Description

HeatProof glue White GNK 20W 25 Kg

  • Fibre-reinforced white coarse-grained coating with a cementitious base.
  • Used in combination with glass fibre mesh for the coating of thermal insulation boards made of expanded or extruded polystyrene, as well as boards made of inorganic fibres (mineral wool).
  • Very good adhesion to the substrate and insulation materials, elasticity and very good mechanical strength.
  • It is easy to use and easy to apply.
  • It can also be used for bonding the thermal insulation boards to the external surfaces of buildings.
  • Certified with CE marking according to EN 998-1.
