Rubber Liquid Waterproof Sealant, 53oz/1.5kg Black Quick Drying Multi Surface Foundation Leak Repair - Roof Gutters Basement Sealer Waterproof - Indoor & Outdoor Flexible Rubber Paint

ELASTICITY & EXTENSIBILITY: The waterproof coating sealant smoothly covers small gaps and cracks while effectively resisting substrate deformation. The initial film forms in 2-4 hours, creating a flexible rubber coating that offers lasting waterproof protection.
LONG-LASTING WEATHER RESISTANCE: The professional rubber sealant waterproof membrane remains stable in high and low temperatures from -40 °C to 80 °C (-40 °F to 176 °F). The waterproof coating provides good adhesion on multiple surfaces, resists cracking, and effectively resists aging.
ROOF SEALANT WATERPROOF LEAK REPAIR: The waterproof sealant is suitable for metal roofs, sheds, concrete basements, walls, gutters, wooden skylights, flower pots, low-pressure small swimming pools, bird baths, and fountains. It is not suitable for walking surfaces because it remains tacky when cured.
MAXIMUM COVERAGE AREA AND PERFORMANCE: On vertical concrete foundation surfaces, a 0.6 mm thickness covers 2 m² ( 21.4 ft²). On flat or low-slope roofs and standing water surfaces, a 1 mm thickness covers 1 m² ( 10.7 ft²). Use polyester fabric at joints and obvious cracks to enhance waterproofing performance.
FLEXIBLE WATERPROOF SEALANT: The waterproof foundation sealant has self-leveling properties and can be applied with a brush, roller, scraper, or by pouring. It cures quickly to form a dense rubber waterproof membrane that effectively seals water, gases, and moisture indoors and outdoors to prevent leaks
