Description  
Use Duram 195 for: Waterproofing wet areas, decks, balconies, and below-ground structures where a durable, flexible, and seamless membrane is required.

Duram 195 is a premium, single-pack, moisture-curing polyurethane waterproofing membrane designed for professional use in non-UV exposed areas. It cures to form a tough, seamless, and elastomeric (Class III) membrane, providing long-term waterproofing protection. Its self-leveling capability and easy application make it ideal for various applications, including wet areas, decks, and below-ground structures. When top-coated with Multithane ATC, it can also be used in exposed areas.

Key Features of Duram 195

  • Single Pack, Easy Application: No mixing required, simplifying the application process and reducing waste.
  • Rapid Cure: Cures within 24 hours, allowing for faster project completion.
  • Permanently Flexible: Maintains flexibility (Class III), accommodating substrate movement and preventing cracking.
  • Seamless Membrane: Forms a 100% bonded, seamless membrane, eliminating joints and laps for superior waterproofing.
  • Excellent Chemical Resistance: Suitable for demanding waterproofing applications and permanent immersion.
  • High Strength and Puncture Resistance: Provides a durable and robust waterproofing layer.
  • Low VOC and Green Star Compliant: Meets environmental criteria, making it a sustainable choice.

Technical Overview

Duram 195 is formulated with UV stabilizers, absorbers, and antioxidants to enhance its UV protection and stability. It bonds well to most primed building substrates and is suitable for both above and below-ground applications. Its self-leveling properties ensure a smooth, even finish, while its elastomeric nature accommodates substrate movement.

Chemical Properties: Moisture-curing polyurethane membrane with UV stabilizers, absorbers, and antioxidants.

Application Temperature Range: 10°C to 35°C (50°F to 95°F). Ensure the substrate surface temperature is within this range for optimal adhesion.

Application Information

  • Required Tools: Brush, roller, broom, or squeegee, Duram Resiflex FC sealant, Duram Leak-Seal Tape (for joints and cracks), Duram Solvent (for cleanup).
  • Trade-Specific Tips: Ensure surfaces are thoroughly primed with Duram Primeseal MC or SP. Pay close attention to detailing corners, joints, and cracks using Duram Resiflex FC and Leak-Seal Tape. Apply two coats for optimal thickness and performance.
  • Common Issues and Solutions: Avoid applying to damp surfaces to prevent gassing and bubbling. Ensure proper surface preparation to avoid adhesion failures. Use Duram Solvent for immediate cleanup of spills and equipment.

Storage and Shelf Life

  • Storage Requirements: Keep in a cool, dry place away from heat, flame, or combustible materials.
  • Shelf Life Information: 6 months in unopened container, best used within that period.
  • Temperature Considerations: Store within recommended temperature ranges to maintain product integrity.

Certifications

  • AS4654.1 2012: Waterproofing membranes for external above-ground use (when top-coated with Multithane ATC).
  • Green Star environmental criteria compliant.
Common Questions  

Frequently Asked Questions About Duram 195

Q: Can Duram 195 be used in exposed areas?

A: Yes, but only when top-coated with Duram Multithane ATC to provide UV protection. Duram 195 itself is not designed for long-term direct UV exposure.

Q: What surfaces can Duram 195 be applied to?

A: Duram 195 is compatible with a wide range of surfaces, including concrete, cement render, block work, masonry, FC sheeting, metal (when primed), and timber (when primed). Proper priming is essential.

Q: How do I prepare surfaces for Duram 195 application?

A: Surfaces must be sound, stable, dry, and clean. Prime surfaces with Duram Primeseal MC or SP. Fill blowholes and imperfections with Duram Resiflex FC. Detail corners, joints, and cracks with Resiflex FC and Leak-Seal Tape.

Q: What is the correct application thickness for Duram 195?

A: The dry film thickness (DFT) should be 1.5mm for floors and tanking areas, applied in two coats (0.75L/m² per coat). For vertical surfaces, 1.0mm DFT is required. For water-resistant non-tanking walls, 0.5mm DFT is sufficient.

Q: How do I clean up Duram 195?

A: Use Duram Solvent to clean spills and equipment immediately. Avoid spills on porous surfaces and carpets. Allow the product to cure before attempting to remove it from carpets.

How To Apply  

How to apply Duram 195:

  1. Ensure surfaces are sound, clean, and dry. Prime with Duram Primeseal MC or SP.
  2. Detail corners, joints, and cracks with Duram Resiflex FC and Duram Leak-Seal Tape.
  3. Apply Duram 195 by brush, roller, broom, or squeegee in two coats, allowing 6-24 hours between coats.
  4. Ensure a minimum dry film thickness of 1.5mm for floors and tanking areas, and 1.0mm for vertical surfaces.
  5. For exposed areas, top-coat with Duram Multithane ATC after Duram 195 has cured.
Limitations and Safety Info  

Duram 195 limitations:

  • Not designed for long-term direct UV exposure; requires top-coating with Multithane ATC for exposed areas.
  • Not designed as a trafficable membrane, though infrequent maintenance foot traffic is acceptable.
  • Not suitable for direct and prolonged contact with chlorine concentrations above 10 ppm.
  • Cannot be applied to damp surfaces; surfaces must be dry.
  • Direct tile adhesion is not advised; seek Duram technical advice for specific applications.

Safety precautions when using Duram 195:

  • Ventilation: Use in well-ventilated areas as it is solvent-based.
  • Flammability: Keep away from ignition sources as the uncured product is combustible.
