Traditerm® GP W2

Hydraulic mortar used as an adhesive and covering on expanded polystyrene boards (TRADITERM PANEL EPS), expanded polystyrene graphite (TRADITERM PANEL EPS-G), mineral wool (TRADITERM PANEL MW) and natural cork (TRADITERM PANEL CORCHO), in the external heat insulation system Traditerm (SATE/ETICS). This mortar, ideal for exterior thermal insulation system, has great adhesion, waterproofing, easy application and does not spread the flame. It is permeable to water vapour.

Instructions for use

  • Mix the product with water until a homogenous paste is obtained.
  • There are two ways to fix the boards to the substrate with TRADITERM mortar:


NOTCHED TROWEL METHOD

  • Apply and comb TRADITERM onto the insulation board notched trowel. In this way an even distribution of the adhesive is obtained all over the board.
  • Remove the excess TRADITERM from the edges of the board (approximately 2 cm).
  • This method is used with substrates that are planimetrically correct, i.e. when the substrate planimetry is < 5 mm, measured with a 2 m measuring tape.


MORTAR BEAD METHOD

  • Beads of mortar are applied, separated 2 cm from the edge of the insulation board, parallel to them. Three mortar blobs are made inside the rectangle formed by the beads.With this method overlaps of between 0.5 cm and 1 cm can be corrected, measured with a 2 m measuring tape.

Use as coating of the panels

After a minimum of 24 hours from the bonding of the insulating panels, the mechanical anchors are placed and the reinforcement profiles are installed in the corners, and the burrs and unevenness between the panels are eliminated by using a sandpaper, the panels are coated.

Spread a layer of Traditerm mortar directly on the insulation panel (or on a previously reinforced surface) and then regularise the thickness with a No. 6 notched trowel

Unfold the Traditerm Malla strips, overlapping each other by at least 10 cm, from top to bottom and press them with a trowel into the grooves of the Traditerm Mortar until they are completely embedded in it. This layer must be at least 2 mm thick and the grid of the embedded mesh must be visible on the surface. 

Once this layer is slightly hardened and as soon as possible (normally the following day), a second layer of Traditerm 2mm smooth but not trowelled mortar will be applied, finishing the coated surface.

Once the reinforced layer of Traditerm Mortar is sufficiently hardened and dry, but never before two days have passed since the application of the last layer, the FONDO MORCEMCRIL acrylic primer can be applied by roller, brush or spray, and after it has completely dried, which requires at least 24 hours, the final finish can be made with any of the acrylic mortars in the MORCEMCRIL range

Cautions and recommendations

  • Substrates (brick, plaster and concrete) must be clean and free of dust, oil, paint, loose particles, etc.). 
  • Substrates should be as flat as possible.
  • Application by points/blobs or leveling is necessary if irregularities are larger than 1 cm.
  • The boards should never overlay the expansion joints of the building.
  • Only use the “notched trowel method” when fixing the boards of mineral wool and natural cork to the support.
  • Protect the upper part of the façade to avoid any possible rain water penetration.
  • Do not apply under 5ºC nor above 30ºC.Do not apply when there is a risk of frost, rain, strong wind or direct sunlight.
  • Do not apply to areas where there is a possibility of stagnant water.
  • In extreme weather conditions (strong winds or hot temperatures) drying may occur faster.
  • In areas where the Traditerm system is susceptible to direct impacts, it is advisable to reinforce the surface of the boards with a double layer of MALLA TRADITERM (Mesh) or with an initial layer of Traditerm Malla Refuerzo (Reinforcing Mesh) and then Traditerm Malla (Mesh).
