When it comes to achieving a durable and flawless rendered finish, using the right techniques and materials is essential. At JM & MJ Solid Plastering, we understand that professional rendering in Brisbane requires more than just experience, it requires attention to detail and the correct application of systems like reinforcement mesh. In this article, we explore the essential role of mesh in rendering, why it’s used, and how it helps prevent cracking in both residential and commercial rendering projects.
What Is Rendering?
Rendering involves applying sand cement, polymer modified products and acrylic texture coatings to external walls. These protective layers serve as both functional and aesthetic purposes: it improves curb appeal, protects your building from the elements, and provides a smooth finish. However, not all rendering is equal. Without the correct preparation, reinforcement or system, even the best products can crack, especially in Brisbane’s humid and shifting climate.
Why Does Render Crack?
Render can crack for several reasons, including but not limited to:
Building movement and settling
Shrinkage during curing
Temperature fluctuations
Improper material mixing
Poor weather during application
Cracks not only affect the appearance of your home but also allow water ingress, which can lead to mould, mildew, or render delamination over time.
How Mesh Prevents Cracking in Rendered Walls
This is where reinforcement mesh comes in. A thin but strong material (often made from fibreglass), mesh is embedded into the render to strengthen the finish and prevent cracking.
1. Even Distribution of Stress
Buildings naturally move over time due to shifting foundations, wind, and thermal expansion. Mesh absorbs and distributes these stresses evenly across the rendered surface, reducing the chance of stress cracks, particularly in high movement zones.
2. Effective Crack Prevention
The key benefit of using mesh in rendering is its ability to prevent cracks from forming or spreading. Mesh provides a flexible framework that allows the render to remain intact even when the underlying structure shifts slightly.
3. Flexibility in Harsh Climates
Brisbane’s hot and humid conditions can cause expansion and contraction in external walls. Reinforcement mesh adds flexibility to the render, allowing it to move with the structure rather than resist it, minimising cracking over time.
4. Enhanced Durability and Longevity
When you invest in rendering, you want a finish that lasts. Mesh significantly extends the life of your render by strengthening it against everyday wear, environmental pressures, and moisture.
5. Prevents Render Delamination
Delamination occurs when the render begins to peel or detach from the wall surface. Mesh helps create a stronger bond between the render and substrate, reducing the risk of separation and failure over time.
When Should Mesh Be Used in Rendering?
At JM & MJ Solid Plastering, we assess each project to determine whether mesh is required depending on the substrate and desired finish. We follow the specifications outlined by our supplier, Rockcote, to ensure long lasting, compliant finishes, with a warranty.
Whether you're renovating an older home or building a new one, incorporating mesh in your rendering system when required is a smart investment in both durability and appearance.
