Bedding hardware on teak decks

[Streetcar]

I am about to start bedding a set of load bearing pad eyes (for halyard blocks) onto a teak deck. The construction of the deck from top down is:

- teak (bedded not screwed)
- polyester GRP (6mm approx)
- plywood (14mm approx)
- polyester GRP (6mm approx)

THese are heavy duty pad eyes with 4 x 8mm bolts around the plate and 2 x 10mm bolts on the main load bearing eye.

The most critical seal is at the top GRP layer. Without the teak I would normally countersink the holes at this layer to get a good ring of sealant around the bolts. The presence of the teak layer makes this very difficult.

What is the best way of doing this job to ensure that there is good long term seal in a highly stressed deck area?

Make sure you have a substantial SS back plate on the overhead. If you are worried about the teak deck/FRP interface leaking you will have to address that the Mainsail way Re-Bedding Deck Hardware With Bed-It Butyl Tape Photo Gallery by Compass Marine How To at pbase.com
