How to Choose Glass Sealant Correctly

1. Define the purpose: structural parts use structural sealant, joint sealing uses weatherproof sealant, kitchen/bathroom uses anti-mold sealant — different purposes, different products.

2. Check performance: verify movement capability, bonding strength, tack-free time and temperature range meet project needs.

3. Choose reliable brands: select qualified manufacturers with good reputation, check that products pass national standard testing, and note model, production date and expiry on packaging.

4. Correct application: substrates must be clean and dry, application temperature 5℃~40℃, and sealant must fully cure before bearing loads.

5. Storage: store sealants in a cool, dry place away from direct sunlight and use before expiry.
