Sealant purchasing guide: Choose the right glue to stick firmly
There are many types of sealants, and choosing the wrong one may cause leakage and cracking! Check 3 points before buying:
Usage scenario: choose mildew-proof glue (such as silicone glue) for kitchen and bathroom, weather-resistant glue for door and window caulking, and neutral glue for stone to avoid corrosion.
Performance parameters: pay attention to curing time (quick-drying type is suitable for repair), elastic modulus (high elasticity and displacement resistance), temperature range (-40℃~150℃ is more universal).
Tips to avoid pits:
Acidic glue (vinegar smell) will corrode metal, and neutral glue is more versatile;
Operation suggestions: calculate the amount in advance (1 stick of glue is about 6 meters * 6mm glue seam), and buy 1 more for backup.
