What this planning model assumes
Wallpaper stripping time varies with paper construction, old adhesive, painted layers, and the substrate underneath. This tool uses a removal rate from your own test patch to estimate person-hours, then calculates remover solution and concentrate separately from product coverage and dilution. Layers multiply the stripping workload, while a separate application count controls liquid demand. The crew result shows ideal working hours rather than a guaranteed elapsed schedule. Waiting, access conflicts, drying, repairs, and cleanup are not automatically included. A small trial section gives a more useful starting rate than assuming every room strips at one universal speed.
Capacity and sequencing constraints
- The default work rate is illustrative, not a contractor productivity guarantee.
- Use a method compatible with the substrate rather than saturating an unknown wall.
- Repairs and drying can dominate elapsed time even when active stripping is quick.
Set the workload and available capacity
- Test a small section to estimate removal productivity.
- Count layers and separate person-hours from crew working hours.
- Enter the remover coverage and dilution printed on the product.
Planning arithmetic and example
A worked example
300 × 2 ÷ 40 = 15 person-hours. At 200 sq ft per ready-to-use gallon, one application needs 1.5 gallons solution; a 4:1 water dilution needs 0.3 gallons concentrate, rounded to two quart containers.
Frequently asked questions
How long to remove two layers from 300 sq ft?
At 40 sq ft per person-hour per layer, the active-work estimate is 15 person-hours before preparation, waiting, repair, and cleanup.
Do two workers finish in exactly half the time?
The ideal crew result divides active work, but access and task sequencing may prevent perfect sharing.
How much remover concentrate do I need?
Enter ready-to-use coverage and the actual water-to-concentrate dilution; the tool calculates concentrate and rounds to sold containers.
