Description
UltraTile ProPave Bedding Mortar is a fibre modified cement binder which, when mixed with graded aggregates and water, can produce a rapid drying high strength bedding mortar ready to receive floor finishes such as Porcelain/natural stone tiles etc. UltraTile ProPave Bedding Mortar can be used to form falls within patios, driveways.
- For use with type 1 hardcore
- Fast track installation
- Fibre reinforced for added strength and durability
- Simply mix with sharp sand and water
- Dual-mix ratio for heavy or light trafficked areas
- Maintains porosity to facilitate drainage
- Approved for use with Porcelain and Natural Stone
- Depth: 30-100mm
- Internal and external use
- Part of the ProPave External Tiling System, which comprises the UltraTile ProPave Bedding Mortar, UltraTile ProPave Slurry Primer and UltraTile ProPave External Tile Grout.
UltraTile ProPave Bedding Mortar can accept light foot traffic after 12 hours. For highly trafficked areas such as drives and paths, curing will require a least 24 hours in good conditions.
Mixing:
UltraTile ProPave Bedding Mortar, aggregates and water can be mixed using mechanical mixers such as, concrete pan mixer, forced action mixer, screw mixer or pressurized screed pump. Where it is not possible to use a mechanical mixer and mixing by hand is required, it is recommended to thoroughly dry mix the UltraTile ProPave Bedding Mortar with the aggregates. Then adding water in small increments whilst mixing until a “damp earth” mix is achieved, typically 5 minutes. The mortar should hold together when formed into a ball.
Recommended Mix Design Ratios:
6:1 aggregate: (Domestic Patios) –
UltraTile Bedding ProPave Mortar binder: 285 kg/m³
0/8 mm Aggregate: 1715 kg/m³
Water: 100 kg/m³
4:1 aggregate: (Driveways and trafficked areas) –
UltraTile ProPave Bedding Mortar binder: 400 kg/m³
0/8 mm Aggregate: 1600 kg/m³
Water: 100 kg/m³
Note: Water addition may vary depending on moisture content of the aggregate being used.
Application:
All correctly prepared substrates are suitable for receiving an UltraTile Mortar. External tiling would be a sub-base of 100mm of type one compacted stone. This is made up of one 50mm layer of compacted stone, followed by a second 50mm layer, giving a compacted depth of 100mm. Once this has been achieved, a minimum thickness of 30mm bed of mortar and aggregate can be applied. For driveways and heavy trafficked areas we recommend an minimum bed depth of 60mm. Once bedding mortar has been laid, the reverse side of the porcelain or stone will require a coat of UltraTile ProPave Slurry Primer, this should then be positioned on to the bedding mortar ensuring wet on wet contact. For use with driveways and trafficked areas, we recommend a 4:1 ratio due to loading. For use on Domestic Patios, a 6:1 ratio is sufficient.
Precautions:
• Do NOT mix UltraTile ProPave Bedding Mortar with other cements or binders
• Do NOT dry mix with aggregate and leave
• Do NOT overwater
• Do NOT add water or re-agitate the mortar once setting has started
• Do NOT use fine sand – only use aggregate grading as in BS EN 13139 (0/8)
• USE as soon as it is mixed
Curing & Drying:
All curing and drying times are based on good site conditions i.e. an air temperature of 20°C, air humidity of 65% RH and good ventilation. Sites that are cold, humid or damp or in areas where the airflow is poor, will prolong drying and curing times, so allowances should be made accordingly. Applications to non-absorbent substrates and at thicker application depths will take longer to dry.
Coverage (4:1):
Consumption varies depending on thickness of the bedding mortar and the dosage of UltraTile ProPave Bedding Mortar. A 30mm layer will cover 1.65m² per 20kg bag.
Technical Data:
Density of mix, dependent on type of aggregate and mix ratio used (kg/m3): 2100 (approx.)
Pot life of mix (minutes): 60
Light foot traffic (hour): 12
