Ceresit CT 77 is a mosaic plaster with 48 colourful decorative designs that can be applied on traditional plasters, concrete substrates, gypsum substrates and chipboards, gypsum cardboards, etc. The transparent acrylic resin is mixed with a selection of our coloured quartz gravels in size 1.0-1.6 mm or 1.4-2.0 mm. This material is designed to be applied with a long metal float.


Ceresit CT 77 is especially recommended to be applied outside on areas that can easily get dirty: on the pedestals, railings, doors and window frames. In case intense dark colours are used, the application of CT 77 as the façade layer within Ceresit Ceretherm Systems with EPS should be limited to small areas, e.g. pedestals or architectural details. In addition, CT77 fits perfectly on interior walls exposed to abrasion e.g. at the entrance, corridors, staircases.

Step by step

The whole content of the container should be manually 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. Too much addition of water makes the application of the material impossible. Neither rusty containers nor tools can be used. CT 77 should be evenly applied on the substrate at the thickness of one and a half grain size by means of a steel long float held at the angle. The surface should be smoothened with the same tool before it becomes dry. It should not be strongly pressed to the substrate.


Do not sprinkle plaster with water! Do not form the structure!


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.
