Make sure to securely close the lid after each use to prevent the glue from drying out. Air exposure can cause the glue to thicken and become unusable over time.
3. Use the right container
Transferring glue to a different container can introduce contaminants and moisture which may affect the glue’s adhesive properties. Stick to the original container or use an airtight container made of the same material.
4. Clean the nozzle regularly
Glue residues can clog the nozzle and affect the flow of the adhesive. Use a clean cloth or tissue to wipe the nozzle regularly to prevent blockages.
5. Don’t mix different types of glue
Each adhesive type has its own specific properties and should not be mixed together. Doing so can produce unpredictable results and weaken the integrity of the bond.
6. Check the expiration date
Adhesives have a shelf life, and expired glue may not work effectively or at all. Always check the expiration date before using the adhesive, and dispose of any expired glue properly.
By following these simple guidelines, you can maintain the effectiveness and longevity of your adhesive, ensuring that it will be ready to go when you need it for your next project.
