TROUBLESHOOTING
Why is my caulk not curing?
Caulk can skin over while material beneath it remains soft, so appearance alone is not a cure test.
Start with the label: Identify the exact product and do not assume another formula’s remedy applies.
What to check
- Confirm the exact chemistry and variant on the tube.
- Check bead depth, temperature, humidity and ventilation.
- Look for expired, frozen or improperly stored material.
- Delay water exposure and follow the current label when the stated time has not produced a firm bead.
Before attempting a repair
Record the application time, approximate temperature, humidity, layer thickness and surface. Compare those facts with the current manufacturer instructions. If the material affects structural strength, electrical safety, pressure containment, food contact or immersion, contact the manufacturer before placing it into service.
