Helium balloons are a wonderful addition to any party or event. But how do you ensure they stay afloat longer? There's nothing more disappointing than balloons that fall to the ground within a few hours. Fortunately, there are some smart tricks to significantly extend the float time of your balloons. In this blog, we share the best tips so your balloons will stay happily floating all day (and maybe even for days afterward)!

How long do filled balloons last?

Many people wonder: "How long do filled balloons last?", "How long does a helium balloon float?", "How quickly does a helium balloon deflate?", "Can you inflate balloons a day in advance?" or "How do you keep a helium balloon afloat?". The answer depends on the type of balloon and what it is filled with. Helium-filled latex balloons (standard size of 30 cm) typically float for 14 to 16 hours. Helium-filled foil balloons often float for days to weeks due to their non-porous material. Latex balloons filled with air do not float but remain intact for several weeks. They lose air more slowly than helium.

Do you want your balloons to stay afloat longer and remain beautiful all day? Then it's essential to know which choices you can make and how you can extend the float time with smart techniques. Below you will find some effective tips to keep your balloons floating as long as possible.

1. Use foil balloons instead of latex balloons

Foil balloons naturally float much longer than latex balloons. This is because foil balloons are less porous, which means the helium escapes more slowly. Foil balloons can float for days to even weeks, while latex balloons without additional treatment often float for only 14 to 16 hours.

2. Treat latex balloons with Hi-Float

Hi-Float is a special substance that coats the inside of latex balloons with a thin film. This coating prevents helium from escaping quickly. By treating your balloons with Hi-Float before filling them with helium, latex balloons can float for 2 to 5 days instead of 12-24 hours. Use a pump or special dispenser to apply the correct amount of Hi-Float. Gently massage the balloon to spread the substance evenly before filling it with helium.

3. Inflate the balloons just before use

Inflate the balloons with helium as close as possible to when you need them. The longer they are filled in advance, the greater the chance that the helium will escape. This is especially important for latex balloons, as they lose helium quickly without Hi-Float.

4. Avoid extreme temperatures

Helium expands in heat and contracts in cold. This means balloons can pop in hot weather and shrink in cold weather. Make sure to store the balloons at room temperature. Do not place them in direct sunlight or freezing temperatures.

5. Choose the right balloon size

The larger the balloon, the longer it floats. Large balloons can contain more helium, resulting in a longer float time. Balloons of 30 cm or larger are ideal if you want a longer float time.

6. Avoid friction and sharp objects

Balloons can puncture due to friction or sharp objects. Make sure they do not rub against walls, branches, or rough surfaces. Foil balloons are less vulnerable than latex balloons, but it is always a good idea to be cautious.

7. Use a balloon net or balloon weight

Make sure the balloons do not fly away. Use balloon nets (for larger quantities) or balloon weights to keep them in place. This is especially useful for outdoor locations where the wind is a factor.

8. Avoid moisture and rain

Do not use helium balloons in the rain. The water that lands on the balloons makes them heavy, causing them to sink prematurely. Additionally, latex balloons can become more porous when wet, allowing helium to escape faster.

9. Avoid confetti, LED lights, or cards

Helium balloons with confetti inside, LED lights, or a card attached make the balloon heavier, significantly reducing the float time. These extra elements add weight to the balloon, causing the helium to have less lifting power. Do you still want a special look with confetti or lighting? Then consider using a larger balloon that can hold more helium and therefore provide more lifting capacity.

Summary

Do you want your balloons to float longer? Choose foil balloons or treat latex balloons with Hi-Float. Inflate them at the last moment, avoid extreme temperatures, and use balloon weights. By following these simple steps, your helium balloons will float longer, leaving a lasting impression on your guests.
