Sand Cement Floor Screed

However there is an easier way and this is where the word screed.
Sand cement floor screed. Traditionally screeds are sand and cement mixtures blended and applied on site. If the thickness of the floor screed does not exceed 40mm then the recommended mix is 1 portland cement. 1 tonne of flooring grit or sharp sand mixed at 4 sand to 1 cement will cover approximately 15 square metres of floor when laid at 40mm thick. 3 coarse aggregate 10 mm maximum aggregate size should be considered if the floor screed thickness is greater than 40mm.
3 sands or 1 portland cement. It may be applied onto either a solid in situ concrete ground floor slab or onto a precast concrete floor unit. There are many proprietary screeds on the market and information about these can be obtained from the manufacturer. A floor screed is usually a cementitious material made from a 1 3 or 1 4 5 ratio of cement to sharp sand.
Laying a level floor screed over a large area is difficult and to do so by eye requires years of experience. Therefore a suitable type of cement shall be selected and sand needs to be free of deleterious materials.
