Default Repairing a Rotted Core

Greetings,

I've read through the archives, but I'm still not sure how to address my particular situation.

The rear decking/seating of the boat has a plywood core, and the prior owner had seats screwed into it. He removed the seats and did not seal the holes, so there is some rotted wood in the core. Using the good ole tap test, there's some delamination and also some voids where the wood must be gone entirely.

I don't want to cut the skin off and re-core, and plan to go the route of using Git-Rot or CPES. The question I have is, these products absorb into the wood, but I'm assuming they're not designed to fill in the areas with voids (no wood). Is this going to be a multi-part process? Git-Rot followed by something else to fill the voids where wood is missing and also fill in the areas with delamination?

Thanks for any input!

these pictures - take a good look,they will represent what's going on in the deck.
i can promise you,there's no such thing as an easy way to repair this,no pour in product,no squeeze in product,absolutley nothing - attempting it,you're wasting time and money...

I would just cut it out and repair it properly. Putting a band aid on it now might seem like a good idea but it will just cost you more time and money when you have to address the same problem again

What Jawz and MakoMarineSupply said...
There is no product your can pour into the core to repair it. You need to cut the old plywood out and replace it.

Thanks everyone...Just to be clear, this is a seat on a skiff mounted gunnel to gunnel...Thinking about it, it might just be cheaper buying a new seat, now that I see how much the Git-Rot and CPES products cost...

Its really not as bad a job as you think. I recored a fiberglass lyman deck. Cut off the skin, dig out rotten core, layer of west sytem epoxy saturated in fb matt, lay new core in, another layer if matt saturated in resin, put skin back down, a few bags of sand, fertilizer,old batteries, whatever you have for weight, fill the groove where the sawblade was, paint. If you can get at it that is 3/4 the battle.

I used my West Marine hair dryer to warm the epoxy first, that makes it seek out rotted cores.
