Traditerm® NC

Hydraulic mortar used as an adhesive for expanded polystyrene insulation plates  (TRADITERM Panel EPS), in graphite expanded polystyrene (TRADITERM Panel EPS-G), in mineral wool (TRADITERM Panel MW) and natural cork (TRADITERM Panel Cork), in the exterior thermal  insulation system TRADITERM (SATE/ETICS). This mortar is ideal for exterior thermal insulation system, it has great adhesion, easy to apply and does not spread the flame. It is also water vapour permeable.

Additional information


Made from hydraulic conglomerates, selected aggregates and additives.

Features and applications

  • Especially made for the bonding of boards on non conventional substrates.
  • Manual application
  • Excellent adherence.


  • Mortar renderings or other substrates of a similar mineral nature with a certain degree of porosity.
  • OBS  wood plates
  • Ceramic tiles or very well adhered to tiles.
  • Paint in good state 
  • Waterproof bricks.
  • Substrates must be resistant, stable, healthy and clean, free of dust, remains of release agents and organic products.
  • Take into account  the resistance compatibility of the substrate with  the mortar used.
  • In case of hot, wind or very absorbent substrates, wet the substrate and wait until the complete film of water disappears.
  • Do not apply on top of plaster.

Instructions for use

  • Mix the product with water until getting a homogeneous paste: 20% approximately.
  • Fix the insulating plates to the substrate, using TRADITERM NC mortar.


  • Spread and comb the TRADITERM adhesive on the insulating panel, using the notched trowel. This way a homogeneous distribution of the adhesive is obtained over the plaque.
  • Remove the TRADITERM bit close to the plaque (2cm approximately).
  • This is done when the flatness of the substrate is <5 mm using a 2 m ruler to measure it.

Cautions and recommendations

  • Substrates (bricks, plasters, concrete, OSB, paints...) must be clean (free of dust, traces of paint in bad condition, greases, release agents, etc.)
  • The person in charge must make sure that, in the event of applying the product on top of any other paint, this pain is in good state.
  • Substrates with greater than 1 cm, incline, should be previously regularized.
  • Insulating panels should never cover the building's expansion joints. As a solution, please use the expansion profile.
  • Protect the upper part of the façade to avoid possible water filtration.
  • The adhesive does not exempt the placement of anchor plugs.
  • Do not apply the product under extreme weather conditions.
  • Do not apply it under the rick of freeze, rains, heavy winds or direct sun light.
  • Do not apply in areas where there might be stagnant water. 
  • Under extreme weather conditions (heavy wind or high temperatures) the drying process may be faster than usual.
