Laying Down the Patch.

Laying Down the Patch

Step 8 continued: Typically, a round area at the top of dome being retrofitted would be washed and prepped for a new piece of Airform fabric to be carefully heat-welded to the existing Airform. In this case, we put down a layer of NP1 and placed the fabric on top of it. Next, we will roll it from the center outwards so it’s nice and flat. Then, we’ll weld the edges to the dome.
