Description
Ardex MRF Moisture Resistant Finish
-10kg Bag
ARDEX MRF is a moisture-resistant, cement based smoothing compound designed to provide
a smooth, permanent finish to various internal substrates before installing waterproof membranes,
moisture barriers, and floorcoverings such as vinyl, carpet and ceramic tile.
ARDEX MRF allows installing most membranes and floorcoverings in as little as 30 minutes over
concrete, wood, ceramic and quarry tile, all without the need for priming or additives.
ARDEX MRF mixes with water to provide a smooth, creamy mortar for easy application.
SURFACE PREPARATION
Concrete floors must be structurally sound, clean and free of dirt, dust, oil, curing and sealing
compounds and any other surface contaminant which may act as a bond breaker. Where required,
mechanically clean the floor using recommended preparation methods such as shotblasting, diamond
grinding, shaving or other acceptable methods to a suitable surface. Acid etching, solvents or
sweeping compounds are not acceptable methods for preparation. Subfloor temperatures must be a
minimum of 10°C.
INSTALLATION
ARDEX MRF is easily applied to any prepared surface using a steel trowel. Apply sufficient
pressure to fill all defects and to feather the product into the subfloor surface. It is not necessary to
leave a minimum thickness on the substrate. Use the least amount possible to obtain the desired smoothness.
MOISTURE BARRIERS AND MEMBRANES
ARDEX MRF can be used to smooth irregularities from the concrete prior to the installation of moisture barriers and
waterproof membranes.
ARDEX MRF can be applied over ARDEX WPM 002, WPM 130, and WPM 155 Rapid Plus for resilient flooring and
tiling applications.
THICKNESS
ARDEX MRF can be applied from a true feather edge up to 6mm when applied on internal and external concrete, and
up to 3mm for internal timber applications.
POT LIFE
Approximately 15 minutes at 23°C. Pot life will be extended in cooler conditions and shortened in warmer
conditions. Mix only the amount that will be used immediately to avoid waste.
INSTALLATION OF FLOORING
As soon as the ARDEX MRF can be walked on without damaging the surface (from 30 minutes), floorcoverings
such as vinyl, carpet and ceramic tile can be installed.
COVERAGE
A 10kg unit will cover 9m2 at 1mm thickness. When skim coating over concrete, coverages up to 30m2
(at 0.3mm) can be achieved. Due to the unique formulation of ARDEX MRF and the varying thickness that this product
is applied, both coverage and drying time is difficult to specify and is an estimate only.
PAY ATTENTION TO THE FOLLOWING
• ARDEX MRF is not suitable for applications with full immersion. For example: swimming pools or ponds.
• Before any substrate preparation, installation or finishing methods relating to ARDEX product are
undertaken, please be aware of any potential risks and use appropriate PPE (personal protective equipment).
This may involve contacting substrate manufacturers for Safety Data Sheets.
