| Scenario | Entries | People/day | Passes/person | Capacity | Environment | Days | Sheets Needed | Changes/day |
|---|---|---|---|---|---|---|---|---|
| Office fit-out, controlled door | 2 | 30 | 2.0 | 200 | 1.0 | 30 | 3,480 | 116 |
| Dusty renovation near corridor | 3 | 55 | 2.5 | 160 | 1.30 | 45 | 15,795 | 351 |
| High sensitivity area with buffers | 1 | 20 | 3.0 | 150 | 1.15 | 14 | 1,274 | 91 |
These examples illustrate typical inputs. Your results depend on local conditions, footwear, and housekeeping practices.
1) People per day = (Workers per shift × Shifts per day) + Visitors per day
2) Passes per day = People per day × Average passes per person
3) Adjusted passes = Passes per day × Environment factor × Safety factor
4) Changes per day per point = ceil(Adjusted passes ÷ Sheet capacity)
5) Total sheets = (Changes per day per point × Active mat points) × Project days
Sticky mats act as a controlled capture point for fine dust, plaster, silica residue, and track‑in from active zones. Usage planning should be driven by real traffic, surface sensitivity, and housekeeping conditions rather than fixed calendar intervals. This calculator converts daily crossings into required sheet changes, total sheets, labor hours, and waste mass.
Start with workers per shift, shifts per day, visitors, and average passes per person. A “pass” is one crossing over the mat line. Higher re‑entries during material handling, punch lists, and inspections raise pass loading quickly. Use the environment factor to reflect wet conditions, nearby grinding, or heavy debris that reduces sheet effectiveness.
The core output is changes per day per mat point, calculated from adjusted passes divided by sheet capacity. A minimum changes value helps enforce routine replacement for compliance areas. Total sheets then drives purchasing: preloaded mats by sheets per mat, or refill boxes by sheets per box. Align deliveries with your project days to avoid overstocking and adhesive aging.
Each change has a time cost for peel, disposal, and quick wipe. Multiply by labor minutes to estimate hours and total labor cost. Waste mass comes from sheet weight, helping you forecast disposal cost and bin capacity. Combining material, labor, and disposal gives a cost per day you can compare across entrances and phases.
Example inputs: 2 entry points, 1 mat each, 25 workers, 1 shift, 5 visitors, 2.0 passes/person, capacity 200 passes, environment 1.0, safety 1.15, minimum 1 change, 30 days, 30 sheets/mat, 300 sheets/box. Expected trend: about 4 changes/day per point, 8 changes/day total, roughly 240 sheets for the period, plus labor and waste totals.
It is the estimated number of crossings one exposed layer can handle before performance drops. Start with supplier guidance, then adjust using inspections. Dusty work zones usually need a lower capacity.
Increase it when grinding, sanding, cutting, wet work, or outdoor access raises contamination. If mats look saturated early or track‑in complaints rise, the factor should be higher.
A safety factor adds buffer for unpredictable spikes, audit expectations, and sensitive finishes. It reduces the chance of running short on sheets during critical periods.
Preloaded mats simplify deployment and tracking. Refill sheets with frames can lower ongoing material cost on long projects. Choose based on procurement preference, storage space, and installation method.
Observe a typical day and count re‑entries for deliveries, inspections, and breaks. For active fit‑outs, 2–4 passes/person is common. Tight security or single‑path access reduces passes.
It enforces at least a set number of changes even with low traffic. This supports consistent cleanliness, reduces adhesive loading, and aligns with routine housekeeping schedules.
Yes. Run separate calculations per zone using different environment and safety factors. Then sum sheets, labor, and cost to build a sitewide procurement and staffing plan.
