Good storage is the cheapest way to improve your retention. Glue cures by reacting with moisture, so the aim is to keep air, heat and humidity away from it.
Before opening
- Keep it upright in a cool, dry, dark place, ideally 18 to 24°C.
- An airtight container, or a foil pouch with silica gel, keeps moisture out.
- In a hot climate (over 30°C) you can refrigerate unopened glue. Let it sit at room temperature for an hour before use.
After opening
- Reseal tightly every time and store upright.
- Keep it away from heat, direct light, air and humidity. An airtight storage container helps.
- Never put opened glue in the fridge. Condensation will ruin it.
Look after the nozzle
- Wipe the nozzle with a lint-free wipe after each use.
- Never use cotton buds, tissue or cotton pads. Cotton causes an exothermic reaction with the glue.
- Always store some spare nozzles & pins
Every time you use it
Shake the bottle with the lid on for about 10 seconds, or about 20 seconds for Pearl Black. Unshaken glue means weak bonds and poor retention.
