I used the laminating resin as a base layer, laid the fiberglass then a sealing layer and put in the floor.
What? This can't be right, it reads as open hull, resin, glass, resin, lay wood in, then pour resin over everything.
Unless you mean you glassed the floor outside of the boat, then laid it in the hull and sealed with resin.
Either way is wrong. It should be as follows.
1. Dry fit all floor sections at the same time. Set two screws in each piece for alignment later, they can shift after you take them out.
2. Seal the bottom and edges of each piece. A single layer of glass should do. Of course, this is impractical for the edges, so just resin them as thoroughly as you can.
3. Screw floor in place. Some people set the pieces in thickened resin. Up to you, but you're racing the clock there.
4. Glass floor in. Each seam should have glass on 6 inches of either side. We usually use byply for it. This also depends on your choice of covering. A thick carpet will hide the high spots pretty well, but if you use thinner material then you will need an even surface over the whole floor. So you might need to glass the entire surface.
