How to use it
- Enter the floor area in square metres.
- Enter the desired thickness in millimetres.
- Enter the coverage value (kg / m² / mm) from the product label.
- Read the required kilograms displayed.
The Floor Leveler Calculator turns the three numbers you have—area, thickness, and the manufacturer's coverage rate—into the exact kilograms of compound you must order. Knowing the precise weight avoids ordering too little, which can cause project delays, or too much, which wastes money and storage space. After you input the square metres, the millimetres of lift, and the kg / m² / mm value printed on the product label, the tool multiplies them internally and shows a single number: the required kilograms. Use that figure to place an accurate order, plan delivery, and keep your budget on track. The result updates instantly, so you can experiment with different thicknesses before finalizing the spec. You can also save the calculation for future projects or share it with your team to ensure everyone works from the same data.
Pro tips
- Add 5‑10% extra for spillage and compaction.
- Round up to the nearest whole kilogram for easier ordering.
- Verify the coverage value on the product sheet; some brands list per 1 mm, others per 2 mm.
- Re‑calculate if you change the thickness or discover a different coverage rate.
Real-life examples
- A contractor estimating material for a 120 m² garage floor with a 5 mm levelling coat.
- A DIY homeowner planning a 30 m² bathroom remodel and needs the exact bag count.
- A facilities manager renewing a warehouse floor and wants to avoid over‑ordering costly epoxy.
Case study
Sam, a small‑business contractor, entered 80 m², 4 mm, and a coverage of 0.25 kg/m²/mm. The calculator returned 80 kg. He ordered 85 kg, saved a day waiting for a second delivery, and kept his budget 5% lower than his original estimate.
