SpECtite WTA is designed to provide permanent
fixing for rigid materials, such as ceramic tiles, stone
cladding, slip bricks, glass mosaics, insulation and
acoustic boards.
· High bond strength
· Excellent waterproof characteristics
· Suitable for use onto a variety of substrates
Preparation
The substrate must be clean and dust free. All
contaminants such as friable material, grease
and oil should be completely removed.
Pre-soak the substrate but ensure that no standing
water remains.
Mixing
SpECtite WTA is a one-component cementitious
adhesive.4.75 to 6.0 litres of water are required for each 25kg
bag of SpECtite WTA depending on the consistency
required.
Generally, the lower water addition would be used for
vertical application and the higher water addition for
horizontal application.
Pour the measured volume
of water into an
appropriately sized plastic
or metal drum. The
powder should be added
to the water slowly whilst
mixing with a spiral paddle attached to a slow speed
electric drill. Mixing should continue for a minimum
of 5 minutes until a uniform, lump free consistency
is produced. Allow the product to stand for 15
minutes. Remix for 1 – 2 minutes prior to using.
Application
Apply SpECtite WTA at a depth of 3 – 6mm into a
working area not exceeding 1m².
For ceramic floor tiles, decorative stone cladding
and in wet conditions in general, solid-bed fixing is
recommended. In other situations, the adhesive may
be combed with a notched trowel prior to fixing.
Press the dry tiles into place using a twisting action
to ensure good contact with the adhesive. Tapping
with a rubber hammer ensures good contact with the
adhesive. Remove any excess adhesive from the
surface of the tiles with a damp cloth prior to the
material setting.
Allow the SpECtite WTA to cure for a minimum of
24 hours before attempting further grouting of joints
between ceramic wall/floor tiles. After fixing
ceramic floor tiles, no traffic should be allowed for
a minimum of 4 days @ 25°C.
SpECtite WTA is supplied in 25kg packs, each
pack produces approximately 15.5 litres of mixed
material, but will depend on the water addition used.
