Avoid Exposure to Sunlight

Sunlight speeds the drying process of adhesives because sunlight makes the molecules in glue move faster. The result is glue bonding quickly. Storing in a cool area away from sunlight will solve the problem.

Store in the Original Container

The best place to keep the adhesive is its original container. So, do not try to move it out of the container.

Wipe the Nozzle After Use
