Mixture C-25 is used for fixing the cladding of walls and floors from ceramic, stone, stone-ceramic tiles inside and outside the building. It is recommended to use Adhesive cement on places where an increased adhesion of the solution is needed, for example when fixing tiles more than 30 × 30 cm, tiles on heated floors, balconies, terraces, external staircases, prefabricated concrete structures.
The time of use is up to 5 hours.
The temperature of the substrate is from 0C to 400C.
Operation – after 72 hours (during applying works on the system of heated floors, holding for at least 14 days).
The recommended layer is 30-10 mm.
Frost resistance – 50 cycles.
Consumption – about 8 kg / m2 with a layer thickness of 5 mm.
Proportion with water – 0.5 l / kg mixture.
PREPARATION OF FOUNDATION
The substrate must be flat, free from greasy materials, the moisture content of the substrate is less than 2% (for cement bases) and less than 0.5% (for gypsum bases). Exposure of bases: plaster, cement floors – more than 20 days, concrete – 6 months, and plaster coating – 7 days. Before starting work, the substrate should be pre-moistened. Cellular concrete, gypsum plaster and chipboard should be primed.
IMPLEMENTATION OF WORKS
Mix the dry blend with pure water in a proportion of 0.5 l / kg until a homogeneous mass is obtained. Spread on the prepared base with a spatula. In the case of laying tiles outside and indoor places that are dulling and freezing, the layer should be applied to the tile. Tiles do not pre-soak. Adjustment of laying can be carried out after 10 minutes. Tiles should be laid after 15 minutes from the moment the base of the mortar is received.
Work should be performed at a temperature of + 50C to + 300C. All the above recommendations are effective at a temperature of +20 ° C and a relative humidity of 60%. In other conditions, the time of grasping and hardening can change.
Store the blend in branded bags in a dry places. The warranty period of storage is 12 months from the production date.
