SWISS KRONO OSB Formwork can be joined using screws, nails or staples and is easy to saw, cut and work. When suitably pre-treated and cleaned, the OSB-based formwork panels are very easy to strip and can be reused multiple times. After several uses, the strand structure of the OSB board behind the phenolic-resin-saturated paper film is transferred to the surface of the concrete.

Before initial use of the panels, two coats of a suitable release oil should be applied to them. The second coat can be applied as soon as the first has dried. (Make sure to follow the oil manufacturer’s instructions.)
