Smooth Concrete Surface – Normal forming practice leaves a sufficiently smooth surface for direct bonding of Hydrotite using Leakmaster as an adhesive. Leakmaster works well when applied to dry or damp concrete surfaces. First, remove all dust, oil, laitance, etc. from concrete surface prior to installing Hydrotite. Apply a sufficient bead of Leakmaster to the concrete, and place the Hydrotite profile into position. Concrete nails may be used to hold the profile in position on vertical or overhead surfaces while the Leakmaster cures.
Rough Concrete Surface – Concrete surfaces left rough due to instances such as jackhammering, extensive weathering should be brought to a smooth level condition. Leakmaster can be used for this purpose when the concrete surface is dry. Apply a sufficient bead of Leakmaster to the rough concrete to ensure a smooth level surface. The Hydrotite profile should be placed in position within 4 hours. Concrete nails or special fasteners may be used on to hold the profile in position and on vertical or overhead surfaces to hold the profile in position while the Leakmaster cures.
Extremely Rough Surface – Two-part epoxy may also be used to level extremely erratic surfaces. Epoxy can be used on rough, damp concrete surfaces to bond Hydrotite into position. The Hydrotite profile should be applied to the bed of epoxy prior to final cure, which takes approximately 30 minutes. Concrete nails may be used on vertical or overhead applications.
In all three installation methods, installed Hydrotite profiles should be inspected to ensure that no separation exists between the Hydrotite profile and the substrate. If this is observed, apply a suitable bead of Leakmaster in the separation and secure with nails or special fasteners as required.
