PRECAUTIONS
Professional Tilers Blend is unsuitable for: - bonding moisture sensitive green marble;
- bonding to MDF board or timber & wax impregnated wood ;
- bonding to substrates subject to constant water immersion such as swimming pools.
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 Plastinex (1 part Plastinex mixed with 4 parts water). 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.
MIXING & POT LIFE
Add Professional Tilers Blend to clean water at a ratio of 25kg to 6 litres 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. Professional Tilers Blend has a pot life of approximately 3 hours at 23°C and 50% relative humidity.
OPEN TIME
Professional Tilers Blend 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. 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.
APPLICATION, TOOLS AND ADJUSTABILITY TIME
Always install the tiles in accordance with AS 3958 1:1991 and ensure the backs of the tiles are free of dust. Spread Professional Tilers Blend evenly across one square metre 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 10 minutes after laying.
COVERAGE
25kgs of Professional Tilers Blend will cover approximately 8 square metres with a 6mm notched trowel for walls and approximately 6 square metres with a 10mm notched trowel for floors.
CURE TIME
Professional Tilers Blend 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 Professional Tilers Blend from the grout joints after 30 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 12 hours. Use Regular or Superior Grout for grout joints between 3mm to 6mm. Morgan Slate & Quarry Grout should be used for joint sizes between 6mm to 20mm. Use Aquapoxy, a three component anti-acid epoxy grout, if the joints are required to have a good chemical resistance. Grout Add may also be mixed with Regular Grout to impart extra flexibility, reduce porosity and increase water resistance.
JOINT GROUTING PRECAUTIONS
DO NOT use excessive amounts of water during mixing or initial cleaning as this will cause irregular colour 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.
SHELF LIFE
Twelve months if stored in a dry & elevated position in the original factory sealed packaging.
