Install 10mm or 12mm board as per the installation instructions using butt joints with SHERA PU sealant to prevent water penetration through the joints. 

In the image below you can see the joint between the SHERA fibre cement boards prior to rendering.

Apply SHERA cement bonding is applied to the surface of the boards to prevent excessive dust and improve the bonding of the render. This is optional but suggested to eliminate dust and to reduce cleaning effort at the construction site.
