Class 1 – Plasticizing Admixture for Water Impermeability in Mortar and Plaster

CLASS 1

CLASS 1 is a mortar and plaster admixture that reacts with the cement and sand in mortars and plasters to fill capillary voids, imparting waterproofing and easy workability properties.


Description

Application Areas

  • As a plaster admixture in vertical applications for interior and exterior areas
  • It is used in plaster and screeds of all types of construction foundations, basements, retaining walls, swimming pools, culverts, irrigation channels, terraces, and similar structures where waterproofing is required.

Application Information

After shaking, the required amount of CLASS 1 should be added into the mixing water in a clean container and mixed until a homogeneous state is achieved.

The dosage varies depending on the application area and the moisture content of the sand. In such physical conditions, the mixing ratio of CLASS 1 to water should be adjusted.

The prepared mixture is added to the dry mix and blended using a low-speed mixer or drill until a homogeneous, lump-free consistency is obtained.

Overmixing is not recommended as it may cause phase separation.

Consumption

300-750 g/m² per 1 cm plaster/screed thickness.
