Cement rendering might be the ideal solution for improving your house if your exterior walls are worn out. For instance, if your walls have become rough and unappealing due to weathering or their original colour has faded, you might benefit from this process. The cement render will change the overall appearance of your building, giving it a renewed look. You will also increase the real property value and even improve structural performance. If you are interested in this form of external wall improvement, consider these preparation steps for the rendering project.

Consider Your Rendering Goals

It is essential to evaluate your home and determine the desired outcome after the cement rendering. In most cases, homeowners want to change or enhance the appearance of the house. If this is your goal, you should think about the aesthetic effect that you would like to have at the end of the project. For instance, consider the ideal colour for your house.

Deciding on the colour at this stage will help you avoid the inconvenience of painting later. You should also determine if you would like a smooth or specially textured surface so that you can acquire appropriate tools. If you are planning on improving other aspects of your home such as thermal insulation or waterproofing, you might need to plan for the application of special cement mixes or thicker coats of render.

Inspect the Walls for Damage

Cement rendering is a process which is designed to conceal the general wear and tear of exterior walls. However, you must remember that significant damage cannot be easily covered. For instance, if your house has some large fissures, it will be difficult to fix it with the cement. Therefore, consider inspecting your walls thoroughly and identify the sections with damage before proceeding.

If you find problems, repair the wall before rendering. Otherwise, the render will not have stable support. As a result, the fresh material will deteriorate prematurely. Typically, you will only need to prepare the damaged area by removing loose material using a chisel. Then, seal the area with suitable patching material.

Think about Wall Dashing

Dash coats are advantageous when dealing with building materials with low absorbency. If a wall is not absorbent, it will be difficult to get the render to adhere for a prolonged period. The dash coat is a layer of a rich cement and water fluid which performs the role of a primer. Cover your walls with this material and your render will have an ideal surface for long-term adhesion.
