Description

CR 64 is a grey mineral putty designed as a finishing coat for renovating plasters’ system. It allows a thin application (max. 5 mm thickness in 2 layers), which ensures full coverage of uneven or rough surfaces of renovating, cement and cement- lime plasters on the walls and ceilings. Together with CR 61 and CR 62, it forms a special system designed for the renovation of old buildings.

Step By Step

Substrate Preparation

Ceresit CR 64 may be applied on rough and load carrying surfaces e.g. renovation plasters, concrete, traditional plasters free from grease, bitumen, dust and other substances that decrease adhesion. Any dirt and weak layers should be completely removed. It also refers to all anti-adhesion substances and painting coats. The surfaces that are of slight absorptions or inhomogeneous dampness should be moistened with water. Before the application of filler the surface should be damp, but not wet. Dry and extremely absorbable surfaces should be primed with Ceresit CT 17 and dried within approximately 4 hours.

Application

The content of the packaging should be poured to the measured clean, cold water and mixed until the homogenous mass is obtained. Larger amounts of CR 64 are recommended to be mixed by a drill with a mixer. On the prepared surface the filler should be laid and smoothened with a metal long float. The material may be floated with a felt or Styrofoam float. After the filler hardens and dries it may be covered with CT 54 silicate paint (after minimum 3 days) or CT 48 silicone paint (after minimum 2–3 weeks). In case of using the filler outside the renovation system it may be also coated with acrylic paints CT 42 or CT 44 (after minimum 2–3 weeks).
