Description: MONOFLEX-M is a thixotropic powder adhesive made up by cement, aggregate with selected granulometry, synthetic resins and special additives. MONOFLEX-M has been conceived and developed for quick and sure laying of almost all types of ceramic materials also onto non-absorbing substrates, or onto substrates that are subject to slight dimensional variations. Besides, the high resistance to vertical slippage allows tiling from the top down.

Primary Uses: MONOFLEX-M can be used for: • laying porcelain tiles and non-absorbing ceramic tiles. • interior or exterior laying of floor and wall ceramic tiles of all types even onto heated floors (hot water and electric radiant floor): - interior: largest size of the tiles 90 x 90 cm. For wall coverings and heated floors largest size of the tiles 60 x 60 cm. - exterior: largest size of the tiles 60 x 60 cm. For wall coverings the water absorption of the tiles must be less than 0.5%.

Application Procedures: Surface Preparation: Substrates should be free from dirt, paint, grease or wax. For laying on old floors of ceramic tiles, gres, marble or similar materials, it is necessary to ensure that these are properly fixed to the substrate, washed and degreased. It is indispensable always to leave a joint of at least 3 mm between tiles. For laying wall tiles it is

necessary to respect the expansion joints of the structure, the joints between wall and wall and between wall and floor; which should be filled up elastically. Leave movement joints or joints on the perimeter approx. every 20 m2. Mixing: Mix MONOFLEX-M with 26% of water (pour the powder in the water and not vice versa) until you obtain a homogeneous, bright, plastic adhesive. Leave it rest for 5 minutes, and then remix rapidly. MONOFLEX-M must be used within the pot life of 3 hours. Method of application: Tiling: INTERIOR: Lay the tiles while exerting a good pressure on the tiles surface, so that contact between tile and adhesive will be at least remove of 80% of their surface for wall coverings and of 95-100% for floor. EXTERIOR: The contact between tile and adhesive must be 95-100% so to avoid the eventual rain infiltrations that in case of frost could cause the detachment of the tiles. Therefore, it is suggested to spread also a layer of MONOFLEX-M on the back of the tiles. Same procedure is recommended indoors for: • floor tiles largest than 500 cm2 with water absorption of the tiles ≥ 0.5% (e.g. porcelain tiles). • floor tiles largest than 1100 cm2 with all the other types of tiles •w all tiles largest than 120 cm2 with water absorption of the tiles ≥ 0.5% (e.g. porcelain tiles). •w all tiles largest than 500 cm2 with all the other types of tiles. • s pecial applications such as industrial refrigerators, basins, swimming pools, etc. At +23° C and 50% of relative humidity the open time is of about 20 minutes. Under unfavourable conditions these time intervals can be reduced notably, therefore it is important to spread the adhesive gradually, using little quantities every time, and to verify often that it hasn‘t formed a superficial film before tiling. To improve the workability especially during the summer, it is useful to
damp the working place and to eliminate the eventual currents of air. During the first 48 hours following the laying, the adhesive cannot stand the frost. The floors laid with MONOFLEX-M can be open to foot-traffic cautiously after about 24 hours and for grouting after 48 hours (at temperatures below to +15° C) They are ready for normal traffic after 14 days. Cleaning and Equipment Maintenance: The cleaning of the coating of MONOFLEX-M must be effected by means of a damp cloth or sponge when the adhesive has already started to set and it can be done using greater quantity of water only after 48 hours from tiling. Estimating and Supply: Packaging: MONOFLEX-M is available in 25 kg poly-lined bags and 1,125 kg euro pallets loads. Consumption: It depends on the substrate and the type of trowel used. For smooth substrate and adhesive thickness of 5-6 mm, the coverage of MONOFLEX-M is 4-5 kg per m2 and it increases to 0,5-1 kg per m2 for rough substrates. Storage & shelf Life: MONOFLEX-M must be stored in the original unopened packaging in a dry and cool place. White version: 12 months from the date listed on the package; in conformity with the directive 2003/53/CE informing that this time expiration regards the efficiency of the reducing agent in respect to hydro-soluble chrome VI.
