40 Mil Peel And Stick Sound Control And Crack Isolation Sheet Membrane

SikaTile®-225 Fracture Guard PNS is a 40 mil (1 mm), thin, flexible, self-bonding, fabric reinforced, membrane that isolates ceramic and natural stone tile from cracks in the substrate. Suitable for both full and partial coverage applications. SikaTile®-225 Fracture Guard PNS is a crack isolation membrane that exceeds the requirements of ANSI A118.12 and protects tile from in plane movement up to 3⁄8” (9.5 mm). Its strong self-adhesive backing and uniquely designed surface provide secure bonding for all types of ceramic, natural stone, and terrazzo tile. After application, ceramic tile or stone can be installed immediately using appropriate SikaTile® polymer-modified cement-based mortar. Additionally, glue-down wood flooring can also be installed with approved urethane adhesives. SikaTile®-225 Fracture Guard PNS also reduces the transmission of impact and airborne sound through floors when installed under ceramic tile, stone, or wood floor coverings.

Read all installation instructions before installation. Place SikaTile®-225 Fracture Guard PNS with release paper still attached over the area to be treated. Unroll the membrane and cut leaving a 2”-3” excess at one end. Roll up ½ of the membrane, leaving the other half unrolled. Cut the release paper from the portion of the membrane and slowly pull the release paper toward you, exposing the tacky surface of the membrane and carefully attaching the membrane onto the primed surface, avoiding wrinkles and bubbles. Repeat the procedure with the unrolled portion of the membrane. Carefully butt edges (overlapping will cause the floor to become uneven). Immediately after installation press membrane into place working out from the center of the membrane by applying heavy pressure with the flat side of a trowel or a 100 lb. roller. Protect exposed membrane from dirt, traffic, and harmful elements until flooring is installed, grouted, and cured.

Finish Surface Installation
Apply finish flooring in compliance with methods of installation over crack-isolation membranes. Do not install any defective, damaged, or any finish flooring surface not for its intended use. The installation of this product does not eliminate the need for movement joints, including perimeter joints with a tiled surface.

SikaTile® elastomeric membranes, when properly installed in accordance with the following installation guidelines, will provide years of protection for finish flooring installations. In addition to these instructions, installers shall also reference the most current edition of American National Standards Institute (ANSI), Tile Council of North America (TCNA) Handbook for Ceramic Tile Installations, The Marble Institute of America (MIA) Dimension Stone Design Manual, NWFA (National Wood Flooring Association) and Manufacturer's instructions of selected setting materials, substrates, sub-floors, or other manufacturers being used in total, or any part of, an installed flooring system with SikaTile®. Consult your selected manufacturer of these above mentioned components to ensure selected products are compatible with SikaTile® elastomeric membranes.


Clean tools and tile with water before the material dries.
