Application tips for best results

Prepare surfaces by cleaning and drying thoroughly. Apply with the squeeze tube for controlled placement, then smooth the bead for a clean finish. Allow full cure time—typically 24 hours—before exposing the seal to moisture or stress. For optimal results, follow local guidelines and project-specific recommendations.
