Introduction

Nuradeck C is a liquid-applied waterproofing membrane specifically formulated for exposed decks surfaces where a seamless, durable finish is required. Applied directly to concrete substrates, it forms a tough, elastomeric membrane that bridges minor cracks. 


Nuradeck C has been used on residential balconies and commercial walkways across New Zealand. It cures quickly and bonds well to prepared surfaces, reducing programme delays and allowing other trades to proceed. 


The finished colour is a dark green so designers may chose to overcoat it for an asthetic finish.

Considerations

  • Not suitable for vehicular traffic: Designed for foot traffic only — must not be used on driveways, car parks, or loading areas.


  • Must be installed over substrates with minimum falls to drainage as it is not intended for flat or ponding-prone areas.


  • Surface preparation critical: Substrate must be smooth, clean, dry, and free from contaminants or laitance to ensure proper adhesion and system performance.
