● Place long edge of sheets across the supports.
● Allow 2-3mm expansion gap on all sheet edges and if required, use some form of elastic sealer to fill the gap — the gap may have to be widened to allow for the gap filler. 
● When nailing or screwing the sheets, it is essential to fix to avoid movement. When countersinking the fixings through the overlay paper it will be necessary to fill these with epoxy filler and smooth off to give good finish and limit moisture uptake.
● To avoid staining from fasteners use hot-dipped galvanised, stainless or alloy fasteners.
● Cut edges should be resealed using acrylic paint which helps keep moisture out and minimises distortion that can be caused by expansion around sheet perimeters. The factory’s cut edges are coated with a water repellent coating.
● Use release agent before use and reuse to ensure clean release from concrete and to minimise hydration staining and grain raising.
● Take care to avoid vibrator contact as much as possible to keep face intact.
● When storing sheets lay flat with support of bearers.
