The DemoFlex™ TMS Underlayment Kit consists of DemoFlex Membrane Underlayment in either: 40"x90' (300SF), 20"x90' (150SF) and 12"x100' (100SF) rolls, along with the corresponding DemoFlex Adhesive Spray Can and Seam Tape included. This original membrane version utilizes our Double Reinforced Fibrous Membrane technology for excellent moisture resistance, outstanding bond strength with less than 1mm of thickness.
DemoFlex Sound has achieved an IIC rating of 63 and STC rating of 64 for sound deadening to be used in ceramic tile floor installations with an IIC Delta of 17.Heavy TrafficClassifications in ASTM C627 Robinson testing proves its suitability for commercial & residential use. The ANSI A18.104.22.168 standards for High Performance Crack-Isolation Classifications add value to the life of the floor along with the membranes passing ANSI 22.214.171.124 Hydrostatic Pressure testing by the TCNA. DemoFlex Sound Underlayment requires the use of DemoFlex Adhesive which can besold separately.
From a standing position, spray the DemoFlex Adhesive onto the existing substrate/concrete, wait 20-40 minutes for the adhesive to activate, thoroughly press the DemoFlex into the DemoFlex Adhesive then it is immediately ready to set the Mortar, Tile and Grout directly on top of our membrane following industry standards. It is recommended to treat the seams & perimeter with DemoFlex Tape (included) or with a high quality silicone caulk.
This inexpensive system meets Extra Heavy Traffic Classifications in ASTM C627 Robinson testing therefore suitable for commercial and residential use. DemoFlex also exceeds the ANSI A126.96.36.199 standards for High Performance Crack-Isolation Classifications, both completed by Tile Council of North America.
By encapsulating the mortar along with allowing the tiles to be removed in full pieces with no grinding mortar; the exposure is likely below the Permissible Exposure Limit (PEL) 25 µg/m3 standard set by OSHA-1926.1153 eliminating the need for extra procedures. This will help reduce the need for having regulated work-zones because the exposure is so low and won't likely even reach the OSHA standards.(click here for more information on the new Silica Standards)
