SikaTile®-100 Moisture Guard
FAST DRYING ELASTOMERIC WATERPROOFING AND CRACK ISOLATION MEMBRANE
0.0 (0)
SikaTile®-100 Moisture Guard is a single component, fast-drying, thin mil, load-bearing waterproofing, and crack isolation membrane for installation under ceramic tile or stone in residential, commercial, and industrial environments. With excellent elongation, adhesion, and high strength properties, SikaTile®-100 Moisture Guard provides a thin, continuous barrier to protect adjacent rooms and floors below from water damage. For common change of plane areas such as coves, corners, cracks, and drains, it can be combined with optional Reinforcing Fabric to provide additional protection. SikaTile®-100 Moisture Guard dries in 2 to 4 hours depending on ambient conditions and is then ready to receive any Sika polymer or epoxy mortar. SikaTile®-100 Moisture Guard is IAPMO-listed for use as a shower-pan liner, can be flood-tested after 4 to 6 hours of drying time, and exceeds ANSI A118.10 and ANSI A118.12 standards.

Usage
SikaTile®-100 Moisture Guard may be installed over any sound substrate normally acceptable to receive ceramic, quarry, porcelain, and stone tiles as a fast drying, 100% waterproof membrane for shower pans and other load bearing waterproofing applications. When installed in accordance with manufacturer’s specifications, SikaTile®-100 Moisture Guard will inhibit transferring of shrinkage and non-structural cracks caused by horizontal movement, when tile and stone finishes are used. Covers and protects most any architectural design forms or irregular shapes and is ideal for interior and exterior use in both residential and commercial applications.

Application
Cure Time
SikaTile®-100 Moisture Guard is dry when it turns light blue, with no visible dark color as applied. Typically, drying time is 2 to 4 hours; depending on ambient conditions. Extreme cold and humid conditions will extend drying time up to as much as 12 hours. After the second coat is applied and both coats are fully cured, the application area can be flood tested.
Drying Time
2 - 4 hours*
*When cured at 70 º F (21 º C) and 50% RH. Ambient conditions may speed or slow drying times.
Coverage
50 sq. ft. per gallon at 30 mils thick
SUBSTRATE PREPARATION
All surfaces must be between 40º F (4º C) to 90º F (32º C) and structurally sound (deflection not to exceed 1⁄360 of the span), dry, clean, and free from oil, grease, wax, paint, old adhesives, sealers, and curing compounds. Any contaminates which 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’. Patching, leveling or areas requiring a mortar bed should be prepared using SikaLevel® 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.
SUBSTRATES
Concrete Substrates: All concrete substrates should be cured a minimum of 28 days. Smooth steel troweled floors should be roughed up using mechanical chipping, scraping, or shot blasting. Dampen porous or dry concrete prior to installation of tile. 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. Concrete should be tested for both moisture vapor transmission and hydrostatic pressure, by use of a Calcium-Chloride (CaCl) test. Consult technical support if test readings indicate a reading greater than 5 lbs. per 1,000 sq. ft. in 24 hours. Existing joint openings larger than 3/16” must be prepared and filled with an approved caulking or sealant prior to the application of primer and elastomeric membrane.
Patching, Self-Leveling Compounds, Lightweight Gypsum Concrete: Should be cured to the minimum manufacture’s requirement for moisture sensitive installations.
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 of the span 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.
CLEANING OF TOOLS
Clean tools and tile with water before the material dries.
FAQ
If the plywood is acceptable as a substrate for ceramic tile and the deflection values are met, you may use any of the SikaTile® liquid-applied membranes over the plywood as a bond coat. See the SikaTile Technical Data Sheet for installation instructions.
Do not use liquid-applied membranes over hardwood flooring, particleboard, Masonite, plank flooring, treated plywood, vinyl, laminate flooring, floors containing asbestos, gypsum-based floor-patching compounds. Contact SikaTile® Technical Service at 201-933-8800 with any questions.
Yes. Any existing expansion joint or soft joint (saw cut) must be honored throughout the entire assembly per TCNA EJ-171. Expansion joints and saw cuts are part of the construction of the building and need to be kept in place.
Perimeter joints still need to be honored per TCNA EJ-171. Just because a crack-isolation membrane is used does not mean that the tile will stop expanding and contracting.
A crack-isolation membrane is a form of insurance. No matter how new or old your concrete substrate may be, it always moves through expansion, contraction and stress. When a crack appears or already exists and a hard product like tile or stone is applied over that substrate without protection, those cracks can transmit through the entire installation, creating unsightly fractures in the tile or grout.
Curing and drying are two different things. Drying can take just a few hours but curing can take up to 48 hours or longer. Although curing may take longer than drying, it does not mean that you need to wait for installation over the membrane. The curing will occur even when tile is installed.
SikaTile®-100 Moisture Guard can be flood tested four to six hours after the membrane has dried.
All grouts are not rated to resist water. Sealers are used to protect the grout from staining. Even if a grout is sealed, a liquid such as water could seep through where the grout meets the tile, causing damage to the substrate. Waterproof membranes are designed to protect the substrate and direct the water to a drain system.
Once the liquid-applied membrane has dried to the touch and does not transfer, you may begin installing a polymer-modified mortar.
Liquid-applied membranes are monolithic when applied and have no seams. Peel-and-stick (PNS) products are typically 36” wide and need to overlap for wider applications, creating a seam that could potentially leak. Liquid-applied membranes are also great for areas that may not be square or have a radius. PNS products do not conform to applications that have a radius or out-of-square area and will more than likely need to be folded, causing an area for potential leaks.
SikaTile® liquid-applied waterproofing and crack-isolation membranes should be applied at a wet-film mil gauge thickness of 30 mil for first coat. This includes embedded reinforcing fabric at change-of-plain areas. After the membrane has dried, a second application needs to be applied without fabric needs to be applied at 30-mil wet thickness for a total of 40-mil thickness after drying/curing.
Every manufacturer differs with their requirements for fabric embedded into a waterproofing membrane. The manufacturer's Technical Data Sheet and installation directions will describe if a fabric is needed. SikaTile® highly suggests that a reinforcing fabric be used at every change of plane to ensure maximum protection at joints, cracks, protrusions, dissimilar materials, and drains.
