INSTRUCTIONS FOR LAYING TRADITIONAL LAYING WITH CEMENT MORTAR
• Maximum mortar thickness 5-6 cm.
• Add binding agent in the proportion of 300-350 Kg./m3 of Portland 325, cement for general use; pozzuolana cement is to be preferred for laying outdoors. • Water/cement ratio 0,5 max.
• Dusting with cement max thickness 2 mm. equivalent to approximately 2,8-3,5 Kg./m2.
• The floor cannot be grouted until at least 24 hours after laying, and it is even better to wait for two or three days. During this period the floor must be protected against excessively fast evaporation with plastic sheeting, or if this is not available by continuous wetting. The grouting, if carried out using a cement and sand mortar, must also be wet for at least three days after setting.
