General mesh installation within base coat - General Renders
- Overlap the mesh a minimum of 100 mm to all horizontal and vertical edges.
- TV10 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.
NOTE: When using two layers of mesh, place the appropriate primary layer of mesh into the render behind the TV10 mesh and butt the joints do not overlap). Embed the TV10 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 TV10 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.
Please also refer to the mesh application details – B2 & B3.
Mesh installation around openings - General Renders
- Reinforce the corners with TV10 mesh to all openings - minimum dimension 300 x 300mm before applying the main TV10 reinforcing mesh.
- All mesh to be embedded within the render and not bonded to the substrate surface. Please also refer to the mesh application details – B1 & B3.
Mesh position within the base coat - General Renders
TV10 mesh is 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.
NOTE: When using two layers of mesh, place the appropriate primary layer of mesh into the render behind the TV10 mesh and butt the joints (do not overlap). Embed the TV10 standard 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 TV10 mesh and the additional layers of mesh never meet in the same location but are positioned a minimum of 200mm apart from each other.
CAUTIONARY NOTE: (This applies to most render applications) Due to shrinkage differentials, avoid applying a thin base coat and
a thicker top coat application as the shrinkage values of a thicker top coat could cause the render to delaminate from the base coat.
The same effect is also caused by applying a very hard render over a softer base coat.
Please refer to additional mesh application details – B1 & B2.
