Tips For Getting Balloons to Last Longer in Hot Weather

16 Jun

In warm weather, latex balloons will typically only last outside for a day. As you know, sun, wind and heat will biodegrade the latex. With that said, however, there are tricks you can do to raise your odds of getting them to last more than a day outside.

1) Use only high quality balloons like Qualatex. Quality makes a huge difference.OLYMPUS DIGITAL CAMERA

2) Avoid using latex balloons whenever possible. After a few days outside, we have seen them completely disintegrate when touched.

3) Always under-inflate to allow balloons to expand when absorbing heat. We’ve found the method that works best is to over-inflate the balloon and then release air until the balloon is slightly under-inflated. This helps the balloon to breathe and expand more easily, and it is not as brittle. Under-inflating does little good unless you over-inflate first.

4) Use balloons two sizes larger than you would normally use.

5) Inflating balloons with the same temperature air as they will encounter outdoors can actually help to retain their shape better.

6) Helium does not work well outdoors in the heat. (Like all substances, helium molecules, which are less dense than air to begin with, expand when heated. This expansion of molecules causes helium to be even less dense. Steadily increased heat and pressure from the moving molecules will eventually lead to the balloon popping.)

7) While Hi-Float is used to make balloons float longer, it is not generally meant for outside use. If you want your balloons to float longer outside, you should plan on doing daily touch-up work to your balloon arrangements. Be sure to include this in your budget.

8) Balloons simply will not last outdoors overnight. As the cold air shrinks the balloons and then they expand in the sun the next day, they will pop like crazy. This can be avoided by simply bringing all balloons indoors in the evening.

9) Use white balloons as much as possible. They reflect the sun and fade less.

10) Avoid darker balloons. They will absorb heat and pop faster. If you need darker colors in your balloon decor, use ribbons to accent in a darker color.

11) Keep in mind that extreme heat speeds up the balloon leakage process. So, in temperatures close to 100 degrees, the helium will escape much faster, drastically reducing float time. If you can find a way to shade balloons, it can slow the process, somewhat.

12) Do not use water to cool down balloons. As the water dries on the latex, it becomes slightly sticky. Balloons can stick together causing them to pop as balloons they expand in the heat.

13) Mylar foil balloons last longer outdoors than latex. Just allow extra room for normal expansion and shrinkage by under-inflating. The downside is that in the hot sun the foil will not hold its color or sheen. There will be a noticeable difference by the end of the day.

14) Whenever possible, use some kind of framework to give your balloon decor structure that can withstand wind and heat. This can also be helpful for helium-filled balloons that will lose float time in the heat.

15) We’ve found that if balloons are going to pop in the heat and sun, the will usually do so within the first hour. So, you’ll have a pretty good indication of whether it will work if you set up early.

While it can be difficult to do balloon decor outdoors in the heat, it is certainly not impossible. Just use the above tips to greatly improve your odds.
