A guide to installing a rainwater outlet.
Place rainwater outlet through the pre-cut hole and mark around it using a crayon or similar.
Prime the underside of the rainwater outlet and 1cm beyond the marked area on the rubber using a quick scrubber pad and handle. Allow both surfaces to dry.
Mate the surfaces together and compress with a silicone roller.
Round the corners of the 18” form flash (outlet kit) with scissors and neatly position over outlet. Mark the perimeter with crayon.
Prime the rubber and outlet using the quick scrubber pad and handle and extend primer beyond the crayon line by 2cm.
Once touch dry, neatly position the 18" form flash and carefully remove the backing paper. Roller firmly in place and use a sharp blade to carefully cut out the hole.
