PREPARING UNEVEN SURFACES

In case of uneven surfaces or damp walls we recommend using anti-rot treated battening. 

Ensure ventilation behind the cladding by leaving gaps in the battening. Batten spacing should be at 25 to 40 cm centres. Battens should be fixed horizontally for vertical installations of the PVC panels. Make sure battens are flat and level, packing out where necessary on uneven walls so that when fixed the cladding does not deform due to curvature of the battens.

The PVC panels can be mechanically fixed to the battens using one of the following methods:

Nailing/screws: use non corrosive nails/screws. Apply nails evenly and level in the panel lip. Be careful not to hit the panel with the hammer.

Stapling: use non corrosive staples at least 14mm long.
