By  Last updated: 18th January 2013

CERAMACRETE GREY

DESCRIPTION
Ceramacrete is an economical thick or thin bed
cement based adhesive, specifically formulated to
bond a variety of tiles onto rigid substrates.
USES
• Ceramacrete can be used on both walls and floors
in interior and exterior applications.
• Ceramacrete 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 green marble tiles.
• When using Ceramacrete with translucent tiles the
colour of the adhesive must be considered.
• Ceramacrete can be used to lay tiles onto concrete,
cement renders/screeds, blockwork, rendered
brickwork and particular waterproofing membranes.
• Ceramacrete can be used to lay dense tiles such as
fully vitrified tiles when used in conjunction with
Davelastic.
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.
• 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
finish.
• 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 should 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
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 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.
MIXING
• Add Ceramacrete to a bucket of clean water mixing
constantly until a thick creamy consistency is
achieved.
• The mixing ratio is 20kg of Ceramacrete to
approximately 5lt of clean water.
• Allow the mixture to stand for 10 minutes, remix,
then use the adhesive.
APPLICATION
• 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
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.
• A 6mm x 6mm-notched trowel can be used to lay
mosaic tiles.
• 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
one time.
• Press tiles firmly into position before the adhesive
skins. Ensure 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 and the
adhesive coverage noted and the tile be relaid
accordingly.
• Once the tiles have been laid, they must not be
disturbed or trafficked upon for 24 hours.

GROUTING
• Grouting can be carried out 24 hours after the
completion of the tiling.
• Grouting can be carried out with one of the various
Davco grouts: Sanitized® Superfine White Grout for
internal wall joints 1-3mm; Sanitized® Colorgrout for
joints 1-6mm; and Slate and Quarry Grout for joints
6-12mm wide.
• To enhance the colour and increase water
resistance and flexibility of the grout, use 4 In 1
Grout Additive.
• Allow 24 hours after grouting before putting the area
into service.
PRECAUTIONS
• Do not apply Ceramacrete 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 Ceramacrete for tiling tiles with a water
absorption of 3% or less.
• Ceramacrete should 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 Ceramacrete over
substrates/situations not mentioned in these
instructions, contact your ParexDavco (Australia)
Pty Ltd state office
• Being cement based, Ceramacrete is alkali in
nature, which can cause dermatitis. Thus when
using Ceramacrete it is recommended that
applicators should wear PVC or similar gloves and
safety goggles.
• For a full MSDS on this product, contact your
ParexDavco (Australia) Pty Ltd state office.
COVERAGE
A 20kg bag of Ceramacrete will cover approximately
6m2 using a 6mm x 6mm-notched trowel.
CLEAN UP
• Remove any excess adhesive from the face of the
tiles with a damp cloth, while the adhesive is still
wet.
• Clean tools and equipment with water before the
adhesive dries.
PACKAGING
Ceramacrete is available in 5kg, 10kg and 20kg bags.
SHELF LIFE
Up to 12 months in unopened bags stored in an
