Product Details

Seal leaks fast with Polar LeakFix Liquid Rubber, a rubberised roof sealant that forms a strong, flexible membrane over leaks, cracks and damaged exterior surfaces. It moves with the roof beneath it, helping protect against damp and weather damage.

Use it for emergency repairs or as part of regular roof maintenance. No primer is needed and one generous coat is normally enough.

Key Features

Waterproofs Instantly: Seals leaks and cracks as soon as it goes on.

Flexible Rubber Membrane: Stays flexible, so the seal moves with the surface beneath.

One Coat: One generous coat is normally enough. Porous or difficult surfaces may need a second coat after 2-3 days.

No Primer Needed: Apply straight from the tin with a brush or roller once the surface is clear of debris and standing water.

Coverage: Approximately 1m² per litre, depending on the surface and how it is applied.

Drying Time: Touch dry in 3-4 hours and fully cured in 6-7 days.

Where To Use It

Flat and pitched roofs, felt roofs, sheds, gutters, windows, pipework and drainpipes. Suitable for asphalt, bitumen, brick, concrete, stone, tiles, grout, fibreglass, wood, metal and lead.

Available in Clear and Grey.
