Installation

The surface must be free from dirt, moisture, ice, grease and other materials which could reduce the adhesion of the tape. Tyvek® FlexWrap is to be installed when dry and at temperatures above 0 °C. A primer may be used for application temperatures below 0 °C and non-ideal surface conditions.

• Properly position Tyvek® FlexWrap around the surface to seal.
• Minimise wrinkles and bubbles by smoothing the surface and by repositioning as necessary.
• Apply pressure by hand along the entire surface to achieve a good bond to the substrate. (After pressure has been applied repositioning may be difficult.)
• After completion of the installation Tyvek® FlexWrap has to be covered within 4 months with the appropriate building materials.
