Description

Roberts UltraFlo Premium Floor Leveller
– 1mm to 30mm Build Thickness
– Available in 20kg Bags

Roberts UltraFlo 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 rapidly develops smooth and
even surfaces with high levels of mechanical resistance, ensuring the subsequent
installation of floor coverings.

FEATURES & BENEFITS:

Excellent Flow.
Thickness 1mm – 30mm.
Rapid Drying.
Floor Coverings 12 hours after application.
Pump application.
High mechanical performance.

RECOMMENDED USE:

Once dry, it is suitable for applying vinyl, carpets, linoleum,
floating floors, timber flooring, and tile floor finishes.
It is ready to accept most floor coverings after approximately 12 hours
and allows for quick and reliable installation.
Installations of Timber floorcoverings can take place 24 hours after
application.
When installing hardwood timber flooring onto a concrete substrate, the
levelling must be no less than 3 mm.
Roberts UltraFlo Leveller is pumpable for internal applications and
suitable for underfloor and heating systems.

CLASSIFICATION ACCORDING TO EN 13813:

The material properties of Roberts UltraFlo 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 surtace.
Thoroughly vacuum loose material and dust.
The minimum subfloor temperature before commencing installation should
be 10°C.
Do not use solvents or acid etching to clean the subtloor.
For resilient installations, relative humidity and pH readings must be
carried out on the concrete substrate by Australian Standard 1884-2021.
For substrates that display high moisture levels, RLA recommends that
RLA MOISTURE SEAL is applied before the Installation of Roberts UltraFlo.
If temperatures are less than 50C or higher than 350C, don’t hesitate
to contact the RLA Technical department for further details.

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.
Larger 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 UltraFlo will quickly
develop a smooth finish and even surface.

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 5.0 – 5.2 litres of clean water.
Mix Roberts UltraFlo 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.

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 20 kg bag at 1mm thick, 4m2 at 3mm thick

CLEAN UP:

Clean tools immediately after use with water.
Do not pour mixed Roberts UltraFlo down drains, which will cause
blockages.
Pour any leftover mix into an empty bag of Roberts UltraFlo 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:

Drying times can be extended when applied in cold ambient
temperatures.
Do not allow it to come in contact with water during or after the
curing process.
Do not apply on substrates with rising dampness.
Internal use only.
Not Suitable for particle board floors.
Do not apply over expansion joints, as reflective cracking may occur.

COMPATIBILITY:

Roberts UltraFlo is compatible with the ROBERTS range of moisture
seals, primers, carpet, resilient, and timber adhesives.
