Having an external wall of your property rendered simply means the repair and maintenance of any damaged exterior surfaces. Professional renderers check for cracks, peeling, flaking and damp; then aim to restore the wall and improve the quality of the surface. Rendering an external wall has many advantages over and above the appearance, rendering can reduce heat loss and help make the surface more weatherproof and durable, even improving resistance to mould and algae. There are a number of wall render options available from contractors, and many types of rendering can be found under a number of alternative names and brands. The costs of rendering an entire property can prove to be an expensive home improvement project, but rendering is as an investment that improves your standard of living and adds value to your property.
It is not advisable to attempt to render your own wall, unless you are a professional. The rendering materials used and the techniques applied can take years of skill to develop and perfect, plus there are endless possibilities to get it wrong, which most likely would! The rendering process involves the preparation of the surface to ensure it is dust free with no loose or flaky residue, then the surface is damped down and primed with a bonding solution before applying a quality high polymer render which needs mixed with clean water to make the consistency to suit the surface to be coated. Once beads have been fixed start, the render can be trowelled onto the wall with the thickness depending on how bad the substrate is, but up to a maximum of 12mm. Once the first base coat is covered, the area must be prepared for the second pass of render, which is best applied before first coat totally dries out. This second pass is a skimming coat to tidy the appearance up. When the second render pass dries, the job is ready to be finished off using a plasterers sponge to take out any high points or voids. When cured the new rendered surface is then ready for any decorative coating.
