lateral 110 Posted October 8, 2019 Report Share Posted October 8, 2019 Last meticulous prep now looks like shite. It was several coats of west with uv hardener (407) and six coats of vanish. Didn’t last more than 18 months And at 3.5 yrs looks like a case of leprosy. Any proven formulates? Should have had a cover. Quote Link to post Share on other sites
Black Panther 655 Posted October 8, 2019 Report Share Posted October 8, 2019 Sand and revarnish with polyurethane, like they use on wooden floors. Then get a cover. Quote Link to post Share on other sites
MartinRF 11 Posted October 8, 2019 Report Share Posted October 8, 2019 I know you live in a sunnier place than I do but still I think it should have lasted longer. What type of wood? Oak and epoxy for instance is non-trivial to make work in my experience. Then we have tho option of KISS. If swelling/shrinking with variations in humidity is not an issue for this tiller I would consider good old one-pot varnish. Yes, it will need to be re-done on a regular basis but it is not hard work. A cover will extend the service interval considerably. /Martin Quote Link to post Share on other sites
Black Panther 655 Posted October 8, 2019 Report Share Posted October 8, 2019 Ordinary varnish two coats wvery 6months. Quote Link to post Share on other sites
Terry B 29 Posted October 8, 2019 Report Share Posted October 8, 2019 I took my tiller back to bare wood 6 years ago, epoxied 1 coat then only 4 of spar varnish. Then got a soft sunbrella cover made. Still looks like new (apart from where I dropped the boom on it ). It's the cover that protects it I reckon. Quote Link to post Share on other sites
Vorpal Blade 87 Posted October 9, 2019 Report Share Posted October 9, 2019 When you have finished varnishing it take it to someone to make a fitted cover for it, then install tiller on the boat - much cheaper than having someone go to the boat and measure/make. ex Elly 1 Quote Link to post Share on other sites
rigger 25 Posted October 9, 2019 Report Share Posted October 9, 2019 Strip back, 80 to 100 grit, 80/20 thinner/varnish ~ couple of coats 50/50 same Then 6 to 8 coats for a total of no less than 10. It may be worth wet sanding after 4 coats for a better finish then another 4 coats. Get a cover for it, if not wet sand 400 grit and 2 coats every 6 months. Schooner or gold spar / similar Quote Link to post Share on other sites
mcp 20 Posted October 9, 2019 Report Share Posted October 9, 2019 It was several coats of west with uv hardener (407) 207? ........407 is a fairing compound. And like above, sand + polyurethane varnish. Quote Link to post Share on other sites
lateral 110 Posted October 9, 2019 Author Report Share Posted October 9, 2019 Sorry, Yep 207. So seal coat of epoxy not worth the extra work it seems. I have ADH30 hardener to make it MORE flexible? Quote Link to post Share on other sites
tuffyluffy 72 Posted October 9, 2019 Report Share Posted October 9, 2019 Timber tillers will look great for at least 5 years with 5 coats of Cetrol . . . . and a cover. As others have said, a cover will save you a pile of maintenance Quote Link to post Share on other sites
