I need to tidy up the thwart on my Europe, a good rub down and varnish. What the best stuff that actually goes off properly hard in days rather than weeks?

I have only used yacht varnish, think the last tin was B&Q own brand, never used any varnish in cold and damp, so, can't advise.
I can recall someone painting a boat in a tent in the winter, that wasn't too bad a finish.

At this time of year, nothing without heat.

If you can get it warm enough, with bare wood, then isocyanate clear varnish like Bondaseal will give you 3 coats in about 3 hours and then take another 24 hours to cure completely. More "normal" varnish, go for a 2 pack polyurethane, I guess. Never liked the stuff, myself.

The thwart is off the boat and in the house, so I guess that will help.

Yes it will! But don't use isocynate varnish in that case, as the smell lingers for days and gets you high, followed by headaches.

If its off the boat and in the house you can probably use pretty much anything *but* you need to consider the rest of the household and fumes. Some people find the solvents difficult to tolerate, especially the more aggressive chemicals in the high end varnishes. Oh, and don't use two pot in the house at all. Too toxic.

We have all become environmentalists and risk averse, I won't let the kids in the kitchen if there's cooking going on or use the mower or shears. I had to do loads of dangerous things when I was a kid, I was in charge of lighting the fire and loads of chores that I think are dangerous now, where are we all going?

Way off topic, but really? How are kids supposed to learn a) how to cook and b) how to mitigate risks if they are never exposed to an active kitchen?

Not sure toxic fumes fall in the same category as the above. Long term health damage makes me cautious.

The rescue boat for our school sailing club was a rowing boat, which would require somebody to sail in and row back out again should it be required

I just used blakes dura-gloss to varnish my carbon mast. Its in an unheated garage and was hard well within the stated 8 hours!

Think I just used international original. However, my boat is in a minority as most Europes have teak thwarts which don't need varnishing. Which boat do you have?

Epifanes or Hempel Favourite both go hard. At this time of year you will find they will be set in around 16 hours but will take a week or so to fully harden off. In the summer it is more like a couple of days to be fully cured.

It wasn't, it was dry. Its not the same thing :)

If you handle it or got it wet you would have marked it or sent it milky - whether this bothers you is another matter.

Even two pack varnishes aren't properly hard until 36-48 hours after application in summer.

I have an old Rondar, the thwart is some sort of hardwood. It was covered in something that was well past it's best. I ended up using some generic yacht/exterior varnish - it's had plenty of time to go off between coats and actually looks ok. It will be interesting to see how well it lasts. Now the aged RWO traveller looks a bit xxxx Big smile

Another vote for Epifanes, keep working the wet edge and donít got back over where you have varnished particularly with Epifines. I always use a simple polyurethane tent over the area and an oil filled radiator- economical and no blowing. You need to pre heat the boat for 24 hours. Do not varnish and the turn on the heat you will get lots of bubbles. The secret to varnishing is a very clean brush - what people think is dust contamination is dried varnish coming out from deep inside the brush. 

PS - sold my wooden boat but having moved bought a Laser as we have 365 days a year sailing (Normal year)
