Technical Overview
Everflex Supaprime is formulated with a moisture-curing polyurethane system, providing a robust primer that enhances the bond between substrates and subsequent coatings. Its low viscosity and fast-drying properties make it an efficient solution for various construction and waterproofing applications.
Chemical Properties: Moisture-curing polyurethane primer with low viscosity for deep substrate penetration.
Application Temperature Range: 5°C to 35°C (41°F to 95°F). Apply within this range to ensure proper curing and adhesion, avoiding extreme temperatures that can affect performance.
Application Information
-
Required Tools: Brush, roller, spray equipment.
-
Trade-Specific Tips: Ensure surfaces are thoroughly clean and dry before application. For highly porous substrates, a second coat may be necessary. Allow the primer to stay wet on the surface for 2 minutes for optimal penetration.
-
Common Issues and Solutions: If the substrate is damp or contaminated, adhesion may be compromised. Ensure proper surface preparation. For slow drying times, verify ambient temperature and humidity levels.
Storage and Shelf Life
-
Storage Requirements: Store in a cool, dry place between 5°C and 35°C (41°F and 95°F).
-
Shelf Life Information: 12 months from the date of manufacture.
-
Temperature Considerations: Avoid storing in extreme temperatures to maintain product integrity.
