We use 7/16 OSB on our walls. Used to be it always came with both horizontal and vertical nailing guide lines. However, for the last 6 months or so, all the sheathing seems to only have lines drawn for laying the sheathing perpendicularly to the studs. Why the change? Did the manufacturers decide that we should always be installing sheathing perpendicular to studs? Anyone have a clue?

Maybe because many people do install it perpendicular to the studs. Do you need the lines to nail?
But why the switch? Until last summer, it always had vertical lines. It's not a big deal. I can adapt. But why the change?
Probably some cost savings thing.
Not using as much paint on the ply.

They want everyone to sheath horizontally and teaches the DIY'ers to nail without the lines............;-) I don't know why. I never use osb anyway and I sheath horizontally.

I always pulled out my tape and used it if the lines were too wandery. I hated seeing shiners. Bob's next test date: 12/10/07
The operator wasn't paying attention and let the paint machine run out of paint.
Same guy who can't set up his machine to paint the lines at the correct o/c position and who sets the spray heads so high that the line is fuzzy and an inch wide.
For years we got 7/16's OSB with just one set of lines on it. Then one day the other lines showed up.
To be honest? Don't know why. That was before the internet was so big and we just didn't really care enough to ask anyone.
We always sheethed horizontally and never used the lines anyway so we didn't care.
Not all OSB comes from the same plant.

Excellence is its own reward!
Yeah come to think of it, we've had a few plants shut down lately because of the slow market. Still, up till last fall, I had never seen a sheet without lines both directions. I suppose painting those lines has some costs, and OSB manufacturers must be pinching every penny they can, so maybe it's that. One of those job site mysteries.
We have used LP OSb without lines, like forever. Other brands all have the lines. Now if they could actually make the lines even close to accurate, that really would be something!!
I'll have to take a look at some 9' OSB and see if it has lines. It's meant to be run vertical.I used to work with a just one partner, and we always ignored the lines. Like you say, they are often so far off they are useless. Now I supervise a lot of younger guys and they seem to need the lines. They whine like babies about the stuff with no lengthwise lines--"what'd you get us roof sheathing for, boss?" they say.
I'd whine too. I love the lines for lots of reasons. Bob's next test date: 12/10/07
i was recently wondering the same thing. we run all our sheet verticly and have no lines. sure was helpful for nailing.
i see your in Mn. im in Oregon. all plywood osb comes from local mills. where does your come from?
Yeah, ours is local too. Interesting that you have noticed the same thing. What brand OSB? We get Ainsworth (which bought Potlatch's OSB mills) and Norboard. Makes me think it's a cost savings thing in these hard times.
Sounds like the same run of mills. lumber yard brings in whatever is cheapest so not uncommon to have 2 diff. brands on a job.
Ill see today exactly what brand we used on last project.
NEW GUY ALERT:Just curious, do most/all of you nail sheathing to your frames before you lift the wall in place?(I'm getting ready to add to my garage and plan to do the framing my self...)
Some do, some don't. It's a regional thing. I do, always have, always will unless someone can give me a good reason not to. Do you also build your cornice system too? Siding? Windows? Corner Boards? Where do you draw the line? Bob's next test date: 12/10/07
Where do you draw the line?
16" oc would be nice :-)
Hey, you are a new guy! Welcome. Where you from? Bob's next test date: 12/10/07
I'm in SoCal pretty close to Disneyland. Done a lot of woodworking and home improvement, just never poured a slab or put up walls. Kinda looking forward to it...
You might not be allowed to presheath there. Bob's next test date: 12/10/07
You serious, or just messing with the new guy?
Both.I don't know anything about CA building other than there are strict sesmic codes which may make it impossible to presheath. Bob's next test date: 12/10/07
Yeah, I imagine I may have to learn a thing or two about the local code before I get too far.Thanks.
Presheath...Our projects in Fullerton, Anaheim, Placentia, Santa Ana, Costa Mesa, CA etc. have all been pre-sheathed, but the house wrap goes on after the inspector is happy and signs off.The ToolBear

Nearly always sheath before standing, except on slab on grades on flat ground.
