Tile & Stone Installation

(CSM 110) Sound Control and Anti-Fracture Membrane System

(CSM 110) SGM Sound Control and Anti-Fracture Membrane System is a self-adhering “peel-and-stick” membrane that consists of a base layer of polymer modified elastomers permanently laminated to a unique “stress flex” fiber sheet. This forms a single, high performance, self-bonding membrane over which ceramic tile or dimension stone can be installed immediately after placement with a latex-modified Portland Cement mortar.

Exceeds Florida Building Code 1207.3 requirements.

  • Interior Use Only: Concrete, mortar beds, exterior glue plywood, cement backer board, cement terrazzo, ceramic tile and stone, oriented strand board (OSB).


  • Do not apply over marine-grade plywood, Luan, Masonite, laminate, metal, or fiberglass surfaces.
  • Not for use under agglomerate tile, LVT, cement, and epoxy floor topping systems.
  • Not for use as a waterproofing membrane.
  • Not for use on concrete floors where hydrostatic pressure exists or where moisture vapor transmission exceeds four (4) pounds.
  • Do not use under mortar beds thicker than ? inch; installations requiring more than ? inch 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 or sealers where contact with membrane may occur.
  • Do not install over wet primer.
  • Existing cracks larger than 3/16 inch should be prepared with proper backing material prior to installation of membrane.
  • Not for use over expansion or structural movement joints.



Subfloor must conform to ANSI 108.01 standards. Assemblies over which Anti-Fracture Membrane (AFM) 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 the Tile Council of North America (TCNA) Handbook 2019, Method EJ 171. Flooring and membrane must acclimate to jobsite conditions before installation. Concrete subfloors must be dry, clean, and free of dirt, grease, wax, paint, oil, or anything that would adversely affect adhesion of the SGM Crack Suppression Membrane System (CS 40). Check subfloor for excessive moisture using ASTM E1869 Standard Test Method for measuring moisture vapor emission rate of concrete subfloor using Anhydrous Calcium Chloride. Readings must be less than four (4) pounds.

  • Priming: Interior Primer should be applied with a short nap roller, flat trowel, brush applicator, or sprayer. Substrate temperature should be at least 65°F (sixty-five degrees Fahrenheit). Prime only an area that will be covered by membrane within four (4) hours. Apply a thin film of uniform thickness to substrate in single strokes. Do not re-roll primer. Air pockets may form if membrane is installed over wet primer. Allow primer to dry until tacky to touch, but non-transferable to finger. This may take as little as ten (10) minutes, but usually no more than forty-five (45) minutes, depending upon temperature, humidity, internal moisture level/porosity of substrate, and application thickness. See primer labels for additional information. Slit release paper and allow membrane to roll out, adhesive-side down, across primed floor. Press membrane into place with using a 75-100# Roller.
  • Layout: Unroll Sound Control and Anti-Fracture Membrane System (CS 110) with release liner side down. Cut the length approximately twelve (12) inches longer than the distance to be covered. Trim membrane to fit tightly against the walls and cutouts (within ¼ inch). 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 the membrane.


Pull release liner away from membrane where scored. As the release liner is pulled away, hand-smooth the membrane to contact the primed subfloor. 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 the seams.

  • NOTE: There will be an immediate and aggressive bond of the membrane to the primed subfloor. Realignment of the membrane can be difficult once adherence to the subfloor begins. After Sound Control and Anti-Fracture Membrane System (CS 110) is installed, ceramic, porcelain, or stone tiles can be installed in a ? inch or less bed of mortar that meets the ANSI 118.4 standards. Follow the Tile Council of North America (TCNA) Handbook 2019 and ANSI installation requirements through the remainder of the installation.


Not recommended for use on concrete floors with excessive moisture vapor transmission or excessive hydrostatic head pressure. Protect floors from traffic until new floor is fully cured. Large format tile (LFT) installations may require extended cure time. Membrane and companion products must be protected from elements until tile is installed, grouted and cured. SGM must be contacted for special instructions prior to application of a leveler or patching compound to membrane. Do not use petroleum-based cleaners or sealers for tile, marble, stone, or grout. Impervious tile (less than 0.5% absorption) requires a 48-hour cure time prior to grouting. Protect floors from heavy construction equipment during installation to prevent damage.
