TTB OFF WHITE
TTB Off White is an economical off-white thick or thin
bed cement based adhesive specifically formulated
to bond a variety of tiles onto rigid substrates.
TTB Off White can be used on both walls and floors
in interior and exterior applications.
TTB Off White can be used to fix tiles onto concrete
cement renders/screeds blockwork rendered
brickwork and particular waterproofing membranes.
TTB Off White is recommended for the thin or thick
bed fixing of ceramic and most monocottura tiles as
well as mosaics terracotta slate quarry granite
and marble with the exception of light coloured or
When using TTB Off White with
translucent/absorbent tiles the colour of the
adhesive must be considered to avoid
TTB Off White can be used to fix dense tiles such
as fully vitrified tiles when used in conjunction with
TTB Off White when combined with neat Davelastic
can be used to fix tiles over tiles or fix tiles in
immersed situations i.e. swimming pools spas etc.
Initially contact your ParexDavco (Australia) Pty Ltd
state office for further details.
All surfaces must be structurally sound dry clean
and free from movement oil grease wax curing
compounds and any other loose or contaminating
Painted surfaces must be scabbled/abraded to
expose at least 80% of the original substrate.
Newly rendered/screeded surfaces must be allowed
to cure for at least 7 days and have a wood float
Old rendered/screeded surfaces must be thoroughly
cleaned prior to tiling and have a wood float finish.
New concrete must be allowed to cure for 6 weeks
and have a wood float finish.
Steel trowel finished concrete must be acid etched
or mechanically abraded prior to tiling.
Old concrete surfaces must be thoroughly cleaned
prior to tiling.
Make sure all release agents are removed from
concrete surfaces especially on tilt-up slabs.
Porous/dusty surfaces must initially be primed using
Certain non-absorbent/contaminated surfaces can
easily be prepared for tiling via the use of Davco
Ultrabond. Refer to Ultrabonds data sheet for
further details and suitability.
Movement joints should be provided as follows:
1. Over movement joints in the background.
2. At a junction between different background
3. At fixtures interrupting the tile surface e.g. columns.
4. At internal vertical corners.
5. Around the perimeter of the tiling system.
6. At a maximum of 5 metre intervals in a grid pattern.
Note: Movement joints should go right through the tile
adhesive bed to the background and be kept free from
dirt and adhesive droppings. Movement joints must
not be less than 6mm nor greater than 10mm wide.
All movement joints that are 6mm wide can be filled
with Davco Sanitized® Colorcaulk. For wider
applications use Davco Davsil or polysulphide and
polyurethane type fillers.
Add TTB Off White to a bucket of clean water
mixing constantly until a thick creamy consistency is
The mixing ratio is 20kg of TTB Off White to
approximately 5 litres of clean water.
Allow the mixture to stand for 10 minutes remix
then use the adhesive.
Spread the adhesive onto the substrate using a
6mm x 6mm notched trowel for the installation of
wall tiles up to 150mm x 150mm.
For the installation of floor tiles or wall tiles larger
than 150mm x 150mm use a 10mm x 10mm
Tiles with lugs grooves or an uneven back must
initially be butter coated with the adhesive in
addition to the adhesive being trowelled onto the
A 6mm x 6mm-notched trowel can be used to lay
For wall tiling a minimum final bed thickness of 2mm
is recommended whilst for floor tiling a minimum
final bed thickness of 3mm is recommended.
Do not spread more than 1m2 of adhesive at any
TTB OFF WHITE
Press tiles firmly into position before the adhesive
skins ensuring that all the tiles are well bedded and
that no voids occur under the tiles.
Occasionally in order to ensure that full coverage is
being maintained a tile should be removed the
adhesive coverage noted and the tile be relaid
Once the tiles have been laid they must not be
disturbed or trafficked upon for 24 hours at 20oC.
Grouting can be carried out 24 hours after the
completion of tiling.
Use the Davco grout that best suits the tiling
installation. Refer to the Davco Adhesive and
Grout Selection Guide for further information.
To enhance colour increase water resistance and
flexibility of the grout use Davco Grout Additive.
This is particularly recommended when grouting
over timber or fibre cement sheeted floors to
minimise the likelihood of the grout
Allow 24 hours after grouting before putting the
area into service.
Do not apply TTB Off White in temperatures above
400C or below 50C.
Do not allow the adhesive to skin prior to laying the
tiles. If the adhesive skins remove and dispose of
it then re-apply fresh adhesive.
Do not use TTB Off White for fixing tiles with a water
absorption of 3% or less.
TTB Off White must be used with neat Davelastic
when tiling areas where continual immersion occurs
i.e. swimming pools spas etc.
For other uses or the use of TTB Off White over
substrates/ situations not mentioned in these
instructions contact your ParexDavco (Australia)
