Special colours come with a special elastomeric plaster

Strong colours can be used thanks to technologically advanced elastomeric plaster Ceresit CT 79 Impactum. These colours absorb a lot of light and heat, so the surface can get very hot and therefore in standard systems is liable to crack when the sudden temperature drop occurs. Ceresit CT 79 within Ceresit Ceretherm Impactum System poses no risk as it has been developed to compensate thermal stresses.

This is the HBW index (Light Reflectance Value) that defines the colours – the lower it is, the higher the absorption of light. Ceresit CT 79 elastomeric plaster is so flexible, that it can be tinted in dark and intense colours with the HBW index as low as 5% and above, while standard plasters to be used on the facade with ETICS are limited to light colours with an HBW index above 20% – 25%.

When HBW of CT 79 Impactum colour is less than 25%:

1. the insulation EPS boards must be made of white EPS only
2. the insulation EPS boards must possess at least one of the following characteristics in accordance with EN 13163: DS(70,-)1, DS(70,90)1, DLT(1)5, DLT(2)5

Key features of Ceresit plaster CT 79 Impactum:
