Ok I now need to put the new floor down on my bayliner, should I use regular plywood or do I need to use Marine grade ply...?<br />also I need to know what is the step by step procedure on how to glass the plywood? If anyone has good website that has steps on glassing please provide link.<br /><br />Thanks for your input!

Re: Glassing

There are 2 schools of though here. <br /><br />1. Go marine grade as there are not voids or spaces between plys to get water in and then rot from the inside.<br /><br />2. Use exterior grade plywood. The glue used to put them together is the same as marine plywood but there are voids inside the plys.<br /><br />Personally I am not building a tank and have very little money so I an going to use exterior grade 15/32" plywood.<br /><br />On either type it is best to coat the top, bottom and edges with epoxy. polyester is not going to work as well in my opinion.<br /><br />I am going to use 2 coats on the edges and bottom.<br />1 on top. The reason is I will be coating the top with a fiberglass cloth and 2 more coats of epoxy.<br /><br />I will cut and coat the floor letting it dry between coats 24 hours but not longer than that. To install floor I will lay a bead of epoxy and 1/4" glass fibers mix along the edges where the boat and plywood meet and the tops of the two stringers. I will then run my stainless steel screws into stringer at 6" apart. To finish I will lay 6 inch fiberglass tape arount the edges of the floor and then lay the cloth a foot up the sides.<br />Hope this helps. 1988 Bayliner 1700 Carpi.

Use the red "search" icon at the top of this page and you will find a day or two's worth of reading on "floor replacement" or "floor rot" that will give you a clear picture on the process, including materials and glassing.
