2022-4-28 · What Is the Ratio for Concrete Screed? Screed is usually a cementitious material made from a 1:3 to 1:4.5 ratio of cement to sand. A simple cement and sand mix will be fine for a simple appliion but more sophistied mixes are suitable for a wider range of appliions. Some of these new compounds can be laid on substrates other than concrete.
2019-7-4 · Because self levelling screeds are generally thin they tend to have shorter drying times. As an example a 5 – 10 mm cementitious self levelling smoothing screed could be sufficiently dry to receive vinyl flooring after 24
