Reliable reinforcing mesh for crack-free walls and façades
When applying plaster or installing external wall insulation (EWI), structural movement and temperature fluctuations can cause unsightly cracks. Reinforcing mesh acts as a stabilising layer within the base coat, absorbing tension and distributing it evenly across the surface.
By embedding this durable fibreglass mesh into your render or plaster, you create a robust foundation that significantly extends the lifespan of your walls. It is an indispensable component for both professional builders and dedicated DIY enthusiasts aiming for flawless results.
Our range of reinforcing mesh and accessories
In our assortment, you will find high-quality products from the trusted manufacturer Dalsys, designed to meet various construction requirements. We offer universal reinforcing mesh, lightweight interior mesh (75 g/m²), and robust exterior mesh (115 g/m²) specifically tailored for EWI systems.
Depending on the scale of your project, you can choose from different roll sizes, including 10m², 15m², and large 50m² rolls, available in classic white or blue. Additionally, we provide pre-cut diagonal reinforcement pieces (available in packs of 10 or 100) to strengthen vulnerable areas around windows and doors.
How to choose the right reinforcing mesh for your project
Selecting the correct mesh depends entirely on your application area. For indoor plastering, a lighter mesh of 75 g/m² is usually sufficient to prevent hairline cracks. However, for exterior façades and external wall insulation systems, a heavier, alkali-resistant mesh is required to withstand harsh weather conditions and structural stress.
Diagonal reinforcement pieces are highly recommended for corners and reveals, as these areas are particularly prone to diagonal cracking. The prices for our reinforcing mesh range from approximately £23.99 to £66.99 (as of 2026), offering excellent value for both small repairs and large-scale renovations.
Frequently asked questions about reinforcing mesh
How do you properly install reinforcing mesh?
Apply a generous layer of base coat or adhesive to the wall, then press the mesh into the wet mortar using a trowel. Ensure that the mesh strips overlap by at least 10 centimetres to guarantee continuous structural support.
Why is reinforcing mesh necessary for EWI systems?
External wall insulation systems are subject to significant thermal expansion and contraction. The mesh absorbs these stresses, preventing the protective render from cracking and protecting the insulation boards beneath from moisture ingress.
Can I use interior mesh for exterior façades?
It is not recommended to use interior mesh for exterior applications. Exterior mesh is specifically designed to be heavier and more alkali-resistant to withstand the harsh chemicals in cement-based renders and changing weather conditions.
What is the purpose of diagonal reinforcement?
Diagonal reinforcement pieces are applied at a 45-degree angle at the corners of windows and doors. These specific areas experience concentrated stress, and the extra mesh layer effectively stops diagonal cracks from forming.
How do I cut the fibreglass mesh to size?
Fibreglass reinforcing mesh can be easily cut to your required dimensions using a standard utility knife or a sharp pair of scissors. Always measure twice and cut on a flat surface for a clean, straight edge.
Secure your surfaces with premium reinforcing mesh
Investing in the right reinforcing mesh is crucial for achieving smooth, long-lasting plaster and render finishes. Protect your walls against structural stress and ensure a professional result for every renovation project.
