Ardex SK Mesh – Non-Woven Polyester Reinforcement Fabric Roll for Waterproofing Membranes and Crack Isolation

Product Features:

• Alkali-Resistant Fiberglass Mesh – Designed to resist deterioration from cement-based compounds and maintain integrity over time.
• Enhances Crack Isolation Performance – Reinforces waterproofing membranes to reduce substrate movement transmission and prevent tile cracking.
• Ideal for Wet Areas – Suitable for showers, tubs, kitchens, laundry rooms, balconies, terraces, steam rooms, and more.
• Easy to Embed – Mesh integrates smoothly into wet waterproofing membranes for a strong bond without wrinkles or bubbles.
• Perfect for Corners and Transitions – Use in areas prone to stress, such as wall-to-floor junctions, changes in plane, or substrate joints.
• Supports Tile Installation Systems – Works under ceramic, porcelain, glass tile, natural stone, and large format tiles for added reinforcement.
• Compatible with ARDEX Membranes – Optimized for use with ARDEX 8+9, S 1-K, S 2-K, and other ARDEX tile and stone installation systems.
• Roll Format for Convenience – Available in easy-to-cut roll format for flexible coverage in small or large waterproofing projects.
• Commercial and Residential Use – Ideal for both professional contractors and DIY installers working on new builds or renovations.
• Meets Industry Standards – Supports systems compliant with ANSI A118.10 (waterproofing) and A118.12 (crack isolation).

Product Description:

ARDEX SK Mesh is a premium-grade reinforcement fabric specifically engineered to improve the strength, flexibility, and long-term performance of waterproofing and crack isolation systems in tile and stone installations. Crafted from high-quality, alkali-resistant fiberglass, this mesh roll is designed for superior durability in demanding environments, providing exceptional resistance to degradation when embedded in cement-based or polymer-modified compounds.

ARDEX SK Mesh is purpose-built for use with ARDEX waterproofing and crack isolation membranes such as ARDEX 8+9, ARDEX S 1-K, and other compatible liquid-applied or sheet-applied systems, making it an essential accessory for both professional contractors and serious DIY installers seeking a watertight, crack-resistant substrate.

Perfect for bathrooms, showers, steam rooms, kitchens, laundry areas, balconies, terraces, and exterior tiled applications, ARDEX SK Mesh reinforces weak points in a substrate, preventing movement-related cracking and extending the service life of tiled surfaces. It delivers excellent dimensional stability over a variety of surfaces, including concrete, cement backer board, gypsum wallboard, fiber-cement board, and exterior-grade plywood. By adding structural integrity to areas most susceptible to stress—such as inside and outside corners, changes in plane, seams, control joints, wall-to-floor junctions, and substrate transitions—this mesh helps ensure a continuous and uninterrupted waterproofing layer.

The fine fiberglass weave of ARDEX SK Mesh is lightweight yet strong, allowing it to embed easily into wet waterproofing membranes without adding unnecessary bulk. This creates a seamless, reinforced barrier that bonds securely with the underlying substrate while maintaining flexibility to accommodate minor structural movement. The open-weave design promotes optimal adhesion and ensures the membrane fully encapsulates the fibers, enhancing both tensile strength and crack-bridging capabilities.
Whether you are installing ceramic tile, porcelain tile, glass mosaics, or natural stone, ARDEX SK Mesh provides the reinforcement necessary to prevent premature membrane failure and protect your investment. It is suitable for both commercial and residential waterproofing projects, meeting industry standards ANSI A118.10 for waterproofing and ANSI A118.12 for crack isolation. For new construction, remodels, or repairs, ARDEX SK Mesh offers unmatched reliability, helping create a stable, waterproof foundation for tile installations that will perform beautifully for years to come.
