Filling bolt holes in a teak deck.

[burgundyben]

I have 6 bolts holes in a teak deck to fill, 8mm bolts came out, there is a 10mm ply underdeck and the teak itself is about 6mm thick, so about 16mm bore to fill.

I propose to tape up from underneath and dribble in epoxy to fill the bottom half, once set, I'll shove in a teak bung with black deck caulking goo, once cured, chisel off and sand.

Sound ok?

Presume you are thickening the epoxy? If so should work fine.

Yes, thank you, thickened. I've various tubs of bubbles and fibres to knock up epoxy jollop.

I think I would fill the entire hole with epoxy (unsure why thickened), allow to cure, make an over sized hole (10 or 12mm) with a Forstner bit for the teak plug and glue it in with poly urethan glue.

Thanks.

One of my concerns is that a tiny ring of glue or caulk around the perimeter of the plug will be exposed to UV. How is polyurethane glue with UV?

Watching Tally Ho has made me neurotic about the prospect of even the tiniest thing becoming a massive nightmare!

Polyurethan glue is very good with regard to UV, much better than epoxy. I have used both. The former for the teak deck that I relayed in in 2008, not a single plug has yet come out or showed sign of becoming unstuck. I have also used epoxy, mostly for renewing plugs on the teak cap rail. The glue seam will become brittle after a few years in my experience.
The thing about filling the entire hole is to make it possible/easier to centre the drill bit. Use a high speed drill.
