At least three layers are required, regardless of whether the bottom or wall is being waterproofed. ALPOL AH 753 waterproof mortar is essential for waterproofing.

The mortar is a two-component product. To prepare for application, pour the liquid component into a container and add powdered component while simultaneously stirring with the use of a low-speed electric drill with a basket mixer until homogeneous mix is achieved (mixing time around 3-4 minutes). Allow 5 minutes and mix again. The collective package contains components in a ready-to-mix proportion. To reach a sludge consistency, 3% water may be added while applying the first coat. Apply at least two coats of the compound. In case of swimming pools, application of three coats is recommended. 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. Use a notched trowel with 4 mm notch height for easier control of the product coverage. Depending on particular use, the total thickness of the waterproofing coat after drying should be between 2 and 3 mm. Spraying equipment can be used to apply the mortar 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 on horizontal surfaces in swimming pools, with ALPOL AK 516 quick-setting liquefied thin-layer adhesive 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.
