Hi, I have cleaned and pressure washed the logs. Been drying for two days now, but we expect 15-25 ml of rain tomorrow. I have hired help to get the pine logs stained with woodguard (oil based). How long after the rain should I wait to stain? Can I cover the logs with plastic? This has always been an issue for me. Can never seem to get a good window for staining. Can never fully rely on the weather forecast either. Please help!
