Resin Question from an overly ambitious newby

[Krfoote]

I am about ready to reinstall my deck and cabin floor (i dunno the nautical term for floor) and i am reading all about a seal coat of resin on the dry wood before laying up the fiberglass.

I understand all of that, Except the "Resin" used for the seal coat, Is that the epoxy or poly resin that is used for the Fiberglass... without the CSM or WR? Or is it something completely different?

Seems like a silly question but I am ready to start and i really want to make sure i am not guessing before i get started!

What type of wood are you using. is it dry marine grade plywood or balsa? I generally dry fit and cut everything first, then mix small batches of resin and begin assembly slowly. Let the resin begin to set and then wet in the glass fiber after mixing my next batch. This allows be to keep buildin without having to wash amine blush or grind cured resin between layers.

I am planning to use Dry Plywood (I believe its marine grade).
So i can install it a piece at a time without seal coating it first, i just let a layer of resin soak in for a while first?

Re: Resin Question from an overly ambitious newby

That is correct The most important thing is to allow the resin to make all components fuse into one strong structure. Not to glue layers together using resin. try to get out all the air between glass layers. A:redface:ir pockets deminish strength and allow water a place to cause rot.

The resin used to pre-coat the wood is the same resin you will be using for the entire job, not something different.

The reason for pre-coating it is to allow the wood to soak up as much resin as possible before doing any glass work. This does two things.

1. it lets the wood soak up as much resin as it needs so the bond will be good.

2. if you just glass over un-coated wood it will frequently suck resin out of the glass leaving dry spots that will be weak and need to be repair after it cures.

If the wood is very dry and porous it may need more than one coat.

Not bumping heads here,But--if you don't let the first coat (or 2) of resin dry,you will still have a chance of a dry spot.Also using UNWAXED resin is key.It'll dry tacky,that's good!! NO sanding,Then when you think it's sealed,do your glassing as normal.I have stated before that reading instuctions in posts sometimes are misunderstood and with the amount of work and money your facing--one doesn't need to mess up on the start.So,Read,Read,then read some more.Once you got the game plan,then go to work.

I'd install all at once so you can put a thin layer of glass on teh underside too... whatever you do, make sure the entire thing is sealed from water intrusion.

I think you have the point here though... just paint a layer of resin (epoxy or poly, whichever you're using for the glass), over every inch of the wood first.

And deck is the nautical term for the floor.
