The Most Waterproof Render?

Modern technology has enabled us to manufacture highly waterproof renders, and the demand for them is high.

We’ve spoken a lot about how old-fashioned sand and cement renders are renowned for causing problems with damp – they’re essentially an accident waiting to happen. The render itself eventually becomes waterlogged and full of cracks. This will cause you never-ending problems, and in some cases structural issues.

This means that when you actually get around to re-rendering your property, you’ll likely want to upgrade to the strong stuff that won’t crack and is highly waterproof!

For areas that are continuously wet and damp, careful consideration should go into which modern render you choose. If your existing render is ineffective, these kind of wet conditions can have a visibly negative effect on the building and appearance of the render. Often, excessive organic growth accumulates on the surface of the render and mouldy damp patches develop on the internal walls.

For these kinds of situations, we have the perfect render!

The most waterproof render? 

As render specialists, we recognise that waterproof properties are an absolute must when it comes to render – especially in the UK! Because of this, we have created two unique and high-performance products that are unmatched in the render market.

Nano Drex Silicone Render (EWI-077)

This product is our most advanced render formula. It is highly breathable, flexible, and hydrophobic (waterproof). This means that it has self-cleaning capabilities to ensure the fresh finish of your property is maintained for longer.

If you are looking for the highest-performance render available on the market, the Nano-Drex offers unmatched benefits. You can read more about the benefits of Nano Drex in our recent blog, which is aimed at helping you choose your perfect silicone render!

Premium Bio Silicone Render (EWI-076)

The Premium Bio Silicone Render is designed specifically with hydrophobic properties in mind. It is incredibly waterproof. This means that water is repelled from the surface of the render, instead of absorbed into the material. When water hits the surface, it forms droplets that roll straight off.

This significantly reduces the formation of organic growth and problems with damp over the lifespan of the render. In turn, this keeps it looking fresh and clean for longer. To further support the prevention of damp, Premium Bio has also been manufactured to be very flexible, crack resistant and impact resistant. Therefore, it’s far less likely to form cracks that will enable the passing of water through the walls.

As mentioned, silicone-based renders (such as our Premium Bio Silicone and our classic Silicone) are known for being both waterproof and breathable. Breathability is an important factor for ensuring that moisture can easily escape from the building. Water vapour can build up within a building, and so a balance between good ventilation and permeable building materials must be struck. This ensures that damp does not become a problem.

Premium Bio Silicone Render comes in a variety of grain sizes to achieve the texture that you prefer, and it can also be tinted to create any shade of colour.

How to Install Waterproof Render?

A waterproof render needs to pair with a waterproof, breathable and high strength basecoat. This means that our Premium Basecoat is the best thing for the job.

The Premium Basecoat is trowelled onto the substrate to form the reinforcement layer, with a Fibreglass Mesh embedded within it. The Premium Bio Silicone Render is then applied on top once the basecoat has set.
