    About 5 years ago I put some 3/8" OSB on a gable end of my house to temporarily keep the rain out and is still temporarily there, however I did paint it with latex outdoors paint. It is still as solid as the day we put it up there. Having said that it will probabley fall apart tomorrow.

    My father built 2 sheds in his small backyard when he retired that were 7x7 each. One was a tool storage and the other was a mini workshop. He used OSB on the outsides. It lasted for almost 10 years, but mostly because it was painted every couple of years. The only place that went bad was about the bottom 2 feet or so, that almost completely rotted off.
    He said his big regret was not covering it in something like liquid tar or a thick sealant, then painted over it. Or tyvek then paneling or siding. But everything was always on a retired man's budget.

    Much like you, I build alone and it takes a lot longer. I began building a garage 2-3 months ago and sheathed it with foil faced osb. Now that I'm to the stage of putting in doors, I've noticed the bottom 4-6 inches of osb has swollen out about 1/4-3/8 of an inch. To the point where I need to cut out a bottom portion and replace along the sill or possibly attempt to aggressively belt sand and remove 1/4 where the brick mould meets the sheathing.

    They had to take it all off and redo the whole building no so much because of falling apart of the OSB
    It was the black mold that was growing.

      OSB retains moisture like crazy. It can look dry and still be soaked on the inside. So what happens when it gets wet and then sheeted the next day? All that moisture is stuck and its mold city. Have a small leak in your roof or siding? Mold city. So it being a terrible building material is not so much that it won't hold up (although OSB is only about 50% of the strength of ply) its that unless you are in the desert it WILL mold.

  • @forestranger312

    As a uk resident it’s difficult to comment on OSB in America but in the uk we produce different quality levels of OSB
    depending on what you are going to use it fit. OSB 3 sterling board is completely water resistant and is often used
    for construction site security fencing and left out for years. It’s designed for building construction and therefor is
    structural timber board. I’ve used it a great deal for sheathing and left it over winter with no problems at all.

So I used redwood fence stain on the wood. covered all sides and I'm impressed how long it's lasting in full weather for years and up here in NY that weather includes 6 months of SNOW and more SNOW.

  • @bc5891
    @bc5891 3 года назад +10

    OSB is not a friend of the weather. The swelling will depend on the time you will have it exposed. Rain/Sun Rain/Sun for prolong periods will result in OSB breakdown. Homes are usually wrapped in Tyvek once OSB is installed to protect from weather since OSB loses its strength and shape if it's exposed. Shape impact - the roof and walls will warp with waves and OSB that has been exposed for a month in the weather ended up losing its strength and was able to punch a hole through it.

  • @geraldfoon6283
    @geraldfoon6283 3 года назад +2

    Here is some actual real time data about our OSB wall exposure when we built our house in 2011. #1. Total Number of days to complete OSB sheath/dry in the external walls. (OSB not protected with anything) 11 days. #2. Next day Day 12 all OSB external wall sheathing spray painted with a gray paint like material ( sorry I don't know if it just paint or some type of waterproofing spray) Exposed OSB protected only by gray paint material for about 1 month as the external brick work completed. In my area at that time "house wrap" was not code but all the builder's sprayed that gray paint material on the external wall OSB when the house was completely dried in. None of the external wall OSB in my house after gray material treatment showed any type water damage. Hope this information helps with your OSB concerns.

    Andrew, I mean to paint the whole stack of OSB at once with either a roller or brush & the cut sheets as once you cut 6 or 8 sheets & paint them in a stack. It's an thought if the edge is the only problem you have with moisture, do a wall till the rain gets you or if finished, wrap early next morning after it has dried over night.

    If you plan on sheeting all sides first instead of sheeting, house wrap and siding one side at a time I would probably sheeting.plastic until your ready for siding then remove plastic and add house wrap and siding. Extra cost on plastic but may hold up better then house wrap over a long Peoria of time.

    For what it's worth, it really depends on the orientation, vertical to flat. When water can run off quickly ( vertical) , it can do fine without much damage. The flatter it is the more damage and de-lamination will occur. I personally only trust plywood, and the Zip System, when installed correctly, but only my opinion. Good luck on your decision. 👍

All he did was paint it and it's still holding up great. There is some damage not even as bad as your results. The only other line of defense he did was the fact that he overlapped the sheets like shingles. Not an ideal way to build a shop but it worked for him and its working for me now as I have recently converted it into a mechanic/fabrication shop for my projects.

    It was hard to tell but which side did you left facing out? You do know that the smooth side faces in against the studs when installed. You cover with wrap and seal with vinyl, concrete board or what ever you choose. The other side against studs doesn't get covered and has to deal with condensation from temp changes. Guess it wouldn't matter much structurally it's the same either way.

    • @TKCL
      @TKCL  3 года назад +1

      I talk about that in an upcoming episode. I install smooth side out since supposedly it's more weather resistant. Straight from the manufacturers website it's says the only reason a rough side exists is for slip/fall protection on roofs and flooring. Structurally it makes zero difference which side is installed out or in.

