attaching wood furring strips to inside of hull

Hi all,

Looking to do a modified version of the project at The Frugal Mariner: Insulating your boat. I'm going to put some hardwood strips on the hull and then attach some frp to replace the 33 year old carpet.

Question is what should I use to attach the wood to the hull? It won't need a lot of strength, but it needs to stick and hold up to 10 pounds of weight.

Epoxy? Liquid nails? Something else? The more specific the better.

Thanks,
Ken

I used gorilla glue to attach the furring strips to the hull. After 24 hours I can't move the strips.

I think gorilla glue (polyurethane if i recall) is a great idea. Cures in the presence of water, waterproof, lasts a long time.

Yea, the down side is one has to wedge the strips in tight or the glue expanding will misplace the strip.

Re: attaching wood furring strips to inside of hull

Generally there's some curvature so some way of wedging things in for the cure is usually called for anyway. I used 3M 4200, laid some closed cell foam in the areas between the strips and covered it all with battens. It looks great, flat panels will often be difficult to fit to even a minor compound curve.

It wasn't a large area, but the side of the berth shown below was just a cushion laid against the bare glass originally.

Barquito and CalebD like this.

Faster,

I like the way the wood warms up the berth. Is that Cedar, Spruce, or what species?
Very nice.

I think you can use a urathane or epoxy adhesive for hanging stuff to the hull if your boat is relatively dry.
I have seen people use Liquid Nails and I cringed, but the adhesive held up nicely on a Sunfish. I prefer to use "genuine boat snot" for repairs on my boat though; Liquid Nails is a household snot. 4200 should qualify as a genuine boat snot even though it is only a one part adhesive!

Captainmeme, that's what packing tape is for. A layer of masking tape on the furring/ferring strip to make removal easier, then packing tape attaches the wood to the hull while the GG dries.

Re: attaching wood furring strips to inside of hull

Why not just use thickened epoxy, like in the Frugal Mariner? Epoxy is good for everything on a boat

Yup! Or a vinylester paste. It will be a little less brittle than epoxy over the long haul with superior adhesion.

Thickened epoxy.
Dabs of hot glue from your hot glue gun to hold in place while the epoxy cures.
