Dome
Applying the polyester

Applying the polyester. The mold is one meter deep. To reach everything, a scaffold is placed inside the mold, completely free from the concrete wall. Applying polyester is the most unpleasant part: headache inducing fumes, a lot of mess, and it has to be done right the first time. I am doing this for the first time. I apply one layer per day. After drying, I grind off the protruding fibers with an angle grinder. Only then can the next layer be added. In the end, the dome becomes 6 mm thick.
