INSTALLING A WALL DRAINAdam Kent
Offer the wall drain into the pre-cut hole in your parapet wall and mark around using a white pencil or scribe
Remove the wall drain and apply a thin bead of lap edge sealant behind the drain.
Once the sealant is fully applied push the drain back into position to bed into the sealant
Measure between the outer lines using a tape measure to determine the length of the flashing tape. Using the newly determined measurements, cut 2 pieces of 225 mm flashing tape to length.
Starting from the bottom fix the base section of flashing first and work into the angle change.
Fix the top section of the tape working from top to bottom overlapping the bottom section of tape.
Once the tape is fixed in place pressure must be applied with a seam roller to ensure correct adhesion.
All FlexiProof tapes are pressure sensitive and always require rolling.
