Guide to Basic Home Rendering for Beginners

When we talk about rendering, we’re talking about coating your internal or external walls with cement render or a plaster finish. The latter is for both protection and aesthetic improvement. If you’ve been thinking about rendering your indoor or outdoor walls for the longest time, then you’ve come to the right place. In this article, we’re going to teach you the basics on how to apply home render onto your walls and give it an extra layer of beauty and protection.


1.) Rendering Basics

Cement-based renders perform several functions. These include improving fireproof rating, better waterproofing, and improved appearance through the use of coloured or textured renders. To get the best results, you need to make sure that the mix is suited to the background surface. It’s also vital that the mix is applied correctly to the right thickness and in the appropriate number of coats. Also, you should pay close attention to curing.


2.) Preparing the Surface to be Rendered

The surface for rendering must be clean and free from dirt, dust, grease, oil, silicone, paint, or any fragile material. Smooth and dense surfaces with low absorption rates such as metal window frame or concrete walls should be prepared with a “dash coat” before the actual render application. A dash coat is simply a strong mix of cement and water, which is applied to the surface to create an extra surface for the render to hold.


3.) Mixing the Render

First, choose which type of render finish you want. Once you’ve selected a render, refer to the chart in this link to determine the exact measurements and mix ratios to determine how much material you’ll need. Mix up enough render that you can use up in 30 to 40 minutes. If you’re planning to use oxides, follow the manufacturer’s guidelines.


4.) Applying the Render

Nail wooden battens with a thickness equal to the amount of render you will apply to guide you on the thickness. It will also give you a clean edge to work to. Start applying the first layer of rendering on to your wall using a steel float. Continue application until you’ve reached the desired thickness. Use a scraper to remove any excess render and make sure the surface is level.


Congratulations, you’ve successfully applied home render to your desired surface. Now all you have to do is let it dry and enjoy your newly rendered wall.
