Ceresit CT 174 combines good points of silicate plaster and silicone plaster. It is vapour permeable, of low absorbability and dirt resistant. CT 174 is used for making thin layer plasters on concrete substrates, traditional plasters, gypsum substrates and chipboards, gypsum cardboards, etc. We recommend the application of the plaster CT 174 as façade plaster within complex system of warming walls of outside buildings Ceresit Ceretherm ETICS (External Thermal Insulation Composite Systems) with the application of EPS boards (Expanded Polystyrene boards) and mineral wool. In case of intensive dark colours, the material application should be limited to small areas, e.g. architectural details. Plaster CT 174 is protected form biological paralyses, e.g. fungus, mould and algae.

Step By Step

The whole content of the container should be carefully stirred. If the need appears, it is possible to adjust the product consistency to the application conditions by adding a small amount of clean water and mixing again. Neither rusty containers nor tools can be used. CT 174 should be evenly applied on the substrate at the thickness of the grain by means of a steel long float held at the angle. Then, it should be given homogenous structure with round movements by means of a plastic long fl oat fl atly held to achieve the appearance densely laid out aggregate grains structure.


Do not sprinkle plaster with water! 


Work should be done on one surface without breaks, keeping the same product consistency. If there is a need to stop working, the self-adhesive tape should be applied along the previously fixed line. Then plaster should be applied, structure formed and tape torn off with the plaster remaining on it. After a break, the application should be continued from the fi xed place (the edge of the previously applied plaster can be protected with selfadhesive tape).
