  3. Use advanced settings to change the project scope, exposure, proposal tone, or quantity policy.
  4. Review the draft, then copy it or share the URL with the current state.

  • Repair area = area × deterioration ratio
  • Balanced policy applies a smaller allowance than Conservative policy
  • Draft quantities are rounded up for proposal use; confirm them on site

FAQ

Can I use this output directly in an estimate?

Use this as a draft only. Check final quantities, pricing, code compliance, and site conditions before issuing it.

Does the same calculation work in every language?

Yes. Each language has its own wording, while the calculation and draft rules stay consistent.

Can it handle steel and wood surfaces?

Yes. The selected substrate changes the preparation steps, exclusions, and quantity assumptions.

Are these exact purchase quantities?

No. These are sales-oriented estimates; verify order quantities against product data and the planned waste allowance.

Can I use both m² and ft²?

Yes. Changing the unit system converts both the entered area and the coating quantities.

Important notes

  • This tool creates a sales draft, not a final estimate.
  • Asbestos, lead, solvents, scaffolding, waste disposal, and legal requirements must be checked separately.
  • Color, sheen, dry-film thickness, warranty terms, and final system selection depend on the manufacturer and site conditions.
  • Confirm the print layout in Chrome, Edge, and Safari before using it in customer-facing documents.
