josephbert Posted June 1, 2011 Report Share Posted June 1, 2011 Question for the wood Jedis. Can a spar varnish be thinned & wiped on like regular old poly? Thoughts appreciated. Quote Link to comment Share on other sites More sharing options...
thewoodwhisperer Posted June 1, 2011 Report Share Posted June 1, 2011 Sure can. As long as you are working with oil-based material and thinning with a compatible thinner.

PerezM Posted May 24, 2013 Report Share Posted May 24, 2013 If you live in California, anything anyone says here might not be correct. None of the solvents and thinners sold in California are worth the cans they come in. So before you start finishing, make sure it is from another state. You will be terribly disappointed if you find out later, you bought the new formulations sold for California. Mineral spirits sold in California and not even close to mineral spirits used in Arizona. Take all the advice and consider the source of the information. California has ruined the finishing industry, as the whole of the US is slowly jumping on board, so buy it all while you can. 1 Quote Link to comment Share on other sites More sharing options...
Boatworks Today Posted May 24, 2013 Report Share Posted May 24, 2013 Only thing I would add (particularly if it's finishing for exterior use) is that while thinning can make application easier it also leaves you with very thin films per coat. What this means is that you'll need to apply more coats to get adequate UV protection, otherwise it will likely fail within a season or so. If it's for interior; wipe away :-) I personally still prefer brush application for varnish, but I am a little weird Quote Link to comment Share on other sites More sharing options...
