The Best Masonry Paint? Silicone Paint

What is Silicone Paint?

We often receive enquiries about our Silicone Paint from customers who are looking for high-quality masonry paints, or who are interested in re-rendering their properties. The main questions that they ask tend to be about what the difference is between Silicone Paint and Silicone Render; and what is Silicone Paint for? Well, we hope to answer all of your questions in this blog post!

Silicone Paint is a breathable, hydrophobic topcoat finish which is great for applying over the top of an existing render as you would a normal masonry paint. It’s resistant to water, environmental pollutants and organic growth, so it would be perfect if you live in a busy, built up city or if you live in a humid, rainy environment where your render is susceptible to organic overgrowth.

What is the difference between Silicone Paint and Silicone Render?

It speaks for itself really that Silicone Paint is a masonry paint topcoat, whilst the Silicone Render is a render finish. The only similarities between them are the fact that they both contain Silicone, which provides numerous benefits – but we’ll come to that later!

Our thin coat renders come in different grain sizes ranging from 1mm to 3mm; in contrast, our Silicone Paint does not come in different grain sizes, it’s completely smooth so can be applied on top of the existing render without disrupting the texture.

Silicone Paint is designed to be used as either a masonry paint topcoat to seal in the render underneath (e.g. for use with our Mineral Render), or it can be used as a means of refreshing your render finish if it needs a bit of a spruce further down the line.

Silicone Render is hydrophobic, which means that it repels dirt and organic growth. However, after many years even render with these capabilities can look tired. This is where Silicone Paint comes in really handy as part of your render aftercare because it is also hydrophobic – so it not only refreshes the render but adds another protective layer to top up its lifespan.

Why use a Silicone Masonry Paint?

Silicone Paint provides a super breathable finish, so as part of a render or EWI system it works particularly well. As we know, ingress of water and moisture is detrimental to rendered properties and to external wall insulation. For EWI, if water enters the system it can reduce its thermal capabilities and the water can damage the system during the freezing and thawing process. Ingress of water within a render-only system is particularly bad,  allowing the water to cause damage to the render. It can seep into the walls of the property and cause damp patches on the internal walls, especially with solid wall properties.

The Silicone Paint acts as a protective barrier against this problem. Its breathability allows water and moisture to escape through the surface of the paint and it prevents moisture from passing through because the silicone within the paint repels water vapour. Because of its vapour permeability, Silicone Paint is also frostproof – frost will not cause damage by settling on its surface or within the actual masonry paint itself.

We always recommend to our customers that our Mineral Render should be sealed in with a high-performance masonry paint such as Silicone Paint. Mineral Render is our fastest-drying render which is perfect for cold climates, however, its ingredients mean that if it’s exposed to the elements for too long it can be susceptible to lime bloom. This is why it’s necessary to apply Silicone Paint over the top of it, to prevent water from passing through to the render underneath and causing the formation of lime bloom.

Silicone Paint can be Matched to the Coloured Render Underneath!

If you’ve used one of our coloured renders, then you can very easily buy a Silicone Paint in exactly the same colour to match it to the existing render. We offer a same-day colour mixing service using our render colour machine which can tint your Silicone Paint into thousands of different colours, so even if your render does not come from EWI Pro we will be able to match up the paint for you!

Silicone Paint is Great for Interiors and Exteriors!

We’ve previously talked a lot about render and how Silicone Paint can be used as a masonry paint in addition to your render finish as a protective topcoat, however, many people aren’t aware that Silicone Paint can be used for interiors as well as exteriors!

We’ve heard of people using Silicone Paint in their bathrooms because it’s a really waterproof paint and is perfect for the humid environment of a bathroom. We’ve also heard of people who have previously suffered from problems of damp in their home and have used Silicone Paint as a future deterrent because of its breathability. One of our members of staff has also used silicone paint on his garden wall to prevent organic growth. We think all of the above uses are great ways to utilise Silicone Paint!

What is Silicone Coloured Render?

