Substrate Preparation & Expansion Joints

All substrates to be tiled must be flat and true, free from oil, dirt, grease or any other contaminants. Very porous substrates should be primed with Morgan Universal Primer. Incorporate expansion joints in accordance with AS 3958.1 2007.

• Concrete: New concrete must be allowed to cure for 6 weeks and should have a wood float finish. Use Floor Prep to acid etch an adhesive key into concrete finished with a steel float.
• Cement Render : Render to be left with a wood float finish and allowed to cure for 7 days.
• Fiber Cement Sheets : Fiber cement sheets must be primed with Morgan Universal Primer and all joints must be taped with PVC duct tape and fixed according to the manufacturer’s instructions.
• Plasterboard : Plasterboard must be fixed as per manufacturer’s instructions. Jointing compound must be primed with Morgan Universal Primer.
• Painted Substrates: Oil based paints must be in good condition with all flaky paint removed. Surfaces must be washed with a commercial cleaner such as Sugar Soap. Acrylic based paint surfaces are to be treated in the same manner as oil based paint surfaces. PVA based paint surfaces must be scabbled to expose at least 80% of the original substrate.
• Tilt Up Slabs: Silicon or diesel release agents must be thoroughly removed prior to tiling. Liaise with the manufacturer to identify the release agent and removal strategy. Gyprock sheeting or sandblasting is recommended.
• Tile Over Tile: High gloss tiles should be mechanically roughended to expose 80% of the biscuit. Tiles should be thoroughly cleaned with a commercial cleaner such as Sugar Soap.
• Metal Substrates: Thoroughly clean & degrease. Epoxy primers are recommended to guarantee a bond.

Open Time

Powerflex has an open time of approximately 10 minutes, which can be shortened to just a few minutes by the action of sun, wind, high temperatures or highly absorbent surfaces. Dampening or priming the substrate prior to tiling prolongs the open time of the adhesive. Tilers need to constantly check that the adhesive has not formed a surface skin and is still fresh to touch. Adhesive with a surface skin must be always removed and discarded.

Mixing

Add Powerflex to clean water at a ratio of 20kg to 5 liters of water. Mix the adhesive 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 minutes.

Application, Tools & Adjustability Time

Always install the tiles in accordance with AS 3958 and ensure the backs of the tiles are free of dust. Spread Powerflex evenly across one square meter at a time with a 6mm notched trowel for walls and a 10mm notched trowel for floors. The choice of trowel should be governed by the depth of the knobs, grooves or ridges on the back of each tile and the evenness of the substrate. Lay the tiles with a fair pressure and at right angles to the adhesive notched pattern. The final bed of adhesive should be between 2mm and 4mm. Wall tiles should have a finished joint width of 2mm - 4mm and floor tiles should have a finished joint width of 3mm - 6mm. Tiles can be adjusted for approximately 5 minutes after laying.

Coverage

20kgs of Powerflex will cover approximately 12 square meters with a 6mm notched trowel for walls and approximately 10 square meters with a 10mm notched trowel for floors.

Cure Time

Powerflex cures in approximately 24 hours at 23°C and 50% relative humidity. High density substrates or tiles and temperatures during installation below 10°C will significantly increase the cure time.

Clean Up

Remove excess Powerflex from the grout joints after 10 minutes and clean the tiles with a damp cloth or sponge. Tools and hands can be cleaned with water while the adhesive is still wet.

Joint Grouting

Depending on environmental conditions, commence grouting after approximately 3 hours. Use Regular Grout for grout joints between 3mm to 6mm or Architectural Superior Grout for grout joints between 0.5mm to 3mm. Morgan Slate & Quarry Grout should be used for joint sizes between 6mm to 20mm. Use Aquapoxy, a three component acid resistant epoxy grout, if the joints are required to have a good chemical resistance. The ideal grout joint is 3mm. Grout Add may also be mixed with Regular Grout to impart extra flexibility, reduce porosity and increase water resistance.

Do not use excessive amounts of water during mixing or initial cleaning as this will cause irregular color finishes and also weaken the grout. Do not mix the grout with an electric drill above 300 rpm as this can entrap air into the mix causing grout to dry soft and powdery or with unsightly pin holes in the surface. All grouts should be damp cured for 48 hours. Refer to the australian standard as 3958 part 1 section 5.7.3.

Specification Clause

The wall & floor adhesive shall be Morgan Powerflex - a high performance tile adhesive complying with all relevant Australian & International technical standards.
