Davco-Flexible CTA- white, acrylic based, flexible, premixed, interior, thin bed tile adhesive.

DESCRIPTION
Flexible CTA is a white, acrylic based, flexible, premixed,
interior, thin bed, wall tile adhesive.
USES
• Flexible CTA can only be used for interior wall
tiling installations.
• Flexible CTA can be used for thin bed fixing of
tiles directly onto fibrecement sheeting,
plasterboard and rendered walls.
• Flexible CTA can be used to fix most types of
porous ceramic and marble wall tiles, particularly
light coloured marbles, but with the exception of
green marble.
• When using Flexible CTA with translucent/
absorbent tiles, the colour of the adhesive must
be considered.
• Flexible CTA must not be used on floors or
over waterproofing membranes.


FEATURES AND BENEFITS
• Premixed – ready to use!
• No need for messy mixing making Flexible CTA
very easy to use.
• White in colour so there is no show through in the
grout joint.
• Perfect for bathroom, kitchens and laundry walls.
• Flexible.
SURFACE PREPARATION
• All surfaces must be structurally sound, dry,
clean and free from movement, oil, grease, wax,
curing compounds and any other loose or
contaminating materials.
• All building boards must be flat and firmly fixed
according to the manufacturer’s instructions and
relevant Australian Standard(s).
• Painted surfaces must be scabbled/abraded to
expose at least 80% of the original substrate.
• Newly rendered surfaces must be allowed to
cure for at least 7 days and have a wood float
finish.
• Old rendered surfaces must be thoroughly
cleaned prior to tiling and have a wood float
finish.
• Porous/dusty surfaces must initially be primed
using Davco Ultraprime.
Movement joints should be provided as follows:
1. Over movement joints in the background.
2. At a junction between different background
materials.
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
and adhesive bed to the background and be kept free
from dirt and adhesive droppings. Movement joints
should not be more than 6mm wide nor greater than
10mm wide. Movement joints that are 6mm wide can
be filled with Davco’s Sanitized® Colorcaulk. For
wider applications use Davco Davsil or polysulphide
and polyurethane type fillers.
APPLICATION
• Spread the adhesive onto the substrate using a
6mm x 6mm notched trowel for installation of
tiles up to 150mm x 150mm.
• For the installation of tiles larger than 150mm x
150mm use a 10mm x 10mm notched trowel.
• 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
substrate.
• For mosaic tiles, use a 6mm x 6mm-notched
trowel.
• A minimum final bed thickness of 2mm is
recommended, but the final bed thickness must
not exceed 4mm.
• Do not spread more than 0.5m2 of adhesive at
one time.
• 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 accordingly.
• Once the tiles have been laid, they must not be
disturbed for 24 hours at 20oC.

GROUTING
• 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 cracking/powdering.
• Allow 24 hours after grouting before putting the
area into service.
PRECAUTIONS
• Do not apply Flexible CTA in temperatures
above 40oC or below 5oC.
• 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 Flexible CTA over impervious
surfaces (i.e. waterproofing membranes) or to
bond low porosity tiles.
• Flexible CTA is not suitable for fixing tiles
externally or onto floors.
• Flexible CTA is not suitable is not suitable for the
tiling of areas where continual
dampness/immersion occurs, such as shower
recess bases, swimming pools, spas, etc.

substrates/situations not mentioned in these

Pty Ltd Materials state office.
