Thank you all for your replies.
I am using the HardiBacker Cement type board for the floor, 1/2" Its on top
of 3/4" T&G Plywood on top of the Manufactured I Beam Joists.
the Screws I've uses are 'special' for the backer board. They are in the
Tile section at Home Chepo. Supposed to have some barb type fins on the
underside of the head to help counter sync the screws.
They are Philips, and I've either stripped the head or Broken the bit trying
to get them counter sunk.
We've used Cordless, and corded Drills. The best was actually a low speed,
High tork Right angle drill. Well after predrilling the holes the Makita
18v Cordless was fine.
Thank you again for your replies!
For the novice without access to a power nailer (electric or air
driven), nailing any Hardi product is an invitation to disaster. home
handiperson NEED to stick with screws and pre-drill with a carbide
tipped drill bit.
Way to easy to miss the nail and BANG the Harid product, fracturing off
the corner, forcing you to remove the product piece entirely and start
Pro installers can do this with their power equipment. Folks who have
done this over many many jobs can swing a 16oz hammer JUST right to make
this happen without damage to the board. The rest of us MUST stick with
screws, else we face disaster.
James Hardi product?
Maybe so but I sure could not get those screws to countersink with the
equipment I had.
I have laid a lot of it with nails and never had any problem like you
describe. The hardest part I thought was to hit it hard enough to keep
the head flush and it is one hell of a lot of nails.
