Silicone render is a notoriously high-performance flexible render. It offers breathability, crack resistance and self-cleaning capabilities. It’s a very popular choice for customers as it is commonly associated with coloured render.
Is silicone render any good?
Silicone or silicone silicate render is a top of the range system that has a number of fantastic advantages. The Silicone render system should be applied along with a fibreglass mesh layer which provides extra flexibility. It is highly durable, with some manufacturers offering over 25 years warranty. It is breathable.
How long does silicone render last?
How long does silicone render last? In general, silicone renders are more durable and reliable than the traditional mixtures. This is especially true when it’s combined with an adhesive base coat and mineral. As such, the average lifespan of silicone rendering is between 25 – 30 years.
Is silicone render better than K render?
Silicone renders are generally termed as ‘thin coat renders’ because they’re applied in a very thin layer on top of a reinforced basecoat and have the advantage of being especially crack-resistant. Silicone rendering is more premium and is comparatively more expensive than monocouche rendering.
What causes cracking in rendering?
Cracking can be caused by a variety of factors including excessive porosity of the substrate, shrinkage within the substrate, reflective cracking, lack of reinforcement or incorrect movement joints.
What’s the difference between acrylic and silicone render?
Similar to acrylic render, silicone render is cement-based with silicone mixed in for improved performance. It makes the render more low-maintenance and water-resistant, but unlike acrylic render it doesn’t impair breathability. Unfortunately, this improvement comes at a cost – both to the buyer and the environment.
Is silicone render better than sand and cement?
With a silicone render system, you can rest assured that the facade will not crack over time and will likely stay much cleaner than either sand and cement or monocouche render, therefore providing a render system that will last for years to come.
Can you apply silicone render over existing render?
Additional coats of render can only be applied safely when the existing work is sound and has satisfactory adhesion over the whole area involved. Further rendering coats should not be applied over soft, friable material, or where the existing render is greater than 15mm thickness.
Is silicone render expensive?
Is silicone render expensive? Silicone render is generally slightly more expensive than cement or acrylic options, but it’s much quicker to apply and usually lasts longer without the worry of cracking, scratches and other damage.
Does silicone render stop damp?
It stops penetrating damp Adding a layer of render to the outside wall of the home blocks the path of water into the property and prevents this form of damp from occurring.
What are the three types of rendering?
Generally, modern render can be divided into three main types: mineral, acrylic and silicone – but there are other options, as I’ll present later.
What is the best material for rendering?
The best type of sand to use is rendering or plastering sand. Coarse sand is usually used for the base layer, and sand that has a slightly fine texture as the top layer. Therefore, you can make use of building sand for the top or base layer.
What is the best type of rendering?
Lime plaster is a great option for those looking for a breathable house rendering system. The advantages of lime render in include: It is more flexible than cement. It is breathable so prevents problems with moisture getting trapped within the wall — a common problem where cement renders are applied to old walls.
Is cracked render a problem?
Look out for cracking or bulging render — both indicate trouble. In fact, cement render should never be applied to old solid wall buildings. The most common cause of render cracking and bulging, however, tends to be frost getting to moisture trapped between the render and the wall.
Can cracked render be repaired?
Technically speaking, render crack repair isn’t possible as the render itself can’t be repaired once it’s cracked. Instead, the render needs to be knocked off the wall and replaced with a completely new layer.
Are cracks in render normal?
Cracked render is normally caused by small movement in the foundations of your home or building. These are perfectly normal and are caused by cold spells when the ground contracts, and hot periods when it expands. This slight movement causes hairline cracks in your render.
Is silicone render easy to apply?
Silicone is easy to apply – Where other renders have a painting stage, thin coats can be done in just a few hours on a properly prepared wall. Despite a slightly higher cost, your job will be done in much less time than a traditional render.
What is the smoothest render?
1.5mm is our most popular, as it achieves a smooth surface but with a very slight texture when you look up-close. 1.5mm is also easier to apply than a 1mm render.
Is silicone render waterproof?
Choosing a Waterproof Render – The Premium Bio Silicone Render. It is incredibly waterproof, which means that water is repelled from the surface of the render rather than being absorbed into the material. When water hits the surface, it forms droplets that roll straight off.
Is sand and cement render good?
Sand and cement render is a very outdated, low-performance solution to creating a decorative finish on your property; these days, thin coat, through-coloured renders and breathable scratch renders are a more popular alternative for installers and homeowners alike.
How long does sand and cement render last?
Taking into consideration the flexibility, technology and how it can be maintained (a light jetwash every now and then) means a self-coloured render system can last around 5-10 years whilst a sand and cement or lime render system may only last a couple of years when you take into consideration the weather, movement of Mar 12, 2020.
