Can you paint over K Rend?

Is your house currently rendered in K Rend? Has it been a while since your house was rendered? Is it looking a bit dull and dirty? If this sounds all too familiar, then it might be time to consider refreshing the façade of your property. Simply painting over the render might sound like the most obvious way to achieve this, but there’s slightly more to it than that. This blog unpacks how to go about painting over a property rendered in K Rend but not before explaining what K Rend is to help you identify the type of render on your property in case you’re not sure.

What is K Rend?

Due to its renown, K Rend is often confused as the umbrella term for all types of render when, in fact, it is a brand of render. Here at EWI Store, we stock K Rend Silicone K1 Monocouche Render and K Rend Silicone TC15 Topcoat. K Rend Silicone Render is water-repellent, polymer-modified and self-coloured, meaning it is available in a variety of colours so you can achieve your desired coloured finish.

How long does K Rend last?

While K Rend looks fantastic upon application, it can eventually look a bit grubby due to prolonged exposure to the elements. If you can see black, red or green streaks anywhere on the façade, this is a sign of biological growth and an even bigger sign that it simply needs a good clean; a simple jet wash should do the trick. It is vital to get rid of any biological growth before painting over the render as it can continue to grow under the paint, defeating the purpose of refreshing the face of the property. Nonetheless, too high pressurised water can cause damage to the surface of the property, so it is worth considering hiring a professional to clean it for you.

How can I paint over K Rend?

Once your property is clear of dirt and biological growth, it can be painted. However, while it is possible to paint over K Rend with standard masonry paint, it is advised to consult with a professional who can recommend more compatible paints as masonry paint can compromise the render system. For instance, our Silicone Paint works with our Silicone Render to offer advanced breathability, flexibility and durability, which can also be tinted to match the very same colour as the current façade or to absolutely any colour you like, including any RAL and NCS colour.

The verdict…

So, to answer the question at the beginning, you can paint over K Rend. However, some factors need to be considered before doing so, such as the condition of the render before painting (does it need a good clean?) and the type of paint to use over K Rend (which should be discussed with a professional). Once these factors have been considered, your property can be given a lovely refresh!

    Can You Paint Over Silicone Render?

    Have you had your Silicone Render for quite some time now? If so, you might be wondering how best to give it a little refresh. Here at EWI Store, we’re often asked how Silicone Render can be maintained to continue to exude a stand-out finish. Although Silicone Render has advanced self-cleaning properties, that doesn’t mean that it’s not completely susceptible to gathering dirt over time. To solve such, a gentle clean with a jet wash is perfect now and then however, houses that are likely to become dirty more easily – that is, those on busy roads or in highly-vegetated areas – may need to be painted over. That said, you might be wondering whether you can use standard masonry paint on top of Silicone Render. The simple answer is, while no one can stop you from doing so, it is highly recommended to use Silicone Paint instead. Keep reading to find out why.

    Why use Silicone Paint on top of Silicone Render?

    Silicone Render is a specialist, breathable render product ideal for application on external wall insulation systems where a breathable insulant, such as Mineral Wool, is being used. Therefore, while you technically can use standard masonry paint on top of Silicone Render, we recommend that you use Silicone Paint because it is also highly breathable. A standard masonry paint might not have such breathable properties which would completely nullify the render system’s ability to allow water vapour to pass through its surface, while a breathable Silicone Paint would work with the Silicone Render to continue to offer optimum performance.

    The best thing about our Silicone Paint is that it is available in thousands of colours. If your current render system is coloured and you’re afraid that you won’t find a colour to match, never fear – our Silicone Paints can be tinted to absolutely any shade! That way, not only will the Silicone Paint still cater to your taste, but it will also freshen up the entire façade of the property and extend its lifespan.

    How to apply Silicone Paint onto Silicone Render

    Before you apply Silicone Paint to your render, there are a few preparatory steps that must be taken to ensure a flawless finish. First, you’ll need to clear the render of any dirt or grime. If the walls have been painted previously, you’ll need to remove any flaking paint using either a jet washer or a wire brush. Also, be sure to apply tape to areas that need protection from the paint, such as window and door frames.

    Silicone Render is incredibly flexible and therefore highly unlikely to crack. However, if you notice any minor cracks, these too need to be filled.

