What is Silicone Rendering?
Rendering is the process of applying a mixture to the outside, most frequently, of a building to give a smooth surface. Silicone rendering is a type of render that quite obviously contains silicone, due to the nature of the silicone the render is waterproof (hydrophobic), flexible and breathable which makes it a very popular choice by installers and occupants alike.
Silicone Rendering vs Acrylic Rendering
Acrylic and silicone renders are both new and popular choices so it is important to understand the differences when making a decision as which to choose. Whilst it is not advisable rendering a building in wet and cold conditions, acrylic render takes that bit longer to dry which gives silicone the edge in this respect. Acrylic rendering is known to hold more vibrant colours for longer than other renders, however silicone render has the colour applied to the render itself and thus runs through the render so does mean that cracks are less visible. One of the main advantages of silicone rendering over acrylic rendering are its hydrophobic properties reducing algae growth and dirt build up, meaning far less maintenance is required. It is also more breathable which again makes algae and mould growth less likely on the inside of the building.
That being said, due to its superior properties, silicone render is more expensive than acrylic render so if you are on a budget then perhaps acrylic is the choice, but like the phrase goes, it is also true of render types, “you get what you pay for”, so it is often worth pushing for the better render type.
