Walking down a street, you may spot many buildings. Each would have a varying appearance. Some may be modern, some traditional, some with exposed brick while some with wall rendering.
What is the difference between all of these houses? Why do some houses have a colored wall rendering, some have cement and some have none? The question is how people choose the right wall rendering material. Before you start the project of wall rendering, you need to take several steps as pre-preparation. The first obviously constitutes of you choosing the render material. This task is not as complex as it seems to be. You just need to know the properties of various render materials and you are all set to choose the one that suits your home the best. There are 6 types of material used for wall rendering:
- Cement Render: Cement wall rendering is the most durable type of render. When this is sealed with paint, it can give an amazing look to the wall as well as seal the cement rendering and make it damp proof and prevent penetration of water through the exterior walls. This type wall rendering is not recommended for old houses as its rigidity may prove to be a weakness and lead to the walls cracking easily.
- Polymer Render: This is a newer type in the rendering market. This is a white cement polymer which utilizes a silicone water repellent. This helps to keep away water from the surface of the walls. It can still let water vapor to pass through it to let the substrate beneath it breath with ease.
- Lime Render: This is traditionally known as ‘natural hydraulic render’ as it has been utilized for wall rendering since ages. This is the most breathable render product and is capable of expanding and contracting along with the surface of the wall it is coated on. Therefore, it is preferable for old brick and wooden homes.
- Monocouche Render: This type of render is for decorative purpose along with providing a protective layer over the wall against weather. The proof this material is that it does not require a base coat and it is available in a wide range of colors.
- Insulated Render: This is used exclusively for exterior wall insulation purposes. It can reduce the carbon footprints of the homeowner as it provides insulation and thus neither lets hot sun rays seep into the house nor lets in the chilly winter breeze, thus reducing the consumption of air conditioners.
- Acrylic Render: Acrylic render is mainly used as a finishing coat for other wall renderings. It contains materials formed from fragments and materials loosely compacted together facilitates providing a texture to the wall and thereby, help you achieve the appearance you aim for.
After you have decided the type of render you need for your wall rendering, you need to prepare the wall for rendering. If this is not done, the wall rendering process would not yield results as expected.
- Before you start, you need to ensure that the wall that has to be rendered is devoid of even the slightest presence of dirt, dust, oil, grease, paint, silicone, or any such material that can contaminate the wall rendering material.
- The whole wall should be scrubbed off to clear any remnants and traces of paint, mold, or and impurity.
- Then you need to treat the wall to prevent the growth of moth and unwanted plant sprouts.
- Then, a thin coat of lime should be applied which would facilitate bonding of the render coats that would be applied later on to the wall.
- The wall should be washed with fungicide to ensure there are no fungi developments on the wall.
- After all these preparations, you need to let the wall dry for 4 days and then you can start the process of wall rendering.
