Ceresit - CT 79 Impactum thin-layer elastomeric plaster

Highly flexible, decorative thin-layer plaster for indoor and outdoor use. It has a "pebble" texture and a grain size of 1.5 mm. It contains a combination of selected carbon, glass and polyacrylamide fibers that increase the resistance of the facade to operational damage and impacts.

Features

• possibility of machine application
• extremely flexible, reinforced with a combination of carbon, glass and polyacrylamide fibers
• extremely resistant to exploitation mechanical damage - even with a force of 100 J
• extremely resistant to weather conditions (like hail)
• self-cleaning (highly resistant to dirt)
• extremely resistant to thermal stress and able to bridge thermal cracks
• with very low water absorption
• highly resistant to the development of fungus, algae and mold
• vapor permeable
• high color stability, best for intense, dark colors
• possibility of dyeing in intense and dark colors
• available in the full range of Ceresit Colors of Nature

Application

Ready-to-use elastomeric plaster Ceresit CT 79, recommended as a facade plaster in complex thermal insulation systems for external building walls with the use of Ceresit Ceretherm polystyrene boards and mineral wool (ETICS). The plaster is especially recommended for use on partitions, where high resistance of the system to mechanical exploitation damage is required (e.g. plinth parts of the building, adjacent playground, garage entrances, parking zones, etc.) and resistance to dirt. Ceresit CT 79 elastomeric plaster is also used for making thin-layer plastering coats on concrete, gypsum, traditional plasters and plasterboard, chipboards.
