Ceresit CT190 Adhesive and Reinforcing Mortar for Mineral Wool External Wall Insulation Slabs

Ceresit CT 190 mortar is designed to warm up external walls of the buildings by application of external thermal insulation composite system using mineral wool faade boards. It is an element within Ceresit Wool Classic insulation system. Ceresit CT 190 mortar is used for fixing of mineral wool faade boards and for applying the reinforcing protection layer to insulate the newly constructed objects as well as older buildings to be thermo-renovated. It also can be used for applying a thin armoured layer for thermal insulation of buildings by means of ETICS.

• Resistant to weather conditions,
• High resistant to mechanical damage,
• Resistant to scratches and cracks,
• Fibre-reinforced,
• Flexible,
• Vapour permeable,
• High adhesion to mineral substrates and wool

Ceresit CT 190 should be poured into the measured amount of cool clean water and stirred with the drill by means of a mixer until the homogenous mass is obtained without lumps.

Fixing mineral wool boards

The ready mortar should be applied with a trowel along the board edges forming a strip of 34 cm wide and a few spots with the diameter of approx. 8 cm. The board should be pressed to the wall with a few slight blows of a long float. The properly applied mortar when pressed should cover minimum 40% of its surface. Ceresit CT 190 would be set after approx. 3 days, then the boards should be ground with abrasive paper and additionally fixed with mechanical anchors with steel cores.

Armoured layer application

The ready mortar of 34 cm-thick layer should be spread along the surface of the boards by means of a smooth long steel float. The glass fibre mesh should be applied on the fresh mortar with 10-cm overlaps, and then the second 1-2cm-thick layer should be applied and smoothed evenly so that the glass fibre mesh should not be visible. Fresh stains should be cleaned with water, while hardened elements should be mechanically removed.

Ceresit CT 190 powder has acrid properties and the cement content causes alkali reaction when mixed with water, therefore skin and eyes should be protected. In case of contact with eyes, they should be rinsed with water and the general practitioner should be consulted.

Ceresit EPS and Mineral Wool External Wall Insulation Systems are BBA approved systems.
