SURFACE PREPARATION

All surfaces must be clean, dry, and free of contaminants including dust, oil, loose coatings, and debris.

• Pressure wash recommended (minimum 2000 PSI with fan tip)
• Mildew should be treated and rinsed thoroughly
• Cracks and defects should be repaired prior to coating

Substrate Guidelines:

• Masonry: Cure minimum 30 days; prime before coating
• Metal: Clean rust and prime appropriately
• EPDM: Use compatible primer/cleaner
• PVC / Hypalon / aged TPO: Use approved primer
• Polyurethane foam: Apply directly within 24 hours of installation
• Asphalt surfaces: Use appropriate base coats
• Other substrates: Follow approved primer guidelines

APPLICATION

Can be applied by brush, roller, or spray on clean, dry surfaces.

• Surface must be at least 75°F for spraying
• Each coat must be fully dry before applying additional layers
• Contaminated surfaces must be cleaned prior to recoating

APPLICATION PROPERTIES

• Coverage Yield: 1 gal per 100 sq ft (approx. 8.8 dry mils)
• Dry Time: ~90 minutes at 75°F / 50% humidity
• Recoat Window: 6+ hours
• Full Cure: ~30 days

COVERAGE RATE

Apply at approximately:

• 1.5 gallons per 100 sq ft (24 wet mils)

Surface texture and environmental conditions may affect final thickness.

ENVIRONMENTAL CONDITIONS

• Do not apply below 50°F or if temperatures may drop below 32°F within 24 hours
• Avoid application when rain or dew is expected before drying
• High humidity and cool temperatures may extend cure time
• Multiple thin coats may be required in marginal conditions

LIMITATIONS

• Not recommended for slopes under 1/8 in 12
• Not suitable for ponded water conditions
• Must be fully dry before exposure to moisture
• Not intended as a vapor barrier or thermal barrier
• Cure requires full water evaporation

SAFE PRACTICES

For professional use only. Users should be familiar with proper handling, safety procedures, and application methods prior to use.
