Health Precautions

RedGard Fabric Membrane installation requires the use of dry-set adhesive mortar. When using mortar, wear rubber gloves and eye protection. Avoid eye contact or prolonged contact with skin and wash thoroughly after handling. If eye contact occurs, flush with water for 15 minutes and consult a physician. Wash thoroughly after handling. Do not take internally. Keep out of the reach of children.

Limitations to the Product

  • RedGard Fabric Membrane will not accommodate deflection greater than specified in TCNA guidelines and should not be used as a wear surface or left otherwise exposed to construction traffic.
  • Some glass tiles and dimensionally weak and absorptive tiles or natural stone, may not be suitable for installation over a sheet membrane. Contact Technical Services for additional information.

Application of Product

All surfaces must be clean, smooth, and capable of supporting the finished tile installation. The adhesive mortar (thinset) used for installing RedGard Fabric Membrane must be appropriate for the substrate and  should thoroughly embed in the RedGard Fabric Membrane. To minimize installation duration, precut RedGard Fabric Membrane to size ahead of mixing adhesive mortar (thinset) for installation. Apply thin-set to the intended surface using a minimum 1/4" x 3/16" (6 mm x 5 mm) V- notched trowel. Rougher surfaces may require a larger notched trowel. Be sure to not allow mortar to skin over. Gypsum wall board should be wiped down with damp sponge prior to thin set being applied. Only spread out as much as can be covered in about 5 minutes. Using the flat side of a trowel or a taping knife, embed the RedGard Fabric Membrane into the wet mortar. Work the trowel or taping knife at angles out and away from the center taking care to work out any air that may have been trapped when the sheet was placed.

Seams: Waterproof seams may be installed by overlapping edges of  RedGard Seam Tape by at least 2” or by butting the joints and utilizing RedGard Seam Tape over the top of the joint.

Corners: For inside and outside corners, used pre-formed RedGard Fabric Membrane corners. Connect these corners at change of plane with the RedGard Fabric Seam Tape, overlap and use mortar.

Pipe and Valve Flashing: RedGard Fabric Mixing and Pipe Seal can be used to flash around any wall protrusions. The pre-cut  hole is ½” diameter but can be enlarged with scissors or a utility  knife. Hole in mixer and pipe seal should be tight around any protrusions. Fill any gaps or openings with CUSTOM® Commercial 100% Silicone Sealant for a watertight seal. Overlap and use mortar to join the fabrics

Circular Drain Treatment: Substrate is to be pre-sloped flush to the top of the drain flange prior to installing fabric. Lay fabric over the flange and cut drain opening and bolt hole openings. Remove fabric and apply adhesive mortar on the substrate up to drain flange edge. Apply a continuous bead of CUSTOM® Commercial 100% Silicone Sealant on top of the flange outside of the bolt hole diameter under where the clamping ring will seat.

Embed fabric into the mortar and sealant before the products set. Tighten clamping ring immediately and flatten fabric, mortar and sealant. Ensure that fabric follows the slope of the substrate without obstructing the flow of water to the drain.

Linear Drain Treatment:

Substrate is to be pre-sloped flush to the top of the drain flange prior to installing fabric. Lay fabric over the flange and cut drain opening. Remove fabric and apply adhesive mortar on the substrate up to drain flange edge. Apply a continuous bead of CUSTOM® Commercial 100% Silicone Sealant on top of the flange.

Embed fabric into the mortar and sealant before the products set. Flatten fabric over the mortar and sealant, ensuring that fabric follows the slope of the substrate without obstructing the flow of water to the drain.

Curing of Product

RedGard Fabric Membrane may be tiled as soon as it is installed. Flood testing should not occur sooner than 24 hours in moderate temperatures after installation of membrane to allow mortar to dry.

Cleaning of equipment

RedGard Fabric Membrane installation requires the use of dry-set adhesive mortar. Make sure to clean tools and hands with water before the material dries. Clean all spray equipment immediately after use.

Expected Wear

If tile or stone will not be set immediately after curing, protect the application from rain, direct sunlight and inclement weather for 72 hours after application. If delays longer than 72 hours are expected, cover the area with felt paper. Care should be taken to prevent the application from becoming soiled or punctured during and after application.
