In these days I had more time, so I started to build the raft. The 210d fabrics from extremetextil is really pain in the ass. It is very difficult to seal with the Clover Mini, sometimes it is just not possible. At some point I gave it up, and I just sealed the tube pieces to the floor with my household iron. I used painter’s tape to cover the left and right sides (see photo). It still needed extreme amount of heat (between 2 and 3 points on the iron) plus pressure. But be careful…
I found helpful to place a piece of aluminum foil under the fabrics. It reflects back the heat and helps to have a better seal.
Today I started to join the completed tubes to the floor, pf… again problems with the 210d.
