ParaFlex FV Mastic

ParaFlex FV Mastic is a one component fibre-reinforced MS-Polymer for the sealing of difficult and inaccessible roof details and connections. An additional mat reinforcement is not necessary.

ParaFlex FV Mastic is non-fading and UV-stable and therefore resistant to aging and also flexible at low temperatures. The material is one component and therefore more economical.

ParaFlex FV Mastic is used for repairs to all connections and penetrations on roofs and similar components that can only be reached with great difficulty and are made with fleece-reinforced liquid applied waterproofing membranes.


ParaFlex FV Mastic adheres to almost any surface and the connections are permanently waterproof. Exceptions are substrates made of PE, PP, TPO, FPO, silicone and Teflon.

The substrate must be clean and dry, free of oil and grease, and prepared with ParaFlex Cleaner.

ParaFlex FV Mastic should be stored and applied at between +15°C to +25°C, and applied to a substrate that has a surface temperature of between +5°C to +35°C.
