How to Make Helium Balloons Last Longer

Balloons add a festive touch to any occasion, and helium-filled balloons, in particular, create an enchanting atmosphere. However, it can be disappointing when these balloons start to deflate and lose their magic too soon. If you want your helium balloons to last longer and keep the celebration going, here are some effective tips and tricks to help you achieve just that.

How to Make Helium Balloons Last Longer

Helium balloons bring joy and excitement to various events, from birthday parties to weddings. However, they have a limited lifespan, and it can be disheartening to see them deflate prematurely. Fortunately, there are several techniques you can employ to extend the longevity of helium balloons. By following these tips, you can enjoy their vibrant presence for a longer period of time.

Use Hi-Float

One of the most effective ways to make helium balloons last longer is by using a product called Hi-Float. Hi-Float is a specially formulated liquid solution that is applied to the inside of latex helium-filled balloons. It creates a thin coating that helps to hold in the helium, significantly prolonging the balloon’s float time. By using Hi-Float, you can extend the life of your balloons by up to 25 times.

Avoid Sunlight and Heat

Helium balloons are sensitive to sunlight and heat. Exposing them to direct sunlight or extreme heat can cause the helium inside to expand rapidly, leading to deflation. To ensure your balloons last longer, keep them in a climate-controlled room away from windows or sources of heat. This will help maintain a stable environment and preserve the integrity of the balloons.

Inflate Them Only to 90% Capacity

Helium molecules expand when exposed to heat, causing balloons to deflate faster. To counteract this, inflate your balloons to only 90% of their maximum capacity. By leaving a little room for the helium to expand, you can slow down the deflation process and enjoy longer-lasting balloons.

Use a 60/40 Mix to Inflate Your Balloons

Another effective technique to increase the lifespan of helium balloons is by using a 60/40 mix of helium and air. Instead of filling your balloons with pure helium, combine 60% helium and 40% air. This mixture reduces the rate of helium escape and helps your balloons stay afloat for an extended period. Moreover, using air is more cost-effective than using pure helium, allowing you to save money without compromising the floating time.

Utilize Firm-Set Hairspray

Did you know that a common household item like firm-set hairspray can contribute to the longevity of your helium-filled balloons? By lightly spraying the exterior of the balloons with firm-set hairspray, you create a protective barrier that slows down the escape of helium. This simple method can help your balloons stay inflated and retain their charm for longer.


With these practical tips, you can extend the life of your helium balloons and enjoy their vibrant presence for an extended period. Using Hi-Float, avoiding direct sunlight and heat, inflating them to 90% capacity, utilizing a 60/40 mix of helium and air, and applying firm-set hairspray are effective strategies to make your helium balloons last longer. Incorporate these techniques into your balloon preparations and make your next celebration an unforgettable experience.


Q1: Can I use Hi-Float on all types of balloons? A: Hi-Float is specifically designed for use with latex balloons. It is not recommended for foil or Mylar balloons.

Q2: How long can I expect my helium balloons to last with Hi-Float? A: When properly applied, Hi-Float can extend the float time of latex balloons by up to 8 to 12 hours (2-4x longer) their usual duration.

Q3: Will the 60/40 helium-air mix affect the floating time significantly? A: While the 60/40 mix may slightly reduce the floating time compared to pure helium, it is still an effective way to increase the overall lifespan of your balloons.

Q4: How often should I apply firm-set hairspray to my helium balloons? A: It is recommended to apply firm-set hairspray to your balloons shortly before the event or celebration. Reapplication may be necessary if the balloons are exposed to outdoor conditions or high temperatures.

Q5: Can I reuse helium balloons that have been treated with Hi-Float? A: Hi-Float is a one-time-use product. Once the event is over, it is best to dispose of the balloons responsibly.
