In this step, we’re going to attach the tubing pieces to the floor of our packraft.
Start by laying out the floor piece with the shiny TPU-side up. If you have chosen to add a second floor piece to your packraft kit, you can set that aside until a later step.
Now align one of the tubing pieces, TPU-side down, in between the two dots on the floor that correspond to its position. Double check that it is in the right place by referring to the stickers on the fabric pieces, and the following image (if the stickers have come off, check the bottom of this page to learn how to tell which is the front-facing edge of piece 3 Left and 3 Right).
Do not confuse the Left and Right side pieces or your packraft will not fit together properly.
With the tube piece aligned between the two dots, begin sealing it to the floor near the center of the joint with your heat-sealing iron. Work your way toward the ends, leaving 1.5-2 centimetres unsealed at each end (these ends will be sealed later).
Once the majority of the joint has been sealed, carefully work your iron along the edge of the seam, ensuring that you form a good bond right up to the edge of the floor fabric. If you’re worried about touching the TPU surface of the floor piece with your iron, you can cover the TPU with a piece of parchment paper. When the fabric is bonded to the edge, flip the pieces over and make sure the bond is complete to the edge of the tube piece.
After that tube pieces is sealed to the floor, you can bond the rest of the tube pieces to the floor, following the same procedure until all ten are done.
In the next step, we’ll join the tube pieces to each other, and the packraft will start to take shape.
