Description
Roberts EcoFlo Rapid Drying Self-Leveller
– 1mm to 30mm Build Thickness
– Available in 20kg Bags
Roberts EcoFlo is rapid drying self levelling compound with excellent flow
properties formulated for self- levelling differences from 1 to 30 mm in thickness
on new or existing internal concrete substrates. It develops a smooth and even
surface with high levels of mechanical resistance, ensuring the subsequent
installation of floor coverings such as carpets, resilient coverings, linoleum,
timber flooring, and tiled floor finishes.
FEATURES & BENEFITS:
- Excellent Flow
- Thickness 3mm – 100mm
- Pump application
TECHNICAL CHARACTERISTICS:
- Roberts EcoFlo is a grey powder consisting of a unique rapid setting
and hydrating cement, blended with graded silica sand, resins and special
additives. - Roberts EcoFlo may be applied using an automatic pressure pump.
- Roberts EcoFlo can be spread in thicknesses up to 30mm per coat without
shrinkage, cracking, or crazing develops very high compressive and flexural
strength and resistance to indentation and abrasion. - Flooring installation can begin approximately 12 hours after the
application of Roberts EcoFlo. - Once dry is suitable for applying vinyl, carpets, linoleum, floating
floors, and tile floor finish.
RECOMMENDED USE:
- Levelling new and existing concrete substrates, terrazzo, ceramic,
natural stone, and magnesite floors. - Levelling over underfloor heating systems.
- Roberts EcoFlo is pumpable
CLASSIFICATION ACCORDING TO EN 13813:
- The material properties of Roberts EcoFlo are classified as
CT-C30-F6
SURFACE PREPARATION:
- Substrates must be dry, sound, clean, and per the relevant National,
State, and Local Building codes, including applicable Australian Standards. - Substrates must also be free of wax, grease, oil, polishes, old
adhesive, curing compounds, high levels of moisture, and any other surface
contaminants that may affect adhesion. - If mechanical preparation is required, prepare the floor using
recommended methods such as shot blasting and diamond grinding to provide a
roughened, clean, sound, and open porous surface. - Thoroughly vacuum loose material and dust.
- The minimum subfloor temperature before commencing installation should
be 10ºC. - Do not use solvents or acid etching to clean the subfloor.
- For resilient installations, relative humidity and pH readings must be
carried out on the concrete substrate as outlined in the Australian Standard 1884-
2021. - For substrates that display high moisture levels, RLA recommends that
RLA MOISTURE SEAL is applied before the Installation of Roberts EcoFlo. - If temperatures are less than 5°C or higher than 35ºC, please contact
the RLA Technical department for further details.
PRIMING:
- Prime substrates with ROBERTS R48 UNIVERSAL PRIMER
Porous Substrates:
- Mix one (1) part Universal Primer with two (2) parts of clean water.
- Apply an even film using a roller or brush, ensuring the entire area is
covered and allowed to cure. - Highly absorbent or porous surfaces may require a second coat of
ROBERTS R48 UNIVERSAL PRIMER to avoid pinholes.
Non-Porous Substrates:
- Substrates such as ceramic tiles have no coatings or sealing compounds
on the surface before applying primer. - Coatings, curing, and sealing compounds must be mechanically removed
from concrete substrates. - Apply an even layer of ROBERTS R48 UNIVERSAL PRIMER neat (undiluted to
non-porous substrates). - Allow the primer to dry (approx. 2 hours @ 23°C).
- Once Primer is a tack-free transparent film, products can be applied
over the primer
Examples of Non-Porous Substrates:
- Burnished Concrete, Ceramic Tiles, Liquid Waterproofing membranes.
- NOTE 1: For extremely non-porous substrates, it is recommended
that a light grind or sand be conducted to enhance adhesion. - Determining whether a substrate is POROUS or NON-POROUS, pour water
from a bottle or a dropper forming a puddle onto the substrate surface, the size of
a 10-cent coin. - If the water absorbs into the substrate in less than ONE (1) minute,
the substrate is POROUS. - If the puddle remains, the substrate is NON-POROUS.
- NOTE 2: ATSM F3191-16 Standard Practice for Field Determination
of Substrate Water Absorption (Porosity) for Substrates
MIXING RATIO:
- Mix one 20kg bag with 4.6-4.8 litres of clean water.
- Mix Roberts EcoFlo levelling compound with a drill and suitable mixing
paddle. - Slowly add the powder to the water while mixing at a low speed.
- It is essential to ensure the powder and water are mixed evenly for
approximately three (3) minutes and that the water has dispersed to obtain a lump-
free mix. - Do not overwater, as this will promote bleeding and separation
with a reduction in bond and tensile strength. - DO NOT MIX BY HAND & DO NOT ADD EXCESS WATER
APPLICATION:
- Apply in one coat from 1mm to 30mm.
- Apply the mixed compound to the primed substrate using a gauge rake,
stand-up spreader at the required height adjustment, or trowel on a slight incline
to obtain the necessary thickness. - Installations can also be pumped using an appropriate mixing pump.
- The mixed quantity must be used within 15 minutes at a temperature of
23°C. - Due to its self-levelling properties, Roberts EcoFlo will quickly
develop a smooth finish and even surface.
SETTING TIMES:
- When applied will harden after 2-3 hours at 23°C and can be walked on
after this time. - The levelling coat will be ready to receive floor coverings fixed with
adhesives after 12 hours at 23°C (time may vary depending on temperature and
humidity).
COVERAGE:
- 12m² per 20kg bag @ 1mm thickness
- 4m² per 20kg bag @ 3mm thickness
CLEAN UP:
- Clean tools immediately after use with water.
- Do not pour mixed Roberts EcoFlo down drains, which will cause
blockages. - Pour any leftover mix into an empty bag of Roberts EcoFlo and discard
once the product has set hard.
SHELF LIFE/STORAGE:
- 12 months when stored in original unopened packaging.
- Stored in a dry area off the ground.
PACKAGING:
- 20kg bags
NOTES AND PRECAUTIONS:
- Do not allow Roberts EcoFlo to come into contact with water during or
after the curing process. - Do not apply to substrates subject to rising dampness.
- Drying times are extended when applied in cold ambient temperatures.
- Not Suitable for particle board or strip timber flooring.
- Do not apply over expansion joints, as reflective cracking may occur.
- INTERNAL USE ONLY
COMPATIBILITY:
- Roberts EcoFlo is compatible with the ROBERTS range of moisture
seals, primers, carpet, resilient, and timber adhesives.
