Future-Proof Your Home With Silicone Render
What is silicone render?
Silicone render is a contemporary, resin-based external wall coating formulated to combine long-term protection with a refined, low-maintenance appearance. Unlike traditional thick renders, it is a "thin-coat" system: a reinforcing base layer is applied, followed by a fine, flexible silicone-rich topcoat. This construction minimises weight on the substrate while providing a tough, resilient surface.
Key properties and benefits
Water repellence: Silicone resins are inherently hydrophobic, allowing the cured finish to shed rainwater effectively. Water beads and runs off the surface rather than soaking in, reducing the risk of water penetration.
Breathability: Despite being water-repellent, silicone render remains vapour-permeable. It allows moisture vapour from the building fabric to escape, helping to reduce trapped damp and the likelihood of internal condensation or mould problems.
Durability and flexibility: The resin-based formulation offers good elasticity and impact resistance compared with many mineral renders. This flexibility helps the render accommodate minor substrate movement and reduces the incidence of hairline cracking.
Low maintenance: The combination of water repellence and dirt resistance means painted or rendered surfaces retain their appearance longer and typically require less frequent cleaning or redecoration than conventional renders.
Aesthetic versatility: Silicone render is available in a wide range of colours and surface textures, from smooth to fine or coarse aggregates, enabling contemporary or traditional finishes to suit different architectural styles.
Compatibility: It can be applied over suitable masonry, brickwork, concrete and insulated render systems, making it appropriate for new build and refurbishment projects when installed according to manufacturer guidance.
At JVG London, we are fully qualified and highly skilled rendering specialists, delivering a quick, precise application that ensures a flawless, weather-tight finish.
We install our systems by embedding a reinforced fibreglass mesh into the base coat, providing the essential flexible foundation to prevent future cracking.
Our team then applies the through-coloured silicone topcoat with expert floating techniques, achieving a clean, modern aesthetic that eliminates the need for any future painting.
Our Process

Preparation & Masking
Before any material is mixed, the property must be protected. We mask off windows, doors, and pathways. If there is existing render, we check for "blown" areas; these are hacked off and repaired to ensure a solid foundation.

Base Coat
The first layer of the system is the application of a high-polymer base coat. This specialised resin-based mortar is applied directly to the masonry to create a powerful, waterproof bond. This layer serves as the structural foundation for the entire render system, evening out the surface of the building and providing the primary defence against water penetration.

Mesh Reinforcement
While the base coat is still wet, we embed an alkali-resistant fibreglass mesh into the entire surface area. This mesh acts like "armour" for your home, providing the tensile strength needed to absorb the natural movement of the building. This is the secret to a crack-free finish, as the mesh prevents structural shifts from ever reaching the decorative surface.

Smoothing & Leveling
A second pass of base coat is applied to fully encapsulate the mesh, ensuring no fibres are left exposed. The surface is then professionally flattened and "sponged" to create a perfectly level, smooth substrate. This stage is vital because the final silicone top coat is very thin, so the walls must be perfectly true at this point to achieve a flawless finish.

Priming
Once the base coat has fully cured—usually 24 to 48 hours depending on the weather—we apply a colour-matched primer. This layer seals the base coat to control suction, ensuring the top coat doesn't dry too quickly or unevenly. It also acts as a colour foundation, ensuring the final silicone render appears deep, vibrant, and consistent across every elevation.

Top Coat
The final layer is the silicone render itself, hand-applied to the thickness of the grain (typically 1.5mm). Our experts then "rub up" the render using a plastic float in a specific circular motion. This technique brings the aggregate to the surface, creating the uniform, modern, and hydrophobic texture that silicone render is famous for.

Curing & Clean Up
Silicone render is air-drying and becomes shower-proof within just a few hours. Within 24 to 72 hours, the system is fully cured and at maximum strength. We then remove all masking tape and protective films, clean the site thoroughly, and leave your property looking brand new with a finish built to last for decades.
