Application Instructions
Clean and remove dust, oil, and loose particles.
Shake the can vigorously for 30–60 seconds.
Moisten the surface lightly with water.

Hold the can upside down during application.
Fill joints approximately 40–50%, allowing room for expansion.
Allow foam to cure completely before trimming.
Protect cured foam from prolonged UV exposure using paint, plaster, or sealant.
