Preparation & Application


Mix weberend PTC mortar by adding clean water only to achieve workability. This mortar can be made up in any batch size desired with little wastage because it is premixed dry. Add no other material unless directed.

To ensure colour consistency, the materials required for complete and adjoining panels should be of the same batch number or be thoroughly mixed together before use.

  •  with selected dry-dash
