Re: Replacing plywood on boat floor Peanut butter is resin mixed with wood flour to the consistancy of pb (i.e. it stays on the mixing stick). If the gap is larger than 1/4 inch or the hull slopes away too quickly, you may need to glue 1x1 inch peices of wood under the gap to hold the glue and the new floor.
It's very easy to put a new floor in most aluminum boats, so the down side of a low cost job not holding up long enough and needing to be done again isn't as critical as on a fiber glass boat. Cheap exterior plywood and some kind of deck or porch paint for wood will hold up for several years and just use some sand as a non skid finish.
Marine plywood is a great sheet material that can be easily cut using both hand saws and basic power tools. Marine plywood is often used to build boat interiors and to replace flooring during boat renovations.
Therefore, it will need replacing. Here are some steps to follow and a list of the tools and materials required in order to do this successfully. Step 1 - Remove the Damaged Flooring. The most common material used for boat flooring is BC plywood, and it is also used for fiberglass boats in particular.
Peeled off all the old carpeting on my boat, and realized most of the wood in the back half of my boat is pretty rotted. My question is, is there a specific type of wood that I am supposed to use to make the floor of the boat. It looks like it was really thick plywood, but that wouldnt seem right...
The need for a new boat floor becomes inevitable when the floor has a soft, spongy feel that is a sure sign of dry rot. However, the need for replacing a boat floor does not mean the end of your boating days. You can replace your floor in a short amount of time and with minimal labor.

A boat floor is not meant to have nails in it and doing so weakens the structure. It also creates spaces where water can get deeper into the boat, the floor, and other areas. Even a gap as small as a nail head can wreak havoc on an otherwise healthy boat so when replacing flooring, avoid nailing altogether.
