eck is stained with brownish wooden color, a color pigment is mixed with thinned epoxy and brushed over its surface. Epoxy is thinned for two purposes: first, to lower its viscosity so that the mixture flows easier and make a more even surface, second is for the epoxy to be absorbed into the deck, since there’s no glassing for deck, better to add some water resistance capability to the exposed plywood. This has always been my method of treating plywood if there’s no glassing.

Next is to glass the bottom, this gonna be a quite heavy kayak (estimated to be approximately around 25 kg) since I’d decided to glass both the internal and external side of the hull, while the deck only receives some glass reinforcement on the internal side. I run duct tapes along the deck (third image) to mask the margin for glassing, two layers of duct tapes to prevent the blackened epoxy to spill over the deck. One very annoying thing with every duct tapes I used is that no matter how I try…

Epoxy still leaks a bit under the duct tapes, and the border line between hull and deck would become blurry. I used a trick to overcome this problem, after sticking the tapes, I brush a very thin layer of transparent PU over them, cured paint would prevent epoxy from leaking through while still enable pilling off the tapes. Fourth image: glassing the bottom, epoxy is mixed with a deep black color pigment, almost jet – black. Later, several layers of transparent PU would make the final finish.
