paint thinner and outside temperature

[wilparis]

hello,


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 paint).


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?

I tried to roll and tip myself but knowing how quickly the paint dries I decided to do the Western side of the yacht early in the morning and the Eastern side in the afternoon so that I was always working in the shade: it made no difference.

I've now bought a 10L pressure pot spray gun ($A109) and my Son has offered to paint it for me. (He says he can do quite a decent job).
