Re: Fastening plywood in a bus
If moisture is a concern you can use a product like "DryPly" .. it's a tongue and groove sub-flooring designed for humid environments and occasional exposure to moisture .. it is not designed for prolonged or continuous use in "wet" environments (such as outdoors or for a deck) .. great for bathrooms, kitchens, and laundry rooms where you expect to get wet once in a while ..
.. it is also T&G, which makes for much stronger joints that won't "rack" or move horizontally when you step on them ..
.. it is available at most Home Improvement stores .. not much more expensive than regular T&G sub-flooring .. I would stay away from the OSB sub-flooring though, especially if moisture is a concern .. regular old T&G sub-flooring should hold up just fine, especially if you use a low-voc sealer ..
.. hope that helps ..
