  • Nailing Hardi-Backer

    I'm contemplating using 2 3/8" galvanized nails out of the paslode to put down hardi-backer rather than screwing it down due to the speed. Has anyone ever done it had any pros cons?

    The only nails you can use are galvanized roofing nails.

      what exactly is the reasoning on being able to use galvanized roofing nails and no other galvanized nails?

        The same reasons you don't roof with 8d commons.

              SMT,

              If you want to do work like that you should keep it to yourself. Staples of any length or gauge are NOT an approved fastener for Hardi.

              Since apparently we all have computers here, why don't all of us use them to find what the manufacturer has to say?

                It seems you are wrong in this case if you're using them for countertops than staples are an approved fastener. You are correct as far as staples for using Hardie on the floor.

                For countertops:
                Minimum 3/4" long corrosion-resistant roofing nails.
                Minimum 3/4" long ribbed counter sinking corrosion-resistant screws.
                18-gauge corrosion-resistant polymer coated 3/4" staples with a 1/4" crown.
                For 1/2" HardieBacker cement board, use minimum 1-1/4" long corrosion-resistant roofing nails or ribbed countersinking screws.

                Straight from the website.

                  Correct me if I am wrong, but I am pretty sure that staples are not a recommended fastener for cement board. Screws or roofing nails are the recommended ones. The reason for roofing nails is the bigger head, and I don't think you want anything longer then inch and a half. I use a coil roofing gun for putting cement board on floors with inch and a quarter nails.

                    Well I checked into my own question and they recommend roofing galvanized roofing nails as long as they don't penetrate the subflooring. So it all depends on the thickness of the backer and the subfloor as to what you can use.

                      Miller,

                      Where did you find that info?

                      "For countertops:
                      Minimum 3/4" long corrosion-resistant roofing nails.
                      Minimum 3/4" long ribbed counter sinking corrosion-resistant screws.
                      18-gauge corrosion-resistant polymer coated 3/4" staples with a 1/4" crown.
                      For 1/2" HardieBacker cement board, use minimum 1-1/4" long corrosion-resistant roofing nails or ribbed countersinking screws."

                      Is that old info? It's not on their current site and I don't remember it being in their pamphlet.

                      They recommend min. 1 1/4" fasteners on floor, actually I think they like it when the fastener penetrates the subfloor a bit.

                        Here is the site I got it from that stuff is about 3/4 of the way down then the one about the fasteners not penetrating the subfloor is about 1/2 way down.

                          the staples are there only to hold the backer in place until the thinset sets up. all of the fastener guidelines you quote are for fasteners only with no thinset. with 95%coverage on the thinset you don't even need fasteners but i staple them to hold position.

                            I gave you a plenty detailed and correct answer assuming you are a builder who ever put a shingle on a roof or at least read the manufacturer's fastening schedule printed on the bundle.

                            Glad you were able to confirm.

                            As to spec'd fastener length when installing boards on sub floors, the idea is to attach the backer only to the ply, not to the joists.

                              Let me clarify I was just asking about it. We always just screw it down and I was asking about nailing. We used screws as per manufacturer instructions. I never even checked the directions about nails until last night and saw that galvanized roofing nails were in fact an approved fastener. You learn something new everyday.
