The foundation is prepared in accordance with DSTU-NB A.3.1- 23:2013 and DSTU-NB V.2.6-212:2016. The surface of the base must be dry, strong, even, with low and uniform water absorption. Before applying the dry mixture, the surface is cleaned of dust, oil stains and other substances that reduce adhesion. Surfaces made of porous concrete, as well as gypsum and smooth concrete surfaces should be treated with a primer. Leave primed surfaces for at least 4 hours before starting cladding.
Preparation of mortar mixture: pour water into a clean container (water temperature from +15 °C to +25 °C) at the rate of 0.20-0.22 l (l) per 1 kg (kg) of dry mixture (5.0-5 .5 l (l) per 25 kg (kg)), gradually add the dry mixture and mix with a low-speed mixer until a homogeneous mass without lumps is obtained. Keep the solution mixture for about 5 minutes, then mix again.
The use of dry mixture is recommended at temperatures from +5 °C to +30 °C and relative air humidity not higher than 65%. Eyes and skin should be protected during work. If the mixture gets into the eyes, it is necessary to immediately wash them with water and consult a doctor.
The mortar mixture is applied in a thin layer on the prepared base using a metal spatula or grater and smoothed with a toothed spatula. At one time, such amount of solution is applied that can be used within 15 minutes. Do not pre-soak the tile. After applying the solution, the tile should be applied and pressed to the base. The location of the tile can be adjusted within approximately 10 minutes after gluing it. The maximum thickness of the freshly applied mortar mixture under the tile should not exceed 10 mm. The minimum thickness of the layer should be at least 2 mm. For convenience, the width of the seam between the tiles is set using distance crosses. Remains of the solution mixture must be carefully removed with a damp sponge before it hardens. Grout of joints must be started no earlier than 24 hours after laying the tiles. When performing work, it is also necessary to comply with the requirements of the current regulatory documentation.
Paper bags with an inner polyethylene layer of 25 kg.
The mixture must be stored in original branded sealed package in a dry room, on pallets. The shelf life is 12 months from the date of manufacture indicated on the package
On average, 1.5 kg of glue is used per 1 m2, depending on the thickness of the applied layer and the condition of the surface.
