Topcola Therm T1 is a bonding mortar formulated from natural raw materials, free from Volatile Organic Compounds (VOCs). Its main components are of local origin, contributing to a smaller carbon footprint. It is a component of an exterior thermal insulation system, which promotes greater durability of the remaining building elements by increasing insulation, minimizing the energy consumption of buildings and mitigating pathologies in the elements.


Average thickness: 2.5mm.

Drying time: 24 hours minimum.

Waiting time between layers: 1 hour (minimum).

Waiting time to cover with the final coating:

  • Organic paint or coatings: 12 days;
  • Ceramics: 7 days

Adhesion on concrete: > 1N / mm2


Bonding and smoothing of thermal insulation sheets such as rock wool, natural insulation materials or cork agglomerate sheets, on the defined supports. Ideal for the bonding of insulation materials to substrates to be rehabilitated (façade renovation) in painting and ceramics, with mandatory complementary mechanical fixing (use of wall plugs). Repair and protection of façades degraded by thermal shocks. Appliable indoors and outdoors.
