and long-term protection without the higher expenses associated with replacing the entire render.

4. What is the expected lifespan of the coating over existing render?

When installed correctly, Licata’s external render systems are known for their long-lasting performance. The breathable structure, water vapour permeability, and glass fibre mesh reinforcement ensure strong resistance to cracking and damp.

The system can last over two decades with minimal maintenance when applied over a properly prepared surface. Regular inspection and gentle cleaning will help preserve the colour, durability, and overall appearance of the render paint coating.

5. Can I use standard masonry paint on top of this system later?

Licata’s silicone and acrylic render systems are designed to deliver a self-sufficient finish, so standard masonry paints are generally unnecessary. The colour and protection are built into the surface, keeping the exterior wall bright and well-protected.

If repainting is desired, only highly breathable masonry paints should be used to avoid trapping moisture. This ensures the render system remains flexible, water repellent, and resistant to algae growth over time.

6. Will the system bridge existing hairline cracks or surface imperfections?

Yes, Licata’s render systems include glass fibre mesh that enhances crack resistance and stability. It helps bridge small surface flaws and delivers a smooth, uniform appearance even on aged or uneven walls.

For deeper cracks, using an appropriate primer and base coat helps strengthen the area before the final render is applied. The resulting weather resistant coating protects the exterior wall from moisture and maintains a consistent finish through varying conditions.
