Mapei Planex HR Maxi Self Leveller

Description

Mapei Planex HR Maxi Self Leveller
– 20kg bags

 

Rapid-drying, moisture resistant, self-levelling smoothing compound for
layers 3 to 40 mm thick.

 

WHERE TO USE:

• Planex HR Maxi is suitable for internal and external applications and
  is used to level off new and existing substrates and remove differences in
  thickness from 3 to 40 mm to make them suitable for laying all types of floor
  coverings, including resilient, textile and ceramic tiling.
• Planex HR Maxi is particularly recommended for use in areas where high
  resistance to static and dynamic loads is required.
• Thanks to its special formulation and good resistance to moisture,
  Planex HR Maxi may also be used for external applications or on substrates that are
  not completely dry or which have a high level of residual moisture.

 

APPLICATION EXAMPLES:

• Smoothing over concrete floors and cementitious screeds made from
  Mapecem, Mapecem Pronto or Topcem Pronto.
• Smoothing over heated floors.
• Smoothing over existing concrete, terrazzo, ceramic, natural stone and
  magnesite floors.
• Smoothing over concrete and cementitious-based substrates before
  bonding non-welded resilient floor tiles with reactive adhesive in areas that need
  to be washed or rinsed frequently.
• Smoothing over concrete substrates with rising damp before placing PVC
  isolating sheets on which resilient flooring for sporting and non-sporting use is
  to be installed.

 

TECHNICAL CHARACTERISTICS:

• Planex HR Maxi is a grey coloured powder made from special rapid-
  hydrating and rapid-setting cement, selected silica sand, resins and special
  admixtures according to a formulation developed in the MAPEI research laboratories.
• When Planex HR Maxi is mixed with water, it forms a rapid-drying, free-
  flowing, self-levelling mortar with good workability that adheres very strongly to
  the substrate.
• Planex HR Maxi is applied in layers from 3 to 40 mm thick per layer. It
  does not shrink or crack and reaches a high level of compressive and flexural
  strength and resistance to indentation and abrasion.
• Planex HR Maxi dries very quickly: for example, ceramic may be bonded
  after 3 hours and resilient and textile floor covering may be bonded after 24-72
  hours, depending on the smoothing layer thickness.

 

RECOMMENDATIONS:

• Do not add water to the mix once it starts to set.
• Do not add lime, cement or gypsum to the mix.
• Do not use Planex HR Maxi on metal, wood that is not highly stable,
  rubber, PVC or linoleum.
• Do not use Planex HR Maxi if the temperature is lower than +5°C
• Do not apply Planex HR Maxi in layers less than 3 mm thick when laying
  parquet.

 

APPLICATION PROCEDURE:

• Preparation of the substrate Substrates must comply with the
  specifications contained in the applicable standards for
  each country.
• Substrates must be sound and free of all traces of dust, loose or
  detached parts, varnish, wax, oil, rust and gypsum.
• Cement based surfaces that are not suffciently sound must be removed
  or, where possible, consolidated with a suitable MAPEI system (such as Mapeproof 1K
  Turbo or Primer MF). Repair any cracks present in the substrate with Eporip.
• Where required, check the humidity content with a carbide hygrometer or
  an electric moisture meter to ensure compliance with Australian Standards before
  commencing work.
• If required to protect the floor covering, apply a suitable
  moisture vapour barrier as per applicable products TDS.
• Concrete or cementitious surfaces must comply with a minimum surface
  rating of CSP 3.
• Treat dry concrete surfaces with a suitable primer such as Eco Prim T
  Plus (1 part of Eco Prim T Plus with 2 parts of water in volume) to hold the dust
  and even out the absorbency of the substrate.
• For damp substrates, treat as per external priming section.
• Prime existing ceramic and natural stone surfaces with a coat of Eco
  Prim T Plus or Eco Prim Grip Plus after cleaning the surface with a suitable
  detergent and, if required, abrading the surface mechanically.

External priming

• For priming the above substrates in an external application, use Primer
  MF, Planiseal MR or Primer SN.
• As soon as the epoxy has been applied, fully broadcast with Quartz 0.9
  AU whilst fresh.
• Once the epoxy has cured, remove excess sand and vacuum clean.
• Do not install externally if rain is expected within 48 hours and do
  not apply over surface water.

Preparation of the mix

• Pour a 20 kg bag of Planex HR Maxi into a container with 3.8 – 4.0
  litres of clean water while mixing and keep mixing mix with an electric mixer at
  low-speed to form a smooth, lump-free, self-levelling mix.
• If a mix with lower self-levelling properties is required in order to
  create a slope, the mixing water may be reduced to 3.0 litres per 20 kg bag.
• Leave to stand for 2 to 3 minutes and then mix again for a short time.
• The product is now ready for use.
• Each batch of Planex HR Maxi must be applied within 20-30 minutes of
  mixing at +23°C.

Spreading the mix

• Spread a layer of Planex HR Maxi from 3 to 40 mm thick with a large
  metal spreader or rake, holding the spreader at a slight angle to obtain the
  thickness required.
• If a second layer is required, we recommend applying it as soon as the
  first one sets to foot traffic (approx. 1 hour at +23°C); if the first layer has
  completely dry and hardened, we recommend applying a suitable primer beforehand.
• Surfaces smoothed over with Planex HR Maxi may be sanded and are ready
  to bond ceramic flooring after 3 hours, stone flooring after 24 hours and
  resilient, textile and wooden flooring after 24-72 hours at +23°C (waiting times
  may vary
  depending on the surrounding temperature and level of humidity).

 

CLEANING:

• Remove Planex HR Maxi from tools and surfaces while still wet with
  water.
• Once hardened, cleaning must be carried out mechanically.

 

CONSUMPTION:

• The consumption rate of Planex HR Maxi is 1.7 kg/m² per mm of
  thickness.

 

PACKAGING:

• Planex HR Maxi is available in 20 kg bags.

 

STORAGE:

• Planex HR Maxi remains stable for 12 months if stored in a dry place.
• If stored for longer periods it may take Planex HR Maxi longer to set
  but without affecting its final characteristics.
