    Applications Procedure

    "UltraTech - Seal & Dry" can be applied to the surface manually by brush. After application of 1st coat, allow a gap of minimum 2 hours, before the subsequent coat and it must be applied in perpendicular direction to the first coat.

    machine is recommended for better speed and economy. Care should be taken to avoid application under direct sunlight. The appropriate application time for the product is either early morning or late evening. This is to ensure that the water which is used for mixing does not evaporate fast and the product is able to develop the design properties. In case of U/G tanks, O/H tanks or basement, it is quite possible that drying time may increase more than 2 hours. In such cases, ensure that first coat is dried properly before the application of the second coat.

    It is advised to use brush with soft bristles and after the application the brush should be cleaned properly.
