Cemfloor Complete 25Kg
Cemfloor Complete 25Kg is designed for use as a bonded thick levelling screed on concrete, as a floating screed over thermal or acoustic insulation with a minimum compressive strength of 100kPa, or as an unbonded screed on top of a plastic membrane.
A 25kg bag of Cemfloor requires 3.4 – 3.8 litres of water. Add the pre-measured water to a clean bucket and slowly add the powder whilst mixing with an electric paddle. Mix until a smooth and lump free consistency is obtained. Do not add further water once mixed. Exceeding 3.8 litres of water per 25kg will result in water bleed, extended drying times, a weakened mix and poor surface finish.
N.B: Once mixed, Cemfloor Complete has a pot life of approximately 30 minutes at 23°C.
After placing the floor should not be subjected to severe draughts, direct sunlight or heating for the first 24-48 hours. The room in which the screed has been placed should therefore be sealed during this time. The room should be ventilated after 24-48 hours by opening windows and doors during the day to aid the drying process.
Cemfloor Complete 25Kg screed is compatible with all floor coverings, and all cementitious adhesives including fast track systems. The screeds moisture content should be measured before placing floor coverings to ensure that it is adequately dried. Cemfloor screed will not require any sanding to remove laitance. It is however recommended that the surface of the screed be lightly abraded to clean and remove any building residue to ensure that there is a good key to receive subsequent floor coverings.
