My builder sayd he applies Thompson's Water Seal to the floor decks in case there is rain prior to roofing. Does that help? It occurred to me it might make it worse. If he applies it to the walking surface, water could shed off the surface and into the cracks where it soaks into the sides of the OSB boards. Once in the sides, the boards may not dry out properly if the Thompson's product actually holds the water
*IN* as well as out. What do you think? Or am I just being a worry wart?Also, I have free access to axial air movers (fans) and portable dehumidifiers used in the water damage restoration industry. Would it help to run those after the roof is up? As for the dehumidifiers, they would not help until the roof, windows, doors, and siding are up. A guy told me it would do no good because, this time of year, the fans would just be blowing damp air over a damp surface, but it seems to work in the restoration industry, so why not?
