I wouldn't recommend a nail gun , but yes it's far as all the bad reviews on this product goes they're not true.., this stuff cuts easily with a diamond blade on a grinder, If you're over 60 you should probably enlist some help, YES it's heavy it's Concrete...try counter sinks and screws, you'll have a much better install and finished product.

HardiePanel HZ10 5/16 in. x 48 in. x 96 in. Fiber Cement Sierra 8 Panel Siding is rated 4.4 out of 5 by 16.
Rated 5 out of 5 by from hands-down the best siding product in the world In today's bland world of siding, my wife and I were looking for something different. Something paintable. Something for which WE can determine the colors, not pick from 9 shades of white. I sided a 32x52 barn with this stuff. Perfect. Currently siding my house with it. Lovely. Unless you love painting, buy it pre-primed. The extra cost is worth not having to put a coat of primer on. READ the instructions fully. Do it yourself according to the instructions or find a contractor willing to follow them. Do not take any shortcuts, do not let your installer take any, either. Any. Follow the best practices guide. Use the right nails. The manufacturer has awesome support -- you can call them with any question and they are happy to help.

However, several pieces were damaged in shipment. The installers putting up the siding have informed me that the product was not secured for transport correctly and quite a few of the sheets have damaged edges. This is not a product defect but a delivery one.

Rated 3 out of 5 by from Buyer Beware of it limitations I put up dozens of sheets of this 4x8 siding panel and I honestly cannot recommend it unless you have a lot of strength, a lot of patience and a lot of help. While it seems indestructible it is actually pretty fragile, difficult to cut, very hard to set nails to the correct depth and will turn to mush if allowed to get wet and stay wet. For me, a scrap piece laying on the ground outside basically dissolved within a couple of years. It is made up of layers of cement and fabric, not solid cement. So after it is installed, overdriven nails caulked and filled and every point of entry of moisture sealed, it will hold up as promised I am sure. The problem is achieving that. If this material gets wet and stays wet, it will not outlast wood in the same situation. Needless to say it needs paint to help seal it. Having said that, I would use the Hardi Lap siding in its place. It is easier to handle, easier to cut, can be blind nailed so those points of entry are eliminated and requires more centralized caulking which is easier to do. The biggest issues with the large panels is exposed nails, sealing seams and the unmanageable weight. Those issues are mitigated with the lap siding.

Rated 5 out of 5 by from Tip for undersink use I use this to protect the interior of the sink vanities and cabinets in my rental houses. It seems that no matter what you do, a sink will ultimately leak or the home's occupants will spill some of the most damaging "wet stuff" under there and you will struggle to make it look decent again. I've had to replace multiple vanities and cabinets before I used HardiePanel to protect them. No more. I cut a section of HardiePanel to fit (sometimes two sections if there is an obstruction) under the sink, place it smooth side up, screw it down, caulk with silicone on the edges, paint with a semi-gloss oil-based paint and the bottom of the vanity stays beatiful, renter after renter. Saves me $100's of dollars in time and money at move out or when they finally report a leak to me. My wife likes the look so much she wants me to do the same under our sinks.

Rated 5 out of 5 by from Great Product This is the best outdoor siding I have ever used, it cost a little more but you get what you pay for. Very durable and maintenance free.
