Application

A portion of the band is cut from the roll, enough for the application surface. The exposed side of the band is adhered to the concrete and in order to achieve greater adhesion it is pressed against the concrete for a time. The joints are placed 10 cm apart from each other and not on top of each other so they don’t overlap. After the band adhesion process pour the concrete over the band without damaging it.
