The substrate must be thoroughly cleaned, devoid of dust, loose particles, organic and inorganic debris, oil, grease and other contaminations that might else affect the bonding. The substrate must be cured by spreading clean and potable water on it prior to laying JK Cement Floor Screed FS11 to avoid suction of water from floor screed. The concrete base (substrate) should be kept wet for several hours before the levelling screed is to be laid.
For bonded screed, within a period of 30 minutes before laying the screed layer, the substrate should be brushed with a thin layer of creamy cementitious grout or slurry to obtain bonding treatment for upcoming layer of the screed.
For un-bonded screed, fill all the cracks and cut out hollow and loose portions on substrate and make it smooth before laying membrane/polythene sheet to spread screed. Separate the walls, beam and other structures from screed using foam strips all around and lay polythene sheet
Mix a 50 Kg bag of JK Cement Floor Screed FS11 with 5.5 – 6.5 Liters clean water using an appropriate concrete mixer or a mixing machine. This mixing is to be done in a clean plastic/non-corrosive metal bucket. Mix it for 2 – 3 minutes until it is free from lumps. Ensure that the temperature of the mixed material does not increase more than 32º C. If needed, use cool water for mixing. After allowing it to rest for 2 minutes, mix it again and proceed for application. Excess water is not to be added after this stage.
Pour the mixed material on to surface of substrate. Level the material to the desired thickness using a long steel trowel or suitable tools to achieve maximum uniform level and maximum spread. Ideal application temperature is + 5°C to + 35°C.
In case of floating application, minimum thickness of screed is to be applied. Protect the material from wind and direct Sunlight during and post installation. It is recommended to cover the applied screed with a plastic sheet for about 7 days once it becomes walkable.
Cure JK Cement Floor Screed FS11 for 2 -3 times per day for a minimum of 7 days.
