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 40°F (4°C) to 90°F (32°C) 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.
Refer to the individual waterproofing membrane Product Data Sheet (PDS) the SikaTile®-150 Moisture Guard Fabric DH is intended to be used with.
APPLICATION
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).
PROTECTION
Protect from traffic, dirt, or dust from other trades until the final installation of the floor covering.
LIMITATIONS
- Do not use below 40°F (4°C); do not allow membrane or substrate to be below 40°F (4°C) for the first 72 hours after application.
- Do not install over substrates containing asbestos.
- Refer to the individual waterproofing membrane Product Data Sheet (PDS) the SikaTile®-150 Moisture Guard Fabric DH is intended to be used with.
