Closure Cover Sealant System
Processing
The substrate must be free of adhesion-inhibiting components, load-bearing, and even. Any leveling measures should be carried out before installing the closure cover KERDI.
The choice of adhesive for processing the closure cover KERDI depends on the type of substrate. The adhesive must adhere to the substrate and mechanically lock into the fleece of the closure cover KERDI. In most substrates, a hydraulically setting mortar can be used. Compatibility issues between materials should be checked if necessary.
Note: For areas requiring building authority approval, only system-tested hydraulic mortars should be used. These can be obtained at the address specified in this data sheet.
The hydraulic mortar is applied with a notched trowel, recommended 3 x 3 mm or 4 x 4 mm, onto the substrate.
The pre-cut sheets of the closure cover KERDI are fully embedded in the adhesive with the fleece. To embed, the smooth side of the notched trowel or a smoothing trowel is recommended, which is pressed over the KERDI sheet under pressure. Air inclusions should be avoided. The open time of the adhesive must be observed.
KERDI sheets are overlapped by at least 5 cm in the staggered area and bonded with KERDI COLL to the adjacent sheet or butted and fully bonded with KERDI KEBA using the sealing adhesive KERDI COLL.
For interior and exterior corners, pre-fabricated KERDI corners should be used. For corner joints, the closure cover KERDI band should be applied accordingly. For pipe penetrations, KERDI KM pipe collars should be embedded. Connections to fixed installation parts can also be made functionally correctly. Depending on the construction site situation, KERDI, KERDI band, or KERDIFLEX can be used to create a sealed connection with KERDIFIX to the component to be connected.
In the area of hydraulic mortar floor drains, a cut as an access sleeve of the format 50 x 50 cm made of KERDI should be clamped or sealed into the flange of the floor drain. The adjacent KERDI sheet is brought up to the floor drain up to a distance of approximately 10 cm and sealed without voids onto the connection sleeve.
Note on floor drainage systems: KERDI DRAIN and KERDI LINE are specially developed floor drain systems for connection to bonded waterproofing. KERDI can be quickly and securely processed here using the corresponding KERDI sleeves.
Existing movement joints or construction separation joints should be separated from KERDI and overlaid with KERDIFLEX at the staggered connections. For flexible edge terminations, KERDIFLEX should also be used. Alternatively, KERDI band can be used here if a corresponding loop is formed.
Once the entire bonded waterproofing with all overlaps, corners, and connections is sealed, the covering layer can be applied. No waiting time is necessary.
For tile installation, hydraulically setting mortar is applied directly onto KERDI, and the tiles are embedded largely flush with the surface. For chemically resistant coverings, suitable reactive resin adhesives and grouts should be used.
For areas where CE conformity or according to the general building authority test certificate is required, only system-tested hydraulic mortars should be used. The hydraulic mortars and the corresponding test certificates can be obtained at the address specified in this data sheet.
