Walkable: 12 hours approx.*
Laying of ceramic tiles: 24 hours approx.*
Laying of natural stone or marble: 48 hours approx.**
Laying of parquet: 4 days approx.***
* Times have been measured in ambient temperature +23C and R.H. 50%.
Higher temperatures reduce those times; oppositely, lower temperatures
increase them.
** For stones and marbles sensitive to humidity the time must be extended to 7
days.

Application Conditions
Methods of use
Substrate preparation
It is possible to achieve screeds adhering to the substrate or floating on a
separating layer, i.e. PVC membrane.
Mixing
Sika Screed Binder must be mixed with clean aggregate with continuous grain
size range from 0 to 8 mm in case of parquet laying. In case of tile laying the
grain size can be from 0 to 5 - 6 mm. The binder dosage is established to suit
the type of flooring.
If tiles or natural stones must be laid the dosage is 180 - 200 kg per m3 of
aggregates; if parquet or resilient materials must be laid the dosage is 250 kg
per m3 of aggregates. The product can be blended in an ordinary concrete mixer
or in a screw mixer of Turbosol type. The correct amount of water must be used
in order to get a plastic, highly workable paste.

Application
Compressible material must be positioned all round the edges of the room and
around any pillar, so as to form the insulation joint. The product must be applied
in the same way as a normal cementitious screed, by preparing the level strips,
which will then serve for spreading with a striker.
Float finishing must be carried out immediately after the product has been
spread or within 60 minutes. When this operation is carried out, the surface of
the screed can be splashed with water from a brush, so as to make the job
easier and faster, especially if a machine with a steel disc is used.
Do not smooth the surface to an excessive extent if parquet flooring must be
fixed to the screed, as this could lengthen the drying time.
Cleaning of Tools
Clean with water before hardening. Hardened product must be mechanically
removed.
