APPLICATION:
Although Standards
do not ask for,
Tactiles to be countersunk’ into
the sub- floor; We suggest
this  for extra adhesion,
avoiding hazards  and for
better visual effect .Allowing the
base of the tile to be set into the
concrete, (tile thickness is 2 mm) thus
allowing only the studs  to be above
the  surface level.
We also suggest the
application of a waterproof sealant on
the concrete prior to application of the
Tactile indicators.

Adhesion
Under some  critical conditions an Adhesion Test should be performed.
Test is to verify if there is a good bond to the sub- floor and the back of the PVC  tile .
This test should last at least 72 hours. After
this time the removal of other
flooring should be hard, and the
adhesive should remain bonded to both
the sub- floor and the PVC Tactile.
The concrete surface should be dry and
clean. The surface should be level,
without surface imperfections which
would appear through the PVC  Tile.
The surface should be flat within 4 mm over 2mtrs  The surface should look like 360 grit  sandpaper.
Concrete slabs are often treated with
Curing Compounds, Sealers and Hardeners. These treatments must be removed from the
surface by bead blasting or terrazzo grinding.
All existing paints, grease, old adhesive and oil must be removed from the slab.

FLOOR PREPERATION
Cracks, depressions and rough surfaces should be filled with a top quality levelling compound  mixture with at least 25mpa finish
The concrete surface should be dry and
clean. The surface should be level,
without surface imperfections which
would appear through the PVC  Tile.

EXISTING FLOOR SUGGESTION
Old floor coverings should be removed completely. In cases where Tacalert  flooring will be
installed over Terrazzo, Ceramic or  tile, the old tiles or terrazzo must be abraded
thoroughly to remove glaze and waxes. Any loose tiles must be removed, level grout lines and
other empty spaces with an approved commercial floor fill material. Application of
any floor fill material should be done at least 24 hours prior to the start of the actual installation
work. The area should be sanded before installation.
