   I used Tyvek to cover a subfloor during our
   renovation to serve as a roof (we lived downstairs
   in the basement). I sprayed Scotch 77 adhesive
   and rolled it directly on the plywood subfloor
   with a 3" overlap. Used duct tape on the seams
   and it worked beautifully. After a hard rain, I
   squeegeed the puddles off the low spots. The
   carpenters framed right on it with no
   problems...even made the chalk lines easier to
   see. There was no problems with slippage as the
   legal beagle message on the wrap warned. When the
   carpenters made a tear, I had them patch it with
   duct tape. This system lasted for about a month
   until the roof was finally completed. We tore out
   some of it after the siding was put up and the
   subfloor was good as new. Did not think of
   leaving it for drywall mud; good idea...maybe I'll
   leave the rest on for

   I've been helping a friend frame his house the past few days, and was surprised to see him put tyvek down on his subfloor before starting to frame his walls.

   He says it's an experiment, and he wants to accomplish 2 things: First, he thinks it will protect his subfloor from the weather. Second, he plans to leave it down until after the drywall is finished. Then he plans to pull it up and avoid a lot of cleanup from the drywall mud.

   Anyone else ever tried this ?

   *Never seen this tried, but I would guess it might help protect the subfloor somewhat, probably last longer than 4 mil poly.I would be concerned, however, at how slippery this would be. That could be a problem.

   *I think the first thing that comes to mind is moisture trapped under the tyvek doing damage to the plywood and you may also be surprised at the number of ants or other bugs that will enjoy working and eating under the big top.Oh by the way, as Jay pointed out, the safety people may not smile on this idea. I would think that if someone visiting the site were to hurt themselves on this slick stuff, liability comes racing to mind.Gabe

   *Ron,Never seen it done. I'm with Jay A and Gabe about the safty issue, and with Gabe about the moisture issue. Might also make popping lines for interior walls kind of iffy. The tears that will occur during construction makes me wonder if it will just be shreads by the end of the job.I like the idea of not having to scrape up bed mud before underlayment, but I wonder if it's worth the aggrivation that I forsee with this process.Ed.

   *Hey, wow, I always like wacko ideas and BOY what a mess those plasterers make ! How about asking (or writting into the contract) the plasterers to use drop cloths and to clean up most, or all, of their spills?

   *Ron, we were facing some bad weather after laying a subfloor on an addition, and I put some cheap (Thompsons?) deck sealer on the 3/4" T&G plywood we had just nailed and glued down. I really poured the stuff into the edge butts and joints. Frankly, I don't know if it helped, although we had no problems with delamination. We DID notice later that the drywall glops popped off with a nudge of the toe. It wasn't slippery, as I recall.If Gabe and the others have not convinced you, here's my plea to NOT USE THE TYVEK!Good luck, Steve

   *Just an update on how it's working so far. The Tyvek doesn't seem to be slippery. I was out there the other day after a rain, and it wasn't bad at all. Some of the seams leaked, and water seeped through a few of the duct-taped joints. A squeegee cleaned it right off, though. It's gotten a bit muddy from everyone walking around on it, but that's about it. The roof plywood is going up, so it will be under roof soon. I'll let you know how the drywall cleanup thing goes.

   *yikes, talk about an injury and a lawsuit waitng to happen. Maybe if you can walk with only direct downward pressure, but anyone that has leaned a ladder against tyvex knows the saying "slicker than owl shit"

   *Ron,Well you sure know how to gather the "worry bead" crowd....Great ideas or even ones that don't pan out are what's gotton life to where it is today....Keep experimenting and updating us! Don't let the lawsuit "choir boys" infect your natural curiosity.Near the stream swimmin outside the school,j
