Installation Notes

Surface should be clean, dry, and free of dust or grease before applying adhesive-backed characters to ensure proper adhesion. No special tools are required for installation. For outdoor address marking, local municipality or building codes may specify minimum character size and placement height - verify requirements before installation. Avoid applying in temperatures below manufacturer-recommended minimums for adhesive bonding.