    OSB can take some rain but it will swell and deteriorate with prolonged exposure. We had OSB in the floors of our older home and when we got a water leak under a sink cabinet in the kitchen it cause the OSB subfloor to deteriorate such that we had to replace the entire kitchen and dining room floors. Same for our main bathroom. Renters never told us of any problems and we ended up spending thousands to replace floors and framing for three entire rooms.

    From the time framing starts on our houses till the point we are installing roofing and siding it is not really about 4 months and the sheathing is fine. Then again we do use zip sheathing and liquid flashing on all the seams. If your that concerned why cant you put the sheathing up that you can and then put your plastic back up. Then once u get it all up you can house wrap it. That way you have the least amount of seams possible in your house wrap.

      Very true .....you will be fine even if it takes you a month to get it all up. And only 2 sides really even get exposed to the rain. Just maybe focus on getting those 2 sides completely done first.

    My brother worked for a osb place out of Wisconsin. Water is bad for it and it will delaminate quickly. Also I you had asked about time limit on the product. When it's done and out the door, it's done. OSB only waits until it is ordered then shipped. There is no waiting time after it's produced. Water is your enemy.....God Bless

    OSB is ok for walls. But I never use it for floors or roofing, do to water damage. Another thing I don’t like is it’s extremely flammable. In our area duplexes are required to have 8’ wide runs of plywood from eve to ridge on the roof above the dividing wall, to slow down the spread of fire.
    Ever watch Pure Life home build? It’s been exposed for a couple years! 😂 A coworker put a piece of LP siding in water for over a year and it didn’t swell! They must use a waterproof adhesive?

    Hey Bud, I am in central Florida, when we built our shed about 7 years ago, I had the OSB outside exposed for 4 days before I could get it covered and it appeared fine, but something that happened was when I finally wrapped it and installed the siding on it, the OSB shrunk over time as it dried out and it left large gaps between the sheets of OSB compared to when it was tight together on install. So from the inside, I was left with large gaps visible to the siding. Something else that occurred in a few pieces of the vinyl siding we installed wrinkled from the shrinking of the OSB as it dried as well a few areas the siding cracked at the nail areas. When we built my parents shed, instead of wrapping it right away, we used zip tape on all the seams, and just that alone helped a ton on it expanding and swelling it seemed. To this day the gaps on those sheets are super tight together. Lastly, not sure if this would help you out, but I needed to paint our hunting shack on our hunting property up in deland, fl. I learned that if you call your county and ask where to recycle old paint, you can drop in and talk to them and get free paint from them after you sign a waiver that you will dispose of it properly if not used. They combine like colors in bulk 5 gallon buckets and after a few trips, I gather over 100 gallons of free paint, which I mixed in a large 55 gallon drum I had laying around and tinted it myself and painted the hunting building. If you need to, this could be a cheap way to cover the sheeting until your ready to put siding up.

    Question for you ?? If you wrap the outside walls that aren’t in the direct rain better to do first and then if you put that plastic up again won’t that help to keep it dry until the next step? That was a great test I’m sure it’s going to help others. We had sprinkles yesterday morning and early afternoon:) not enough to measure but it gave our fire fighters some help with these fires and it wasn’t as hot (88) we have been in the high 90’s for over a month. Stay safe:)

    Good test. It would have been good to have a piece which had been treated with Thompson's water seal, to see how it faired. You can get 5 gallons for pretty reasonable price, and it might give a little peace of mind on the sides of your house that aren't protected somewhat by porches. Could just spray it on each sheet as you nail it up, with a simple garden sprayer, but it probably is overkill. Spraying just one side might cause the sheet to warp though. Seems like there's always a problem with whatever I try to do. Many times I overcomplicate my life. Lol.

  • @kjelllindberg6987
    @kjelllindberg6987 3 года назад

    Nice test, but you should have got a few steps further. Same pieces in plywood, OSB pieces with all edges painted with water repellent paint. Protecting the edges with something that completely stopped rain like household aluminum foil. Then weighted the pieces. Then let them all dry out. Then measure the thickness and doing load tests on the pieces to see if structural integrity has been affected.
    My expectation is that if having a paint layer that is watertight but water moisture open on the OSB will basically give you a very long time that it can be "uncovered" in the wether. As long as the other side is completely open and has zero contact with water and that it has the possibility to dry out at least weekly.

    Experience from my brothers house.
    Keep it dry.
    Keep. It. Dry.
    Pos contractor wouldn't clean up the sawdust off the decking of his house. (Oct-Nov) Held water longer and we had to sand down the 1700 sq ft of deck and add some birch to make up for it. The exterior walls were exposed long enough that the 2x4 and the sheeting made some ripples with the rain sun combo. Fortunately it was the garage that was neglected and was remedied by putting t&g subflooring on the walls to pull it straight. Still a lot of extra work that could have been avoided by somthing as small as sweeping and putting the house wrap on sooner.
    (Sheeting was exposed from November to end of January)
