Rendering Exterior Walls
Introduction to rendering exterior walls & outside walls
One of the best methods to increase the value of your home is to make exterior improvements and changes. The least expensive way to do the same is with a fresh render. Your home's exterior will be the first thing prospective buyers or guests notice.
Therefore, it is crucial to ensure that it has curb appeal, particularly if the current exterior is dilapidated or composed of a variety of mismatched materials.
A house's façade can be rendered to make it more modern, fashionable, and energy-efficient. Rendering may significantly raise the value of your property, whether you are planning to sell or are creating the ideal family home.
Study up on outside wall rendering. The technique of applying external wall coverings with render to safeguard the building's foundational blocks or bricks is known as rendering exterior walls. To prevent erosion or cracks, the render surface is typically coated with a thin layer of paint or another wall treatment.

If your building's outside walls are rendered, you must maintain the wall covering properly to avoid water intrusion and moisture seeping through the render finish into your home.
Is rendering external walls worth it?
Even if you live in a more modern home, there are plenty of solid reasons to consider rendering your property.
It is not inexpensive for your house, though, particularly if you own a big property. Think carefully about the kind of rendering you want to use and select the one that best suits your needs.
Additionally, since this is an investment that will remain on your wall for a number of years, carefully consider what you want to achieve and whether you should insulate at the same time. Additionally, replacing or removing it will be costly.
Why do You need to Render the Exterior Walls of Your House?
Most homes eventually require a facelift once or twice in their lives. For better property protection, most structures require a waterproof render treatment if the brickwork is eroded or damaged.
Weather Resistance
Making your home's outside walls water-resistant and lowering maintenance costs is the most popular justification for rendering. Because the bricks are porous, they function as a damp sponge, allowing water to seep through the cavity wall and cause damp penetration. When water seeps into the outer layer of bricks, the surface crumbles and ice crystals form as a result of cold conditions. Your home's bricks can be effectively sealed off from ice and water damage by rendering them.
Insulation
Insulation helps buildings without cavity walls. However, cavity wall insulation is not an option for modern dwellings. There is a slight insulating effect in modern homes. Render can act as insulation in these circumstances. It should come as no surprise that installation costs are higher than those of cavity wall insulation, but it works incredibly well, and you need to have unbroken waterproof pointing in your brickwork. The house is made more insulated by using external wall insulation. Because acrylic and polymer renders have a better insulation rating than cement renders, you can use them in addition to insulation renders. It is sense to consider external wall insulation if you are paying for the labor costs of scaffolding and repairing existing renders.
Damp & Mould
Porous surfaces can behave as a damp sponge, increasing the likelihood of mold and moisture infestation in your house. The structural integrity of the house is harmed by dampness, which also exacerbates a number of health problems. Additionally, it has the potential to ruin furnishings and furniture. Using a smooth, high-quality finish render keeps mold, moisture, and penetration out of your structure. Usually, damp may be kept out of the house after the second coat of render. It won't, however, assist in getting rid of the mold and moisture that are now present in your house. Therefore, among other issues, it is up to you to decide how to handle condensation, rising damp, and penetration damp.
Aesthetics
Rendering a house is more vital than ever for numerous practical reasons, but the main one is to make it seem better. In addition to repairing damaged brickwork, rendering may add color to a run-down wall and revitalize the entire structure. Some properties may be a complete mess of brick materials or have unsightly damage from years of exposure. Applying render gives you a smooth finish and completely alters their appearance. Smooth white render is the norm these days. Additionally, you should think about re-rendering if your render is old, cracked, or fatigued. It entails removing the old render and beginning over on the exposed wall. There can be masonry paint in your brickworks. Installing render would be a fantastic solution to repaint every few years in this situation. When the entire wall is rendered, the house looks better, has more curb appeal, and is therefore more desirable to purchase.
Types of Rendering Exterior Walls & Outside Walls
There are many different types of exterior rendering, including:
1. Sand and Cement Rendering
This type of render, which is the most popular, is a mixture of cement, sand, and water that is applied as a topcoat, scratch coat, and decorative paint coat.
The render is widely accessible and well-liked by builders. In addition, cement rendering is stronger and considerably tougher than lime rendering. Compared to the majority of other rendering materials, it is essentially less expensive. However, drying takes a long time. Furthermore, metal is readily and quickly shattered if misused.

2. Acrylic Rendering
Similar to cement rendering, acrylic rendering adds a plastic substance called acrylic to the render mix, giving the render more flexibility. It works well for a variety of external rendering tasks. It comes in a variety of colors and textures.
Brick, polystyrene, cement, pre-existing render, and painted walls all work well with acrylic rendering. It offers a smooth finish, takes less application, and dries more quickly. In addition, it is more resilient to cracking than cement rendering. It also provides defense against water damage and UV radiation.
3. Monocouche Rendering
This kind of rendering uses a dry powdered material called monocouche with a colored pigment. It gives the textile breathability.
For quicker installation, these renderings are done in a single layer. Furthermore, since the render is already colored, decorating doesn’t require painting. The most popular monocouche renderings, including Parex, Weber, and K Rend, are accessible.
In order to get a rusted impression, this render scraped it and provided a powdery finish.Existing concrete, cement, brick substrates, and polystyrene can all be rendered with monocouche. It is incredibly flexible, weather-resistant, long-lasting (up to 10 years), and easy to use.
4. Polymer Rendering
Applying a cement render to every surface creates a strong bond. When cement rendering or acrylic rendering would not work, a very sticky polymer is applied to the render.
Furthermore, since polymer render eliminates the need for additional waterproofing, it is advised for damp portions of a building.
Because it is weather-resistant, it is ideal for rendering exterior walls. For a number of exterior rendering tasks, it is perfect. These materials also lessen wear and strain on the property, are lightweight, adhere to the wall better, and don’t break.
Other forms of external rendering can be used in addition to the one described above, including:
