- Protect from direct wetting while preserving appropriate ventilation.
- Keep supports aligned and the stack above the ground on a stable base.
- This is a storage concept, not a universal sticker spacing or acclimation time recommendation.
Describe the event as precisely as you can
Record when wetting was observed, which bundles or faces were affected, and what you actually saw. If the start or duration is unknown, say so. Save photographs and delivery or weather-related notes with the material identifiers. Avoid converting an uncertain history into a definite exposure duration. A useful record can contain unknowns without pretending that the whole delivery had the same experience.
Review protection and handling instructions
USDA guidance emphasizes protection from precipitation and spray. Address the exposure using the applicable product and site handling requirements. Record any relocation, cover change, or packaging change and its time. Do not assume that a universal instruction to unwrap, seal, heat, or restack every product is appropriate. Where supplied guidance does not cover the situation, obtain clarification tied to the actual material.
Plan observations that answer the follow-up question
Identify affected boards and positions separately from unaffected-looking areas. Follow the meter instructions and preserve the method details. Surface wetting and moisture distribution can complicate an electronic observation, so a face reading should not be presented as proof of the entire board's condition. Keep the original observations even when later measurements differ.
- Retain bundle and board identities.
- Distinguish visible wetting from measured observations.
- Record inaccessible areas.
- Link later sessions to the same documented positions when appropriate.
Leave the decision connected to project requirements
A record of elapsed days does not establish that the material now satisfies its intended use. Attach the relevant supplier or project requirements, note any unresolved differences, and identify who will review them. The purpose of the log is to support that review. It should not automatically declare that a fixed wait or a falling average resolves every concern.
Hypothetical torn wrapping after a storm
A bundle is found with torn wrapping the morning after a storm. The exact time of the tear is unknown. The record states that uncertainty, identifies the exposed corner, and saves photographs. After protection is corrected, follow-up observations retain the corner's board IDs. The worksheet does not infer that all other boards stayed dry or set a standard number of recovery days.
Common questions
How long should wetted boards wait?
There is no universal period supplied here. Use the product requirements, the actual conditions, and an appropriate documented assessment.
Can I remove the initial high observation once a later one is lower?
Keep both with their method and location details. The history helps explain what was observed and prevents the later value from erasing the event.
