Silicone Render vs. Traditional Sand & Cement: Which is right for your Kent home?
If you're considering having your home rendered, one of the first decisions you'll face is choosing the right system. Two of the most common options are silicone render and traditional sand & cement render — and while both can transform the look of a property, they work very differently and suit different homes and budgets.
At Ace Rendering Specialists, we've worked on hundreds of properties across Kent and South East London over 25 years. Here's what you need to know before you decide.
What is Traditional Sand & Cement Render?
Sand and cement render is the classic rendering method — a mix of sand, cement, and water applied directly to the wall. It's been used on homes across the UK for decades and, when done properly, creates a strong, durable finish.
It works well on older or solid-wall properties and is generally lower in upfront cost. However, it is rigid, which means it can be prone to cracking over time as the building moves slightly with temperature changes. Once cracks appear, water can get in — leading to damp, staining, and more costly repairs down the line.
What is Silicone Render?
Silicone render is a modern polymer-based system that's become the go-to choice for homeowners wanting a long-lasting, low-maintenance finish. It's flexible, breathable, and highly weather-resistant — making it especially well-suited to Kent's wet winters and variable climate.
Key advantages of silicone render include:
• Flexibility — moves with the building, dramatically reducing the risk of cracking
• Self-cleaning properties — rain washes dirt from the surface, keeping it looking fresh
• Colour-through finish — the colour is integral to the render, so it doesn't need painting
• Breathability — allows moisture vapour to escape, preventing damp build-up
• Longevity — when applied correctly, silicone render can last 20–30 years with minimal maintenance
Which is better for your home?
The right choice depends on your property type, your budget, and what you want from the finish.
Traditional sand and cement render is a solid option for older properties, particularly where you want to match an existing finish or where budget is the primary concern. It's also suitable where a harder, more textured surface is preferred.
Silicone render is the better long-term investment for most modern homes or properties undergoing a full exterior refresh. The reduced maintenance, superior weather resistance, and cleaner appearance make it worth the additional upfront cost — particularly across Kent and South East London, where damp and driving rain are a regular consideration.
Our Recommendation
We specify silicone render on the majority of projects for a simple reason: it performs better over time and gives homeowners fewer headaches. That said, we always assess each property individually and will advise you honestly on the best system for your specific situation.
