Spray Painting in Cold Temperatures: Tips to Beat the Cold

Spray painting in cold temperatures is not ideal, but it can be done with the right preparation. Learn how to beat the cold with these simple tips for spray painting when it's cold. The temperatures after the herbicide is applied determine the safety or damage of crops. Low temperatures can influence crop safety and weed control because of herbicides.

Plants degrade herbicides by metabolism, but plant metabolism slows down under cold or cold conditions, which extends the time needed to degrade herbicides in plants. Rapid degradation in warm conditions allows crop plants to escape damage caused by herbicides. Herbicides can be sprayed after cold temperatures during the night if daytime temperatures rise to at least 60 degrees. Because temperatures are much lower than normal, store the cans of spray paint and the items you're painting inside until you're ready to paint. Painting when it's cold inside your house requires a bit of preparatory work beyond the type of preparation you would do if you painted in the summer.

Another way to make cold spraying paint more effective is to look for options for heating the work area. While choosing a paint that works well when applied to a cold surface is a solution, you should also consider the surface temperature when you are going to apply the paint. By heating the area you are going to paint, you can heat it up so that you can spray paint onto a surface at a temperature that is more common in common paints. If you paint outside at sub-zero temperatures, you also run the risk of water-based paint freezing inside the spray gun. We have used spray paint for different crafts and DIY projects around the house, lamps, hardware and pieces of wood for outdoor use.

However, if you've decided that you'll need to spray cold, use these 6 tips to ensure you get good results and minimize headaches when spraying paint cold:

  • Store cans of spray paint and items you're painting inside until ready to paint.
  • Look for options for heating the work area.
  • Consider surface temperature when applying paint.
  • Use water-based paints that won't freeze at low temperatures.
  • Choose solvent-based paints that are better suited for spraying in cold climates.
  • Use paints with a temperature range of 32-35° F as the lowest temperature at which they can be used.
Most paints are designed to be applied to a surface that is within certain temperature parameters and, in general, the suggested temperature range is usually quite warm (above 50 degrees Fahrenheit is common in most standard household paints and dyes). Ultimately, spraying paint cold isn't ideal, as there are additional unique challenges you'll face, from ensuring that the surface is warm enough to apply the paint, to getting the material to spray effectively and storage issues. When spraying paint cold, this can create problems in obtaining a good finish of the work, since thicker material can be more difficult to atomize.
