Quick set cement-based self-levelling underlayment for thicknesses from 3 to 30 mm, for interiors
SM 485 is used for interiors to level uneven cementitious substrates or old ceramic floors, with a thickness of application between 3 and 30 mm, when rapid drying time is necessary to allow the floor covering to be laid quickly. Floor coverings can be laid only after the complete drying of the product. The drying time depends on the thickness, the water content of the mix and the thermo-hygrometric conditions (varying from some days to some weeks). It is advisable to measure the actual moisture with a carbide hygrometer, before laying the floor covering.
