What is Rendering?
Rendering has several meanings in the English language but in the building trade it comes from the word render meaning a coat of plaster or cement mortar applied to a surface. The process of house rendering therefore involves applying a protective and decorative layer to the exterior walls of a property. This practice has deep historical roots, with civilisations using various materials to shield their structures from the elements while adding artistic flair.
Why do people render houses?
People have been rendering houses with an exterior coating for many years. In it’s primitive form mud houses comes to mind but rendered buildings in many different styles and colours can be seen throughout the world dating back centuries.
The reason people render their houses is to add a layer of protection to the property from the elements but it is also applied for decorative reasons. It can brighten up a tired building or hide poor brick work and joins where a new extension meets the original building.
Special effects, different colours and patterns can also be created completely changing the look of a property.
Some modern rendering systems also help insulate a property thereby reducing the amount of fuel needed to keep it warm.
The journey from mud to more refined materials mirrors the evolution of construction itself. Rendering has become a signature element in various architectural styles, adapting to both cultural differences and climatic challenges.
Benefits of House Rendering:
Today house rendering offers many benefits, including protection against harsh weather conditions, decorative enhancements that boost kerb appeal, and potential energy efficiency improvements. It’s a versatile solution for modern homeowners, but there are so many render systems and colours available that choosing the right one can be quite a daunting task.
In this guide, we emphasise the importance of choosing the right rendering system. The decision is not just about protection; it’s about crafting a visual identity for your home. Whether it’s the timeless appeal of traditional renders or the innovation of modern systems, your choice will leave an indelible mark on your property.
Key Benefits Takeaway
Helps protect against the elements
It’s Decorative
Some renders can even insulate and help reduce fuel bills
Now lets take a look at what these different type of render systems are:
Types of Traditional Render Systems:
Traditional rendering systems have stood the test of time, offering a range of options to suit different needs. From the cost-effective Sand and Cement Render to the eco-friendly Clay Render, each type brings its own set of advantages. The 4 types of traditional render systems you are likely to come across which are:-
- Sand and Cement Render
- Clay Render
- Lime Render
- Pebbledash Render or Roughcast Render
Sand and Cement Render
Sand and Cement Render remains a popular choice in the construction industry due to its affordability. Its straightforward application process and budget-friendly materials make it a preferred option for various projects.
This form of rendering is the most traditional and cheapest. It is just a sand and cement mortar mix that it applied to the walls which is then troweled up flat. It is also sometimes called cement or flat render and left in it’s natural form will dry a cement grey colour. It can be left as it is but it is usually painted to a desired colour.
A colour pigment can be mixed into the mortar before application which will give it a coloured tint. Decorative coatings such as Tyrolean or Highbuild can also be applied to add some extra weather protection and decoration.
The Pros of Using Sand And Cement Render
- It’s effective.
- It’s economical
- It hides poor brick work
- It can be repaired easily
The Cons of Using Sand And Cement Render
- Not as weather resistant as some of the modern day renders.
- The finish is quite basic
- It has to be maintained
- It is prone to cracking with movement
- Needs to be painted
The cost of Pebbledash Render
Sand and Cement render is still an effective render system. It is also a budget-friendly option as the materials are cheaper than modern render systems. However labour costs are similar as it takes as long to do and it will also require continuous maintenance.
The cost of sand and cement render is estimated to be around £60 – £80 per m2, including labour and materials. Prices do vary as a lot depends upon what substrate it is going onto and the amount of preparation work is required. Other costs to consider are scaffold and the cost to remove and dispose of old render. If you want to know more about our Sand and Cement Render service you can do so here.
Clay Render
Clay being a natural material was one of the first to be used as a render exterior coating. It is more popular amongst developers creating eco friendly buildings as it has undergone very little processing. While Clay Render boasts environmental benefits, its aesthetic appeal should not be overlooked. The natural, earthen finish it provides is sought after by those aiming for both sustainability and a distinctive appearance.
Clay does however attract and hold water so is best suited for application over straw or timber. It also softens when water is applied which is ok for repairs but not so good for withstanding the British weather.
Whilst techniques such as adding straw or oils to the mix have been tried it is still quite a vulnerable render material that has a poor resistance to erosion.
