After the primer coat dries, CLASS BT-910 should be applied undiluted; evenly over the entire surface in at least 2 coats using a brush, trowel, or spray. The second coat application should only proceed once the first coat is completely dry. In areas exposed to temporary and continuous water pressure, to achieve an application thickness of 4 mm, an alkali-resistant fiberglass reinforcement mesh with a maximum weight of 110 g/m² must be embedded across the entire surface following the first coat of CLASS BT-910, and the second coat of CLASS BT-910 must be applied to completely cover the mesh.
