Roberts UltraFlo Premium Floor Leveller

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.
1. If the water absorbs into the substrate in less than ONE (1) minute,
   the substrate is POROUS.
2. 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.
