Frequently Asked Questions (FAQs)

1. What surface preparation is needed before applying a blockwork render system?

Before applying the Licata blockwork render system, the block work or concrete block surface must be clean, dry, and stable. Any loose materials or dust should be removed to help the base coat adhere evenly. This preparation improves the structural integrity of the render system and allows for smooth, consistent coverage across masonry walls and concrete surfaces.

Fibreglass mesh or lightweight reinforcement is then embedded within the multi coat system to strengthen the render layers. Licata’s polymer modified renders, available in a variety of grain sizes and textures, achieve excellent crack resistance and a durable, weather resistant decorative finish that protects against algae growth and moisture.

2. How is crack control managed in a blockwork render system?

Licata’s render systems are designed with advanced crack resistance technology that allows movement without compromising durability. A multi coat system incorporating a polymer modified base coat and fibreglass mesh ensures excellent flexibility and adhesion. These layers protect the walls from cracking caused by substrate movement or external conditions.

The blockwork render system combines water vapour permeable materials and a weather resistant surface to maintain long-term strength and appearance. This method provides a cost effective and durable finish compared to traditional sand cement renders, while still offering the design freedom of self coloured or textured decorative finishes.

3. Can blockwork render system be applied in damp or cold weather?

While Licata’s render systems provide excellent weather protection once cured, applying render in damp or freezing conditions is not suitable. Low temperatures slow down the curing process and may affect the strength of each coat. Ideally, thin coat renders should be applied during mild, dry conditions to achieve optimal coverage and bond strength.

Professional installers carefully monitor weather forecasts and substrate temperature before applying render. This ensures that each layer, from the base coat to the decorative finish, performs reliably and maintains its water vapour permeable and weather resistant properties throughout the project.

4. How do you repair or patch damage to the blockwork render over time?

Minor repairs on a Licata blockwork render system are straightforward and cost effective. Small areas of damage can be cleaned and refilled using the same polymer modified render materials used in the original application. This approach ensures that colour, texture, and grain size match seamlessly with the surrounding render finish.

When patching, a thin coat render reinforced with fibreglass mesh may be used to restore flexibility and prevent future cracks. Regular cleaning to remove dirt or algae growth and occasional surface checks keep the system looking attractive while protecting buildings against moisture and environmental wear.

5. What movement joints or control joints are required in a render over block work?

Movement joints are essential in any render system applied to blockwork or concrete block walls. They allow natural expansion and contraction without compromising the coat’s structural integrity. Joints should align with the substrate and follow the layout of the masonry to maintain even stress distribution across the surfaces.

Licata’s render systems are designed to integrate smoothly with control joints, ensuring that flexible, weather resistant, and decorative finishes remain intact over time.
