No, I have not cut up strip planking to check the saturation – I have just noted that the kayaks epoxy-glued in one go is as light as or even lighter than those glued with PVA or PU (which I dislike since the foam formed at curing is a mess to sand and often stain the wood). Otherwise there is no apparent difference in strength or longevity, but I have had some problems with the PVA-seams becoming visible (protruding) in certain weather conditions.

Of course there are pros and cons with my method. It is a quick way to build a hull – no waiting for glue to set before attaching a now strip – where you use glue at one occasion instead of 70-75. It allows for adjusting the strip lineup up to the glueing. The obvious downside is that you are wasting epoxy all over the surface – epoxy that has to be sanded off before fairing the hull.

There is no need to leave a gap between the strips. Epoxy is a relatively low-polymerized resin (smaller molecules than most other resins), penetrating gaps between the wood cells (typical 1/1000th of a millimeter) – meaning that however careful you are with joints you can never keep the epoxy out! The problem is the opposite – to fill the larger gaps formed on the outside by the curvature of the hull (the wetting properties of epoxy may compromise this, and necessitate the use of thickened epoxy).

I have at a one occasions had a couple joints opening during the sanding process, which I believe happened because I wasn’t careful enough when spreading the epoxy over the surface. They were easily reglued, with no other disadvantages but an irritating delay in the fairing.
