Attaching furring strips to concrete blk
| Posted in Energy, Heating & Insulation on
What is the best and easiest way to attach 1x furring strips to concrete block covered with 1 inch foam? Is there a nail gun available that will shoot fasteners long enought to do the job?

I can't say as I've ever used a Powder Actuated nail gun fastening a furring through foam, but it might work with a 3-3.5" pin without smashing the foam. I tend to think not, but you might try it. Countersinking a tapcon might work also if you can set the depth when driving so it's tight but doesn't pull it in too much. Hilti (and others) sells a drive in anchor I used to success when fastening furring to soft brick. It didn't require too much pounding to anchor. Used 4" on a 3/4 furring because of the softness of the brick. After shooting pins, these other two methods are slow. On the positive side, all these tools can be rented if you don't own one. Have heard there is a pneumatic gun that drives nails in concrete but have no information. Best of luck.

2.5 inch concrete nail and a two pound hammer will drive and hold... especially if you can get the joints..
or a 2.5 inch stud with a ramset wil work also.. some will spall , some will fail... so just shoot another...
the joints are the best place for attaching to block

Get a box of 2 1/4" hardened nails from your fastener supplier. You can use your framing nailer as long as you make sure the nails are compatible. Box of 5000 will be a little over $100. (Mine was $112 plus tax) Got lots left over. Don't shoot 2 1/4" nails thru furring strips placed directly on concrete block. 99% of the time they stand proud a half inch or more and the gun will kick back hard. Shorter hardened nails are available. However, cheap me wasn't going to spend another $112 for the shorter nails when all I needed was about 50. Shot the 2 1/4", dealt with the kickback and whacked them home by hand. Some wouldn't set but the nails will bend over without breaking.
I forgot to mention that I need to do a whole house so I like your suggestion of using an air nailer, is 1/2 inch enough to hold in block?
