HOT COATING / SAND COATING
For some boards, this is the final step in the creation of a perfect ride. The hot coat puts a smooth, thn, hard layer over the fiberglass-dimpled laminating coat. By comparison, wax-free laminating resin is slightly gummy, even when dry. Hot Coating is applied after the lamination. The process involves application of a second coat of resin that is brushed on the fiberglass. This resin contains a wax-based sanding agent, which rises to the top as the resin dries. This process creates an easy-to-sand surface.

After the board is hot coated, the fin system is added: boxes or plugs for removable fins are sunk into the bottom surface and set in place with fiberglass cloth and resin.
The board is then machine and hand sanded for the perfect non-glossy finish.
