YKF 34oz Clear Waterproof Sealant – Invisible Water-Based Leak Repair for Roofs, Walls, Bathrooms

Clear, Invisible Waterproofing for Every Surface

YKF 34oz Clear Waterproof Sealant is a water-based solution designed to protect roofs, walls, bathrooms, kitchens, gardens, and both indoor and outdoor spaces. It forms a dense, flexible membrane that blocks air, water, and moisture, helping surfaces stay dry while preserving the natural look of the substrate. This option suits both DIY projects and professional workflows, offering a reliable, unobtrusive repair that blends with the surrounding texture.

Discreet Finish That Looks Like It Was Always There

One standout quality is its invisible finish. When fully cured, the sealant dries completely clear, so repairs near windows, fascia boards, tile backsplashes, or shower surrounds remain visually seamless. This makes it easier to maintain design continuity on façades, bathrooms, kitchens, and interior walls.

Durable, Weather-Ready Performance

Designed for real-world conditions, the formula features UV resistance and flexible polymers that tolerate temperature fluctuations. The result is a durable coating that helps prevent cracking and drying out in sun, rain, or frost, providing year-round protection without becoming brittle.

Versatile, Easy Application on Multiple Materials

Apply with a brush on concrete, wood, metal, or tile for a wide range of sealing needs. The product is well suited for kitchens, gardens, gutters, and hard-to-reach corners, offering a straightforward solution that saves time and effort while delivering a clean, professional look.

Coverage, Curing, and Practicality

Each 34oz container covers up to 15 sq ft with 2-3 coats and cures to a strong, flexible film in about 24 hours under proper conditions. Pro tips include working above 5°C (41°F), thawing fully if frozen in transit, and checking local weather before winter orders to plan your projects.
