I've tried to paint
the topside of my boat
(roller and tipping) strictly respecting the paint
manufacturer recommandations, i.e. 10% of thinner (two parts
It's been a disaster...the paint was feeling like jelly, barely flowing and very hard to tip...
Later, talking to a local painter, he told me that given the temperatures outside (above 78°F in the shade) he doesn't hesitate to use 20 to 30% thinner...!
So I plan to sand everything and do the job over again...but later when the temperatures are a bit down.
This makes me wonder if one can find somewhere a chart showing the relationship between temperatures and percentage of thinner?
