| Waterproofing / Antifracture |
AquaGuard is a ready to use, one component waterproofing and anti-fracture membrane composed of elastomeric polymers and proprietary chemicals. AquaGuard is trowel, brush, or roller applied to provide a continuous non-permeable waterproofing membrane to a variety of surfaces including concrete, masonry, steel, laminates and cement backerboards.
AquaGuard is used to waterproof existing interior or exterior wall and floor surfaces prior to the installation of ceramic tile, marble, stone, and resilient flooring. AquaGuard is also used as an anti-fracture membrane underneath thinset mortar applications or thickset “mud bed” installations. AquaGuard provides excellent flexibility which helps to prevent cracks in the substrate from transferring through to the tile. AquaGuard can be used to reduce moisture in concrete slabs subject to moisture transmission of 12 pounds or less, based on the Calcium Chloride Test (ASTM F1869.98). AquaGuard is ideal for the following uses:
- waterproofing commercial and residential kitchens
- waterproofing bathrooms and wet work areas in schools, hospitals, hotels, and office buildings and other commercial buildings.
- waterproofing porches, balconies, and decks.
- crack isolation membrane over cracks where movement does not exceed 1/8 inch

Surface Preparation |
Surfaces to receive AquaGuard must be clean and dry. Coatings, sealers, curing agents, and loose material must be removed prior to installation. Cracks in concrete up to 1/8” should be pre-filled with AquaGuard prior to application. Cracks in excess of 1/8” should be treated as expansion joints. Gaps between plywood sheets and where they meet walls or drains should also be pre-filled with AquaGuard. Extremely porous surfaces should be dampened slightly with water. All exterior and wet areas shall have proper slope to drains. All substrates must be secure and stable. |
| Limitations | AquaGuard should not be used over wet areas or where hydrostatic pressure exists. Do not apply if temperatures are expected to fall below 45 degrees within 48 hours of installation. Do not apply over presswood, particle board, luan plywood, or other unstable materials that are not suitable substrates to receive ceramic tile. Exterior grade plywood is an acceptable surface for only interior applications not subjected to wet areas. Use only on bare steel, not aluminum, copper, or galvanized surfaces. |
| Application |
Application - Waterproofing Membrane: Flashing: Using a brush, roller or trowel, pre-coat AquaGuard six inches in each direction, all inside and outside corners, where walls and floors or any horizontal and vertical surfaces meet such as benches, curbs and columns, etc. and where any dissimilar materials meet. Embed 6” wide fiberglass mesh into the wet AquaGuard membrane, 3-inches in each direction. Push the membrane into corners to assure full contact. Membrane Installation: Next, if using a trowel, spread the AquaGuard with a 3/16-inch V-notch trowel held at a 450 angle then flatten the ridges with the flat side of the trowel over the entire surface to be waterproofed, including flashing. If using a brush or 1/4 to 1/2 inch roller, apply a continuous, even film with overlapping strokes. Initial membrane appearance is an aqua color when wet and dries to a dark green color. The wet coat shall be 3/64-inch (47 mils) thick. After the first coat has turned green with no blushing or aqua color showing, about 1 to 2 hours, visually inspect the film and fill any voids or pinholes with additional material, then apply a second coat 3/64-inch (47 mils) thick wet coat at right angles to the first. The combined dried coating needs to be a minimum of 3/64-inch, but no more than 1/8-inch thick. Note: Coverage shall be no more than 40 sq.ft. per gallon for the two combined coats. This gives the proper dry thickness for waterproofing. Allow the second coat to dry approximately 2-4 hours (when the AquaGuard turns green) and tile or stone can then be installed using one of the Elite polymer modified thin-sets. Do not cover if water testing is required. See curing section. For Drains: Extend AquaGuard to the bottom of the drain flange taking care not to block weep and drain holes. Embed 6-inch wide fiberglass mesh into wet membrane around the drain making sure it does not obstruct the drainage hole. Then apply an additional coat of membrane over the mesh. After curing, clamp upper flange onto membrane and tighten. Caulk around flange where membrane and upper flange make contact with a silicone caulk. See TCA installation method for shower receptors. Application - Anti-Fracture Membrane: Use the same V-notch trowel or roller as for waterproofing, but only one uniform wet coat at 3/64-inch (47 mils) thick wet (approximately 1/32-inch dry) is required. The membrane can completely cover the substrate or for crack isolation, apply AquaGuard on both sides of the crack a minimum width of the diagonal measurement of the tile or stone. Allow to dry 1 to 2 hours and set the tile or stone with an Elite polymer modified thin-set. Application - Moisture Transmission Reduction: First, apply as a primer by diluting the AquaGuard using four parts clean water to one part AquaGuard. Completely coat the slab by using a stiff broom, roller or brush (coverage of 1-gallon of AquaGuard and 4-gallon water is 400-450 sq.ft.). After the primer coat is dry (usually within 1 hour), apply an additional coat of undiluted AquaGuard as directed above for waterproofing, at 3/64-inch wet. This will reduce the moisture transmission of 12 pounds or less, to a transmission of 3 pounds per 1,000 sq.ft. per day. Refer to the flooring material manufacturer for specific recommendations and testing procedures. Next, prior to installing vinyl, carpet and hardwood applications which require adhesives, install a 1/8-inch layer of Rapid Patch Underlayment following manufacturers instructions. All Expansion Joints, Control Joints: Clean the joint of debris. Next install compressible backer rod as outlined in EJ171 in the Tile Council Handbook, into the joint. Next, compress a sealant as specified by the architect into the joint leaving it flush with the surface. After the sealant is dry, cover the sealant with bond breaker tape. Apply a minimum 3/64-inch of AquaGuard over the joint and substrate following the instructions in the application section. Install the tile or stone onto the membrane but do not bridge the joint. After the tile or stone is set properly, fill the joint with colored caulk or sealant, following the architect and manufacturer’s instructions. |
| Protection | If tile is not going to be set immediately after curing, AquaGuard should be protected from rain and inclement weather for 72 hours after application. If delays longer than 72 hours are expected, cover with felt paper. Care should be taken to prevent membrane from becoming soiled or punctured during and after application. |
| Curing | 24 hours. A water test can be conducted 72 hours after application if required. |
| Coverage | 35 to 40 sq.ft. per gallon at 3/64”(47 mils) thickness for water-proofing. 70-80 sq.ft. at 1/32” for anti-fracture membrane. Increased performance: Reinforcing mesh may be used for increased performance in waterproofing or anti-fracture applications. Roll on one coat of AquaGuard, imbed Glass Fabric 32 reinforcing mesh, and roll on a final coat of AquaGuard to a total membrane thickness of 3/64-inch (47 mils). |
