Going to lay cement board for new construction (floor and some walls). Manufacturer suggests using their screws but I thought the cost was ridiculous. Suggestions on using nails or other screws(don’t suggest drywall screws!!). Will be using thinset on back prior to fastening.

Carl, I use roofing nails and thinset on floors, durock screws on walls. Just make sure you sink the screw heads.
*I have the walls and floors screwed.
*Carl use the screws made for cement board. they are expensive but worth the money in the long run. No need to pre-drill pilot holes as with sheet rock screws and they hold better than nails. Just be sure your screw gun is set to drive them flush with the panel. Harry
*Carl' I would also suggest using construction adhesive on the back instead of thinset. Much faster to apply and adhesion is much stronger and won,t dry out as thin set will when applied to wood. Harry
*The last tile tub surround I did I used galvanized deck screws, at about 1/4 the price of the manufacturer's screws. 1/2 way through the job I vowed to get the expensive screws the next time (starting another one next week). Pre-drilling countersinks in the backer board wasted more time ($$$) than the upcharge for the proprietary screws. I felt I was stepping over the quarter to pick up a nickle...Definitely screw it vs roof nail it. It's just sturdier.
*Stray is right i went through the same thing. i decided to use screws and was to cheap to buy te ones made for hardibacker and went with some decking screws man after busting my but countersinking then screwing about 1/4 into the job i was just kicking myself. i went for screws because i thought about reversing the process if i or anyone else ever wanted to change the tile for something else. thats why i didnt go for nails. but do yourself a favor if your gonna use screws ..breakdown and use the right ones. you'll be glad you did.
*I use roofing nails out of a gun for 1/4" on the floor. Walls & tub decks I screw but I use Dens Shield on walls.
*Rob,I haven't used Dens Sheild before. Is it soft enough that you can use regular screws without a need to pre-drill countersinks in it?Local tile place said they used to carry it, but nobody bought it and they were stuck w/ some expensive inventory. They'd order it in for me if I needed quantity, but I never do jobs big enough to warrant it.
*It acts very much like drywall. i use galvinized deck screws to put it up. I don't normally use it on floors as I like 1/4" better. I doo have over 300 ft on my kitchen, bath laundry & hall. It has been there for over 4 years & my only complaint is with the tile from Florida Tile.
*b WBA At Your Serviceharryhow are you applying the construction adhesive, with a trowel with 100% coverage, or with a glue gun ?
*Tim, I use PL Premium polyurethane construction adhesive. It's applied with a caulking gun. I put a bead down each fastening pattern. Stuff is very strong and does not require 100% coverage. On one job I used it to attach 80lb pieces of granite to wood wall framing without any fasteners and 5 years later you would still need a big pry bar to get it loose. Harry