This week we are taking a look at our top of the line, through-coloured, silicone coloured render in order to offer a little bit more technical info about why you would want to choose coloured silicone render, and what it can do for you and your home!

To start with, and to state the obvious, silicone render contains silicone. If you’re not aware of exactly what silicone is, it’s basically a polymer which is rubbery and heat resistant – it has a molecular structure built up by a large number of similar molecules which are bonded together. Silicone is typically used in adhesives, lubricants, medicine, make up, cooking utensils and thermal and electrical insulation. A great thing about Silicone is that it has a low thermal conductivity – so it’s perfect when used as part of an external wall insulation system!

Silicone rubber is widely used in the construction industry because it is known for its tensile strength, reliability and longevity. That’s why silicone is great for use in renders, because it provides an incredible level of flexibility which will help to prevent cracking in the long run.

Not only is silicone flexible but it also offers a high level of water resistance, but importantly at the same time it is vapour permeable. What this means is that your render won’t absorb any water, but it will allow water vapour from the inside to escape through it (water vapour moves from warm areas e.g. inside to cool areas e.g. outside). This will contribute towards the prevention of damp within your home by letting the moisture escape rather than building up within your insulation system and your walls. Moisture and condensation can hugely affect the thermal performance of insulating materials, so it’s a pretty important factor to consider.

Because of its breathability, we recommend that silicone coloured render is great for use with mineral wool systems – Rockwool insulation boards offers unsurpassed levels of breathability, so if you live in a humid, damp area then this is the perfect system!

We have found that silicone render works really well if you’re installing it in a place where algae and moss or organic growth are likely to occur, such as near water or plant life. This is because it is highly resistant to organic growth. What this means is that in the long run you are much less likely to have to clean your render, and even less likely to have to re-render before the end of its lifespan.

How to apply Silicone Coloured Render

Silicone coloured render comes as a ready-to-use mix so you don’t need to add anything to it before use. It is advisable that you give it a bit of a stir first to ensure that all the colour pigments are evenly distributed throughout (if you’ve gone for a coloured render).

To apply the silicone coloured render, you need to first install the basecoat mesh layer (EPS Basecoat Adhesive and fibreglass mesh embedded within it). This will create a smooth, even surface for you to render onto – you wouldn’t be able to apply the thin coat coloured render directly to the substrate because it is such a thin texture that you would be able to see brickwork etc underneath.

Once the basecoat layer has dried, you can use a stainless steel trowel to apply the coloured render to the substrate. To create an even, textured finish you will then need to rub up the surface of the of the render using circular motions with a plastic render float.

You will need to ensure that you have enough people on site to be able to apply the render to an entire wall at once. If you attempt to apply the coloured render section by section, then you will find that when it dries there will be a scarring effect where the different render sections meet.

To apply silicone render, you will also need the right weather conditions. Rain, wind or too hot/cold temperatures can have a negative impact upon the finished result. Make sure that it is not due to rain during installation and drying time.

Coloured Renders: Silicone Render vs Silicone Silicate Render

Silicone coloured render and silicone silicate coloured render are the twin siblings of the EWI Store render group. Both renders are well matched in terms of performance, the only real difference between them is that silicone silicate contains sand granules which makes it slightly less resistant to organic growth.

Silicone silicate is one of our most popular renders. It’s also the slightly cheaper than silicone render because of the addition of sand, which is a less expensive material. However, for the performance of the render you aren’t losing out by paying less.

Why use Silicone Coloured Render?

Using coloured render on your home can have a dramatic effect on its aesthetic appearance. Throughout the UK, there are thousands of tired, dull looking properties that are crying out for a facelift. Our Silicone coloured render comes in thousands of colours because we have specialist colour mixing facilities on site which enable us to add any amount of colour pigment and match any shade. This means that as soon as you place your order, we can mix up your coloured render and send it out for next day delivery. We can also match NCS colours, and if you are looking to replace old, cracked render and you want to match the new coloured render to the exisiting colour we can do this too! You can check out our full colour range by ordering one of our colour charts, or you can buy one of our tester pots.
