In simple terms, external rendering is the process of applying a coating to the walls of a building, in doing so this provides a protective coating which aids in preventing rain damage and will also act as a decorative feature to enhance the external appearance of a building. Our Cardiff plasters are the experts of exterior rendering and certainly enjoy giving as much of their knowledge as possible. So do feel free to ask as many questions before we begin the rendering process Our plasters will give you a range of rendering options, all of which will give the exterior of your property a completely different look.
- This is a render compound that is made using lime putty, and it provides two big advantages of being both flexible and breathable. This style of render is suited to buildings that may experience a lot of movement, such as older buildings made using timber frames.
- Lime render is essentially acting like a sponge on the walls, so rather than it blocking and creating a barrier for rain, it will actually suck it up like a sponge. Then, due to its levels of breathability, the moisture will begin to evaporate quite quickly, so if you are having that thought of “were does all the water go?” Do not fear, it will evaporate.
- This type of render is typically made using OPC (Old Portland Cement) are you will find this is much, much stronger than lime render and this render choice is usually painted on. Similar to choice of lime rendering, when choosing Sand and Cement rendering, waterproofing is also an issue. So usually a finishing coat of paint will be added to give that extra protection and of course, for decoration purposes.
- There is a magnitude of advantages that come with using this style of render such as it being strong and hard, cheap to use, easy application (if you are a plasterer of course) and relatively quick curing.
- Funnily enough, clay was actually the first material that was used in the world of plaster and render, and in recent times is definitely still highly regarded due to its environmental credentials. Of course, it is easy to produce as well and can usually be locally sourced. In most cases though, to ensure you are using a render that has consistent qualities, our recommendation is to source commercial clay render.
- Clay render also has a range of advantages with the most prominent one being the environmentally friendly aspect that is highly regarded in this day in age. Another fantastic advantage is that is extremely easy to rework and repair, which is a truly huge benefit, our plasterers are perfectionists therefore being able to rework a material when you are not completely happy with the finish, makes clay rendering a big thumbs up from them. Last but not least, the other advantage is the cost efficiency aspect, so if you’re trying to save those pennies, have you even considered clay render?
