PRODUCT DESCRIPTION Whisper Mat CS is a peel-and-stick Membrane that reduces impact and airborne Sound transmissions and isolates finished flooring from the transfer of subfloor cracks. Accessory Materials No. 6000 Primer - This high tack water based primer is ideal for use on indoor applications. Available as a concentrate, this primer can be mixed at the jobsite with clean water or used in its full concentrate form, depending on the condition and porosity of the substrate. Protecto Universal Water Based Primer - A high tack water based primer. Packaging Whisper Mat CS is available in 36" × 40' (914 mm × 12.2 m) rolls Coverage Whisper Mat CS Approximate 120 ft2 (13 m2) per roll Shelf Life Whisper Mat CS maintains optimum initial adhesion to substrates when used within one year from the date of manufacture. Uses • For sound control and crack isolation protection on interior applications under thin set ceramic and dimensional stone tile installations Advantages • Reduces impact and airborne sound transmissions • Has the flexibility and strength to withstand structural movement and concrete shrinkage cracks up to 3/8” without transferring stress load to finished tile. • Can be installed with radiant heat floor systems • Provides a Light Commercial Load Rating per Robinson test • Anti-microbial coating and non-wicking fabric top makes an excellent bonding WHISPER MAT® CS 03/20/2023 04/24/ 2 0 2 3 sami Data Sheets are subject to change without notice.

(tested by “Calcium Chloride Test” method), where constant water vapor transmission is present or a relative humidity level of more than 75% of slab, these conditions must be mitigated prior to Whisper Mat CS installation. • Do not use under mortar beds thicker than 3/8”, installations requiring more than 3/8” of thin-set mortar need to be raised with a self-leveling compound or a pre-mortar bed and allowed to cure prior to installation • Do not use solvent-based sealants on or around Whisper Mat CS as they may deteriorate the product • Do not install over wet primer • Existing cracks larger than 3/16" should be prepared with proper backing material prior to installation of membrane • Not for use over expansion or structural movement joints 4.

Assemblies over which Whisper Mat CS will be installed shall be in conformance with the International Residential Code (IRC) for residential applications, the International Building Code (IBC) for commercial applications, or applicable building codes. Perimeter and field movement joints are to be installed in accordance with TCNA Method EJ171. • Flooring and membrane must acclimate to jobsite conditions before installation. substrates must be dry, clean and free of dirt, grease, wax, paint, oil or loose foreign matter that would adversely affect adhesion of the Whisper Mat CS. Not for use on concrete floors when hydrostatic head pressure or excessive water vapor transmission exceeds 4lbs. (tested by ASTM E1869 “Calcium Chloride Test” method), where constant water vapor transmission is present or an RH level of more than 75% of slab, these conditions must be mitigated prior to Whisper Mat CS installation. Priming Always apply the Protecto Wrap No. 6000 Primer or Protecto Universal Water Based Primer to the substrate and allow to dry (approximately 30 minutes) before installing the Whisper Mat CS to ensure a good bond. Contractor must test for proper adhesion. Layout Unroll Whisper Mat CS with the release liner side down. Precut the length slightly longer than the distance to be covered. Trim membrane to fit against walls and cutouts within ¼”. Fold back half of the length of the roll back over the other half of the material. Score through the release liner only and take care not to cut completely through membrane. Application Pull release liner away from membrane where scored. As the release liner is pulled away, hand-smooth the membrane to contact the primed substrate. Keep the release liner material close to the floor while pulling away; this will allow for a more controlled application of the membrane. Align membranes in a butt joint fashion making sure not to overlap seams. Note - There will be an immediate and aggressive bond of the membrane to the primed substrate. Realignment of the membrane can be difficult once adherence to the substrate begins. After Whisper Mat CS is installed, ceramic, porcelain or stone tiles can be installed in a 3/8” or less bed of mortar that meets the ANSI 118.4 standards. Follow the TCNA and ANSI installation requirements through the remainder of the installation. 6.
