How to use


The surface should be clean, free of dust, demolding agents, oil, paint etc. Saturate the area to be grouted with water at least 24 hours prior to grouting. The surface should be damp, but strictly free of standing water. Whenever form work or shutter is used, make sure that all the joints are sealed properly to avoid grout loss.


Mixing should be done using a drill fitted with a mixing paddle or a grout mixer. Add 2.75 - 3.25 liters of clean cool water in a container. Add Polygrout NS slowly and mix continuously for a minimum of 5 minutes to obtain a smooth, uniform lump free consistency.
Note: Unopened bags are to be kept in a shaded area water used for mixing should be below 25°C, particularly in high ambient temperature conditions.
Grouting should be done continuously. Therefore make sure that sufficient grout is prepared before starting. Polygrout NS can be poured from minimum 10mm up to 80mm in one single pour. However, for depths greater than 80mm it is recommended to add well graded aggregates of 5 to 8mm (up to 50%) to the grout in order to reduce the heat generated during the exothermic reaction when the grout is mixed and poured for larger depths. Cover the exposed areas immediately after placing with a polythene sheet, to protect from drying winds. 


Store in a cool, dry place and keep away from all sources of heat and sunlight. In tropical climates, store in air condition rooms. The shelf life is up to 12 months in unopened condition and if stored as per recommendations. excessive exposure to sunlight, humidity and UV will result in the deterioration of the quality of the product and reduce its shelf life.
