INSTALLATION

SikaTile® membranes, when properly installed in accordance with the following installation guidelines, provide years of protection for finish flooring and wall 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 floor and wall system with SikaTile®. Consult your selected manufacturer of these previously mentioned components to ensure selected products are compatible with SikaTile® membranes.

SURFACE PREPARATION

All surfaces must be between 40ºF (4ºC) to 90ºF (32ºC) and structurally sound (deflection not to exceed L⁄360 for ceramic and porcelain tiles and L/720 for natural stone), dry, clean, and free from oil, grease, wax, paint, old adhesives, sealers, and curing compounds. Any contaminants that inhibit proper bond must be removed. Substrate preparation should be completed following ANSI A108 AN-2 “General Requirements for Sub-surfaces.” All substrates should be plumb and true; surface deviation should not exceed 1⁄4" in 10’ or 1/8” in 10’ for large format tiles. Patching, leveling or areas requiring a mortar bed should be prepared using Sika® underlayments. Movement (expansion) joints should be provided to comply with TCNA method EJ171. Concrete must be free of any negative hydrostatic pressure and/or excessive moisture.

Installations with drains require a minimum slope of 1/4" per foot (6 mm per 0.30 m) toward the drain. For waterproofing applications refer to TCNA Handbook, ANSI Standards and local codes for requirements.

SUBSTRATES

Concrete Substrates: All concrete substrates should be cured a minimum of 28 days. Smooth steel troweled floors should be roughed up using mechanical grinding or shot blasting. Dampen porous or dry concrete before starting the installation. Do not leave puddles or standing water. Rough or uneven surfaces should be made smooth with a latex Portland cement underlayment to provide a wood float or better finish. Do not level with asphalt-based products. Existing joint openings larger than 3/16” must be prepared and filled with an approved caulking or sealant before application of SikaTile®-150 Moisture Guard Fabric Membrane (refer to EJ-171 details in the TCNA Handbook).

Patching, Self-Leveling Compounds, Lightweight Gypsum Concrete: Should be cured to the minimum manufacturer’s requirement for moisture-sensitive installations. Gypsum wall board should be primed and wiped down with damp sponge prior to thin set being applied.

Plywood and OSB Substrates: Must be a minimum of two (2) layers 5/8” exterior grade plywood (EGP). Plywood shall be securely fastened in accordance with industry standards. Maintain a 1/8” gap between plywood sheets and all surfaces they abut. Joints in the top layer should be offset from the joints on the bottom layer. Maximum joist spacing should be 16” on center and the deflection of the floor structure and sub-floor must not exceed L⁄360 for ceramic and porcelain tiles and L/720 for natural stone under combined live or dead loads.

Other Substrates: All other substrates and or sub-flooring systems shall be installed in a manner approved by both the product manufacturer and using appropriate installation method.

Cracks & Joints: Treat all cracks and joints by filling substrate cracks, cold joints, and control joints to a smooth finish using Sikaflex 11-FC or approved urethane sealant prior to the application of SikaTile®-150 Moisture Guard Fabric Membrane.

MEMBRANE APPLICATION

Read all installation instructions thoroughly prior to installation.

• Measure and cut all SikaTile®-150 Moisture Guard Fabric Membrane sections to the proper length before mixing the appropriate SikaTile® mortar. Make sure to allow for upturns and 2" (5 cm) overlaps or use SikaTile®-150 Moisture Guard Fabric ST (Sealing Tape) instead of upturns and edge overlaps.

• Mix a suitable SikaTile® polymer-modified mortar meeting at least ANSI A118.4 or ANSI 118.11 to a consistency using 10% to 20% additional water than the recommended water range, to hold a notched ridge while allowing for wetting out of the fabric layer backing of the membrane.

• Key SikaTile® mortar into the substrate with pressure by using the flat side of the trowel.

• Apply additional mortar, combing it in a single direction using a 1/4" x 3/16" (6 x 5 mm) V-notched trowel. Spread only as much mortar as can be covered with SikaTile®-150 Moisture Guard Fabric Membrane before the mortar skins over. Rougher surfaces may require a larger notched trowel. Open times vary by mortar and jobsite conditions.

