Bed decks and covering boards?

Post by JacobErdey » Mon Dec 24, 2018 5:02 pm

Haven't thought of it much up to this point, but I am about to start fitting the fore and aft decks and all covering boards (on my 1950 18' Utility) and was wondering if those just go on dry, or do those need to be bedded in 5200 just like everything else has been? Seems like something that could be done either way, just seeing what the best plan is there. Thanks

I would use a little Dolfinite, not so much that it comes out the live deck seams. It's got enough stickiness to dampen movement and it helps seal against moisture intrusion.
Boats are to be made of wood, otherwise, God would have grown fiberglass trees.

5200 is a super powerful adhesive and an excellent marine sealer. My only gripe with it is, in the classic wooden boat restoration world, whatever you put together with it will never come apart again without using destructive force. In other words, wooden boats assembled with 5200 are no longer restorable. But, if it’s a matter of a classic ending up in the burn pile, or a 5200 bottom, I’d rather the 5200 bottom. We’re lucky Chris Craft didn’t use it or we’d have no old boats to restore. The way they were built originally held them together fine and they lasted a long long time.

Yes I agree that it is fortunate we are able to restore these boats given they weren't all glued together originally. I did do a 5200 bottom on mine and bedded the sides (all new wood on almost every piece because I was completely green when starting this project and didn't realize that I was about to be completely redoing a grey boat) but I think I'm going to put the decks down dry for now, and hope for the best. It seems that is the way they were done originally anyway. Thanks for the input

More then likely the only reason to remove a board bedded in 5200 is because its been damaged and requires replacement. Thats when a router becomes your best friend.

So I had this same debate with my restoration and the guilt of bedding all planks in 5200 knowing that the next restorer would not be able to remove the planks in one piece to use as patterns like I was able to do.

In the end I bedded all planks in 5200 - including the deck planks. All new wood. To this day I have no regrets. I have no open seams and no cracked seams on the deck grooves.

To help with the guilt part I made patterns of all of the original planks by tracing them on the thick paper that is used under hardwood flooring. These patterns will go wherever the boat goes be it family or a future purchaser.

We bed all deck planking with 5200. To me its a bad idea to build a boat with the thought of taking it apart. We have had to do repairs on decks that were 5200 in and were able to remove them with a multi tool or if needing to replace one we router out the plank. Then make a good pattern for the new plank before we cut it out of new wood.

Is there a reason folks don't mention using Sikaflex when bedding deck planks?

Sikaflex does not have the same adhesion properties as 5200. Use that for deck seams but not for bedding planks.

I have come to believe that the true mark of a product's durability has a direct relationship to how difficult it is to remove from hands, clothes, tools and your hair. I can say with certainty that 5200 cannot be removed from your hair without scissors and my cordless drill will never look the same. Not that Xylol/Xylene can't remove it if uncured but some things don't respond well to it.
