Uncoupling Membrane Mortar is a dry-set mortar for use in large-and-heavy-tile and thin-set applications for installing tile on floors and walls. Technical Data Sheet EN-US
Does uncoupling membrane mortar contain polymer?
MAPEI's Uncoupling Membrane Mortar does not contain polymer and is considered non-modified. If you add a liquid latex additive such as MAPEI's Polymer Additive to a non-modified mortar, it becomes modified. What is the proper way to mix a cement-based mortar? Be sure to follow the packaging instructions carefully when mixing.
What is a uncoupling membrane and how does it work?
Uncoupling membranes are primarily designed for use over concrete slabs and subfloors, especially ones with defects, such as depressions or high moisture levels. In addition, they provide a stable substrate for tile installation on oily asphalt or extremely smooth surfaces for which adhesion is a problem.
Can you use uncoupling membrane under floor tile?
Uncoupling membrane is a waterproof material used under floor tile. If you're going to install floor tile, you need some kind of underlayment, like cementboard (tile backerboard) or an uncoupling membrane. Plywood isn't suitable because it's too flexible, and it isn't waterproof.
Can you use uncoupling membranes on plywood?
Although some substrates absolutely require uncoupling membranes, they can be installed on a range of surfaces, including cement mortar, backerboard, OSB, and plywood. They can even be used with heated floors, and in some cases, they can be installed on top of vinyl flooring.
When would you use an uncoupling membrane?
Most commonly, uncoupling membranes are used when laying tile over concrete. Concrete contains a relatively large amount of water and will shrink and expand due to humidity and temperature changes.
Can I use uncoupling mortar for tile?
As with all non-modified ANSI A118. 1 thin-set mortars, Custom Building Products' Uncoupling Mat Mortar should not be used alone to CUSTOM's Uncoupling Mat Mortar for the installation of ceramic tile and stone when using an uncoupling membrane. install the uncoupling membranes directly to plywood or OSB subfloors.
Is uncoupling mortar the same as unmodified?
Uncoupling Membrane Mortar is an unmodified, dry set, medium bed mortar that was created for use with uncoupling membrane and waterproofing membrane.
Do I need uncoupling membrane on concrete?
Uncoupling membranes are invaluable if you anticipate any movement or cracking from the concrete floor. Generally, it is well worth the cost and the time to purchase and install an uncoupling membrane. Uncoupling membranes are not perfect, though.Mar 25, 2022
How long does uncoupling mortar take to dry?
Protect installation from traffic and wait to grout for 24 to 48 hours. Protect from heavy traffic for 7 days. Protect from rain or frost for 7 days. Large-format tile and low-absorption tile may require a longer time to fully set before tiles can be grouted.
Can I use uncoupling membrane mortar with DITRA?
In general, we don't recommend the use of modified thin-set mortar to set tile over the membranes because these mortars must air dry to cure properly. When sandwiched between two impervious layers such as DITRA and porcelain tile, drying takes place very slowly through the open grout joints.
Is uncoupling membrane mortar modified?
MAPEI's Uncoupling Membrane Mortar does not contain polymer and is considered non-modified. If you add a liquid latex additive such as MAPEI's Polymer Additive to a non-modified mortar, it becomes modified.
Is Mapei uncoupling membrane mortar unmodified?
Uncoupling Mat Mortar: This is Custom's premium unmodified mortar made specifically for Custom's spiderweb mat and other ditra-like products. It is difficult to find and has limited availability.
Should I use modified or unmodified thinset?
Modified thinset is the product of choice for most tile installations because of its increased strength and bonding with minimal shrinkage, which means a reduced chance of cracks forming in the tile. WarmlyYours Radiant Heating recommends modified thinset mortar for nearly all tile and stone installations.Feb 22, 2019
Are uncoupling membranes waterproof?
Tile installers usually use cementboard as a tile underlayment over a standard plywood subfloor, but as Home Flooring Pros advises, there are situations for which an uncoupling membrane is a better choice. It's completely waterproof, and it allows the subfloor and tile layer to move independently.
Can you use uncoupling membrane outside?
This expansion joint is filled with a flexible sealant that allows for movement. On top of the cement slab, an uncoupling membrane that's approved for use outdoors ensures that any cracking won't transfer to the tile. A couple of examples of uncoupling membranes include Laticrete Stratamat and Schluter Ditra mat.Jul 15, 2019

What is an uncoupling membrane?
Uncoupling membrane is a waterproof material used under floor tile. Image Credit: Stephen Paul for Hunker. If you're going to install floor tile, you need some kind of underlayment, like cementboard (tile backerboard) or an uncoupling membrane. Plywood isn't suitable because it's too flexible, and it isn't waterproof.
What is the best way to fix high spots on concrete?
You should also clean the concrete with a solution of trisodium phosphate (TSP) and water, which removes oils and etches the surface, improving mortar adhesion.
Can cementboard be used as a tile underlayment?
Tile installers usually use cementboard as a tile underlayment over a standard plywood subfloor, but as Home Flooring Pros advises, there are situations for which an uncoupling membrane is a better choice. It's completely waterproof, and it allows the subfloor and tile layer to move independently.
Can you use an uncoupling membrane on a wood floor?
One advantage of uncoupling membrane in this situation is that it doesn't raise the height of the floor as much as cementboard.
