Product Description:

Kiesel Okamul DF is a premium liquid waterproofing membrane engineered to deliver reliable protection and performance for interior tile installations in wet and high-moisture environments. This flexible polymer-based system is solvent-free and designed to create a seamless, elastic waterproof layer that protects substrates from water penetration while maintaining structural durability. Once cured, it forms a continuous membrane that resists cracking and prevents water infiltration, making it an essential component for long-lasting tile installations.

Designed for versatility, Okamul DF can be applied to a wide range of substrates including gypsum boards, plaster, concrete, cement screeds, and autoclaved aerated concrete. Its excellent adhesion properties allow it to bond directly to surfaces without the need for complex preparation, simplifying installation for both professionals and DIY users. The liquid consistency ensures even coverage and eliminates seams, reducing the risk of weak points and improving overall waterproofing performance.

This membrane system is particularly effective in areas exposed to frequent moisture such as bathrooms, showers, kitchens, and laundry rooms. It performs equally well in residential and commercial settings, including public shower facilities with floor drains or private bathrooms without drainage systems. Its ability to bridge cracks up to 3 mm ensures that minor substrate movement does not compromise the integrity of the tiled surface.

Installation is straightforward and efficient, with a fast drying time of approximately 1 to 2 hours depending on conditions. The product can be applied using standard tools and integrates seamlessly with thinset mortar systems for tile installation. Its coverage of approximately 84 to 94 square feet per container makes it a practical and cost-effective solution for a wide variety of project sizes.

Whether you are undertaking a full bathroom renovation, upgrading a shower system, or completing a new construction project, Kiesel Okamul DF provides a dependable waterproofing solution that enhances durability and protects your investment. Its combination of flexibility, strength, and ease of use makes it a trusted choice for achieving professional-grade results in any interior waterproofing application.
