wymberley Posted May 14 Report Share Posted May 14 Some advice, please, Guys. I have just bought a garden bench seat which is flat pack and has already been pressure treated. Before it arrives in a couple of days could anyone kindly advise me on a quality brush on treatment which I would use annually - starting now before assembly - which hopefully will provide another layer of protection.

Thank you. 25% varnish.............75% thinners.................or recommended thinner..ask your chandler when you varish wood for marine purpose.....you cut it back 75%...then 50%.......25%......then full fat varnish with a sable brush...sanding down between each coat if you cut it back 75% and put it on really dry wood ...it will dissapear...just suck it right in....slop it on a few times (plus the ends) and the wood will be well protected use exterior marine varnish as it will have UV additives in it... you wont need the full fat varnish its a outside bench after all...just stick to cutback and let it soak it and dry between eack coat Quote Link to comment Share on other sites More sharing options...

Thank you very much indeed. this is what you would do when varishing a clinker built sailing boat/rowing boat/waler........and where you have "gaps" in the overlaping planks......you would pour some varish on a flat baking tray...let it alone for a while until it grows a thick skin.....lift the skin off with a wide blade and use it to calk the gaps in the planking....

This we did when I had a 28 foot larch on oak clinker built ex lifeboat many years ago except for the caulking bit. When launched we were told, as it had been out of the water for a long time, it would leak like a sieve, but being larch would take up fairly quickly. On launching we had an electric pump on standby which was needed for about two hours and thereafter the boat was completely watertight. Had I known of Ditchie’s caulking method all those years ago, it would have obviated the need of a pump. As they say, every day’s a school day.👍 OB Quote Link to comment Share on other sites More sharing options...

I do agree. reinvention of the wheel comes to mind. Unlike perhaps the Chinese and maybe some ancient tribes, knowledge handed down through the generations doesn`t appear to always register in today`s society and the same mistakes keep being made. Anyway, hope that you are keeping well, Simon and keep up with your excellent food photos and recipes. Always good posts. OB Quote Link to comment Share on other sites More sharing options...

I doubt it very much. Wooden boats work by swelling and sealing the gaps in the planking. Various methods; caulking (aka bits of old rope shoved into the larger gaps), lead mixed in, varnish, you name it...have to work with, not instead of, wood doing what it does naturally. Even 'modern' plywood boats, epoxied to within an inch of their life 'take up' to some extent. The 'traditional method' was leaving the most junior member of the crew on board with a bellows pump to keep empyting the bilge as it took up.

Old Boggy Posted May 16 Report Share Posted May 16 I must admit the advice we received to let the larch clinkers take up themselves naturally was from an old established boatbuilder, so he obviously knew his stuff and was spot on with his predicted time that the larch would take to swell up and provide a watertight boat.
