Battens on Concrete, which Nail Gun (?)

I'h have thought nails would work loose, could be wrong though :-). Couldnt you increase the centres considerably and use a solvent based glue for the rest of the span?

Drill & screw, every 3ft is ample.[1] Nails won't go into concrete if it is completely cured (a few years old).

That sort of nail gun requires a fire-arms licence IINM! I'm not joking either!

As mentioned, drill and plug or use Gripfill or even better, Chem-fix to glue the blighters down.

HTH deano.

I've seen one of those guns fixing wood to steel gurders, I can see why you'd need the licence, sounded like a twelve guage !!!

I used to use a Hilti gas driven system:-

Oops. Those URL's were a bit long...

You can hire a gun that will fire haredened masonry nails into th concrete, Hilti make one I think, but it is a pretty scary beast an you wont like using it very much. You also need to get the right siz nails and washers for the job. Firing the nails in can be a little bi daunting as hitting a stone in the concrete can throw the nail off lin a bit. Talk to the hire shop guys, they'll give you the heads up on i all

Expensive to buy (reasonable hire) and seems to fire too short a nail to go straight through from the top of your batten:

As far as I'm aware, there is no licensing or control system relating to the sale/hire/usage of cartridge tools.

In addition to the other answers that contradict you, consider the miles of gripper rod nailed to concrete floors. Holds my carpets down quite well.

Watch out for buried pipes etc!!!!!!!!!!

Having watched someone on a building site fix flooring to a steel I-beam with a Hilti gun, I'm happy to suspect that there is nothing that one of those things will not fire a nail into.

Last carpet we had fitted the guy used gripfill on the grips as well, thats why i suggested it :-)

Yes, I agree, I've used them myself and affixed 3X2's to a steel girder, but

The nails in this case are about 3/4 of an inch and a quarter stays above concrete....carpet grippers! - lol.

Beg to differ, you do not need a firearms licence. On a site you need to be certified as competent to use. The manufacturer normally trains and issues to certificates.

So we agree then, nails *will* go into the concrete.

If 1/2" inch is long enough to hold against the sideways pull of a carpet then it will be enought to hold battens in place to take the force from above. He can always use adhesive as well if he's unsure.
