There is more than one choice when considering which adhesive to use and each choice has certain advantages and disadvantages. PVA, polyurethane and epoxy are three options that are commonly used in the construction of strip planked hulls.
Water resistant, easy to use, cleans up with water, makes a strong joint if properly clamped, relatively inexpensive.
Waterproof, easy to use, cleans up with water, makes a strong joint if properly clamped, relatively inexpensive.
Easy to use, cleans up with paint thinner, makes a strong joint if properly clamped and costs substantially more than PVA glues.
Waterproof, most expensive option, typically must be mixed per batch, makes a strong joint without clamping pressure, difficult to clean up.
Silica thickener for making thickened epoxy adhesive.
There are many ways to learn to safely use the tools and execute the processes necessary to build your hollow board. But the bottom line is this: Tools and the dust they create are dangerous. If you are a novice woodworker, educate yourself about tool safety and proper shop practices. Power tools are very unforgiving and trouble can happen quickly if you are not prepared and diligent in your approach to how you use these tools. Regarding the health consequences of breathing wood dust, take this issue seriously. Use good respirators with fresh, clean filters when cutting or sanding wood. This is also true for applying and sanding epoxy and other finish products. Uncured epoxy is toxic. Most of the ultra violet inhibiting finishes that go over the epoxy for the final finish are also toxic. Use the tools and materials at your own risk. Educate yourself and work smart and safe!
