HOW TO INSTALL RETROSEAL SUPERSEAL IN YOUR SHED

Fitting the Backbone 

Squash the lower fin of the flashing between the overhanging wall sheet and the edge of the concrete slab, with the fingerlip touching the floor, and the serrated rail to the top. 

If the wall sheet is hard against the concrete, it may be necessary to loosen screws on the bottom girt. However, the flashing can usually be forced in. In this situation, it can be held in position with a few dobs of silicon under the fingerlip as an extra securement. 

If a gap exists between the wall sheet and the concrete slab, the flashing should be fixed at its vertical face to the sheet pan area by a 10/16 tek screw or equivalent. The fingerlip can cover up to 27mm of gap. 

One of the best ways to do this is to drill a hole from the inside out with a smaller bit than the screw being used (while maintaining a position to effect the neatest finish), with a second person screwing a tek back from the outside, using the hole as a pilot (careful not to overscrew). The ideal screw position is beside the sheet profiles. Use enough screws to achieve the desired finish. Pop rivets can also been used successfully. 

Fitting the Tabs 

Position a tab on the serrated rail. Apply pressure with the thumb on the tab curve and the extraction fin, and snap it in to the first groove. If a gap still exists between the tab and the wall profile, apply more pressure to snap it into the second groove and so on. 

If it goes too far, use a screwdriver under the extraction fin to recover it and start again. On bigger tabs, it may be necessary to use a blunt screwdriver under the extraction fin, resting lightly on the tab curve, and tap with a hammer. 

NOTE: Superseal should be stored in a cool place and out of direct sunlight prior to installation.
