High-quality, highly elastic (S2) lightweight cement-based tile adhesive (C), composed of special quartz-based sand, synthetic resins, specific additives, with improved adhesive strength (2), slip resistance (T) and long working time (E). It is characterized by excellent workability and uniform hardness. Classified as C2TES2 adhesive according to standard EN 12004.
LIGHTKOLL C2TES2
Suitable for bonding ceramic tiles on cement-based substrates, porcelain stoneware, clinker, marble, stone tiles, mosaics, low-absorption tiles, high-thickness tiles, for floors and walls, in external and internal environments as well as on waterproofing layers (e.g. Hidrofix II). Recommended for high facades, terraces, for environments with central heating, for environments that are subject to constant vibrations, pressures, (this is as a result of its high elasticity and deformability). Suitable for bonding large-sized tiles. Suitable for bonding tiles of 5-200 cm format.
Mix 6.5-7 l of clean water with 15 kg of Lightkoll, with an electric mixer until a homogeneous mass is formed. The resulting mass is left to stand for 10 minutes and it is recommended to mix again before use. The working time is 4 hours.
Cement-based substrates must be stable, resistant and regular, free of oils and dirt and free of paint residues and must have reached the maturity time in advance. Approximately traditional cement-based floors with normal hardening time must have a curing time of at least 28 days, traditional plaster bases must dry for at least 14 days. Large unevenness or large cracks must be repaired in advance. All types of substrates must be cleaned in advance before applying the product mechanically. Before applying the product, the surface of the substrate must be moistened so that the product can create the best possible adhesion to it.
Application
Initially, it is recommended to apply the product with the straight part of the trowel to have a more uniform distribution and then with the notched part. The application is done with a suitable trowel depending on the type of tile being laid. The tiles are placed by exerting a slight pressure on the tile, ensuring that the tile is covered over the entire surface with the trowel. The opening time of the product under normal atmospheric conditions is 35 minutes for a temperature of 23°C. Atmospheric conditions can affect the drying time of the product. Care must be taken that the trowel does not form a film surface. Otherwise, it is necessary to pass the trowel over the trowel once more. It is not advisable to place the tiles with overlapping joints. The tiles are placed in such a way that they are suitable for their dimensions. A distance of 5 mm must be left on the surfaces of the joints with vertical walls.

Attention! For very large tile formats, apply a double layer of glue to the tile and the base. Protect the base for at least 24 hours after applying the adhesive, from driving rain as well as from frost and strong sunlight. For large tile formats, the grouting will be done 4-5 days after gluing only if waterproofing has been done.
