Kerdi Wall Mat (SQFT)(323 sqft/roll){Roll}

1. The substrate must be clean, even, and load bearing. The adhesive used for bonding Schluter-KERDI must be appropriate for the substrate and must penetrate and engage the KERDI fleece. Generally, a dry-set mortar is used. Cut Schluter-KERDI to size prior to application.
2. Apply the tile adhesive to the substrate using a 1/4" x 3/16" (6 mm x 4 mm) V-notched trowel (Note the open time of the adhesive). Press Schluter-KERDI fully into the adhesive. Work the KERDI into the adhesive by applying pressure to the membrane with the flat side of the trowel (held at an angle) in smooth, diagonal sweeps. Air bubbles must be avoided. An optimal bond is achieved if one side of Schluter-KERDI is first coated with a thin layer of adhesive that engages the fleece webbing.
3. Seams can be constructed by overlapping the edges of the KERDI 2" (5 cm) or by abutting the edges and covering the joint with Schluter-KERDI-BAND, using a dry-set mortar. When anticipating large quantities of water, an impervious adhesive, such as a waterproof mortar, an epoxy mortar, or urethane may be used.
4. For inside and outside corners, adhere the pre-cut KERDI corner sections. For floor/wall connections, use the Schluter-KERDI-BAND. For pipes, use the Schluter-KERDI-KM pipe sleeves.
5. Connections to fixed building elements can be achieved by using Schluter-KERDI, KERDI-BAND, or KERDI-FLEX in conjunction with suitable trowel-applied waterproofing materials, such as those that require atmospheric moisture to cure, or other suitable sealing compounds.
6. Schluter-KERDI shall be separated at existing expansion, structural, or flexible edge joints. Cover the joints with Schluter-KERDI-FLEX. To allow for greater movement, the center section of the Schluter-KERDI-FLEX can be tucked into the cavity of the expansion joint prior to bonding.
7. Once the entire membrane — with seams, corners, and connections — has been completely bonded, and therefore waterproofed, the covering may be applied.
8. For tile installations using the thin-bed method, apply tile adhesive directly to the exposed Schluter-KERDI surface and install the tiles, ensuring full coverage. Use a tile adhesive appropriate for the type of surface covering and intended use. A dry-set mortar is generally used. For acid-resistant coverings, use an epoxy adhesive to set and grout the tile.

Schluter-KERDI is a polyethylene waterproofing membrane with a very high steam-diffusion density. The material is physiologically safe. Schluter-KERDI requires no special disposal.

Schluter-KERDI is waterproof and resistant to most chemicals commonly encountered in tiled environments. It is resistant to aging and will not rot. Schluter-KERDI is highly resistant to saline solutions, acid and alkaline solutions, many organic solvents, alcohols, and oils. Information regarding its resistance to specific substances can be provided if concentration, temperature, and duration of exposure are known. Before placing the Schluter-KERDI, verify that the substrate is even, load bearing, and free from moisture. Surfaces that inhibit proper adhesion must be removed or appropriately treated.

Schluter-KERDI is suitable for wall and floor surfaces where protection against the penetration of moisture or other harmful substances is necessary. Surfaces include tub surrounds, gang showers, and areas surrounding swimming pools. Industrial applications include the food industry, breweries, and dairies.

Schluter-KERDI meets the American National Standard for Load Bearing, Bonded, Waterproof Membranes for Thin-Set Ceramic Tile and Dimension Stone Installations (ANSI A118.10 - 1999)

No maintenance required.
