Schlüter Kerdi-Coll-L Dichtkleber 2K

Closure Cover KerdiCollL Sealant 2K

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 with 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. For most substrates, a hydraulically setting mortar can be used. Compatibility of materials should be checked if necessary.

Note: For areas requiring building authority approval, only system-tested hydraulic mortars should be used. These can be inquired about at the address provided 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 applied adhesive with the fleece. To embed, the smooth side of the notched trowel or a smoothing trowel pressed over the KERDI sheet is recommended. 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 the closure cover KERDI COLL to be fully bonded or butted and bonded with the closure cover 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 bonded accordingly. For pipe penetrations, install closure cover KERDI KM pipe sleeves. Connections to fixed components can also be made functionally correctly. Depending on the construction site situation, closure cover KERDI, KERDI band, or KERDIFLEX can be used to create a tight connection with the component to be connected, fixing it with the closure cover KERDI FIX.

In the area of hydraulic mortar floor drains, a cutout in the format 50 x 50 cm of closure cover KERDI can be clamped into the flange of the floor drain or sealed with it. The adjacent KERDI sheet is brought up to the floor drain with a distance of about 10 cm and sealed without voids on the connection flange.

Note on floor drains: Special floor drain connections have been developed for connection to bonded waterproofing using closure cover KERDI DRAIN and KERDI LINE. KERDI can be quickly and securely processed here using the corresponding KERDI sleeves.

Existing movement joints or construction separation joints should be separated with closure cover KERDI and overlapped with KERDIFLEX at the staggered connections. For flexible edge terminations, use KERDIFLEX or alternatively KERDI band if a loop is formed.

Once the entire bonded waterproofing, including 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 it. For chemically resistant coverings, suitable reactive resin adhesives and joint mortars 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 inquired about at the address provided in this data sheet.
