Many people have started spray painting nowadays. For some, it’s a hobby, while for others it’s a way of saving some money. Spray painting isn’t a hard job, but spray painting in cold weather might turn into a disaster, especially when you’re painting the interior of the kitchen cabinet or a car.
Painting during winter or in the cold weather is many a time unavoidable. Most remodelers and home builders try that everything gets done before the year’s end, but timing is not right. Temperature range for the cold weather is from 2 to 10°C.Jinwei Car paint knows, now all you’re thinking is how to spray paint in such cold weather, right?
It’s necessary to understand that how the paint application gets affected by low temperatures and how the performance, characteristics and drying pattern of the paint gets changes.
Painting gets affected due to cold weather because oil and alkyd paints are based on the resins and natural oils which get more vicious under low temperatures. That’s the reason some paints at the subzero temperatures or in the cold weather become semi-solid or very thick; which might need excessive thinning.
Although the latex paints get frozen at the low temperatures, need some particular additives to thaw resistance or improve freeze in latex paints. You can even use same additives in hot weather to do a painting to make the rolling and brushing process easier.
Latex paints get solely affected by volatile additives and slower evaporation water rate under low temperatures.
As I explained earlier, latex paints might thaw and freeze, if not treated properly. How would you paint if it had gone through many thaw/freeze cycles? Well, in that case, if you still want to use the old gallon of latex, then you must first check if it has lumps in or not.
If you observe such consistency, then it’s the sign that the paint is not usable anymore and you must discard it. Manufacturing of latex paints is done in such a way that it can undergo several thaw/freeze cycles, but the moment you find lumps in it, you must discard it.
Compared to latex-based paints, oil-based paints are more resistant, and they get frozen at the lower temperatures.
Painting in the cold weather may bring some additional problems like:
Drying period might slow down because of the heavy film
Color uniformity is quite poor
Paints will need more time for mixing
Water spots, especially in Latex Paints
Improper formation of film causes powdery film
Base coat might look darker than the touch-up coat
Paint coverage reduces due to excessive building of film
If the temperature goes below 4°C, avoid use of oil-based paints
Paint film will get thick, and it will cause issues like creating bubbles/bumps when applied
Spray gun does not work the way it was supposed to and gets clogged easily
Runs and drips in the paints are common if you paint in the cold weather
Make certain that spray gun that you’re going to use is clear because chances are ice might get struck into the gun during the cold weather. Cleaning the gun before will help you avoid problems like jamming or clogging later.
Make sure the surface of the object you’re going to paint is clean. Any moisture left on the surface will cause problems.
Scrap away the frost which might be formed on the surface and wipe clean.. Look for the moisture. Make certain you look very good. Otherwise, you’ll end up having poor paintwork.
Don’t forget to follow instructions mentioned in the manual. Many manuals include some guide to painting in the rough weather. So it’s better to check before you start as not every spray paints react same at such low temperatures.
Protect the object’s surface during coating. While the paint gets dried, you need to make sure that the painted surface is protected till it gets dried completely.
Keep your eye on the temperature. You must be aware of what you’re dealing with before you begin to paint your car or wall or anything. So it’s better to start with checking the temperature first.
Don’t forget to inspect your paint before you start. Don’t forget to do the test patch first somewhere.
Here are some of the outcomes which you may get if painting in the cold weather:
Insufficient stain resistance
Unequal color uniformity
Poor quality touch up
If your car needs to be revitalized or you’re planning to add some style to the car, then painting your car wheels is the magic touch you need. You can get it done in the shop, but you know you can do it yourself too. Before beginning the painting, make certain to:
Verify that the paint recommended by the paint manufacturer is suitable for your particular temperatures.
Check air temperature as well as the temperature of the wall with the non-contact infrared thermometer.
Turn up the heat to help the paint get dried faster.
Select the right brush and roller depending on paint consistency and temperature.
Start painting in daylight, say at 10 a.m., as the light on cold days will help you get a clear and better view.
Set up the scaffolding, wrap up everything and heat particular area up.
Use Jinwei Car Refinish coatings that are suitable for cold weather and if the temperature goes below 2°C, do not paint for at least two days.
Use a nice bonding primer before you apply the paint.
Moisture and temperature are the most important part of any paint application. Spray cans are better options to paint compared to the spray guns. The very first thing to keep in mind when doing spray painting at the lower temperatures is that excess moisture, any ice or snow in the air means paint will take more time to get dried.
So, before you start doing spray paint make sure you keep all the above-mentioned aspects in mind, as they will make your painting easier and safer.
