Davco – Econofix is a bright white, premium grade, thick or thin bed, fast setting, polymer modified

By  Last updated: 16th July 2012


Econofix is a bright white, premium grade, thick or thin
bed, fast setting, polymer modified, flexible, powdered
cement based adhesive, specifically formulated to bond
tiles onto a variety of substrates.
• Econofix can be used on both walls and floors, in
interior and exterior applications.
• Econofix is classified as a C1S1E adhesive system,
in accordance with AS4992.
• Econofix can be used to fix tiles onto concrete,
cement renders/screeds, blockwork, rendered
brickwork, plasterboard, fibre cement sheeting, old
ceramic tiles and particular waterproofing
• Econofix is suitable for tiling over timber floors,
provided that a fibre cement sheet tile underlay is
initially installed over the timber floor.
• Econofix is recommended for the thin or thick bed
fixing of all types of ceramic, mosaic, fully vitrified,
porcelain, terracotta, slate, quarry, granite and marble
tiles, particularly light coloured marbles, but with the
exception of green marble.
• When using Econofix with translucent tiles the colour
of the adhesive must be considered.
• Polymer modified – makes Econofix highly flexible
allowing it to be used over most building boards
without the use of an additive. This also allows the
product to be used over most waterproofing
• White in colour – Econofix is pure white allowing it to
be used with white marble and translucent tiles.
• Fast setting – Econofix dries in just 6 hours allowing
same day grouting even in low temperatures.
• Great coverage – a 20kg bag of Econofix will cover
approx. 12m2 (using a 6mm x 6mm notched trowel),
lowering the cost per square metre for Tilers.
• All surfaces must be structurally sound, dry, clean
and free from movement, oil, grease, wax, curing
compounds and any other loose or contaminating
• 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/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 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
Davco Ultraprime.
• When tiling over old ceramic tiles or nonabsorbent/
contaminated surfaces prepare for tiling by
using Davco Ultrabond. Refer to Ultrabond’s 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 materials.
3. At fixtures interrupting the tile surface eg 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
• Add Econofix to a bucket of clean water mixing
constantly until a thick creamy consistency is
• The mixing ratio is 20kg of Econofix to approximately
6 L of water.
• Allow the mixture to stand for 10 minutes, remix, and
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 to a
12mm x 12mm 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
• 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 6 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 Econofix 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.
• Econofix is not suitable for fixing tiles externally or
directly onto timber floors.
• When using Econofix externally or in wet areas
ensure adequate drainage exists, so that water does
not pond on the tile surface.
• Do not use Econofix for the tiling of areas where
continual water immersion occurs i.e. swimming
pools, spas, etc.
• For other uses or the use of Econofix over substrates/
situations not mentioned in these instructions, contact
your ParexDavco (Australia) Pty Ltd state office
• Being cement based, Econofix is alkali in nature,
which can cause dermatitis. Thus, when using
Econofix, it is recommended that applicators wear
PVC or similar gloves and safety goggles.
• For a full MSDS on this product, contact your
ParexDavco (Australia) Pty Ltd Materials state office.
A 20kg bag Econofix will cover approximately 12m2 using
a 6mm x 6mm-notched trowel.
• 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.
