The cost of having your house rendered can vary depending upon several factors. First, the type of render you opt to have installed will make a difference in the overall cost of the project. Secondly, the size of your property will dictate the amount of material required, so naturally the larger the property the more expensive it will be.
We always recommend getting a quotation from at least 3 installers prior to going ahead. This way you can compare prices and find an installer that you trust. If you need help finding trustworthy installers in your area, give us a call and we can put you in touch! We have a database of installers who have undergone our rigorous training course and who we recommend to other customers like you.
One of the biggest cost-conscious decisions you will need to make is the choice of render. We’re going to talk you through a range of options and explain the benefits of each.
Sand and Cement Render
Sand and cement render is the cheapest option available, and as such it’s possibly one of the worst choices in terms of longevity. Sand and cement render is an incredibly inflexible material that cannot withstand the slight fluctuations that a building naturally makes because it’s applied in such a thick layer.
The second issue with sand and cement render is that it’s not breathable and can very easily become waterlogged once cracked. Essentially what this means is that once water gets into the material it will struggle to evaporate out and will eventually cause damage (i.e. blown render or penetrating damp on the internal walls).
Monocouche render is the next step up from sand and cement, costing around £12 bag. Rather than coming as separate ingredients that the installer needs to mix on-site (i.e. the sand and cement), the monocouche render comes readily prepared in one bag, all it needs is mixing with water.
The key benefit of the monocouche is that it’s through-coloured so there’s no need to paint it afterwards. Unlike sand and cement render, which is perfectly smooth, monocouche provides a natural stone-effect finish as it is scratched back to create a textured effect.
One downside to the monocouche render is that again it’s applied in a thick layer, which makes it more likely to crack. Modern technology has enabled us to produce breathable monocouche renders, however once the render cracks it still becomes very difficult to regulate the movement of moisture in and out of the substrate.
Acrylic render is somewhat different from the previously mentioned renders, as it is classed as a ‘thin coat render.’ Acrylic is the cheapest of our entire range of thin coat renders, coming in at just £29.97 ex. VAT per bucket. The render itself is applied in a very thin layer of 1-3mm (depending upon the grain size), on top of a reinforced basecoat which is around 6mm thick. This means that the maximum total thickness of the render system is 9mm – far less than your average 15mm+ for sand and cement. The thinness of the render means that it is far more flexible and able to compensate for any movements within the underlying substrate, so the chance of cracking is massively reduced. Thin coat renders come ready to use straight out of the bucket; they are through-coloured in a range of shades (much like paint) and are applied by trowel.
Acrylic render is a non-breathable thin coat render, but out of all the thin coat renders it is the most impact resistant.
Once you start getting into the ‘silicones’ category, you’ll notice that prices begin to rise due to its greater performance. Silicone Silicate is a hybrid silicone thin coat render, costing £52.45 ex. VAT per bucket. This is our best value thin coat render due to the performance it offers at the price point it comes in at.
Much like the acrylic, it comes ready to use in a tub – pre-coloured and pre-mixed. It’s highly versatile but also great value, offering the key benefit of breathability. While it does possess less self-cleaning capabilities than our full silicone render and our Premium Bio Silicone Render, Silicone Silicate does offer a long-lasting, aesthetically pleasing finish.
If you want top-quality and top performance, then you can’t go wrong with our Silicone Render – £57.23 ex. VAT. People tend to pay more for the full silicone render as it is a notoriously high-performance render. It offers breathability, crack resistance and self-cleaning capabilities which provide the reassurance of a long-lasting finish.
Buyers commonly assume that ‘K Rend’ is the only silicone render product, when it’s just one brand of silicone render. Don’t fall into that trap, as there are plenty of other manufacturers of silicone render on the market who all offer a range of finishes and colour choices.
Premium Bio Silicone Render
The Premium Bio Silicone Render is our top of the line, breathable thin coat render, offering advanced self-cleaning capabilities, enhanced impact resistance and increased UV protection. This means that it provides a long-lasting, crack-resistant finish that will remain vibrant in colour for years to come. Because the Premium Bio offers absolutely everything, it’s our most expensive option, coming in at £70.41 ex. VAT per bucket.
