How long does Advanced Silicone 2 Window & Door Sealant take to cure on Natural Stone?

Advanced Silicone 2 Window & Door Sealant takes 24 hours to fully cure on Natural Stone at 70°F and 50% RH. Temperature and humidity significantly affect this — use the calculator on this page for an adjusted estimate at your actual conditions.

How do I prepare Natural Stone before applying Advanced Silicone 2 Window & Door Sealant?

Non-porous stones (granite, basalt) need mechanical abrasion — sand with 60-grit before bonding. Porous stones (limestone, sandstone) absorb adhesive — prime with a stone consolidant first.
