Analysis of the top ten reasons for sealant construction failure
Analysis of the top ten reasons for sealant construction failure
Top 3 lessons learned from blood and tears:
① Improper surface treatment (accounting for 42%): Concrete moisture content > 8% causes bubbling, which must be tested with a humidity meter;
② Untested compatibility (accounting for 28%): Referring to GB/T 13477.18, EPS insulation boards must use a special primer;
③ Mixing ratio deviation (accounting for 17%): When the two-component glue A:B=10:1, the error > 5% means incomplete curing.
