Supplier Code:

• 20Kg Bag – MPL25

 

Area of Use:

• MJS LEVEL-IT L25 is designed for levelling internal dry concrete slabs.

 

Surface Preparation:

• Concrete floors must be solid, clean and free of dirt, dust, wax,
  grease, asphalt, latex compounds, curing and sealing compounds and any other
  surface contaminant.
• Mechanically prepare the floor using recommended preparation methods
  such as shotblasting, scarifying, diamond grinding, shaving or other suitable
  methods to provide a roughened, clean, sound, solid and open porous surface.
• Acid etching is not an acceptable method of cleaning the subfloor.
• Do not use solvents or sweeping compounds
• Subfloors must be dry (AS 1884) and properly primed for successful
  installation.
• Subfloor temperatures must be a minimum of 10°C.

 

Priming:

• Use ARDEX P51 over standard concrete floors prior to the installation
  of MJS Maxprep levelling compounds.
• Mix 1 part ARDEX P51 with 2 parts water and apply evenly using a push
  broom.
• Do not use paint rollers, mops, or spray equipment.
• Do not leave any bare spots.
• Brush off all puddles of excess primer.
• Allow to dry to a thin, clear film (min. 3 hours, max. 24 hours).
• Very absorbent concrete may require two applications of primer to avoid
  pinholes and bubbling in the levelling compound.
• In such cases, make the initial coat 1 part ARDEX P51 diluted with 3
  parts water.
• Allow to dry and install a second coat of 1 part ARDEX P51
  diluted with 1 part water.
• Allow to dry to a thin, clear film (min. 3 hours, max. 24 hours).

 

Mixing Ratio:

• 4.5 litres of water to 20kg of MJS
  LEVEL-IT L25 powder.

 

Mixing:

• MJS floor levelling products react and harden very quickly when
  mixed with water.
• Thorough mixing in the shortest time is essential to ensure the powder
  and water are evenly dispersed throughout the mix to obtain a lump-free mortar.
• Always mix the powder into the water.
• Concrete mixers and hand mixing are not suitable methods.
• The most efficient method of mixing is by using a mixing paddle
  and a heavy-duty electric drill (650 rpm).
• Mix for 2 to 3 minutes for a 20kg using an electric drill or
  paddle.

 

Application:

• Pour the mixed MJS LEVEL-IT L25 onto the prepared subfloor.
• Wear football boots with rubber or nylon studs to avoid leaving
  unnecessary marks in the liquid MJS LEVEL-IT 25.
• Do not rework MJS LEVEL-IT L25 after 10 minutes.
• For ease and efficiency of application MJS LEVEL-IT L25
  can be pumped using a suitable Automatic Mixing Pump.
• Follow the instructions as set by the pump manufacturer.

 

Thickness:

• MJS LEVEL-IT L25 can be applied from 2.5mm to 25mm in one
  application.

 

Bulk Fill Application:

• MJS LEVEL-IT L25 can be mixed with well washed and dried 2-5mm
  aggregate for applications of 10mm to 40mm.
• A maximum ratio by weight of aggregate to MJS LEVEL-IT L25 shall be
  1:1.
• First mix MJS LEVEL-IT L25 powder with water, continue mixing while
  adding aggregate gradually until the aggregate is thoroughly and evenly mixed.
• Note: Adding aggregate will modify the flow and
  consequently the smoothing and self levelling properties of MJS LEVEL-IT L25.

 

Coverage:

• A 20kg bag will cover approximately 4m² at 3mm thickness.

 

Dry Hardening:

• MJS LEVEL-IT L25 with a 5mm layer will harden after approximately
  3 hours at 23°C and can be walked on after this time.
• Hardening and drying time will be extended in cooler climates, and
  shortened in warmer climates.
• Thicker layers will also extend drying times.
• MJS LEVEL-IT L25 is ready for conventionally laid carpet, floating
  floors and vinyl after 24 hours. Tiling can commence once walkable.
