Storage and handling
Store in warm, dry and clean environment in its current packaging. The tape should not be exposed to long periods of ultraviolet
light. In very cold weather, prior to use ensure that the material is stored in warm conditions above 5°C.
Preparation
Ensure all surfaces are clean and dry. The membrane joint surfaces should be dry and free from contamination such as dust or
sand. Ensure the surface and working area is not water logged. Avoid areas of unsupported jointing.
Installation
The membrane should be overlapped by at least 150mm, bonded with Visqueen Pro Double Sided Jointing Tape and sealed with

When using the GR Foil Lap tape, apply the tape equidistant over the lap area of the laid sheet and the overlap adjoining
membrane. Apply pressure to the jointed area to ensure adhesion. Once the tape is applied, the completed lap should be well
rolled with frm pressure to ensure a complete seal joint has occurred, and continuity with the adjacent sheet has been achieved.
