A flexible, single component, moisture curing modified polyurethane liquid membrane designed for all kinds of waterproofing projects.

Rooftex is UV stable and cures within hours to produce a tough, seam-free, rubber-like membrane of exceptional elasticity, which will not crack or craze. The membrane is designed as a long-term solution for new or old roofing and can be applied to a wide range of surfaces, including failed membranes, asbestos, corrugated sheeting and concrete.

The membrane is also designed for use in wet areas such as bathrooms, swimming pools, balconies, planters, podiums and for structural foundations (specify in section J30).


  • Primer: Rooftex Urethane Primer to cementitious/ porous surfaces or Rooftex GP Primer to existing bitumen, asphalt and felt based substrates. Coverage per coat: 6–8 m²/litre
  • Membrane coat: Conren Rooftex cold applied directly from drum by brush, roller or squeegee.
