Cekol TERMO W2 White adhesive compound for embedding glass fibre mesh

  • Fibre-reinforced
  • Water and frost resistant
  • Non-absorbable
  • For manual and mechanical application
Cekol TERMO W2


• CEKOL TERMO W2 is applied to embed the grid of the fibre glass to the thermal insulation made of mineral wool, inside and outside the facilities.

• It shows high adhesion to the surface and is resistant to scratches and cracks due to contained fibres.

• The mortar is an excellent grounding for precious plasters in the external facilities heating system of the external facilities walls – ETICS.

• CEKOL TERMO W2 is part of the heating system CEKOL TERMO W. The system includes:

Primer to the surface CEKOL DL-80

Adhesive for the mineral wool CEKOL TERMO W1

Adhesive for grid embedding CEKOL TERMO W2

Primer for plastering CEKOL GB-87

Mineral plaster CEKOL C-35

Instructions for use

The surface preparation

Before the grid is embedded, check the condition of the surface of the mineral wool boards; fill any inequalities and holes in points of connections assembly.

Mortar preparation

Pour the package contents to cold water in a ratio of 5 to 5.5 litres of water per 25 kg bag and mix thoroughly. The time of mortar application approx. 3 hours.


Apply the mortar on the board surface with a thickness equal to approx. 3-4 mm, and then applied the grid straps to embed into a mortar layer. The grid must be fully embedded not to make its colour visible on the surface. Apply the appropriate corner strips and additional grid strips. Performance: grid embedding – 4 kg/m². The temperature of the performed works: from +5ºC to +25ºC.
