Below zero temperatures are here already… From 360 Zolutions we would like to offer some basic advices on how to perform paint refinishing jobs under cold weather:
Low Temperature Refinish
Low temperature can produce high film thickness which that produces issues like solvent popping (tiny points caused by solvent evaporation) and orange peeling. The only way to fix these painting issues would be to remove your new paint and redo the whole project. There will also be issues with drying as car paint takes much, much longer to set in cold temperatures and is far more likely to drip and run.
A Warm Auto Spray Booth
The ideal temperature for auto painting falls between 20 and 25 degrees celsius, a temperature range we only experience for a few months out of the year. The perfect solution to such a problem is an insulated, heated, well-lit, heavily ventilated and humidity controlled paint booth.
We have to be sure to stress the importance of a well-ventilated garage or auto finishing shop. You can end up with tiny auto paint dust particles in your brand new paint and paint fumes are, of course, extremely dangerous and flammable. Wearing a dust mask or breathing mask is also mandatory.
Be Careful with Condensation
Let the car warm up in your garage for at least four or five hours. It’s equally important to make sure your paint, primers and surfaces are all stored at the right temperature and aren’t allowed to freeze. Paint mixing rooms are normally a good option for that. If car paints get cold the viscosity will increase and cause numerous issues with both painting and drying.
Use the right de-icing products to make sure your vehicle is very clean before painting. Salt residue is very difficult to see as it can leave an almost invisible layer and can cause paint defects. After cleaning the vehicle with a conventional silicone remover, be sure to use a water-based silicone remover.
Warm up compressed air
Yes, there are also equipment that can help you to warm the compressed air coming from your spray gun. Keep in mind that due to the compression, the air will naturally drop to an even lower temperature, so having this kind of heaters is a must in the winter season.
That’s all for now! Do you have any other advices that may help to achieve the perfect winter refinish?
