Blanke Securmat is a tear-proof uncoupling tile underlayment membrane that provides a secure bonding surface for ceramic tile and natural stone installations.  Blanke Securmat can be used on both interior floors and walls.  Securmat also provides superior crack isolation protection.  If the substrate may be subject to lateral movement of any kind, the crack isolation properties will help protect and prevent damage to the tile covering.  This product is extremely light weight, thin, and easy to install.  Because it features such a thin, low elevation, it requires much less thinset mortar than most other rolled uncoupling products.  Blanke Securmat is perfect for new installations as well as for remodels and renovations over existing floor coverings.



  • Low elevation
  • Easy to cut and install
  • Uses less thinset than other uncoupling products
  • Provides uncoupling crack isolation properties
  • Approved for wood and cement substrates
  • Approved for use with modified thinset mortar
  • Approved for all tile sizes including mosaics


1.  Prep and clean the substrate
2.  Mix modified thinset mortar
3.  Apply thinset to the substrate using a 1/4" x 5/16" V-notched trowel
4.  Cut the Securmat to fit the area to be tiled - Adjacent sections should be butted at the edges without overlapping
5.  Use the flat side of the trowel to press the Securmat into the thinset eliminating any air pockets
6.  Allow thinset to cure
7.  Apply another layer of thinset on top of the Securmat using a trowel appropriate for the size and type of tile
8.  Set the tile


Blanke Securmat has successfully completed rigorous testing by the TCNA (Tile Council of North America, Inc).  Securmat installation completed thirteen cycles with no evidence of damage to the tiles or grout joints.  At the completion of cycle fourteen (steel wheels, 300 pounds per wheel), there was one spalled grout joint.  All evaluation criteria were based on 8 tiles and 8 grout joints in the wheel path of the Robinson-Type Floor Tester.

The installation was classified as "Extra Heavy" for "extra heavy and high-impact use in food plants, dairies, breweries, and kitchens".
