Default Re: floor repairs

I had a couple soft spots in the deck of my Tsunami under the pedestall seats.I had to recore them,and it's a fairly easy fix.

I cut the top layer of glass off,using a circular saw,set to about a 1/4"depth.
I then removed the piece of deck,which in my case was about 24 x 36 inches on each area.That now exposed the core,which was plywood directly where the seats mounted,and balsa core on the rest.

Again with the saw set to a shallow depth,i cut thru the core,(it was 3/8"),just to but not thru the bottom piece of glass.
I chiseled,scraped,and ground out the wet rotted core until i hit dry material.

After i prepped the bottom layer of glass,i laid up a piece of 1-1/2oz mat to it,and let it kick a bit,then took some 3/8" marine plywood,and bedded that into the mat,by applying a slightly thinned hull and deck putty to the faces of the mat and plywood.

I placed a whole bunch of 12lb downrigger weights on the plywood until the resin/putty cured.
When it was done i laid up a layer of mat on top of the repair.

At this point,i think i'm going to put a layer of mat over the whole deck,and mask off sections leaving a white border with areas of gray or tan non skid.

The bottom layer of glass was extremely thin and several holes where the seat bolts were drilled,went thru the glass into the stringer boxes.Also i found vacant holes drilled into the boxes,(maybe for the foam filler)and i think thats where some of the water saturated foam in my stringers came from.

Maybe these pictures will help.
The first one is after i had already cleaned up the area and put down a layer of mat,and the last is one layer of mat over the repair

I thought about matching the original deck floor,but decided against it.
I guess it could be done but it's way way more tedious work then i'm interested in doing.
My use for this boat is strictly fishing,i want it to look nice when it's done,but i'm not interested in having it be the equivilent of a concours classic car.
As i said in my post,i'm going to lay up mat on the whole deck,and mask off areas and do them in a gray or tan non skid,with a white border edge.

If you want to match the original pattern, go to an auto body supply place with the width, I forget what it is, but it's a little off standard. Get the blue plastic tape, spray the whole floor first, then lay you're masking and roll/spray your non-skid. I think that's a detail that looks great, especially if you go a little darker with the non-skid, like a tan.

sorry about the slow replie been busy. goor to looking and i thought the raised section of the floor was engrained in the floor. i didnt know it was just non skip with sections missing where there was tape at. now i know i can match it i am quite please. has any one ever filled the floor area completely with glass resin,instead of putting wood down i am just curious??

Default Re: floor repairs

I thought about laying up several layers of glass,just in the area as shown in the pics.,making it solid,I had lots of leftover glass but after some thought,i decided against it. Too much weight,a waste of resin and glass,and IMHO unnecessary.

If your talking about pouring a resin mix of some sort in there,i tink that would be a mistake.
You wouldn't get very good results.You'd have to thicken it with something like cabosil,but unless you added other stuff like milled fiber,or chopped strand you wouldn't have much strength.

You would add lots and lots of weight to the boat,The cost would be excessive even with Polyester resin. You'd have to rob a bank to use epoxy,and either way what would you gain?

In areas where you'll be mounting things,use plywood,and the rest,use a core material like foam or balsa,or do the whole thing in plywood.
Done properly,it will last as long as you need.

I ended up using a layer of 1-1/2oz mat then the plywood,then two layer of 1708,and two layers of mat,all which brought it perfectly flush with the original floor.
