Silicone vs Cement Render: What’s Best for Your Home?

Choosing between silicone vs cement render can be difficult if you’re not familiar with the differences. Both are popular finishes for external walls, but they vary in flexibility, durability, and cost. Let’s break it down so you can choose the right render for your property.

1. Flexibility and Crack Resistance

Silicone render is far more flexible than traditional cement render. It moves with the building, which means fewer cracks over time — especially on homes prone to minor settlement or weather expansion.

2. Breathability and Water Resistance

Silicone render is breathable and water-repellent, allowing moisture inside the wall to escape while keeping rain out. Cement render, while strong, is less breathable and can trap moisture, especially on older homes without cavity walls.

3. Maintenance Requirements

Cement render often needs repainting and can attract algae. In contrast, silicone render is self-cleaning and holds its colour for many years. It’s a low-maintenance option ideal for busy households.

4. Appearance and Finish

Silicone render comes pre-coloured with a smooth, consistent finish. Cement render usually needs painting and may show trowel marks or surface inconsistencies, particularly if applied by hand.

5. Cost and Installation Time

Cement render is cheaper up front, but may cost more over time due to upkeep. Silicone is more expensive initially but offers long-term savings in reduced maintenance and repainting.

Which One Should You Choose?

For modern homes or clients wanting a low-maintenance finish, silicone render is usually the best choice. For tighter budgets or temporary projects, cement render might do the job — but be aware of the upkeep involved.
