Schlüter-KERDI is a crack bridging waterproofing membrane made of soft polyethylene, with a special fleece fabric on both sides for effective anchoring in the tile adhesive.
Schlüter-KERDI was developed as a waterproofing membrane for bonded assemblies with floor and wall coverings made of tiles and natural stone.

10m2 Kit Components:

• 1 x Kerdi-200 - Waterproofing Membrane - 10 sq./m roll
• 1 x Kerdi-Coll-L - Sealing Adhesive - 1.85kg
• 2 x Kerdi-Keba - Sealing Band - 5m x 125mm
• 2 x Kerdi-MV - Pipe Collar 135mm - Pipe Diameter 12-30mm 

The waterproofing membrane is adhered to a level substrate with a suitable tile adhesive. The tiles are installed directly over Schlüter-KERDI, using the thin-bed method. Other trowel applied cover materials or plaster can also be installed.

Installation of Schlüter®-KERDI

1. The substrate must be free of bond inhibiting components, be load bearing and even. Any unevenness in the substrate must be levelled prior to the application of Schlüter-KERDI.
2. The type of bonding adhesive used to apply Schlüter-KERDI depends on the type of substrate. The adhesive must bond to the substrate and mechanically anchor the fleece on the underside of the Schlüter-KERDI matting. Verify the compatibility of all materials prior to installation.
   If using covering materials with a lateral length ≥ 30 cm, we recommend a water-binding tile adhesive for rapid curing and drying.
   Note: System tested adhesive must be used in areas that require special approval of the authorities. Please contact us at the address shown in this data sheet for more details.
3. Apply the bonding adhesive to the substrate using a 3 x 3 mm or 4 x 4 mm notched trowel.
4. Individual courses of Schlüter-KERDI are cut to size. Solidly embed the anchoring fleece on the underside in the adhesive so that its entire surface is bonded. Workthe material into the adhesive with the smooth side of a notched trowel or a float, exerting pressure on the Schlüter KERDI matting in diagonal strokes.
   Avoid the formation of air bubbles and observe the open time of the bonding adhesive.
5. Overlap the joints of the KERDI membranes by at least 5 cm or abut the joints and fully cover the joint with Schlüter-KERDI-KEBA, using the sealing adhesive Schlüter-KERDI-COLL-L.
6. Use the pre-fabricated KERDI corners for internal and external corners.
   Schlüter-KERDI-KEBA must be adhered to corner joints in the same manner. Use Schlüter-KERDI-KM (pipe collar) for pipe penetrations. Functional connections to fixed structural components can be created as well. Depending on the situation of the construction site, Schlüter-KERDI,-KERDI-KEBA or -KERDI-FLEX can be attached to the adjoining structural element with Schlüter-KERDI-FIX to create a waterproof connection (see Product Data Sheet 8.3, Schlüter-KERDI-FIX).
   6a. Adhere KERDI-KM or KERDI-MV (pipe collars) around pipe penetrations. As an alternative, our KERDI-PAS sets comprise a plastic sleeve and a KERDI-MV collar. The collar is adhered around the pipe protrusion together with the plastic sleeve to ensure reliable waterproofing of the subsequently installed internally threaded tap extension after removing the plastic sleeve.
7. Clamp or tightly adhere a 50 cm x 50 cm piece of Schlüter-KERDI onto the flange of the floor drains constructed in the thin-bed method as a connector collar. Then bring the Schlüter-KERDI mat within 10 cm of the floor drain and adhere it to the connector collar without leaving air pockets. Schlüter-KERDI-DRAIN is a floor drain specifically designed to allow connections to a bonded waterproofing membrane. This allows the simple and fast connection of Schlüter-KERDI to the floor drain, using the Schlüter-KERDI collar.

KERDI-COLL-L - Sealing Adhesive

How to install this product
Apply the material on clean and dry KERDI, DITRA or DITRA-HEAT membranes/mats, KERDI-BOARD or BARA profiles. The suitability of other substrates must be verified and evaluated. Depending on the application, the material can be applied with the smooth side of a trowel and then grooved with a notched trowel of size 3 x 3, 3 x 4 or 4 x 4 mm. If the material is mixed to a thinner consistency, it can be applied with a brush or a roller.

Fully embed the materials to be adhered as quickly as possible (before a film forms on the surface), avoiding all air pockets.

We recommend drawing the smooth side of the notched trowel over the KERDI-KEBA tape or using a suitable pressure roller for adhering the seaming tape. Again, make sure there are no air bubbles.

KERDI-KEBA - Sealing Band

Whether you opt for DITRA mats or KERDI waterproofing membrane, the abutting joints between elements as well as wall/floor transitions require reliable waterproofing. We have two products in our range for this: KERDI-KEBA polyethylene sealing band with fleece laminated on both sides and the KERDI-COLL-L sealant adhesive. 

• Width - 12.5cm
• Thickness - 0.1mm
• Material - PE (polyethylene)
• Install using the sealing adhesive Schlüter-KERDI-COLL-L

Schluter KERDI-MV - Waterproofing Collar - 12-30 mm Pipe Diameter

The prefabricated waterproofing collars KERDI-MV offer reliable waterproofing of pipe penetrations in accordance with DIN 18534 for wet rooms. For added practicality, KERDI-MV comes in different sizes so you can select the collar that suits your pipe diameter:

• Collar Diameter - 135mm
• Pipe Diameter - 12-30 mm (KMV9)
• Thickness - 0.1mm
• Material - PUR (polyurethane)
• Install using the sealing adhesive Schlüter-KERDI-COLL-L
• For use with KERDI 200 Waterproof membrane
