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 membranes.
- 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.
FEATURES & BENEFITS
- 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 membranes.
- 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 materials.
- All building boards must be flat and firmly fixed according to the manufacturers 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 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 Davco Ultraprime.
- When tiling over old ceramic tiles or nonabsorbent/ contaminated surfaces prepare for tiling by using Davco Ultrabond. Refer to Ultrabonds data sheet for further details and suitability.
Movement joints should be provided as follows:
- Over movement joints in the background.
- At a junction between different background materials.
- At fixtures interrupting the tile surface eg columns.
- At internal vertical corners.
- Around the perimeter of the tiling system.
- 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 Econofix to a bucket of clean water mixing constantly until a thick creamy consistency is achieved.
- 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 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 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 cracking/powdering.
- 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.
