Re: deck leak

I am glad that you pointed out the concern of leakage into the core from cracks as this does happen. Not all cracks are the same, some are a concern and some aren’t and telling the difference is sometimes difficult. Here are a couple general things that I have learned.
1. Cracks that occur near a high load areas where hardware is attached usually extend into the glass laminate.
2. Cracks that form on an open deck area such as what we commonly see in the simulated teak decks should only be in the gelcoat so there is no path for water to leak into the core.
3. You can get some idea of whether a particular crack is serious by how much displacement there is on the surface. Is the top of the crack level or is one edge raised? If level, odds are pretty good that the laminate is still ok. If you can catch your fingernail on a raised edge, the crack likely extends into the laminate at least some.
3. Your advice to fix damage caused by dropping something heavy and fracturing the glass laminate is really good advice. An amazing amount of water can enter through even a small crack or hole over time and it is a one way trip since it is pretty much impossible to remove short of using vacuum pump.
