Abstract:
1. A shuttering element including a panel-shaped carrier having opposed sides providing support surfaces for cooperating in the shaping of uncured concrete and a rigidity sufficient to enable said shuttering element to be used as a form to shape uncured concrete, said carrier being reusable and susceptible to damage at said support surfaces during use, a film covering at least one of said support surfaces on at least one side of said carrier, said film having a first outer film surface forming a contact surface with uncured concrete to be shaped, said film having a second outer film surface remote of said first outer film surface attached to the carrier in a replaceable manner by a film layer adhesive capable of deactivation by heating, said film being removable from said carrier without damage to the carrier upon deactivation of said film layer adhesive and replaceable with additional film free of damage resulting during contact with uncured concrete to be shaped, said film contacting and shaping concrete as the concrete is cured so that the concrete is contacted with said contact surface and any damage to the shuttering element support surface will not be visible or transferred to the concrete, and said carrier is maintained as a part of said shuttering element upon reuse.
