We scraped off the last piece of teak today on the coachroof (saving the bow and side decks for next winter). Now I am using the oscillating tool w/ scraper blade to remove all of the left behind excess glue. This just leaves behind the stuff in the nonskid grooves, and with some sanding, I think the surface will be sufficient for laying down the synthetic.
The immediate priority is to seal up the 100's of screw holes which go into the core. Even though the boat is shrink wrapped, rain travels down the mast and then forms a river across the newly scraped surface and many exposed screw holes. I'm going to ream them out tomorrow, dry them out using a heat gun, and then squirt in some penetrating epoxy.
Obviously our boat lists to port because the water from the mast always flows to the port side. This also explains why my son's room has moisture problems and my daughter's doesn't.
I tried to make a catchment system to collect and drain off the rain water (see photo) but it was a failure. Water seems to go everywhere but the catchment. However, once I seal off the screw holes, I no longer care about the water.
If your deck is not covered, don't attempt removing teak if you expect rain any time soon.
I also ordered a paper template of the deck pattern from PlasDeck, which I will dry-fit to the deck for one last time before I put my deposit money down and get on the production schedule. This is not a mandatory step but for $200, it's a good insurance policy to make sure everything lines up. It gives me the chance to make final alterations in the event some of my lines or measurements were off.
