Remediating a Tiled External Terrace Deck with Technokolla Rasolastik EVO and Rhino TUFF STUFF

Existing tiles on an external deck had been in place for many years. Leaks were affecting the car park below, and some areas lacked sufficient fall. A joint approach between Surtec (NZ Distributors of Technokolla Tiliing & Waterproofing System) and Rhino Linings retained sound tiles where possible, and corrected localised falls. It introduced a reinforced waterproofing layer prior to a sprayed, trafficable finish.

Design notes:

  • Confirm falls to drains, outlet capacity and the movement joint plan before starting.
  • Identify any drummy, cracked, or loose tiles for replacement, and keep the designed joints clean and open.
  • Allow for screeding and ramping where ponding was evident, then applied full-surface reinforcement and waterproofing before a trafficable top system.

System build-up and QA sequence:

  1. Degrease and decontaminate, then diamond-grind to remove glaze and open grout joints, vacuum clean.
  2. Repair and re-bond tiles as required, install Technokolla Monokoronos screed to correct local levels and ramps
  3. Spot-prime porous areas with Technokolla Primer T Plus, and non-porous details with Technokolla Primer-101 Plus
  4. Apply Technokolla Rasolastik EVO in two coats and fully embed Techno Mesh Tapas 40 GSM, with 50 mm laps and 150 mm upstands.
  5. Rhino Linings primed and spray-applied Rhino TUFF STUFF to the specified thickness, then applied UV topcoat and slip-textured finish.

Compliance and support

Rhino TUFF STUFF is a rapid-curing 100% solids polyurethane (zero VOCs). It is a Class III waterproof membrane to AS/NZ 4858:2004, with typical uses including rooftops, podiums and balconies. CSIRO reporting records Class III high extensibility (431% control strain), a cyclic movement pass at 4mm extension for 50 cycles with no fatigue cracking, and water vapour transmission of 4.09 g/SQM/24 h to ASTM E96.

Warranties and responsibilities

Surtec provides the product and system warranty for the Technokolla component, covering preparation, any Technokolla Monokronos screeding to correct levels, Techno Mesh Tapas 40 GSM reinforcement, and the two-coat Techno Rasolastik EVO, BRANZ appraised waterproofing membrane. Rhino Linings provides its warranty for the Rhino TUFF STUFF system, including primer, sprayed build to the specified thickness, and the topcoat, giving clear split responsibility with joined-up technical support.
