At least after 24 hours from application of the last waterproofing layer. Note, however, that the specifications and instructions for use given on the package or in the data sheet, are valid for the temperature of (23±2) °C and relative air humidity of (65±5)%. The drying time may alter in different climate.

To reach a sludge consistency, 3% water may be added while applying the first coat. Apply at least two coats of ALPOL AH 753 sealing compound. Apply the first sludgy coat with a brush or a paintbrush, intensively rubbing the sealing compound into the substrate at the same time. Use stainless steel float to apply the second and the following coats of the compound having the consistency of putty. Remember to apply the following coats after the previous one is set, i.e. after around 6 hours. To avoid shrinkage cracks, do not apply more mortar than 2 kg/m² at a time. Depending on particular use, the total thickness of the waterproofing after drying should be between 2 and 3 mm. Spraying equipment can be used for application on large areas. The coat can be subjected to load after the time given in the “Technical data” table. It is recommended to bond ceramic cladding in swimming pools, on terraces, balconies and other horizontal surfaces with ALPOL AK 516 quick-setting liquefied thin-layer or ALPOL AK 517 quick-setting liquefied medium-layer adhesive. ALPOL AK 512, ALPOL AK 513, ALPOL AK 514, ALPOL AK 515 or ALPOL AK 518 flexible adhesives can be used as well.
