Parex® 355 AVU Reinforcing Mesh
A green coloured glass fibre mesh fabric combined with specially designed surface treatments that can be used in a wide range of PAREXTHERM and PAREXDIRECT render applications. For ease of identification the 355 AVU mesh is coloured green and has the ‘PAREX’ name and logo throughout the mesh.
- High mechanical strength.
- Excellent dimensional stability.
- Compatible with all PAREXTHERM and PAREXDIRECT render systems.
Usage
The 355 AVU mesh is mainly used as one component of the Parex® range of external thermal and direct render systems. A high quality synthetic coating on the glass yarn protects the mesh against alkaline influences from the adhesives and base coat materials that are used.Advantages
- High mechanical strength.
- Excellent dimensional stability.
- Compatible with all PAREXTHERM and PAREXDIRECT render systems.

Application
APPLICATION
355 AVU mesh has been specifically designed for use in the application of MAITE when used as part of a PAREXTHERM or PAREXDIRECT render system. Consult the specific product data sheets for each render system for application guidance.
General mesh installation within base coat
- Overlap the mesh a minimum of 100mm to all horizontal and vertical edges.
- 355 AVU reinforcing mesh encapsulated within the render. When additional reinforcement is required, use a primary layer of the following meshes.
- Heavy duty applications - 358.10 Heavy Duty Mesh.
- High impact applications - 358.14 High Impact Mesh.
- Ultra high impact applications - 358.20 Ultra High
- Impact Mesh. Do not apply the mesh directly to the substrate and render over.
- For high absorption substrates e.g. lightweight block, terracotta, brickwork etc, or low absorption substrates e.g. dense concrete, smooth engineering bricks etc, apply a layer of MICRO GOBETIS 3000. For full guidance on which substrates this is required on, always refer to the Parex project specification.
Mesh installation around openings
- Reinforce the corners with 355 AVU reinforcing mesh to all openings - minimum dimension 300 x 300 mm before applying the main 355 AVU reinforcing mesh.
NOTE: When using two layers of mesh, place the appropriate primary layer of mesh into the render behind the 355 AVU reinforcing mesh and butt the joints (do not overlap). Embed the 355 AVU reinforcing mesh over the primary mesh and overlap the joints a minimum of 100 mm in all situations. Ensure the mesh is fully embedded within the render coat. If an ashlar cut is required, ensure the mesh is placed sufficiently deep enough to avoid showing through the back face of the ashlar cut. (Additional thickness of render will be required for these applications).
IMPORTANT NOTE: To provide the correct level of reinforcement benefit, always ensure the joints of the 355 AVU reinforcing mesh and the additional layers of mesh never meet in the same location but are positioned a minimum of 200 mm apart from each other.
Mesh installation around openings

Mesh position within the base coat
355 AVU reinforcing mesh encapsulated within the render. When additional reinforcement is required, use a primary layer of the following meshes. Heavy duty applications - 358.10 Heavy Duty Mesh. High impact applications - 358.14 High Impact Mesh. Ultra high impact applications - 358.20 Ultra High Impact Mesh. Do not apply the mesh directly to the substrate and render over.
