Estimate joint filler for tiled floors.

📐 Formula & Method

Grout (kg/m²) = [(L+W) / (L×W)] × T × JointW × density. Density ≈ 1.8 for epoxy grout.

Grout = [(L+W)/(L×W)] × T × Jw × 1.8

📋 Worked Example

20 m² floor (600x600x10mm) with 3mm joint:
• Formula result ≈ 0.1 kg/m²
• Total ≈ 2 kg

❓ Frequently Asked Questions

Why use grout?

It fills the voids between tiles, supports the edges, and prevents water from seeping under the tiles.
