ARDEX S 1-K One-Gallon Waterproofing and Crack Isolation Membrane presents a revolutionary solution for ensuring the longevity and integrity of interior tiling projects. This innovative, single-component formula is designed to create a robust, flexible waterproof coating, making it an essential component for any project in moisture-prone areas like bathrooms and showers. Not only does it provide superior waterproofing capabilities, but it also excels in crack isolation, effectively managing up to 1/8 inch (3 mm) cracks. This feature is particularly important in safeguarding the structural integrity of your tile installations against potential damage. The convenience of its one-gallon size and the ease of application, whether using a paint roller or brush, makes ARDEX S 1-K a preferred choice among professionals. Its ability to bond with a broad range of substrates adds to its versatility, while the flexibility and durability of the coating ensure that your tile installations remain protected and visually appealing for years to come.
