When applying insulating plasters, long-term performance depends on more than just the plaster itself.
Diasen Polites 140 Reinforcing Mesh is designed to strengthen Diathonite plasters, helping to minimise cracking caused by substrate movement, thermal stresses and settlement.
Embedded within the plaster during application, it reinforces the system while maintaining excellent adhesion between layers.
Ideal for new builds, renovations and refurbishment projects, Polites 140 provides additional strength where it is needed most.
It is particularly important for Diathonite applications of 60mm or greater, ensuring the finished plaster remains durable and resistant to everyday stresses.
The mesh can also be used around vulnerable areas such as window and door openings, electrical boxes, conduits and other stress points where cracks are most likely to develop.
Manufactured from alkali-resistant fibreglass, the mesh will not rust or stain over time, making it a reliable reinforcement solution for both internal and external applications.
Its open 11mm x 11mm grid allows Diathonite plaster to pass through easily, creating a strong mechanical bond while remaining quick and straightforward to install.

Frequently Asked Questions:
What is Diasen Polites 140 Reinforcing Mesh used for?
It is used to reinforce Diathonite insulating plasters, helping to prevent cracking caused by substrate movement, settlement, curing and thermal expansion.
When should Polites 140 be installed?
The mesh should be embedded into the Diathonite plaster while the first layer is still wet.
For applications over 60mm thick, install the mesh halfway through the total plaster thickness before applying the remaining material.
Is reinforcing mesh always required?
It is recommended whenever Diathonite plaster is applied at 60mm or more.
It should also be used around high-stress areas such as window and door corners, electrical boxes and service penetrations, regardless of overall thickness.
Can it improve adhesion?
Yes. When embedded correctly, the mesh helps improve the mechanical bond of Diathonite plasters across a variety of substrates while reinforcing the plaster layer.
Will the mesh rust or stain the plaster?
No. Polites 140 is manufactured from alkali-resistant fibreglass, so it will not corrode or cause rust staining.
What size is each roll?
Each roll measures 1000mm wide by 50 metres long, making it suitable for both small and large insulation and rendering projects.
Can this mesh be used with other plasters?
Polites 140 has been specifically developed for use with Diathonite plasters and is recommended to achieve the intended reinforcement and performance of the Diasen system.
