What is Rendering?
Rendering is the process of applying a product to the exterior walls of a property, frequently to give a textured or smooth finish, which can have many advantages to brickwork but is often chosen for its aesthetics. Traditional render has been used for centuries across Europe and comprises of a sand and cement mixture.
Why Render a property?
Whilst other, perhaps newer, rendering types offer multiple advantages, the main purpose behind traditional sand and cement render is to give the property a particular appearance. Once applied, regardless of textured or smooth, the paint can be applied which enables the occupant to be contemporary or expressive beyond that of the original brick exterior.
Why have people moved away from Traditional Render?
Whilst a thick layer or sand and cement plus paint gives the property a beautiful appearance, this will not last as long as newer rendering types. As with most thick renders, traditional render will crack as the building expands and contracts with the temperature, once water gets in these cracks it can expand them and eventually seperate the render from the wall. With the paint applied after the render was originally applied to the wall, any cracks in the paint will show the grey plaster beneath which is not the same of coloured render available to monocouche, acrylic or silicone render systems. Also, traditional render is not a permeable material, which means that whilst keeping some heat in the building, it does not allow the property to breathe which has been known to cause internal damp if not ventilated properly.
What is the cost Traditional Render?
All that being said, traditional render is still the cheapest rendering type available which means for those looking to improve the aesthetics of their building on a budget this is a possibility. It is hard to give a quote on the cost of traditional render without first evaluating the property, but as a gauge it costs around £65/m2.
