● 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. The veneers are bonded with marine type glue, which ensures they will not separate under wet conditions.
● Use release agent before use andre use 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 and in so doing extend the life, to give repeat service.
● When storing sheets, where possible, lay flat with support of bearers.
Spacings for framing supports depend on the properties that pertain to the sheets construction and direction of the face veneer (table1). These values are used in conjunction with standard engineering standards to design the form to withstand the pressure developed by the wet concrete and how much deflection is allowable.
The actual thicknesses of our sheets are 12.5mm and 17.5mm but the 12mm and 17mm values in the tables can be attributed to our sheets.
IPL Formply is made to the highest qualitylevels based on the requirements of the Australian/ New Zealand standard 2269and AS6669 in conjunction with the Engineered Wood Products Association ofAustralasia.
