Silicone sealant curing time depends on the sealant chemistry (for example, neutral cure vs acetoxy cure), the joint dimensions, and site conditions.
Skin time refers to when the surface becomes tack-free. It may range from minutes to hours depending on temperature, humidity, and airflow.
Full cure usually takes longer, and thicker beads or low-humidity environments can extend curing significantly.
For project-critical sealing, follow the product TDS and verify adhesion and cure before exposing the joint to movement, rain, or cleaning.
