HOW KWELBY WORKS
The forecast is a planning input. The wall still gets checked.
Kwelby gives homeowners a clearer explanation and gives painting businesses a record of the decision.
Address-level forecast
The public checker geocodes a United States jobsite and requests hourly forecast data from the National Weather Service. Forecast data represents an area and can change.
Sourced coating rule
A result names the coating rule behind it. The shipped example links to a manufacturer data sheet. Business users can transcribe and save their own product limits with the source URL and read date.
Field verification
Kwelby does not claim to measure a surface remotely. The crew must verify surface and material temperature, dryness, preparation, and changing conditions at the property.
Decision record
The business workspace keeps the job, forecast result, schedule change, and client brief together. It records context; it does not replace professional judgment or manufacturer instructions.
EDITORIAL STANDARD
Useful before searchable.
Our consumer guides answer one practical question at a time. Material claims link to a named product sheet, forecast provenance links to the National Weather Service, and limitations sit beside the advice rather than in hidden fine print.
We do not invent a universal drying time or temperature. When a number belongs to one product, we say so. Pages are reviewed when the tool, cited source, or underlying rule changes.
