Latex is a natural rubber full of microscopic pores. Helium atoms are small enough to leak through those pores in a matter of hours, which is why an untreated 11-inch balloon often droops the next morning.
HiFloat is pumped in before the helium. It dries as a thin film on the inner wall and cuts the leak dramatically. We use it on latex that must still look good the next day — hotel surprises, next-morning reveals, multi-day events. Foil balloons already hold helium well, so they do not need the gel.
- Only for latex helium balloons, never for foil or air-filled latex
- Typical float: about 8–16 hours without HiFloat, 1–3 days with it, indoors
- The balloon feels slightly heavier and must dry a few minutes after treatment
- Heat, sun and outdoor wind still shorten the life, even with HiFloat
- Ask the operator to add HiFloat when you place a latex set for the next day
If the party is tomorrow and you want latex, say so when ordering from the catalogue.
