Instructions

Select the required tape length and width suitable for the dimensions of the joint width and joint depth. The joint edges should be parallel and free of dirt and remains of cement. When unwinding Soudaband PRO MF1, allow for an extra 1 cm tape per running meter of joint. When installing, make sure that the printed side with the inside marking is along the inside of the window. Start at the bottom, in case of vertical joints. Fix the pre-compressed tape with the self-adhering side to one joint edge by means of a filling-knife. After applying, the pre-compressed tape will expand and press against the joint edges and fill uneven areas. For more information, consult the technical data sheet.
