​Important Installation & Compatibility Note

It performs best when the entire fixture base is fully encapsulated, creating a seamless, continuous protective barrier.

• ​ Application Window: Do not apply over recently installed alternative sealants that are less than 120 days old, as the curing process of fresh materials can interfere with proper adhesion.