    We recommend applying the paint using a standard brush and roller, starting at the top and working your way downwards to catch the paint as it drips and runs. Silicone Paint can be applied in multiple coats, so once the first is dry (after about 12 hours), you can go over it with as many coats as desired. However, beware that – if your render has a finer grain size – the more coats of Silicone Paint you apply, the less visible the grain size will become.

    So, if you’re looking to paint over your Silicone Render, look no further than Silicone Paint. Silicone Paint is the perfect solution for allowing your render system to continue to offer optimum performance, refresh the façade of your property and extend the façade’s lifespan.

      The Best Masonry Paint? Silicone Paint

      Are you interested in re-rendering your property and seeking high-quality masonry paint to coat the render for a fresh, modern finish? Then look no further than Silicone Paint! At EWI Store, we often receive enquiries about our Silicone Paint, the most common being “what is Silicone Paint?”, “what is Silicone Paint used for?” and “what’s the difference between Silicone Paint and Silicone Render?”. If you’re wondering the same, don’t worry – we’re going to cover everything you need to know about Silicone Paint right here, right now!

      What is Silicone Paint?

      Silicone Paint is a high-performance masonry paint that can be used for painting over either an existing Silicone Render to refresh the facade, or over our Mineral Render to seal the render. It is highly breathable, waterproof and resistant to environmental pollutants, making it perfect for homes in busy or humid environments where render alone may be susceptible to organic overgrowth. Silicone Paint is also available in thousands of colours, catering to every taste!

      What is the difference between Silicone Paint and Silicone Render?

      The names are self-explanatory; Silicone Paint is a masonry paint topcoat, while Silicone Render is a type of render finish. Their only similarity is that they both contain Silicone which provides numerous benefits, but we’ll come to those a bit later!

      While our thin-coat renders come in various grain sizes, ranging from 1mm to 3mm, our Silicone Paint is completely smooth, meaning it can be applied on top of an existing render without disrupting its texture.

      As with our Silicone Paint, our Silicone Render is hydrophobic, meaning it repels water, dirt and organic growth. However, even with all these capabilities, render can eventually look tired after so many years. That’s where Silicone Paint comes in; not only does it offer the render a decorative refresh, but also an extra layer of protection with its same hydrophobic properties, prolonging the render’s lifespan.

       

      Why use Silicone Paint?

      As we know, the ingress of water is detrimental to external wall insulation and render-only systems. In external wall insulation, the presence of water can reduce the system’s thermal capabilities and lead to freeze-thaw damage. In a render-only system, it can dampen the internal walls, especially in solid wall properties, damaging the overall render. Therefore, as part of external wall insulation or render-only systems, Silicone Paint is particularly beneficial; its breathability allows water to escape through the surface of the paint. Also, its vapour permeability makes it frostproof, meaning it won’t damage the surface of the paint.

      At EWI Store, we always suggest to our customers that our Mineral Render should be sealed with high-performance masonry paint like Silicone Paint. Mineral Render is our fastest-drying render, making it perfect for cold climates. However, its ingredients mean that, if exposed to the elements for too long, it can be susceptible to lime bloom. That’s why Silicone Paint is necessary as a topcoat; it prevents water from travelling through to the render and forming lime bloom.

      Silicone Paint can be matched to the Silicone Render underneath!

      If you’ve used one of our coloured Silicone Renders, then you can buy a Silicone Paint in the same colour to match! Here at EWI Store, we offer a same-day colour mixing service using our Render Colour Machine, which can tint Silicone Paint to thousands of colours. So, even if your render is not from EWI Pro, we can still match the colour to give it a refresh!

       

      As well as exteriors, Silicone Paint is great for interiors!

      Up to now, we’ve talked a lot about Silicone Paint can be used as a masonry paint as a render top coat to offer both a protective and decorative finish. However, as for exteriors, Silicone Paint is also great for interiors!

      Given that it’s waterproof, we’ve encountered many people who have used Silicone Paint in their bathrooms, making it perfect for combatting condensation on bathroom walls. Likewise, we’ve heard that people who have previously suffered from damp problems in their homes have used Silicone Paint as a deterrent, limiting the chances of such issues in future. One of our team members has even used Silicone Paint on his garden wall to prevent organic growth! In our opinion, all the above are great ways to utilise Silicone Paint.
