LEAK STOP

Instructions for use

Before proceeding, please read the following information application carefully to ensure that proper procedures are fully understood. Leak Stop Repair Tape is a specially treated and knitted fibreglass impregnated with a polyurethane resin which is activated by immersion in water. Areas of application: Repairs to leaking pipes.

1. Surface preparation

Remove all pressure from the pipe, including gravity fed drip. For active leaks when pressure cannot be removed: Holes should be stopped using a pipe repair clamp. Remove oil, grease, loose rust scale, sealant tape and paint from repair area. Rough score a four inch (10 cm) path 360° around the pipe centring leak site. Leak Stop works best on a rough surface. If the pipe surface is pitted by rust, remove the loose scale. If the surface is smooth, as with copper or stainless, you must roughen the area with a coarse file, rasp or saw blade. For plastic pipe, the external mould release must be removed.

Rough score surface

Water activate Leak Stop

Abrade surfaces with a coarse grit sandpaper. A saw blade must also be used to create a cross hatch pattern. This is particularly useful on polypropylene and PVDF piping.

2. Mixing

During mixing and application gloves should be worn at all times to protect the hands.

Open pouch at the notch, remove Leak Stop Repair Tape, submerge the roll in water and squeeze two or three times, for about five seconds.
