Self -leveling Fassa SM485 For thicknesses from 3 to 30 mm for internal floors sold in 25kg bags.
Self -leveling Fassa SM485 It is a dry premishable composed of special socket and quick hydraulic binders and selected sands.
USE
SM 485 is used to level irregular cement bases inside or old ceramic floors, with thicknesses of use from 3 to 30 mm, when a short drying time is required to allow a subsequent quick laying of the floors. The laying of the floors is possible only after complete drying; The time necessary depends on the thickness, the amount of water of the dough and the thermo-hygrometric conditions (from a few days to a few weeks). We measure the measurement with carbide hygrometer before proceeding with the laying of the coating.
Processing
Pour and simultaneously mix a 25 kg sack of SM485 in about 4.5-5 liters of clean water and mix with mechanical agitator or with slow speed machine until it is obtained a homogeneous lump-free dough. Greater quantities of sm 485 can be mixed in common mixers for mortars. SM 485 can also be applied with pump. Do not try to restore the lost workability by adding further water to the dough. Wait 2 minutes before the application and then shake the dough. SM 485 is easily spreads into a single hand in thicknesses from 3 to 30 mm with metal spatula or Racla. For its high self -leveling qualities SM 485 leaves no imperfections. Since it is a quick product the laying of wooden floors, ceramics, etc. It can be made just a short time from the application (1 to 3 days depending on the thickness and temperature): it is still necessary to lay the floors only after having ascertained the actual drying with carbide hygrometer.
