INSTALLING A WALL DRAIN – FLEECE-BACKED

STEP 1

Offer the wall drain into the pre-cut hole in your parapet wall and mark around using a white pencil or scribe

STEP 2

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 it into the sealant.

STEP 3

Fix drain into position using either countersunk screws or clout nails.

STEP 4

Mark 70 mm either side of the drain using a white pencil or scribe.

STEP 5

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.

STEP 6

Prime the drain where the flashing tape is to be applied.

STEP 7

Starting from the bottom fix the base section of flashing first and work into the angle change.

STEP 8

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.

STEP 9

You will now need to seal around this detail using lap edge sealant.
