Whilst it’s primarily used to fix leaky drainpipes and guttering, it can also be an ideal solution for sealing leaky shed roofs, flat roofs, window frames, doors and much more.

Easy to use

The quickest and most convenient way to fix a leak.

Thanks to its spray formulation, Polar LeakFix is easy to use and ideal for application on all indoor and outdoor repair work – without compromising on quality and performance.

Before you start, clean the area and get rid of any loose dirt. It’s also worth removing previous surface coatings with a wire brush or abrasive paper. Apply a minimum of 2-3 coats, leaving 10-15 minutes between applications. Then to ensure maximum paint hardiness, allow 24 hours for it to dry.

Please note – on completion of the job, always invert the can and depress the actuator for a few seconds. This helps to prevent nozzle blockage.