The Pros of using Clay Render
- It’s environmentally friendly
- It can easily be repaired
- It’s cost effective
The Cons of using Clay Render
- Poor resistance to erosion
- Holds water
- The finish is quite basic
- High maintenance
Lime Render
Lime render is again another traditional render that is still used today. Being made with lime it has a huge advantage over traditional sand and cement render as it is flexible thereby reducing the risk of cracking making it particularly suitable for buildings prone to movement. It leaves an attractive traditional finish which will suit older properties or ones wanting a traditional style look. It is also eco friendly and durable but it takes longer to apply and the materials are more expensive therefore making it a lot more expensive than a sand and cement render.
The Pros of Using Lime Render
- It’s Flexible
- It’s breathable
- It has an attractive traditional look
- It’s relatively low maintenance
- It’s eco friendly
The Cons of Using Lime Render
- It is quite expensive
- A skilled application is needed
- It takes longer to do
- It requires quality aggregates
Pebbledash Render
There are two types of pebbledash render which are commonly known as dry dash or wet dash render systems. Dry Dash starts off life as a standard render application known as the receiver which is traditionally sand and cement or lime render. Whilst the render is still wet pebbles or small stones are thrown at it which create the pebbledash decorative finish.
Wet dash, or as it is sometimes called roughcast, is slightly different as the pebbles are first of all mixed with the render coat before it is applied.
Both systems are as good as each other from a durability point of view so it is really a matter or choice on the finish. The dry dash finish leaves a decorative pebble coating that can be left in it’s natural state with the pebbles showing or it can be painted. With the wet dash system the pebbles are already coated in the render mix which creates a more textured look rather than being able to see the pebbles so it is normally painted afterwards.
Pebbledash Render has experienced a resurgence in interest, thanks to modern rendering receivers. The elimination of traditional drawbacks, coupled with a wide variety of aggregates, has made it a cost-effective and visually appealing option.
The Pros of Using Pebbledash Render
- It’s weather resistant
- Done well it can look attractive
- It’s easy to repair
- It’s not very expensive
The Cons of Using Pebbledash Render
- Not as weather resistant as some of the modern day renders.
- The finish is basic
- It has to be maintained
- It is prone to cracking with movement
The cost of Pebbledash Render
Similar to traditional sand and cement render pebbledash render is a budget friendly render option. The cost is the same as a sand and cement render application, ie around £60 – £80 m2 just with the added cost of pebbles and/or chosen aggregate. Other costs to consider are scaffold and the cost to remove and dispose of old render. Pebbledash render is very effective but also requires a degree of maintenance. You can find out more about our pebbledash render service here.
Modern Render Systems
Advancements in technology means that traditional renders have come a long way. Special additives such as polymers, silicones and acrylics have created cost effective solutions to a variety of construction issues. Not only do these modern day renders deal with practical problems encountered with some traditional renders they also come in a wide range of colours and different finishes giving a homeowner so much more choice and flexibility. So lets have a look at these modern renders.
Coloured Render
Coloured render is really a general term used for the modern through coloured polymer renders that are available today. It is not a separate render system on it’s own but it gets a mention here as I am always asked if we do coloured render. Well the answer is yes but first of all you need to know what coloured render or through coloured render actually means.
As we mentioned above traditionally render had to be painted or at best you could add some colour into the mix which would give it a coloured tint. Modern day coloured render is what is known as through coloured which means that the colour pigment is added during the manufacturing process. When the render is mixed and applied to the walls it is a solid colour throughout the render rather than a coating. The benefits of this are that you can choose from a range of available colours and you will never have to paint it. That is unless you change your mind on the colour at a later date. The pigments added during manufacturing ensure a solid, lasting colour throughout the render, providing enduring vibrancy.
Key Features of Coloured Render
Colour Variety: Choose from an extensive range of colours.
No Painting Required: The colour remains steadfast without the need for subsequent painting.
Enduring Vibrancy: The pigment infusion guarantees enduring vibrancy.
The main modern render systems in the coloured render market are:
- Monocouche Render
- Silicone Render
- Acrylic Render
Lets take a look at each of them in more detail:-
