I am an ex-pat in The Netherlands. I am presently wooding the hull of my 1969 Nordic folkboat. Kitt or Max or something was used on the seams. Something like 5200 I believe. It was applied over 40 years of paint and not done well. Anyway, I am scraping off as much as I can with a carbide scraper, combined with a heat gun and hacksaw blade. I think all of the oldtimers have given up as I can't find them any more. They all have steel or plywood boats. As I don't speak Dutch, I am finding it a real problem. The laws have changed as to what is allowed. I have found tar, 5200, Epiphanes, International, etc. So bending the rules is still possible. Okay, to the question. I am doing the hull. Varnish above water and white paint below. I am unsure as to how tight the seams are. They were coated with a bead of "kitt" or something. Scraped that off down to mottled wood. What do I do now. The "expert" here says to pay it with 5200 then Epiphanes underwater primer then Werdol Koperfril I would love to order from the states, but it is hazardous cargo. I can find lead, lindsead oil, etc. I plan on refastening the planks next year, which means that everything that I do this year is negated. I know that there are several horrible repairs in the planks which I will need to do in the future. I also know that the planks were patched with epoxy which needs to go. I also know that they need to be hardened or refasted, I am a beginner, but I know what I am up against. I bought the boat and went two days down the canals and up the rivers without pumping. Some water came in, but not much. It was raining hard and we were all soaked. I thought that it was a great beginning. Not sinking the first day is a plus. I am worried about the seams in the lapstrake. The "expert" says to pay those seams also with mahogany colored 5200 then to varnish. I don't think the varnish will hold up to the flex. What about to hull underwater? What do I do? 5200 and then paint or clean and hope it comes together? It hasn't been out of the water long. I need to know what to do. Leave it alone sees a better idea, but I don't want to sink either. I won't pay the seams with cotton and lindsead oil. I don't want her to break apart. This is what the expert says without looking at the boat because he has one I guess. Tar for the cast Iron. Hard to get, but still able to find. 5200 for all seams almost imposible to get, but I found it here, Epiphanes, underwater primer, Werdol Koperfrij topcoat. PLEASE HELP ME. I need to know what to use over here.

He Serendip,

Where are you located ?

Maybe I can give you some pointers for obtaining specific materials. You are right coal tar is banned here. There are a number of alternatives both from Epifanes and a firm named Tenco.
You are still allowed to use certain copper based antifoulings, when the manufacturer has filed for an 'admittance number'.

Thanks Duncan,
The boat is on the hard in waalwijk. I have wooded the hull. I want to refasten, but that is going to have to be next year. One thing at a time. I am afraid that all of the traditional boatbuilders have moved on. I really need some sound advice on this boat. For example: The cabin was painted. The wood swelled and the paint cracked. Originally, they used canvas bedded in paint. My cabin doesn't have handrails or edging. How do you stop the edge of the canvas and transition it to the varnish for the cabin sides? l think at this point I should just put primer and bottom paint on the bottom instead of 5200 (which is expensive here and almost 2 hours away for the closest tube) I am concerned because when I did remove the old sealant, water came out in a small stream in one area. I am cleaning off the goo down to polyurethane impregnated wood. Paint goes on next week. and then it needs to be in the water to go to Belgium.

If uor going to refasten anyway. I'd not worry about being too traditional this year. Pay the seams as they say. Then be prepared for some major work next year.

Enjoy your boat for a while. There are plenty of wood folkboats in Europe. I'm sure the help is available. Have you been in touch with Martin on this forum
