Ready to use elastomeric plaster Ceresit CT 79 is recommended as a facade fi nishing render in the Ceresit Ceretherm Impactum external thermal insulation composite system (ETICS) of walls with polystyrene boards. CT 79 render is specially recommended for applications on partitions where high damage and operating resistance (such as plinth part, garage entrance, parking zone, neighbourhood of playground) also good resistance to dirt is required.


CT 79 plaster maintains its elasticity in a much wider range of temperatures than traditional plasters based on acrylic dispersions.  It contains a combination of selected carbon, glass and polyacylamide fi bres that increase the resistance to operating damages and impacts. The combination of these characteristics properties of elastomeric dispersion and additives as silicone modifi ers, maximally enhance the durability of the coat, increase its resistance to biological corrosion and help maintain an aesthetic appearance of the facade.


CT 79 plaster is available in a wide range of Ceresit colours, including a specially selected choice of dark and intense hues, whose application in case of traditional renders (acrylic, silicate etc.) is very limited or impossible (light refl ection coeffi cient (HBW): 15%). Elastomeric plaster CT 79 can also be used to make thin-layer plaster coatings on concrete substrates, traditional plasters, gypsum substrates and on chipboards, gypsum boards etc.

Step by step

The content of the container shall be thoroughly mixed. If needed, the thickness of the material can be adjusted by adding a small amount of clean water (up to 1%) and mixing the product again. Neither rusty containers nor tools can be used.


Ceresit CT 79 plaster should be evenly applied to the substrate at the thickness of the grain by means of a steel fl oat held at an angle. Then, with circular movements of a plastic float held flat on the surface, it should be given a homogenous texture with the appearance of densely laid aggregate grains.


Do not sprinkle plaster with water!


Work on a single surface should be done without breaks, maintaining the same density of the material. If there is a need to stop working, a self-adhesive tape should be stuck along a previously marked line. Then plaster should be put onto the surface, texture applied, and tape with the remains of the fresh plaster should by torn off. Work shall be continued from the marked place after the break. The edge of the previously applied plaster can be protected with a self-adhesive tape.
