When you buy an older home as an investment, it may need a certain amount of renovations to make it both liveable and sustainable. The walls may be largely untreated and may require both a layer of insulation and some cement render. If you're looking at this type of work on your property, what do you need to think about?
Before you take any action, ensure that you have permission to do so. You may or may not require permission based on the zoning rules in your town, and you want to check with the home owners association (if applicable) to see what regulations may dictate.
You will also want to fit in with the general vibe of your neighbourhood if you intend to sell this property for commercial gain. A prospective owner is likely to be more interested in the home if it fits in with the surrounding properties. In other words, make sure it doesn't stick out like a sore thumb when it's finished.
Rendering – Step-By-Step
Choose a solution before you begin to prepare. There are many different types of render, some of which come with a form of insulation built-in. Alternatively, you may choose to attach your insulation to the exterior wall first before applying the type of render designed for this situation.
You will need to carefully prepare all of the walls before render can be applied. In many respects, this is similar to painting, and you will need to thoroughly cover those window or door sills and other parts of the home before you proceed. You may need to remove any downpipes, guttering, external alarms and other attachments so that you can continue without any issue.
If you decide to fit installation boards to the walls, then you need to fix them carefully before attaching the fabric mesh. The fabric will help to keep the render in place once it is applied and will form a solid foundation.
You will certainly need to master the technique of applying render. It may look relatively straightforward in the hands of a professional, but if you learn as you go then it may take you a long time to finish the work, and you may have to go over it again to patch up.
Once you have applied the render, you may decide to add a layer of weatherproof paint or leave it as it is, if you're happy with the finish.
