Coating the Outside of Balloons Before Inflation
A quick and easy way to prevent oxidation (chalkiness) on the outside of latex balloons is to apply ULTRA HI-FLOAT coating to the outside of the balloon before inflation. This method can be used for helium- or air-filled balloons.
In addition to preventing oxidation, the external coating of HI-FLOAT increases the float life by about five times. The coating usually dries in a few minutes, but can be somewhat messy.
Here’s how to do it:
Warning: Air-filled balloons with an external coating of HI-FLOAT must be kept in a climate-controlled location. Heat and/or high humidity can cause the balloon to burst or deflate prematurely.
