WATERPROOFING AND CRACK ISOLATION MEMBRANE INSTALLATION Install waterproofing and crack isolation membrane in compliance with current revisions of ANSI A108.1 (2.7 Waterproofing), ANSI A108.13, and ANSI A108.17. Review the installation and plan the application sequence. Pre- cut LATICRETE Waterproofing/Anti-Fracture Fabric (if required), allowing 2” (50mm) for overlap at ends and sides to fit the areas as required. Roll up the pieces for easy handling and placement. Shake or stir HYDRO BAN ® before using. Pre-Treat Cracks and Joints - Fill all substrate cracks, cold joints and control joints to a smooth finish using a LATICRETE latex-fortified thin-set. Alternatively, a liberal coat* of HYDRO BAN applied with a paint brush or trowel may be used to fill in non-structural joints and cracks. Apply a liberal coat* of HYDRO BAN approximately 8” (200mm) wide over substrate cracks, cold joints, and control joints using a paint brush or heavy napped paint roller. Pre-Treat Coves and Floor/Wall Intersections - Fill all substrate coves and floor/wall transitions to a smooth finish and changes in plane using a LATICRETE latex-fortified thin-set. Alternatively, a liberal coat* of HYDRO BAN applied with a paint brush or trowel may be used to fill in cove joints and floor/wall transitions <1/8” (3mm) in width. Apply a liberal coat* of HYDRO BAN approximately 8” (200mm) wide over substrate cracks, cold joints, and control joints using a paint brush or heavy napped paint roller. Pre-Treat Drains - Drains must be of the clamping ring type, with weepers as per ASME A112.6.3. Apply a liberal coat* of HYDRO BAN around and over the bottom half of drain clamping ring. Cover with a second liberal coat of HYDRO BAN. When the HYDRO BAN dries, apply a bead of LATICRETE LATASIL ™ where the HYDRO BAN meets the drain throat. Install the top half of drain clamping ring. Pre-Treat Penetrations - Allow for a minimum 1/8” (3mm) space between drains, pipes, lights, or other penetrations and surrounding ceramic tile, stone or brick. Pack any gaps around pipes, lights or other penetrations with a LATICRETE latex-fortified thin-set. Apply a liberal coat* of HYDRO BAN around penetration opening. Cover the first coat with a second liberal coat* of LATICRETE ® HYDRO BAN ® . Bring HYDRO BAN up to level of tile or stone. When HYDRO BAN has dried to the touch seal with LATICRETE LATATSIL ™ Main Application - Allow any pre-treated areas to dry to the touch. Apply a liberal coat* of HYDRO BAN with a paint brush or heavy napped roller over substrate including pre-treated areas and allow to dry to the touch. Install another liberal coat* of HYDRO BAN over the first coat. Let the top coat of HYDRO BAN dry to the touch approximately 1 – 2 hours at 70°F (21°C) and 50% RH. When the top coat has dried to the touch inspect the surface for pinholes, voids, thin spots or other defects. HYDRO BAN will dry to an olive green color when fully cured. Use additional HYDRO BAN to seal any defects. Movement Joints - Apply a liberal coat* of HYDRO BAN, approximately 8” (200mm) wide over the areas. Then embed and loop the 6” (150mm) wide LATICRETE Waterproofing/Anti-Fracture Fabric and allow the HYDRO BAN liquid to bleed through. Immediately apply a second coat of HYDRO BAN. * Dry coat thickness is 20 – 30 mil (0.02 - 0.03” or 0.5 - 0.8mm); consumption per coat is approximately 0.01 gal/ft 2 (approx. 0.4 L/m 2 ); coverage is approximately 100 ft 2 /gal (approx. 2.5 m 2 / L). LATICRETE Waterproofing/Anti-Fracture Fabric can be used to pre-treat cracks, joints, curves, corners, drains, and penetrations with HYDRO BAN. Protection - Provide protection for newly installed membrane, even if covered with a thin-bed ceramic tile installation against exposure to rain or other water for a minimum of 2 hours at 70°F (21°C) and 50% RH. For temperatures between 45°F and 69°F (7°C to 21°C) allow a minimum 24 hour cure period.
