Best Temperature To Spray Paint Outdoors?

Best Temperature To Spray Paint OutdoorsWhen you’ve got to do some painting outside, temperature is an important factor. You want to shoot for ideal conditions (or at least as ideal as possible), so what’s the best temperature to spray paint outdoors? The best range is going to be within 50 and 90 degrees Fahrenheit… and you want to be sure that the humidity is below 85%. With the temperature, more heat is better, because your paint will dry faster. That said, don’t paint when it’s over 90 as your paint may dry too quickly and crack. By contrast, it’s under 50 degrees out, your spray paint likely won’t stick properly!

Today I’ll tell you a little more about painting and storing paint in cold weather and why you need to be very careful about it. Cold and spray paint simply do not mix well!

It’s not a good idea to spray paint when it’s very cold outside. If it’s 50 degrees or above, then you are okay, but when the temperature gets lower then you start to get all kinds of issues. For instance, at around 40 degrees, oil-based paints start to thicken up and applying even coats is going to be quite difficult.

If you are using a spray gun, it’s going to get clogged quite often, and when it is working you are still going to be at risk for things like paint bubbles. It’s really going to be better to wait until it’s warmer.

Paint also has a hard time just sticking in general when it gets cold and it’s understandable when you think a little about it. You’ve got your paints and your propellant in there and these are simply not designed for cold use.

What temperature is too cold to spray paint outside?

Is it OK to spray paint in cold weatherThe best way to avoid trouble is to stick with the ‘50+’ rule. Generally you can paint if it’s close to 50 degrees out, but you should keep in mind that you still might be opening up yourself to trouble. I learned this the hard way, myself. These paints can take a long time to dry and when you paint in the cold, there’s always a chance of a surprise cold-front coming in and the results are not pretty for your drying (now mostly frozen) mess of paints and oils.

It’s best just to wait until it’s warmer unless you absolutely have no choice. If you DO have to paint anyway, consider something quick-drying so that your paint is not vulnerable for too long a time and this can save you a lot of cursing if the weather takes a sudden turn for the worse.

Remember, if it’s too cold, your paint isn’t going to stick anyway and if it’s REALLY cold then you don’t want your aerosol cans outside in it. They could crack or even explode, so for safety’s sake just wait for warmer days and trust me on this… you’ll be happy that you did!

Speaking of exploding aerosol cans, what is the lowest temperature that you can safely store spray paint? Usually about 55 degrees is going to be the recommended amount when it comes to cold. In the summertime, you want to make sure that your aerosol spray paints are stored in the garage or somewhere comparable where the temperature is not going to exceed 80 degrees.

I should note, I don’t always follow my own advice, and I’ve had some spray paint cans freeze on me and they are often just fine once they thaw out. That said, there is still a small chance that the can will crack or worse and while it probably won’t happen when you’re in the garage (I certainly hope not!) even just the cleanup later will ensure that you don’t store your cans in the cold again.

Proper storage will avoid any problems and keep your paints looking their best, so why not just avoid any potential issues and get in the habit of storing them correctly now?

It’s really, really worth the extra effort.

In Closing

Today we’ve talked about the best temperature to spray paint outdoors and as you can see; it’s ideally going to be between 50 and 90 degrees. As far as painting when it’s cold outside, avoid doing so when the temperature drops below 50 and store your paints at 55 – 80 degrees for best results.
