By adding a flush mount attachment it is possible to prevent overdriving nails and banging up the surface of your boards. Many people find themselves pre-drilling their nail holes with particular brands and this can obviously slow down a project. Considering the benefits and the low maintenance costs (most brands have pretty good track records for durability).
In the world of Fiber Cement application most installers have added pneumatic nailers to their ever growing list of power tools. They speed up the installation process, making money for professionals. The question is whether purchasing one makes sense for the DIY.
In terms of improving efficiency, a reputable source figured that the nail gun fired 10-14 nails in the time it takes to hand drive one 2 ½ inch nail. That is roughly a 600% gain in efficiency. The numbers prove to be effective for a contractor and obviously similar efficiency gains transfer over to the DIY. Therefore we just need to address the financial advantages. In other words, is it worth spending the money on a gun if you’re doing a one time installation of 2000 sq ft. It will cost $780 for mid range equipment brand new. My local tool rental shop will provide the same equipment; a compressor, a hose and a gun for $45 a day.
Maybe that is the best comparison. There is little debate over whether the nail gun improves efficiency; it is just a matter of how much you want to spend in addition to the material cost. In my mind, $45/ day is well worth your time. In fact I think it is a great deal. If you don’t have a line up of projects that would validate purchasing a nail gun, then consider renting one for your next siding project.
