Use Everflex Supaprime for: Enhancing adhesion of sealants and waterproof membranes on concrete, timber, masonry, and other porous and non-porous surfaces.

Everflex Supaprime is a moisture-curing polyurethane primer that offers exceptional adhesion and fast drying times. Its low viscosity allows for deep penetration into substrates, ensuring a strong and durable bond. Suitable for both internal and external applications, this primer is ideal for preparing surfaces before applying waterproof membranes, polyurethane, and MS sealants. It's designed to resist mould and mildew, making it suitable for hot and humid environments.

Key Features of Everflex Supaprime

  • Fast Drying: Reduces waiting time, allowing for quicker application of subsequent coatings and sealants.
  • Excellent Adhesion: Provides a strong bond on most common porous building materials, ensuring long-lasting performance.
  • Low Viscosity: Enables deep penetration into substrates, enhancing adhesion and durability.
  • Ready to Use: Single-component formulation simplifies application and reduces waste.
  • Mould and Mildew Resistant: Suitable for use in hot and humid environments, maintaining integrity over time.

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.

Certifications

  • Standard MVT (ASTM E 96-80) perms: 0.032

Frequently Asked Questions About Everflex Supaprime

Q: Can Everflex Supaprime be used on damp surfaces?

A: No, Everflex Supaprime should not be applied to damp, wet, or contaminated substrates. Ensure surfaces are dry and clean before application to ensure proper adhesion.

Q: How long does Everflex Supaprime take to dry?

A: Everflex Supaprime dries to a translucent film in approximately 1 hour at 23°C (73°F). Cure times may vary depending on atmospheric conditions and substrate porosity.

Q: Is Everflex Supaprime suitable for external applications?

A: Yes, Everflex Supaprime is suitable for both internal and external applications. However, it has limited UV resistance and must be overcoated for long-term UV exposure.

Q: What types of surfaces are compatible with Everflex Supaprime?

A: Everflex Supaprime is compatible with porous and non-porous substrates, including concrete, masonry, timber, cement sheeting, and plasterboard.

Q: How do I determine if a substrate is porous or non-porous?

A: Dispense water onto the substrate. If the water absorbs in less than two minutes, the substrate is porous. If the water remains, it is non-porous.

Q: What is the coverage rate of Everflex Supaprime?

A: The coverage rate is approximately 5 to 10 square meters per litre, depending on the substrate's porosity.

Q: What safety precautions should I take when using Everflex Supaprime?

A: Wear appropriate PPE, including gloves, eye protection, and respiratory protection if needed. Ensure adequate ventilation. Refer to the Safety Data Sheet (SDS) for detailed safety information.

Use Everflex Supaprime for:

  • Priming porous substrates before applying waterproof membranes.
  • Enhancing the bond of polyurethane, MS, and silicone sealants and adhesives.
  • Priming timber and masonry surfaces.
  • Preparing surfaces for Everflex waterproof membranes.

Why Use Everflex Supaprime:

  • Fast drying: Reduces project timelines with quick drying times.
  • Excellent adhesion: Ensures a strong, durable bond on various substrates.
  • Deep penetration: Low viscosity allows deep penetration for enhanced adhesion.
  • Ease of use: Single-component and ready to use, simplifying application.
  • Durability: Resists mould and mildew in humid environments.

How to apply Everflex Supaprime:

  1. Ensure the surface is clean, dry, and free of contaminants.
  2. Apply using a brush, roller, or spray.
  3. Allow the primer to dry for approximately 1 hour before applying sealants or waterproofing membranes.
  4. If the substrate is highly porous, a second coat may be required.

Everflex Supaprime limitations:

  • Not designed for long-term UV exposure – must be overcoated
  • Do not apply in temperatures below 10°C or above 35°C
  • Not suitable for damp or wet substrates
  • Not recommended for areas with hydrostatic pressure

Safety precautions when using Everflex Supaprime:

  • Personal Protective Equipment: Wear gloves, safety goggles, and a respirator
  • Ventilation: Ensure adequate ventilation during application
  • Handling: Avoid skin and eye contact; wash hands thoroughly after use

Everflex Supaprime can be used on the following substrates:

  • Concrete (after 28 days curing).
  • 3:1 sand cement screed or C-Bed.
  • Masonry/render (after 4 days curing).
  • Cement sheeting/underlay/weatherboard/blue board.
  • Pre-cast concrete (after release agent removal).
  • Wet area plasterboard/Villaboard.
  • Timber flooring (structural plywood Type A).
