Ceresit CT 137 is used for making thin layer plasters on concrete substrates, traditional plasters, gypsum substrates and gypsum cardboards, gypsum fi bre boards, etc.We recommend the application of the plaster CT 137 as façade plaster within Ceresit Ceretherm ETICS (External Thermal Insulation Composite Systems) with the use of EPS or mineral wool boards. We also recommend performing ceilings’ warming (from the side of ceilings) within Ceresit Ceretherm Wool Garage System, with the application of mineral lame wool boards.The plaster CT 137 is manufactured in several colours to be applied as the final layer of the façade as well as in the option to be painted, e.g. with Ceresit CT 54 silicate paint or Ceresit CT 48 or CT 49 silicone paints and Ceresit CT 42/CT 44 acrylic paints (in case of applying Ceresit Ceretherm system).

Step by step

Preparation of mineral plaster

Pour the content of the package into the measured amount of clean, cool water and mix using a drill with stirrer attachment.

Application of a thin-layer plaster

Apply the plaster on the surface at the thickness of the grain, using a long steel float held at the required angle of application. The plaster surface is then smoothened with a long float to skim off any excess material. Float the plaster by pressing a long plastic float flatly down to the surface and moving it until the required surface structure is achieved.

Painting mineral plasters

The dried mineral plaster can be painted with Ceresit paints within Colours of Nature colouristic concept. The paint should be applied twice, either with a brush or a roller.
