This document defines required procedures for substrate preparation and pressure-sensitive label application. These steps must be followed to ensure proper adhesion, durability, and long-term performance across a wide range of surface types. 

1. Storage & Conditioning 

• Store labels at approximately 72°F (22°C) and 50% relative humidity. 
• Allow labels to condition at room temperature (70°F–100°F) prior to application. 
• Surfaces must be a minimum of 50°F (10°C) at time of application. 

2. General Surface Preparation Rules 

• Assume all substrates are contaminated and require cleaning. 
• All surfaces must be clean, dry, and free of dust, oil, grease, wax, silicone, and oxidation. 
• Clean edges, seams, rivets, corners, and recesses thoroughly. 
• Apply labels immediately after cleaning to prevent re-contamination. 
• Do NOT use ammonia-based cleaners or application fluids. 
• Dry application only. 

3. Approved Cleaning Methods 

3.1 Standard Cleaning (Light Soiling) 

• Use warm water and a synthetic detergent (no waxes or lotions). 
• Rinse thoroughly and dry with lint-free towels. 

3.2 Solvent Cleaning (Heavy Oils / Grease) 

• Use approved industrial solvents compatible with the substrate. 
• Wipe dry immediately before solvent evaporates. 
• Replace cloths frequently to avoid re-depositing contaminants. 

3.3 Isopropyl Alcohol (IPA) Cleaning 

• Use undiluted rubbing alcohol or 2:1 water to IPA for industrial grade. 
• Dry wipe immediately before evaporation. 

 

3.4 Light Particulate Removal 

• Use tack cloth, vacuum, or soft broom only after prior cleaning. 

​

4. Surface-Specific Preparation Requirements 

4.1 Painted Surfaces 

• Paint must be fully cured per manufacturer specifications. 
• Avoid flat latex, chalking, silicone-containing, or oil-alkyd paints. 
• Weathered paint must be refurbished prior to cleaning. 
• Typical cleaning: Standard → Solvent (if needed) → IPA. 

4.2 Wood & Wood-Based Products 

• All wood must be sealed, primed, and painted on all sides and edges. 
• Unpainted wood is not recommended. 
• Avoid matte or flat finishes. 
• Clean as painted surfaces once sealed. 

4.3 Steel & Galvanized Steel 

• Do not apply labels to raw or rusted steel. 
• Galvanized steel must be tested and properly primed and painted. 
• Remove zinc residue prior to painting. 

4.4 Aluminum 

• Surface must be degreased and etched or chemically treated. 
• Remove oxidation before cleaning. 

4.5 Stainless Steel 

• Surface remains cold longer; ensure dry conditions. 
• Clean thoroughly using Standard → Solvent → IPA. 

4.6 Plastics (Polycarbonate, Acrylic, ABS) 

• Test for outgassing where applicable. 
• Ensure full curing prior to application. 
• Clean using Standard or IPA methods. 

4.7 Fiberglass (New or Weathered) 

• Test for outgassing prior to production. 
• Oxidized fiberglass requires aggressive cleaning. 
• Re-clean with IPA after oxidation removal. 

4.8 Glass & Non-Porous Surfaces 

• Remove contaminants using razor scraping if required. 
• Clean with IPA or approved solvent. 
• Dry completely before application. 

4.9 Concrete & Masonry 

• Surface must be sealed or painted to be non-porous. 

 

5. Label Application Procedure 

• Do not touch adhesive surface. 
• Apply from one edge to the opposite edge to prevent air entrapment. 
• Use firm thumb pressure or a soft roller. 
• Repeat pressure passes 2–3 times. 

6. Adhesive Cure & Performance 

• Initial bond is immediate but not final. 
• Maximum adhesion achieved after 24–72 hours. 
• Avoid stress, washing, or abrasion during cure. 

7. Testing & Responsibility 

• Where possible, test adhesion before placing full order. 
• Re-test when application surface changes. 
• Applicator is responsible for compatibility and preparation.
