Schluter-Systems offers a variety of systems for tile installation,
including uncoupling and waterproofing membranes, shower systems, and building panels.
Schluter thin-set mortars are specifically formulated for use with these systems
to help ensure successful tile installations in a wide range of applications.
Now, we’ll demonstrate using our thin-set to install the DITRA uncoupling
membrane family of products. For all Schluter® thin-set mortars
the procedures for installation are the same: Before application of the mortar to the substrate,
make sure that the substrate is clean, even, and load bearing.
Sweep the floor to remove any debris and clean any dust from the substrate with a damp sponge.
For particularly dry and porous substrates it is recommended to wet the substrate first,
in order to help prevent premature drying or skinning of the thin-set mortar.
Apply a thin layer of the mortar with the flat side of the trowel to produce
solid contact with the substrate. Comb additional mortar using the notched
side of the appropriate sized trowel. Mortar ridges should run in one direction.
Solidly embed the membranes into the mortar using a float.
Proper installation results in full contact between the fleece webbing and the mortar.
Check coverage and re-embed the membrane. Observe the open time of the mortar.
Open time refers to how long the mortar can remain exposed once it is has been
spread onto the substrate before skinning over. If the mortar skins over, remove
and reapply before installing the membrane. For SET and ALL-SET the open time is 20 minutes.
For FAST-SET the open time is 10 minutes. Now, we’ll demonstrate using our thin-set
to install the KERDI waterproofing membrane family of products.
Prepare the substrate in the same way as demonstrated earlier in this video.
Apply a thin layer of the mortar with the flat side of the trowel
to produce solid contact with the substrate. Then comb additional mortar using the notched side.
Solidly embed the membrane into the mortar using the flat side of the trowel
or a drywall finishing knife to ensure full coverage and to remove air pockets.
Check for coverage and re-embed the membrane.
Finally, let’s demonstrate tile installation over our membranes using Schluter thin-set
mortar. We’ll continue working with the KERDI family in this example.
Select a notched trowel that is suitable for the tile format.
Burn a thin layer of mortar on the surface of the membrane or board
using the flat side of the trowel. Comb additional mortar using the notched
side of the trowel, making sure the mortar ridges run in one direction.
Solidly embed the tile in the mortar, pushing the tile in a back and forth
motion across the mortar ridges. When tiling, periodically remove and
check the tile to ensure sufficient coverage. Take care not to pull up on the membrane below.
Clean all excess mortar from tile, joints and tools while it is still
wet using a sponge and clean water. When using SET and ALL-SET, wait twelve hours
before grouting at standard temperature. FAST-SET allows you to grout after four hours.
Always remember to protect the installation from heavy traffic
for a minimum of twenty-four hours. Schluter thin-set mortars are the ideal
choice when working with Schluter systems. Our setting materials are
engineered to deliver premium performance in conjunction with our membranes and boards.
Schluter thin-set mortars… Now—you’re all set!
