Morflex -premium grade flexible cement-based adhesive-Technical Data Sheet.
Morflex is a premium grade flexible, thick or thin bed cement-based adhesive. It is specially formulated to bond all types of tiles, with excellent flexural strength, onto a variety of substrates subject to vibration and thermal movement.
Morflex is unsuitable for:
bonding moisture sensitive green marble;
bonding to painted walls, MDF board, (timber and wax impregnated wood must be sheeted with fibre cement sheeting);
substrates subject to constant water immersion such as swimming pools.
All surfaces to be tiled must be flat and true, free from oil, dirt, grease or any other contaminants. Very porous surfaces should be primed with Plastinex (1 part Plastinex mixed with 4 parts water).
Concrete : New concrete must be allowed to cure for 6 weeks and should have a wood flat finish. When finished with a steel trowel, concrete must be acid etched, use Floor Prep.
Cement Render : Render to be left with a wood float finish and allowed to cure for 7 days.
Fibre Cement Sheets : Compressed fibre sheets should be primed with Plastinex and all joints to be taped with PVC duct tape and fixed according to manufacturers instructions.
Plasterboard : Must be fixed as per manufacturers instructions. Jointing compound should be primed with Plastinex.
Add Morflex to clean water at a ratio of 20 kg to 6 litres of water. Mix product to a smooth paste free from lumps by using a drill that has a speed lower than 300 rpm, or mix by hand. Slacken the adhesive and re-mix after 5-10 minutes.
Morflex has a pot life of approximately 3 hours at 20oC and 50% relative humidity.
Morflex has an open time of approximately 30 minutes, which can be shortened to just a few minutes by the action of sun, wind, high temperatures or highly absorbent surfaces. Tilers need to constantly check that the adhesive has not formed a surface skin and is still fresh to the touch.
Wetting or priming the substrate prior to tiling prolongs the open time of the adhesive. It is not advisable to wet the adhesive when it has formed a skin as water only increases the rate of cement hydration and will result in an anti adhesive film. Skinned adhesive must always be removed and disposed of.
Always install the tiles in accordance with AS 3958 1:1991 and ensure the backs of the tiles are free of dust. Spread Morflex evenly across one square metre at a time with a 6 x 6 x 6 notched trowel for walls or a 10 x 10 x 10 notched trowel for floors. The choice of trowel should be governed by the depth of the knobs, grooves or ridges on the back of the tile and the evenness of the substrate.
Lay the tiles with a fair pressure and at right angles to the notched pattern.
The final bed of adhesive should be between 2mm – 4mm. Wall tiles should have a finished joint width of 2mm – 4mm and floor files a finished joint width of 3mm – 6mm. Tiles can be adjusted for approximately 20 minutes after laying.
20 kgs of Morflex will cover approximately 7 – 8 square metres with a 10mm notched trowel for floors and/or 9 – 10 square metres with a 6mm notched trowel.
Morflex dries in approximately 6 hours and cured within 24 hours at 23oC and 50% relative humidity. It may require longer times to cure for denser tiles and substrates or at installation temperatures below 10oC.
Grouting may commence after approximately 6 hours (depending on variables such as sun, heat, wind, etc.)
Morflex can be stored in the original packaging in a dry elevated position for 12 months.
Morflex is available in 20kg paper sacks.
