My circa '69 14' Pintail had water saturated end-grain balsa deck core. This was exactly what I needed to replace this and rejuvenate this classic sailboat.

Sandwich between two layers do fiberglass, this wood becomes very ridge.

I had a small soft spot in the deck around an inspection plate. I had access to remove the bad core and replace it with the new balsa. After epoxying the balsa in place I remounted the inspection plate.

Used it for deck repairs. If you have spongy decks or roof my advise is to do sounding testing with mallet and precisely mark out area that has wet or roten core with marker. Then cut top skin using skil saw and pry out remaining balsa. save top skin. clean/prepare bottom skin. use top skin as template to trase shape on balsa. lay balsa with thikened epoxy prewetting with unthikened epoxy. use west system notched spreader. lay top skin. add weights or drill holes and use butterfly ancors to tie down sandwich. next day grind a recess in top skin. lay 1708 tape . next day sand and do some fairing job. good luck

To answer Gary's questions. I used 3/8 thick but 1/2 inch would have been better. It is not primed but that wasn't a problem. I used West systems epoxy and had no problems. Make sure the old core is cleaned out really well so that the epoxy and new core will bond realy well, saturate really well and cover with cloth and it should work great.

We had to replace the roof of the aft cabin and the floor to the fly bridge of a Marine Trader 34 because the teak decks had leaked. We cut out the core (plywood squares) and replaced it with balsa, fiberglass and west system. The area is now VERY strong and water tight.
