Rendering a wall of brick with concrete isn’t a simple task. It is an old procedure which has demonstrated its proficiency and utility throughout the years. Thus, despite the fact that it may look like a complex venture, experts suggest the use of cement rendering strategy, if you need to apply a solid complete on your brick or square walls. From the starting point, it is necessary to bring up that this technique is pertinently just for stone work walls, not for dry wall. In order to set up the concrete render, you could utilize a pre-blended mortar (you just need to include sand and water), or you can do it the old way, by utilizing cement, lime, concrete and water.


If you need to utilize the old style strategy, you need to blend one section cement, one section lime and six sections sharp sand. To get an appropriate render, you need to utilize a power blender and pour in the concrete, lime, sand and water. You need to blend these mixes for at least five minutes, ensuring you get a material with the consistency of pinnate margarine.

For wall rendering, you will need following items:


Materials: Fine sand and Concrete render.


Tools: Eye protector, Safety gloves, measuring tape, L-square, Carpentry pencil, Spirit level, Edge trowel to spread the concrete render, Solid blender to blend the concrete render, wheel barrow or construction buckets to transport the cement render.


Important Tip: Ensure the columns are plumb and Utilize the correct concrete render blend.

Step By Step Instructions To Render A Wall


  1. Setting up the walls: Prior to a building rendering, the walls should be analyzed, with repairs made to basic imperfections and any development stabilized, otherwise the finish of render is probably going to fall flat. Any new finish can be good only according to the wall behind it.


  1. Outside details: Outside details, for example, bargeboards should be removed regularly, along with water and soil channels and other outer subtle elements, for example, alert boxes. Any vents should be expanded, and some of the time window ledges must be broadened as well. Metal stop and edge dots are then connected around the window and entryway openings and corners (or the terraced property edges) to give clean edges to the render. The render framework would then be able to be connected.

  1. Insulation: Where outside wall insulation is being connected before the render coat, this is normally in the form of inflexible sheets or sections. The kind of settling should be chosen according to the wall category — which is either mechanically settled or glued on the walls.


  1. Foundation development: Render mesh of fabric is then connected over the insulation, added into the starting coat layer of render. This mesh works like a fortification against breaking. This is trailed by maybe a couple of thin layers of render, normally topcoat and primer.

  1. Building render: Distinctive preventive frameworks are developed with various layers, utilizing different types of insulation, including extended polystyrene (EPS), mineral fiber (Rock Fiber) and phenolic froth (more costly however better performance). Diverse kinds of render are utilized with outer wall insulation frameworks, contingent upon the application and the coveted get done with, including polymer cement, silicone and acrylic.


  1. Render finalization: Thin coat render frameworks are intended to be naturally colored so that they needn’t bother with painting. In the selection of colors, distinctive finishes are available, with exceptionally smooth to textured finish. If you have picked rendering that needs painting, ensure you pick a weatherproof paint for external use.
