ELASTICITY & EXTENSIBILITY: Waterproof coating sealant can smoothly cover small gaps and cracks, effectively resisting deformation of the substrate. Rubber sealant initial film formation occurs in 2-4 hours, forming a flexible rubber coating that provides lasting waterproof protection.
LONG-LASTING WEATHER RESISTANCE: Professional rubber sealant waterproof membrane remains stable in high and low temperatures (-40 °C to 80 °C/-40 °F to 176 °F). Waterproof coating has good adhesion on multiple surfaces, not easy to crack and effectively resists aging.
ROOF SEALANT WATERPROOF LEAK REPAIR: 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. Not suitable for walking surfaces due to tackiness when cured.
MAXIMUM COVERAGE AREA AND PERFORMANCE: Concrete
foundation vertical surfaces: 0.6 mm thickness covers 2 m² ( 21.4 ft²); flat/low-slope roofs and standing water surfaces: 1 mm thickness covers 1 m² ( 10.7 ft²). Use polyester fabric at joints and obvious cracks to enhance waterproofing performance.
FLEXIBLE WATERPROOF SEALANT: Foundation sealant waterproof has self-leveling properties and can be applied with a brush, roller, scraper, or poured. It cures quickly to form a dense rubber waterproof membrane, effectively sealing water, gases, and moisture indoors and outdoors to prevent leaks
