Any leveling of the floor must be done

prior to the installation of the shower tray.

If necessary, cut the tray to size prior to

application. The shower base can also be

extended beyond the tray using dry-pack

mortar, which is in turn covered with the

KERDI membrane.

Cut the flat end of the KERDI-SHOWER-LT/-LTS tray to fit around the channel support. Apply

Schluter SET

, FAST-SET

, or unmodified thin-set mortar to the substrate using a 1/4"

x 3/8" (6 mm x 10 mm) square- or U-notched trowel. Slide the KERDI-SHOWER-LT/-LTS under

the edge of the channel body flush with the surface of the channel support, making certain to

solidly embed the tray in the mortar. Check the underside of the tray to ensure that full coverage

is achieved. Note: The thin-set mortar used in this step is to bed and support the tray only.

Place a mortar screed opposite the installed

KERDI-LINE channel body.

Fill the remainder of the shower base with

mortar and slope the mortar bed at 1/4"

(6 mm) per 12" (305 mm) using the bonding

flange and a perimeter screed as guides.

Note: When KERDI-LINE is placed at an intermediate location (e.g., center of a shower), it is recommended that the KERDI-SHOWER-LT trays be cut

by equal amounts from the ends to ensure a consistent height of the first course of tile. When KERDI-LINE is placed adjacent to the wall, cut the KERDI-

SHOWER-LTS trays from the thicker end to ensure a flush transition at the drain.

As soon as the mortar bed can be

walked upon, waterproofing with the

KERDI membrane can begin.

Press the bench firmly into place and check

the underside and backsides to ensure that

full coverage and support are achieved.

Verify that the slope on the surface of the

bench is directed toward the shower base.

Install KERDI-BAND and KERDI-KERECK

and KERDI-KERS-B (for triangular bench)

to cover all seams and corners, ensuring a

minimum 2" (50 mm) overlap, and work the

membrane into the mortar to achieve full

coverage and remove air pockets.
