Spray Painting in Cold Weather: 10 Steps to Overcome the Challenges

Spray painting to a wooden frame or metal in cold weather is undoubtedly a task too difficult you might as well wait for the weather to be warm.

That’s what you might think. To be honest, you can overcome the challenges. In most cases, you HAVE to overcome the difficulties because you have no choice. Sure, the moisture and temperature will largely affect your paint application, but following the proper steps will result to:

  • No poor touch-up
  • No color uniformity issue
  • No film cracking
  • Adequate stain resistance

Ready to combat the cold weather? Here’s what you have to do:

  1. Make sure the paint is recommended to work with the temperature of the air. You can do this by asking your paint manufacturer. The paint won’t be effective as it should be if its manufacturer doesn’t recommend the paint for the specific temperature the environment has.

  1. Check the wall temperature. You also have to check the temperature of the wall using a non-contact infrared thermometer. Believe it or not, it’s almost more important than your air temperature. Normally, you shouldn’t paint if the temperature will be under 35°F for two days after you paint. But then again, it depends on the paint.

  1. Turn the heat up! Doing this is like giving your paint a helping hand when it comes to drying. Do your paint a favor and get the room as hot as you can, but see to it that you’re still comfortable, otherwise you might be helping the paint but causing yourself to suffer. Note: Before doing this, make sure you wrap everything first.

  1. Clean your spray gun the right way. This is one essential step you just can’t ignore. The cleanliness of your spray gun and its freedom from ices and dirt should be guaranteed. This time, you’ll be doing yourself a favor by doing this. No more clogging and jamming!

  1. Paint at the right time. Since the weather is cold, the sun might have a hard time sharing its light to you. This is why painting should be done between 10 a.m. and 2 p.m. During this time, more light can get through the window to make painting easier. After all, you can’t paint properly in the dark.

  1. Use a good bonding primer. Please, I’m begging you, DO NOT settle for a cheap, low-quality primer especially if you’re painting in cold weather. You’ll be surprised by how a good bonding primer helps before you apply paint.

  1. Wipe the surface properly. One of the steps you should do to overcome the usual problems is to make certain that there is no sign of frost on the surface. To do this, scrape the frost and carefully wipe the entire surface. There should be no moisture at all. It might be invisible during cold weather, so make sure you wipe the surface twice or thrice (or more!). Remember that poor painting is the result of damp. So do not rush and wipe before you paint!

  1. Read the manual. WARNING: DO NOT SKIP THIS STEP! Like I said in the first step, you should verify with the manufacturer. Knowing the exact temperature range for coating for the brand and color of paint you’ll use is a MUST.

  1. Keep the exact break time. You should mix the paint and the components at the right time.

  1. Protect the surface. Your paint will undergo a drying process, as usual. And during this time, you should ensure that the painted surface is protected. If the paint remains soft for a long time, it might tear and you wouldn’t want that.