• Embed SikaTile®-150 Moisture Guard Fabric Membrane into the mortar. Using a rubber or wooden float, plastic taping knife or hand roller, move slowly and apply pressure and ensure proper embedding of the membrane. Work from the middle to the outside edges to ensure that air is not trapped underneath the membrane. Occasionally lift membrane to verify coverage and ensure full contact between the fabric membrane and mortar.

• Bond the seams by overlapping the edges of the SikaTile®-150 Moisture Guard Fabric Membrane by 2" (5 cm) or embed SikaTile®-150 Moisture Guard Fabric ST sealing tape over the abutted edges without leaving gaps with the SikaTile® mortar using a 1/4" x 3/16" (6 x 5 mm) V-notched trowel, key in the mortar to the adjoining seams with the trowel’s flat side. Apply mortar on top of the seams with the trowel’s notched side. Center the tape over the seam with at least 2" (5 cm) on each side of the seam and apply the tape. Work the sealing tape or 2" (5 cm) overlap into the thin-set mortar with a grout float, plastic taping knife or the trowel’s flat side while the thin-set is still workable.

• Use a damp sponge to clean excess mortar from areas on the SikaTile®-150 Moisture Guard Fabric Membrane.

• Fill any gaps or openings with Sikaflex®-11 FC Sealant for a watertight seal.

Floor and Wall Connections:

• Use SikaTile®-150 Moisture Guard Fabric ST sealing tape or overlap seams by at least 2" (5 cm) at the corner of where the floor and wall meet.

• For inside and outside corners, adhere SikaTile®-150 Moisture Guard Fabric IC pre-formed inside corners and SikaTile®-150 Moisture Guard Fabric OC pre-formed outside corners using appropriate SikaTile® mortar.

• Install SikaTile®-150 Moisture Guard Fabric PC pre-formed pipe collars to seal pipes at showerheads, hand-held sprays, etc., and SikaTile®-150 Moisture Guard Fabric MVC pre-formed mixing valve collars using appropriate SikaTile® mortar.

• Fill any gaps or openings with Sikaflex®-11 FC Sealant for a watertight seal.

DRAIN TREATMENTS

Bonding Flange Drain:

• Substrate is to be pre-sloped flush to the top of the bonded flange drain before installing SikaTile®-150 Moisture Guard Fabric Membrane. Lay fabric over the flange and cut drain opening and bolt hole openings. Remove fabric and apply appropriate SikaTile® mortar on the substrate up to drain flange edge. Apply a continuous bead of Sikaflex®-11 FC 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:

• Substrate is to be pre-sloped flush to the top of the drain flange before installing SikaTile®-150 Moisture Guard Fabric Membrane. Lay fabric over the flange and cut drain opening. Remove fabric and apply SikaTile® mortar on the substrate up to drain flange edge. Apply a continuous bead of Sikaflex®-11 FC 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.

Clamping Ring Drain:

• Substrate is to be pre-sloped flush to the top of the drain flange before installing SikaTile®-150 Moisture Guard Fabric Membrane.

• Lay SikaTile®-150 Moisture Guard Fabric Membrane over the top of the drain and cut an X where each bolt will penetrate the membrane. Cut a hole in the membrane to allow the drain grate to be threaded into the clamping ring. (Use of a fabric circle cutter is recommended.)

• Embed SikaTile®-150 Moisture Guard Fabric Membrane, making sure to align the previously cut holes for the bolts and drain throat. Remove fabric and apply appropriate SikaTile® mortar on the substrate up to drain flange edge.

• Apply a continuous bead of Sikaflex®-11 FC 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.

• Check to make sure that weep holes are not plugged by any material. Install final mortar bed slope to the drain, protecting weep holes by using pea gravel or crushed stone. Once mortar bed is dry, tile installation can begin.

Clamping Ring Drain Using Divot Method:

• With the bottom portion of a standard clamping ring in place and sitting on the substrate, a bonded or non-bonded mortar bed of SikaTile®-910 Floor Mud with a divot around the drain should be installed around the clamping ring body.

• Mortar bed should be sloped at 1/4" per foot (6 mm per 30.5 cm).

• Place a bead of Sikaflex®-11 FC Sealant on the top surface of the body of the clamping ring outside of the clamping ring throat being careful not to block any weep holes.

• Place or SikaTile®-150 Moisture Guard Fabric DH - Deep Drawn Drain Collar over the standard clamping ringbolts and cut a 1/2" (12.5 mm) X through the fabric so the drain collar can slide over the bolts.

