The substrate must be clean and stiff. Concrete and masonry must be cured for no less than 3 months; plasterwork and screed, for no less than 28 days. Prior to applying the waterproofing finishing, it is necessary to clean the surface from crumbling elements, grease stains, and other contamination that prevent adhesion of the material to the surface. Cold joints and cracks must be prepared in compliance with the working method. Corner areas must be rounded off by means of cement-mortar rounding-off shoulders (angle fillets with a radius of no less than 3 cm); on quoins, bevel edges at the angle of 45° must be made.
In order to prepare the mortar, the contents of the bag must be poured into a tank with clean water at a rate of 0.18-0.20 liter per kg while constantly mixing. The mortar must be mixed either mechanically (with the use of an industrial-grade mixer) or manually. The mortar must be set aside to cure for 3-5 minutes and then re-mixed. Then, the mortar is ready for use. The mortar must be used within 1 hour from the moment of pre-mixing with water. In case of increased viscosity of the mortar in the tank (within the life time of the mortar), it is necessary to remix the mortar without adding water. Only clean capacities, tools, and water must be used for the preparation of the mortar.
The prepared solution is applied with the use of a brush in 2-3 layers. Each subsequent layer must be applied depending on external conditions but not earlier than 1 hour after the previous layer. The recommended thickness of the waterproofing coating is 3-4 mm. In the course of implementation of the work and in the next two days, the air and the substrate surface temperature must be between +5 °C and +30 °C. In the process of hardening (at least, 24 hours), the surface must be kept moist and protected from rain, direct sunlight, and frost effect. After 3 days following the installation of the waterproofing layer, additional layers may be installed.
