At the joints, fill the cut-back cavities with Schluter
SET™, Schluter ALL-SET™, Schluter FAST-SET™,
or unmodified thin-set mortar, approximately 8" (203
mm) wide, centered over the joint.
Comb additional Schluter SET™, Schluter ALL-SET™, Schluter FAST-SET™, or unmodified thin-set
mortar over the joint using a 1/4" x 3/16" (6 mm x 5 mm) V-notched trowel or the Schluter

trowel, which features a 1/8" x 1/8" (3 mm x 3 mm) square-notched design. Using the flat side of the
trowel, firmly press the 5" (127 mm)-wide Schluter

-KERDI-BAND into the mortar to ensure 100%
coverage and to remove excess mortar and air pockets.
At all wall junctions, apply KERDI-BAND as described
in steps 1-3, ensuring a minimum of 2" overlap on
to DITRA/DITRA-XL.
Notes
KERDI-BAND must lap DITRA and DITRA-XL at seams and at floor/wall transitions by a minimum of
2" (50 mm) in order to maintain waterproof integrity.
In some applications the vertical section of the floor/wall transition will not accept a bond to
unmodified thin-set mortar. Connections to such elements can be achieved using Schluter
