Proper surface preparation is essential for achieving maximum adhesion, durability and long-lasting sealing performance. Before application, all surfaces should be clean, dry and free from dust, oil, grease, old sealant residue or loose materials.

For best professional results, use the appropriate finishing tool or spatula to smooth the sealant immediately after application. Proper tooling helps create a clean, uniform finish while improving adhesion and overall appearance.

A properly prepared surface combined with professional tooling techniques ensures a stronger seal, smoother finish and long-lasting performance in both interior and exterior applications.
