Ensure that all surfaces to which Vandex Uni Mortar 1-Z will be applied are pre-watered. The correct amount of prewatering is measured by the substrate taking on a greenish appearance, however there must be no free surface water. A simple check can be performed by placing a hand on the pre-watered substrate and removing the hand. If the hand is wet from contact with the substrate, then the substrate is too wet and must be allowed time for the excess surface water to evaporate. Surfaces that have been pre-watered and dry out before application of the Vandex Uni Mortar 1-Z must be pre-watered again. Apply the mixed Uni Mortar 1-Z from the base of the wall and work towards the top using a trowel or spray equipment. If a second application is required, allow the first layer to reach initial cure before applying a second layer. After 4 - 5 hours apply the second layer ‘green on green’ so that a chemical bond is achieved between the two layers. When applying Vandex Uni Mortar 1-Z by spray ensure that the gun is held directly perpendicular to the surface to ensure that the maximum impact energy is applied to the surface and to prevent any shadowing across surface imperfections. After application of the first coat by spray, brush or trowel the wet surface to remove any entrapped air. If other products are to be applied over Vandex Uni Mortar 1-Z, roughen the surface slightly by brushing or brooming the surface of the Uni Mortar 1-Z while it is still wet. The cure time of Vandex Uni Mortar 1-Z is affected by both temperature and humidity. Humidity has an influence on waiting times between layers and resistance to rain. Ensure that the freshly applied Uni Mortar 1-Z is protected from rain for the first day, and the drying effects of the sun and wind during the first 5 days of cure. In most waterproofing applications, Vandex Uni Mortar 1-Z is applied in one application by trowel or spray. Apply one layer by trowel or spray at an application rate of 12 - 24 kg / m² (Minimum layer thickness must be 6.0 mm). Curing and protection Surfaces treated with Vandex Uni Mortar 1-Z must be kept damp and must be protected from the drying action of direct sunlight for a minimum period of 5 days after application.
