No matter how solid a building material is, over time it’ll yield to the elements. When it comes to wall rendering it may be a case of too much sunshine or a costly mistake in the application process, but in truth, it cracks just because it cracks.

In order to repair render cracks, you’d have to start with a removal of damaged or cracked render. You’ll have to remove all the render or just a small section depending on the area you’re working on. If you’re able to clean all of the existing render as well as the paint over it all (both old and new), then removing a small section would work better as it makes it look neat and redone. Upon the removal of the existing render, the next important step would be to remove all loose material as well. Once done, you can then leave for up to 2 days to allow any trapped moisture to come out. Unfortunately, if the rains you’d have to wait till that dries too before you proceed.

Once dried, you can buy a pre-prepared render mix which already contains cement, lime and sand. Mix a 20kg bag with 4 litres of water (or check the product instructions and follow strictly), the mix to a fine consistency. Render is quick to dry, so you’d want to apply within 30 minutes of mixing. Make use of a trowel to apply the render on the affected spots and blend with the surrounding area.

Wall rendering is basically a process which involves the application of sand, cement or polymer covering to a home’s exterior in such a way that enhances its look while also offering an improved stability. The process is a perfect solution for several exterior concerns mainly due to the support its able to provide. It’s highly beneficial for older homes whose walls may suffer from poor quality because of wear over time, while it’s also greatly advantageous for newer homes as it increases their stability while also enhancing their visual appeal.

Knowing how to apply render is a great skill to have with your home’s upkeep in mind. The project can be done quite easily by any competent and confident DIYer. However if you lack any of those attributes, then we’d recommend you get in touch with a reliable professional for help. In this article, we’ll take you through the wall rendering process.

✓ Prepare the walls. This involves examining the wall, repairing any structural defects as well as stabilizing any movements to prevent the render finish from failing.

✓ External details. This includes the removal of bargeboards, rainwater, soil pipes, alarm boxes and all other external details.

✓ Insulation. In the event whereby external wall insulation is to be fitted, this is the stage to do so.

✓ Developing a foundation for the render to fix to. Apply a render mesh over the insulation, bedded into the first base coat layer of render.

✓ Building up the render.

✓ Render finishes. There are a wide range of colour options as well as various finishes available from very smooth to textured. However, you should note that thin coat render systems are usually designed to be self coloured.

✓ Final finishes. This involves the re-application of the external rainwater, soil pipes and the other external details.

Rendering a house’s external walls is one of the cheapest and most effective ways by which a building can be made waterproof and also good looking. If you’re thinking about rendering your house, figuring out the cost of completion is usually one of the most important things you’ll have to consider before you proceed and if you don’t know where to start, finding an experienced tradesperson who possesses several years of experience as well as the ability to overcome the different issues that he may be faced with while on the project is paramount. If you’re able to get one, however, you should know that they rarely come cheap.

When trying to determine the accurate house rendering cost estimate , a tradesperson will put into consideration a great number of factors. Even at that, a rough estimate still requires both skills and expertise to be able to take into account all the necessary factors. In general, a typical 3 bedroom home in the UK will cost within the range of £4000 to about £5500 for a complete render job on the outside and covering from top to bottom.

Usually, the most important factor which play the biggest role when determining rendering costs is the area that’s going to be covered by the render mix. Professional contractors will provide a quote based on the rendering costs per square metre. Below are some rough estimates of rendering costs of properties depending on their size (without VAT).

✓ For a small mid terrace house of about 40 to 50 square metre, the total rendering cost estimate is £3000 to £4000.

✓ For a large mid terrace house of about 70 to 180 square metre, the total rendering cost estimate is £3000 to £5000.

✓ For a three bedroom detached house of about 100 to 160 square metre, the total rendering cost estimate is £4000 to £5500.

Rendering is an external wall’s plastered finish which provides a smooth finish while also protecting the brickwork from the elements like rain, snow and the likes. The traditional rendering is normally applied in two or three coats which enables it to be more resistant to surface cracks. In modern times, the finishes are largely different from the grey pebble dash of post war housing. Today, we now have a plethora of specialist products to pick from such as through-coloured silicone renders as well as one coat renders. The types of renders include the following:

✓ Cement renders. These are the common option that are usually mixed on site and used in a number of applications, then painted when dried. There’s a need to paint this type of render regularly to keep them looking great.

✓ Polymer renders. These are pre mixed and mostly pre coloured (usually with through colouring).

✓ Through-coloured products. These rendered do not need to be painted as the pigment is already added in the manufacturing process to colour the whole render.

✓ Lime renders. These are superior to cement as they’re less likely to trap moisture in the brickwork and also more good looking. However, they’re generally more costly and more difficult to apply.

Overall, rendering on a house provides several benefits. Not only is it able to protect your brickwork against the elements like the rain and wind, but it can also make the building more efficient. Being fully aware that about 30 percent of the energy used in heating a home is lost via the external walls, making use of a product such as acrylic insulated render is a smart approach to improve your home’s energy efficiency without affecting your interior living space.
