One component moisture curing liquid polyurethane membrane

TECHNONICOL ULTRATHANE ECO is one component moisture curing liquid made up from pure polyurethane, which once cured forms a continuous elastic membrane, without any joints, overlapping or any integrated mesh required. It can be applied by brush, squeegee, roller, or airless spray. Roller application is necessary for reinforced systems.

The product is available in grey, white, other requested colors.


Waterproofing systems with or without reinforcement for:

  • Roofs, terraces, and balconies.
  • Tanks, channels, pipelines.
  • Renewing old membranes.
  • Parking and sport areas.
  • Wet areas.
  • Bridge decks, overpasses, and podiums.

The product is moisture curing. The rapidity of hardening is strongly influenced by relative environmental humidity.
The speed of reaching the "dry to the touch" condition depends on the amount of ACCELERANT.
- dry to the touch 6-8 hours
- insensitive to rain 8 hours
- over-application 24 hours
- completely cured 7 days
Hardening at 20°C, 35 % R.H.
