Modified dry building mix ТМ MASTER. FLEX designed for facing walls and floors with ceramic tiles, tiles from natural and artificial stone on deformed bases inside and outside of buildings; installing under floor heating and stairs; facing furnaces and fireplaces; operations by the tile-by-tile method.



Surface preparation must be done in accordance with the State Building Standard of Ukraine DBN V.2.6-22-2001. The base must be:

- clean (remove dirt, flows, dust, fungal lesions with a power tool or manually);

- strong (remove all loose areas and process them with the primer ТМ MASTER or ТМ іMASTER;

- in presence of cracks, drops or irregularities treat the base with ТМ MASTER or ТМ iMASTER, and then align with the mineral mix ТМ MASTER. FRONT. Sandy (24 hours before the start of work);

- the surface with high water absorption and air temperature above +30 С require additional moisturizing;

- surfaces pretreated with primer ТМ MASTER or ТМ iMASTER do not require moistening.



Perform the work at an air temperature of +50С to +350С. The temperature of the base must be in the same range.

Add pure water to the dry mixture in an amount indicated in specifications, then mix it (use electric drills with screw socket). Leave closed mix for 5 minutes, and then stir again. The closed mix is suitable for use within 120 minutes (at recommended atmospheric conditions). At high temperatures, periodically stir the closed mix to avoid reducing its mobility.

For facing floors, the amount of water to prepare the mix is specified separately in the specifications.

Apply the closed mix ТМ MASTER. FLEX on the surface with a trowel, float or leveling plate, then spread with a notched trowel. Trowel notches must match the size of the tiles as per the table.

Apply the facing material on the applied mix and press with a force to the base. Do not apply tiles without joints. The joint between tiles must be at least 2 mm. Do not soak tiles in advance!

For outdoor use and for tiles with profiled back side we strongly recommended applying additional mix TM MASTER. FLEX with a thin layer (1-2 mm) directly on tiles. Conduct grouting between tiles no earlier than 24 hours after tiling. We recommend using grout ТМ iMASTER.

In case of facing floors, displacement is possible not earlier than after 48 hours.
