The tarpaulin should extend about 10 centimeters on each side of the frame, to ensure effective stapling and tension. Begin by stapling the tarpaulin on the separation strip as shown in the diagram (diagram to be added). The tarpaulin should then surround the lower part of the frame and go up, without any staple less than 7 or 8 centimeters from the bottom, at the risk of having water leaks. It will bend the overflowing plastic and staple so as to ensure a tight tank at the bottom of the frame. Finally, cover the panel of the whole tarpaulin and stretch it as much as possible by stapling it inside the frame. Repeat these operations for the second frame.
