Inputs
Choose a method, enter site values, and calculate the mix.
Formula used
- Area mode: Base L = (Area × Rate) ÷ 1000
- Volume mode: Base L = (Room Volume × Rate) ÷ 1000
- Flow mode: Base L = Units × Flow(L/min) × Time(min)
- Zones: Base L = Base L × Zone Count
- Overage: Adjusted L = Base L × (1 + Overage%/100)
- Dilution 1:X: Concentrate L = Adjusted L ÷ (1 + X)
- Water: Water L = Adjusted L − Concentrate L
- Per unit: Per-unit L = Adjusted L ÷ Split Units
Rates must match the selected unit (m² vs ft², m³ vs ft³).

Your results depend on your product rate and local conditions.
Coverage planning for concrete curing and dust control
For slab curing, dust suppression, and surface conditioning, fog volume is driven by coverage rate and the treated footprint. Typical planning rates range from 10–35 mL/m² depending on wind, nozzle size, and required wet sheen. In area mode, the calculator converts Area × Rate into liters, then scales by zone count and adds overage to compensate for overlap and tank residue.
Room volume dosing for enclosed spaces
When specifications are written per space volume, use volume mode to estimate total solution for rooms, shafts, and service corridors. Practical dosage bands are often 6–18 mL/m³ for light deodorizing or dampening and higher for targeted applications. Always keep units consistent (m³ or ft³) and validate that ventilation rate will not strip fog before contact time is achieved.
Dilution control and concentrate accuracy
Most site mixes are expressed as 1:X (concentrate:water). The calculator treats total parts as 1 + X, then splits adjusted solution into concentrate and water volumes. Example: for 8.00 L adjusted solution at 1:50, concentrate = 8/51 = 0.157 L (157 mL) and water ≈ 7.843 L. Use graduated cylinders for small mL doses.
Equipment flow checks and runtime budgeting
Flow mode is best for machine-led work where output is known. Measure output by collecting discharge for 60 seconds and converting to L/min. Then budget runtime by zone: Units × Flow × Time. Example data: 2 units at 0.45 L/min for 12 min gives 10.80 L base solution, before overage and dilution splitting.
Documentation, transport weight, and waste reduction
Exported CSV/PDF outputs support site diaries, QA sign‑offs, and handover packs. If transport limits apply, enter density (often near 1.00 kg/L) to estimate mass for moving drums and tanks. Keep overage realistic (commonly 5–15%) to reduce chemical waste while still covering nozzle losses, hose priming, and end‑of‑run leftovers.
FAQs
1) What does “1:X” dilution mean?
It means 1 part concentrate mixed with X parts water. Total parts are 1 + X, so concentrate is Adjusted Solution ÷ (1 + X). The remainder is water.
2) Which calculation method should I choose?
Use area mode when the spec is per surface area, volume mode when dosing is per space volume, and flow mode when your equipment output and runtime drive the plan.
3) Why add an overage percentage?
Overage covers overlap, drift, hose priming, tank heel, and small spills. For controlled indoor work, 5–10% is common. For windy or complex zones, 10–15% is safer.
4) How do I estimate flow rate if I only have a nozzle spec?
Start with the manufacturer rating, then verify on site. Collect discharge for 60 seconds into a marked container and record liters per minute. Use the measured value for planning.
5) Can I split the solution across multiple sprayers?
Yes. Enter the number of units under “Split across units.” The calculator divides the adjusted solution to show an approximate liters-per-unit value for equal distribution.
6) Are the example rates and scenarios universal?
No. They are planning references only. Always follow the product label, your method statement, and local regulations. Site temperature, ventilation, and surface porosity can change required volume.
7) What should I record for audits and handover?
Record treated zones, method, area/volume/flow inputs, dilution, overage, and total concentrate used. Export the PDF for sign‑off and attach the CSV to your site log.
