I've got some exterior painting on woodwork that I'd like to get done before Christmas.
I'm in Shropshire, current temp is around 7C, and the forecast is showing a drop to sub zero for around a week.
The paint is Exterior Weathershield and says 'don't use in extreme temps'.
I've not prepped yet, and that will take today. I'll then undercoat, which dries fast. But the gloss takes 24 hours. Didn't go for Quick Drying as it doesn't last as long, or weather as well.
So how cold is too cold? Should I push on and paint through the frost?
+8 is the lowest the paint I bought yesterday states (got to stay above that until dry).
Can you google it and see if you can find more information?
Is it solvent or water based? If it's water based then anything approaching zero is a bad idea. Even with solvent based I wouldn't be painting if it was less than 10°C. While you might get away with it the performance of paints applied in cold humid conditions is significantly worse than that applied in warm dry conditions.
Anything below 10ºC is considered cold and we are required to do specific testing. Anything below 5°C is a real challenge and usually involves reformulating the paint. Anything below 0°C is going to be very expensive as it will require specialist materials.
When the paint freezes rather than dries?
