The three-layer bonding guarantees high measurement accuracy. Each of the three layers, both the longitudinal outer layers and the diagonal inner layer, is waterproof. They are covered with a special coating of melamine resin, which prevents concrete from sticking and makes them easy to clean, and with paint, which provides protection against harsh weather conditions. Thanks to the sanded surface, the concrete structure is perfectly smooth after formwork. Pfeifer formwork panels are available in both wrought with front edge protection and unwrought versions.
