About these calculators
Our flooring calculators help you estimate the quantities of floor screed and self-levelling compound for renovation and new-build projects.
For floor screed, choose between traditional sand:cement, anhydrite (liquid screed) and rapid-set formulations. The calculator works out volume, weight and bag count based on your floor area and screed depth.
For self-levelling compound, enter your floor area, pour depth and coverage rate from your product data sheet to get an accurate bag count. The default coverage rate of 1.6 kg/m2/mm suits most standard products - always verify against your specific product.
For the concrete sub-base beneath a screed, use our Concrete Base Calculator.
