I have a question about : RAPTOR LINER
U-Pol note:
do not use in extreme cold or hot temperatures.....
but what is EXTREME ? extreme cold is on the Moon and extreme hot on the Sun...........
I can spray Raptor Liner Tintable at a temperature of +1° to +5° Celsius ? ( 34°F - 41°F ) ??
I know that it takes longer to dry, but is that possible?
It is useful to preheat in a water bath ?, heat up to +25° Celsius (77°F) and then "Shoot" ?

Even if they say you can, I simply would not spray anything under 15c ambient as you just won't get the best results. I realize you need it done to move on, but it would be a shame to skimp on the paint now to move thingsfaster.

Thanks for the information.
I am allowed to use the hall of my neighbor for a few days (25m x 14m )
Now it can go on next week

that's the answer from U-POL
thx to U-POL
Hi Jürgen,
Ideal cure temperature is 10°C+
Cold temperatures can have a significant impact on the curing of polyurethane coatings. As temperatures drop, the curing process slows down and can even stop when temperatures drop below 10°C in a shop/garage. These conditions can result in a finish that may eventually dry, but will exhibit reduced durability, gloss, and repairability. Therefore, it is important to ensure your products, your substrate, and ambient spray temperature are all above 10°C to insure proper curing of your paint film.
Applying paint in cold conditions:
A very important aspect of winter car painting to remember is the presence of condensation. If you bring a cold vehicle in to a warm garage you’ll likely end up with a thin layer of condensation forming across the body of the car. The thin, almost unnoticeable layer of water will make for adhesion issues and auto paint flaws. This is just like the condensation which forms on the outside of a cold glass on a warm day.
The best way to avoid any issues with condensation is to allow the cold car to warm up in your shop/garage for at least four or five hours, though allowing for more time certainly isn’t a bad idea. It’s equally important to make sure your polyurethane paint, primers and surfaces are all stored at the right temperature and aren’t allowed to freeze. If polyurethane paints get cold the viscosity will increase and cause numerous issues with both painting and drying.
I hope this is of assistance.
