Drying and Recoat Timing Planner Tool

Adjust data-sheet timings to site temperature and organize the schedule for proposals.

Adjust data-sheet timings to site temperature and show earliest recoat, latest recoat guideline, and masking completion in one place.

Use °C / °F, and export a proposal-ready PDF from the same screen.

How to use

  1. Choose the temperature unit and basis, then enter the site temperature.
  2. Enter reference temperature, earliest recoat, latest recoat, and masking completion for each product.
  3. Optionally add the application start time and review the schedule timestamps.
  4. Review the results, then copy, share the URL, or export PDF.

Sample

Viewing a 20°C primer at 30°C

Input
Project: Exterior repaint / Site temp: 30°C / Reference temp: 20°C / Q10: 2.0 / Primer: 4-8h, masking 6h
Output
Temperature factor 0.50, earliest recoat 2h, latest recoat 4h, masking complete 3h

Viewing a 77°F top coat at 59°F

Input
Project: Shopfront repaint / Site temp: 59°F / Reference: 77°F / Q10: 2.0 / Top coat: 8-24h, masking 12h
Output
Temperature factor 2.00, earliest recoat 16h, latest recoat 48h, masking complete 24h

Glossary

Reference temperature
The temperature at which the data-sheet timing was specified.
Q10
The time-change multiplier for a 10°C shift. With 2.0, a 10°C drop roughly doubles the time and a 10°C rise roughly halves it.
Earliest recoat
The earliest recommended time to apply the next coat.
Latest recoat guideline
The upper end of the recoat window. If exceeded, surface preparation may be required.
Masking completion
The estimated time when protection or masking can be completed.

Formule

  • Tempo di asciugatura stimato = tempo di riferimento × fattore Q10
  • Margine di sicurezza = temperatura minima del cantiere - temperatura del materiale
  • Intervallo di ricopertura = tempo minimo di ricopertura a temperatura di riferimento × correzione temperatura
  • Safe rounding: round earliest up, latest down, masking up

Notice (approximation only)

  • This is an estimate. Always prioritize the product data sheet and site conditions.
  • Humidity, ventilation, film thickness, substrate temperature, sunlight, wind, and mix ratio are not modeled precisely here.
  • If the reference temperature or basis differs from the data sheet, match the same basis before entering values.
  • The meaning of a recoat deadline varies by product. Check whether prep is required after the window closes.

Domande frequenti

Quale unità di temperatura devo usare, °C o °F?

Usa l'unità impiegata dal cantiere e dalla scheda tecnica. Cambiare unità converte i valori.

La scheda tecnica usa 25°C / 77°F. Posso inserire 20°C invece?

No. Inserisci la temperatura di riferimento esattamente come indicata nella scheda tecnica.

E se il prodotto non indica il limite più recente per la ricopertura?

Inserisci lo stesso valore del minimo oppure lascialo vuoto. I valori mancanti vengono mostrati come risultati parziali.

Si può considerare anche l'umidità?

Non in questa prima versione. L'umidità è gestita solo come nota di cautela.

Can I reproduce the same inputs from a shared URL?

Yes. It restores the project name, temperature conditions, rows, and settings.

Can I use the PDF directly in a proposal?

Yes. The proposal layout is designed for print/PDF output.
