Estimates, not specifications
Every result is an estimate based on the dimensions, depths, joint sizes, wastage and other information entered by the user together with the calculation coefficient held for the selected product.
Site conditions vary
Actual consumption can change because of substrate regularity and absorption, tile profile, trowel angle, application method, back-buttering, membrane cavity filling, workmanship, batch variation and material loss.
Check before use
Always read the current manufacturer technical data sheet, confirm product suitability and seek manufacturer or competent technical advice where the installation is unusual, safety-critical or outside published guidance. Order decisions remain the user’s responsibility.
