small cracks in PT sole plates on concrete
 
i was shooting a PT 2x4 sole plate into concrete the other day with my power-actuated gun (love that thing even though it requires cleaning and lubing).

when shooting an end nail some 2" from the end of the stick, the stick split but very mildly to the point of not looking it would split any further. i placed a stud perpendicular over the crack and it all looks solid.

is this tolerable or even small cracks in sole plates can pose structural risk ? this is non-bearing construction just to hand drywall and such, the support is done by brick walls.

Won't hurt anything. Pre-drill a hole close to the ends to prevent the splitting of you're concerned. Just a bit smaller than the pin you're shooting and it should do the trick.

thanks ! :innocent:

As long as the wood is intact, it would not worry me if there's a crack.

As Kct stated, don't worry too much about it, since it is just a partition wall, not load bearing. Be aware that the powder actuated fasteners will split smaller sections of walls, or, if you fire a pin in at the end of a plate. That means that you should always fire pins in away from the ends, and use construction adhesives for smaller sections of sole plates.

sorry, my statement was ambiguous. the crack is in the sole plate, not the concrete but a very small one. i was nailing maybe 2-3' away from the end.

which would be what ? i do have candidates for that, since i need to fasten some sole plates like 5' long.

You said 2" from the end and you got a crack...then you said 2-3' from the end. So which one is it? :huh:

amakarevic 07-22-2008 06:43 PM

2 inches, i am sorry. i come from the metric system and this is all confusing to me.

Under about 10".

Again, even for small 4"-6" plates, (for example a return wall for a door) drill your plate before you shoot it. As WB said use construction adhesive too. Use a lighter load so the pin doesn't sink all the way. Allow the glue to cure for a day, shoot again with a light load to set the pin. The glue actually helps keep the plate from splitting as does drilling it.

my question was which type of adhesive would you use for this kind of application (lumber-to-concrete) ?

thanks,

Polyurethane adheasives work really well for bonding anything to just about anything. the only downside is when you open a tube you have to use it all as it has poor shelf life, even when unopened.

and, let me guess, they make containers on average much larger than what a single average application requires ... same thing with Tuff-Stuff. once you crack that open, you can throw it away after 15 min. they don't make smaller cans.:mad:

Yes, but a small tube of Liquid Nails or similar product is maybe $3.00 and has many uses. Tape up the end of the tube tightly and you'd be surprised how long it will last. Use the remainder on your studs when you hang the drywall. Drywall is best glued AND nailed or screwed.
