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.
