 What Is Silicone Render?

Silicone render is a premium exterior wall coating made from a blend of silicone resins, minerals, and aggregates. Unlike traditional cement-based renders, silicone render is highly flexible, breathable, and resistant to cracking. It’s designed to protect buildings from harsh weather while providing a smooth or textured finish.

Key Features:

• Breathability: Allows moisture to escape, preventing dampness (more on this later).
• Waterproof: Acts as a protective barrier against rain.
• Flexibility: Resists cracking due to temperature changes.
• Low Maintenance: Requires minimal upkeep compared to older render types.

Benefits of Silicone Render

• Aesthetic Versatility: Available in a wide range of colours (including popular Johnstones silicone render colours and K Rend silicone render shades).
• Longevity: Lasts 25+ years with proper care.
• Energy Efficiency: Improves insulation when paired with external wall insulation (EWI) systems.
• Eco-Friendly: Breathable properties reduce mould growth, promoting healthier indoor air.

How to Apply Silicone Render: Step-by-Step Guide

Tools Needed: Trowel, hawk, base coat, primer, silicone render mix (e.g., Weber silicone render or Atlas silicone render).

Steps:

1. Surface Preparation: Clean walls, repair cracks, and apply a primer (like silicone render primer).
2. Base Coat Application: Use a cement-based or insulated base coat for adhesion.
3. Mixing: Follow manufacturer guidelines (e.g., Baumit silicone render).
4. Application: Apply in two thin layers (2–3mm thickness each) using a trowel.
5. Finishing: Create textures like smooth, scraped, or Tyrolean render-style patterns.

Drying Time: Typically 24–48 hours, depending on weather.

 Silicone Render Cost: What to Expect

• Per m² Cost: £30–£50 (materials + labour).
• Whole House: £5,000–£15,000+ (varies by size and complexity).
• Factors Affecting Price:
  • Wall condition (repairs increase costs).
  • Choice of brand (e.g., K Rend silicone render vs. Johnstones silicone render).
  • Additional insulation (EWI systems).

Can You Paint Silicone Render?

Yes! Use silicone render paint for touch-ups or colour changes. Ensure the paint is breathable to maintain the render’s properties. Brands like Johnstones silicone render paint offer compatible options.

How to Clean Silicone Render

• Regular Cleaning: Use a soft brush and mild detergent.
• Stubborn Stains: Pressure wash on a low setting.
  Avoid abrasive tools to prevent damaging the finish.

Is Silicone Render Breathable?

Absolutely! Its microporous structure allows moisture vapour to escape, making it ideal for older buildings prone to damp.

Silicone Render vs. Acrylic Render: Key Differences

Common Silicone Render Problems (and Solutions)

• Cracking: Rare, but caused by poor application. Fix with flexible filler.
