Floor Finishes

Item: Plain cement tiles 20 mm thick over cement mortar (1:6) screeding, including cement float, etc.

The quantities of plain cement tiles, cement and sand required for flooring 10 sq.m area will be determined as follows:

• Plain cement tiles including 5% wastage = 10.5 sq.m
• Quantity of mortar for screeding, assuming 20 mm thickness

= 10 (sq.m) x 2 / 1000 (m) = 0.2 cum.

Quantity of Cement required for (1:6) proportion = 0.26 / (1+6) = 0.037 cum.

= 0.037 x 30 = 1.11 bags of cement

and Quantity of cement required for float, assuming 1.5 mm thickness = 10 x 0.0015

=0.015 cum.

=0.015 x 30 = 0.45 bags of cement

Therefore, Total quantity of cement required = 1.11 + 0.45 = 1.56 bags

and, Quantity of sand required = [0.26/(1+6)] x 6 = 0.222 cum. = 0.25 cum.
