Mapei Fix & Grout Concrete & Timber Floors extended informationFor use on internal floors only. Suitable for use in domestic kitchens and bathrooms. For the installation of ceramic and porcelain tiles. For fixing onto sand: cement screed, concrete, securely fixed tongue and groove P5 grade chipboard (ceramic tiles only) floor boards, 15 mm exterior grade plywood overlay and tile backer boards.Some application examplesMapei Fix & Grout Concrete & Timber Floors is used for bonding and grouting ceramic and porcelain tiles.Please note: If used with a porcelain tile the drying times will be greatly increased.Recommended for normal household installations kitchen, bathrooms, conservatories and other household areas.Ensure that all substrates are fully cured and dry before commencing tiling.If fixing to a new timber substrate, the timber must be allowed to acclimatise to the room atmospheric climate. Dusty surfaces may be primed with Mapei Eco Prim T Plus diluted 1:2 with water, or Primer G diluted 1:1 with water. Allow to fully dry before tiling.Mapei Fix & Grout Concrete & Timber Floors technical characteristicsMapei Fix & Grout Concrete & Timber Floors is a flexible aqueous dispersion based adhesive of D2E classification. Based on fine-graded mineral fillers, additives and mould resistant Bio Block Technology..It has mould-resistant BioBlock (R symbol) Technology.It is easy to trowel to most timber and concrete surfaces.It sets as the water it contains evaporates forming an extremely strong bond between tile and substrate. It is resistant to the normal vibration found in domestic dwellings.It although flexible will only perform if the substrate has been rigidly fixed following British Standard installation guidelines. When used as a grout it is water resistant for application on floors in kitchens and most domestic bathrooms.It hardens without shrinking in joints up to 6 mm. Due to the product being non-thixotropic, is not suitable for walls.LimitationsIs not suitable for heavy duty wet areas or in areas of constant water immersion, e.g. communal showers, power showers or swimming pools.Can be used on shower floors provided that the MAPEI Shower Waterproofing Kit has been installed and the tile is absorbent.For use on interior floors only.Do not grout until the adhesive has dried. This is usually within 24-48 hrs depending on the tile, substrate type and ambient temperature. When using porcelain tiles drying times will be greatly extended.Do not use on metallic surfaces.Only use Fix & Grout Concrete & Timber Floors on moisture resistant grade timber which is fixed rigidly in place using screws.Do not use for bonding non-absorbent materials on non-absorbent surfaces i.e. porcelain tiles must be fixed to an absorbent substrate. At least one of the surfaces must be absorbent.Do not exceed a tile size of 300 × 300 mm.Do not exceed bed depth of 3 mm.Mapei Fix & Grout Concrete & Timber Floors product identityConsistency:soft pasteColour:greyDensity (g/cmÑ):1.60Dry solids content (%):80 ÷ 0.5Brookfield Viscosity (mPa•s):650,000 ÷ 50,000APPLICATION DATA (at 23°C - 50% R.H.)Application temperature range:from 5°C to 35°COpen time (according to EN 1346):40 minutesAdjustability time:50 minutesGrouting:after 24 hoursReady for use:after 7-14 days depending on the absorption of the surfaceFinal PerformancesShear adhesion strength according to EN 1324 (N/mmÇ): a) initial shear adhesion strength: b) shear adhesion strength after heat ageing: exceeds minimum requirements of BS EN 12004 type D2E c) shear adhesion strength after water immersion: d) shear adhesion strength after elevated temperature: 1 1 0.5 0.1Resistance to moisture:goodResistance to ageing:excellentResistance to solvents and oils:poorResistance to acids and alkalis:poorTemperature resistance in service:from -30°C to 90°CDeformability:highly deformablePreparation of the substrateEnsure the substrate is flat, firm, dry and free from contamination such as paint, polishes, old adhesive residues, grease, aitance and dust. Remove these residues by mechanical means i.e. abrasion. If fixing to old concrete or sand; cement screeds, prime with Eco Prim T Plus diluted 1:2 with water, or Primer G diluted 1:1 with water. New concrete should be left to cure for a minimum of 6 weeks, sand:cement screeds allowed to cure for a minimum of 3 weeks. Calcium sulphate screeds must be fully dry. They must be mechanically abraded to remove all laitance, remove all dust created and prime with Mapei Eco Prim T Plus diluted 1:2 with water, or Mapei Primer G applied neat. Refer to manufacturer’s recommendation for drying times. Once priming has taken place tiling can usually commence after 1-2 hours.Applying the productStir the product thoroughly prior to application. Apply the adhesive using a suitable notched trowel to ensure a solid continuous layer of adhesive supports the tiled finish. Spread the adhesive over no more than 1 m? before applying tiles. The open time of the adhesive is approx. 40 minutes depending on the porosity and type of substrate and the temperature of the room. Apply the selected tile in to the fresh adhesive bed using a twisting/sliding motion, ensuring 100% coverage is achieved. Check by lifting a tile to see this coverage is maintained. Apply an additional layer of adhesive to the rear of larger tiles, ensuring the bed depth is at a maximum thickness of 3 mm. Clean any residues from the tile face immediately. If a matt finish or rough textured tile is used please be aware the Mapei Fix & Grout Concrete & Timber Floors will dry in the pores of the tile. It is essential to clean off immediately.Grouting and Movement JointsDo not grout until the adhesive has dried. This is usually within 24-48 hrs depending on the tile and the substrate. Using a MAPEI grout squeegee/rubber float, spread the Mapei Fix & Grout Concrete & Timber Floors firmly into the tile joints ensuring a full joint is achieved. Wipe off all excess grout immediately using a lightly dampened sponge or a white coloured MAPEI emulsifying pad. Do not over wash the grout during the cleaning off process as this may introduce air bubbles or, pin holes into the grout surface or colour inconsistency.Movement joints should be filled with Mapesil AC.Set to Light Foot TrafficFloors are able to take light foot traffic after a minimum of 24-48 hours, provided that the product had set hard. Lower temperatures, bonding porcelain tiles and/or substrates that have low or no porosity will extend the setting time.Ready For UseAreas can be put into full service after 7-14 days depending on the absorption of the substrate.CleaningImmediately remove residues of adhesive or grout from the tiles using a damp sponge.Do not over wash the grout joints. Remove hardened residues with a white emulsifying pad.Mapei Fix & Grout Concrete & Timber Floors D2E ConsumptionAs an adhesive using a standard trowel – coverage approx 3-5 m2 per 15 kg bucket. When grouting a tile 300x300x10 mm with a 5 mm Joint, the coverage will be approx 0.5 kg m?.Please note: The above figures are separate calculations and are not valid for the product used as both adhesive and grout i.e. the quantity used for grouting will be additional to the quantity used for tiling.Packaging15Kg bucketsStorageStore off the ground in a cool dry environment, free from frost and direct sunlight. Protect from sunlight. Mapei Fix & Grout Concrete & Timber Floors has a shelf life of 12 months. Once opened it is recommended to apply a layer of polythene or similar on top of the product in the tub if it will not all be used at once. This will help maintain the shelf life of the product, however it is recommended to use the product soon after opening.
