How to use

Clean and dry the surface thoroughly to ensure proper adhesion. Cut the tape to the required length, peel off the protective backing and apply firmly to the surface, smoothing out any bubbles or wrinkles. For best adhesion and handling, apply at temperatures above 50°F (10°C). Allow the adhesive to set before exposing the tape to heavy traffic or extreme conditions.

Recommendations

Regularly inspect the tape for signs of wear, damage or loss of reflectivity, especially in high-traffic areas, and replace sections as necessary to maintain visibility and compliance with safety requirements.
