Subject: Filling Deck Holes
Info: (950 views) Posted: Sunday 3-6-16 01:09:12 PM
Thanks everyone, especially for the info in Vinyl vs Epoxy. I had completely forgotten about that.

I will be resurfacing the deck after doing all this.

So it sounds like the best way to fill abandoned holes is just to over drill from the top, use green 3m painters tape on the bottom, then fill with vinyl resin (probably with a syringe) carefully from the bottom up to avoid air pockets.

For holes that are going to be re-used for hardware, over drill from the bottom up leaving the top fiberglass intact, coat an appropriately sized G10 tube on the top and sides with vinyl resin, then insert it up from the bottom. The intention here would be to vinyl resin glue it to the top layer of fiberglass and stop any water incursion there. Seems to me if I accomplish that well, then filling in any cavities around the sides of the tops where the G10 would be touching balsa is desirable but not critical.

Does that sound like a good summary of everyone's tips?

:: :: The _best_ way to fill holes being abandoned is to

:: :: (extending 1/8-1/4" beyond the hole) fill them with
:: :: thickened vinylester and cap them with little circles of

:: :: It is MUCH easier to work with since it is much more

:: :: :: Let me recommend NOT using epoxy resin. It shrinks over

:: :: :: core (ask me how I know this!). The best solution is to
:: :: :: use vinylester resin and G-10 rod in each of the holes.
:: :: :: The G-10 will keep you from over compressing the holes

:: :: :: :: :: Hi all,

:: :: :: :: :: I've removed all the hardware from my deck and am about

:: :: :: :: ::
:: :: :: :: :: I'm wondering if anybody has some good tips on how to

:: :: :: :: :: the interior.
:: :: :: :: ::
:: :: :: :: :: Taped on wax paper under the hole? Wait until epoxy is a
