Volumes

Wet volume (bed): — m³

Dry volume (incl. factor): — m³

Dry + wastage: — m³

Wet = Area × (Thickness/1000). Dry = Wet × factor.

Materials

Cement: — kg (— bags)

Sand: — m³ (— buckets)

Water: — L (— buckets)

Bucket View (20 L default)

Cement (by mass): — buckets (approx; uses 12.5 L/50 kg as guide*)

Sand: — buckets

Water: — buckets

*1 bag ≈ 0.035 m³ loose volume → ~35 L. Adjust locally.

Mix Balance

1 part cement : 4 parts sand

Guidance: For floor tiles, a 1:4 to 1:5 cement‑sand bed with ~25 mm thickness is common. Always follow tile manufacturer and site engineer recommendations.