• Apply appropriate SikaTile® tile mortar with a 1/4" x 3/16" (6 mm x 5 mm) V-notched trowel over the mortar bed. Press the SikaTile®-150 Moisture Guard Fabric DH Deep Drawn Drain Collar firmly into the SikaTile® mortar. Remove any trapped air to ensure full adhesion to the Drain Collar material by spreading the SikaTile® mortar from the inside of the drain collar outward using a trowel or straightedge with rounded corners.

• Place another bead of Sikaflex®-11 FC Sealant on the underside of the top portion of the clamping ring, being careful not to block any weep holes. Place the top portion of the clamping ring over the Drain Collar and the bolts protruding up from the bottom portion of the clamping ring through the Drain Collar. Secure the clamping ring nuts and tighten as required.

• Cut a hole in the Drain Collar material to allow a drain grate to be threaded into the clamping ring. (Use of a fabric circle cutter is recommended.)

• Screw the drain grate into the clamping ring assembly to the desired height for tiling. Protect weep holes in the clamping ring drain from clogging by filling the recessed area around the drain grate with pea gravel and additional SikaTile® Floor Mud or equivalent.

• To provide a watertight assembly, particularly within the recessed area, cut a waterproofing membrane (e.g., SikaTile®-150 Moisture Guard Fabric Membrane) to cover the flooring from the walls up to the threaded drain grate so that the waterproofing membrane extends over the entire Deep Drawn Drain Collar (including portions thereof residing within the recessed area), over the standard clamping ring assembly (including over and inboard all outer edges of top and bottom clamping rings of such assembly), and over the mortar and pea gravel within the recessed area around the drain grate. Cutting the waterproofing membrane so that it fits tightly around the drain grate minimizes water seepage into the mortar and pea gravel within the divot region.

• Apply appropriate SikaTile® mortar with a 1/4"x 3/16" (6 mm x 5 mm) V-notched trowel over SikaTile®-910 Floor Mud mortar bed. Press the SikaTile®-150 Moisture Guard Fabric Membrane firmly into the tile mortar. Remove any trapped air to guarantee full adhesion to the material by spreading the SikaTile® mortar from the center of the fabric sheet membrane outward to the edges using a trowel or straightedge with rounded corners.

• Apply Sikaflex®-11 FC Sealant over the waterproofing membrane abutting the drain grate area to further provide a watertight assembly, particularly within the recessed area.

SikaTile®-150 Moisture Guard Fabric DH Deep Drawn Drain Collar is available in both 3/4" (19 mm) and 1-1/2” (38 mm) depths and a 17" (43 cm) diameter.

If flood testing is required, allow SikaTile®-150 Moisture Guard Fabric Membrane system to cure for at least 24 hours at 73°F (23°C) and 50% relative humidity (RH).

TILE INSTALLATION

Interior tile or stone installations can take place immediately after the installation of SikaTile®-150 Moisture Guard Fabric system.

Ceramic, porcelain and stone tile:

• Using a SikaTile® polymer-modified mortar suitable for the tile being installed, in accordance with the TCNA Handbook for Ceramic Tile Installation and with porcelain tile manufacturer’s instructions, skim the surfaces of SikaTile®-150 Moisture Guard Fabric Membrane using the flat side of the trowel, ensuring that the mortar is embedded into the fabric.

• Apply additional mortar and comb over the membrane in a single direction using the recommended notched trowel suited to the size and type of tile being installed. Install tile in accordance with industry guidelines.

Moisture-sensitive stone tile:

• Use SikaTile®-825 Epoxy Grout, 100%-solids epoxy setting mortar and grout, according to the Product Data Sheet instructions pertaining to the installation of moisture-sensitive stone or call Sika® Technical Service for installation information.

FLOOD TESTING (per ASTM D5957)

Flood testing is recommended before the finished floor is installed, even if not required. Allow SikaTile®-150 Moisture Guard Fabric Membrane system to cure at least 24 hours at 73°F (23°C) and 50% relative humidity. Actual curing time depends on air and substrate temperatures, substrate porosity and humidity. Expect shorter drying times in warmer conditions, and longer drying times in cooler conditions.

PROTECTION

Protect from traffic, dirt, or dust from other trades until the final installation of the floor covering.
