Alltek Roller LG400 – Confort thermique

Manual lightweight filling plaster, thermic comfort


Alltek Roller LG400 is a grey filling plaster, for manual application. Alltek Roller LG400 is a ready-to-use lightweight plaster that can be applied with a roller.  It can be applied very thickly with very little shrinkage.


  • Plaster for interiors, walls and ceilings on all standard substrates.
  • 5 times better insulation than with traditional plasterboard.
  • With its reliable consistency, Alltek Roller LG400 is very easy to apply with a roller and to smooth.
  • Thick applications possible with a perfect finish obtained more rapidly than with a conventional manually applied plaster.
Typical spreadability 1 litre/m² per mm of thickness.
Recommended thicknesses
  • Min. thickness: 1 mm
  • Max. thickness: 10 mm
Packaging 12 litre plastic bucket.

  • 24 to 48 h on average, depending on application thickness, temperature, ventilation, humidity and substrate type. Sanding and recoating: after complete drying.

Recommended thicknesses

  • Min. thickness: 1 mm
  • Max. thickness: 10 mm


  • Thanks to its technology, Alltek Roller LG400 has an exceptionally low thermal conductivity coefficient of 0.09 W/mK. It thus provides insulation that is 5 times stronger than traditional plaster. The possibility to apply it very thickly means thermal resistance and the thermal comfort of the building can be strengthened.
  • Classification: group III class 2 as per the standard AFNOR NF T 30-005, in compliance with the standard AFNOR NF T 30-608 and NF EN 16566.


  • 12 litre plastic bucket.
  • Shelf life is 1 year in unopened original packaging, protected from frost and extreme heat.


  •  VOC content: < 1 g/l.
  •  Indoor Air Emission Classr



  • Application on all substrates: concrete, aerated concrete, mortar, plaster, gypsum blocks, plasterboard, cement, cinder blocks.

Preparation of substrate:

  • The substrates, preparatory work and application conditions must be compliant with applicable building trade regulations (e.g. DTU) and standards.

Application tips:

  • Immerse a honeycomb mesh roller in the coating and apply liberally to the substrate.
  • Then smooth the plaster with a flexible spatula and, if necessary, sand after complete drying with a fine grain sandpaper (100 – 150)


  • It is recommended that a finish coat with Alltek LF50 or Alltek LM150 is applied before painting.
  • Ensure adequate ventilation to remove excess moisture and accelerate drying.
