JENOLITE Stop Leak Sealer Spray CLEAR 3 x 400ml for Gutters and Flat Roofs Waterproof Gutter Sealant Fills, Seals & Stops Leaks Long Lasting

WATERPROOF STOP LEAK SEALER: JENOLITE Stop Leak Sealer Spray is a White waterproof sealing compound supplied in a 400ml aerosol format, designed to fill, seal, and reinforce areas affected by leaks. The spray-on formulation allows the liquid sealant to penetrate fine gaps, cracks, and joints before forming a continuous sealing layer. Suitable for use on metal, plastic, wood, masonry, and other common surfaces, providing practical leak control for maintenance and repair tasks while remaining visually discreet after application. VERSATILE LEAK REPAIR APPLICATIONS: This stop leak spray is suitable for addressing leaks on roofs, gutters, pipes, downpipes, joints, seams, vents, and fittings. Designed for domestic, automotive, marine, and general maintenance use, the spray format supports even coverage on irregular shapes and hard-to-reach areas. Ideal for preventative maintenance and minor repairs where a flexible sealing layer helps reduce water ingress across commonly exposed surfaces. EASY SPRAY APPLICATION & COVERAGE: Shake the can thoroughly before use and apply directly to a clean, dry surface using steady, overlapping passes. Multiple thin layers are recommended to build coverage, allowing drying time between coats. Once cured, the sealant forms a continuous coating designed to remain intact during regular use. The 400ml aerosol size supports controlled application for small to medium repair tasks without additional tools. SAFE & CONTROLLED FORMULA: Apply in a well-ventilated area and wear suitable gloves and eye protection during use. Avoid inhalation of spray mist and direct contact with skin, eyes, or clothing. Keep away from open flames, sparks, and heat sources. Store the can upright in a cool, dry place and do not expose to temperatures above 50°C. Do not puncture or incinerate the container, even when empty.
