EFFECTIVE WATERPROOFING FOR SMALL REPAIRS – YKF transparent waterproof sealant 12 oz is a water-based clear coating that cures into a dense protective membrane to help block water, air and moisture. Ideal for small leak repair, surface sealing and waterproof protection around roofs, walls, bathrooms, kitchens, sheds and outdoor areas.
CLEAR FINISH FOR VISIBLE SURFACES – This clear waterproof sealant dries to a transparent protective film, helping protect surfaces without heavily changing their original appearance. Great for visible repair areas such as tile edges, window sills, garden surfaces, patios, planters, birdbaths, sheds and decorative materials where a clear coating is preferred.
SEALS SMALL CRACKS, SEAMS AND GAPS – The liquid waterproof coating spreads into small cracks, seams and surface gaps to create a flexible sealing layer. Helps reduce water seepage around pipes, gutters, skylights, chimneys, shower edges, roof seams and wall joints when the surface is properly cleaned and dried.
MULTI-SURFACE INDOOR AND OUTDOOR USE – YKF invisible waterproof agent can be applied to concrete, wood, brick, metal, ceramic, masonry and other hard surfaces. Suitable for DIY home repair on roofs, exterior walls, basements, bathrooms, kitchens, patios, gardens and window areas. Not recommended for underwater use or high-traffic walking surfaces.
EASY BRUSH-ON APPLICATION AND COVERAGE – Clean and dry the surface before use, then stir well and apply 2-3 even coats with a brush. Each 12 oz container covers up to 15 sq ft depending on surface condition and coating thickness. Allow about 24 hours to cure; drying time may vary by temperature and humidity. Use in a well-ventilated area and apply above 50°F.
