Step 1

Place the outlet through the wall and mark around it using a crayon or similar, allowing an additional 1cm around the perimeter.

Step 2

Stir thoroughly and prime the underside of the outlet and the marked area on the rubber using a quick scrubber pad and handle. Allow both surfaces to dry.

Step 3

Mate the outlet to the rubber and seal in place using a penny and silicone roller.

Step 4

Round the corners of the 18" SA flashing (outlet kit) with scissors and neatly position over outlet. Mark the perimeter with crayon.

Step 5

Prime the rubber and outlet using the QuickScrubber pad and handle and extend primer beyond the crayon line by 2cm and into the mouth of the outlet by 100mm.

Step 6

Once touch dry, working from the bottom, position the 18" SA flashing and carefully remove the backing paper. Ensure it is tightly sealed into the corners and use a penny and silicone roller. Carefully cut the sides and top at the aperture and allow the flap to drop into the primed outlet.
