300g Transparent Waterproof Crack & Leak Sealant

Reliable transparent waterproof protection for walls and floors

This 300g transparent waterproof adhesive coating is engineered to seal leaks, hairline cracks and joints on exterior walls and wet-area floors. The water-based, solvent-free formula forms a continuous, elastic film that blocks water penetration while remaining clear, so existing finishes and colors stay visible.

Designed for use on concrete, tile, stone and similar mineral surfaces, it creates a moisture-resistant barrier that helps prevent seepage, peeling paint, efflorescence and surface deterioration. Its mold-resistant properties inhibit the growth of mold and mildew in high-humidity areas such as bathrooms, balconies, kitchens and utility rooms, supporting a cleaner and more hygienic environment over time.

Why It's a Smart Choice

• Long-lasting waterproof film - Forms a durable, continuous coating that resists water infiltration on exterior walls, floors and joints, reducing the risk of recurring leaks.
• Transparent, neat finish - Dries clear without tint or streaks, so it does not alter the appearance of tiles, stone or painted surfaces and can be overcoated if desired.
• Stable in heat and cold - Formulation is designed to resist sagging in hot weather and reduce cracking or flaking in colder conditions, for consistent performance across seasons.
• Low-odor and surface-safe - Water-based, non-solvent formula with low odor, developed to minimize impact on indoor air and avoid corrosion or damage to compatible substrates.
• Simple application - Clean and dry the area, spread an even layer over cracks or joints, then allow 24-48 hours for full film formation and waterproofing.
