Customer Questions & Answers

How many screws needed for 1 sheet of hardie backer?

I guess my first question was not specific enough. The Hardie Backer Material is manufactured with dimples in the face of the material at the spacing which you are supposed to screw the material to the subfloor. What is this spacing, and/or, how many screws would it take to attach one piece (3'x5') of material to the subfloor if one uses every provided screwing location? This would be important information, since you could order the correct quantity of screws, based on how many sheets of hardie backer you need (which is based on your project square footage).

You could use these or you 1 and 3/4. Either would provide you with enough grab and depth.

Quantity of screws per sf of floor?

How many screws go in say one sheet of 3'x5' hardie backer material? How can I quickly determine how much coverage I get from a 150 pack versus a 600 pack?

Rated 5 out of 5 by from Great product I am a professional tile-setter who uses this product all the time. The person having all the problems with the self-starting and countersinking complaints cannot be using an impact drill. (they are essential for installing cement board.) We have tried a variety of similar square head screws available from different manufacturers but these, unlike others: 1.) Fit snugly. They stay on the bit (so you can load your screw and punch it into the board to start it) 2.) Are cut more accurate so the tips bite in without falling over or spinning in place. 3.) Are more rarely filled with coating in the square head (though still a few in each box) 4.) Save time! (for all the above reasons) 5.) Are reasonably priced All these things matter. A lot! We now use these exclusively.

Rated 5 out of 5 by from Did the job I used these in a bathroom remodel. I left the ~10 year old existing hardie-backer in place and cleaned it up. One of the problems with the previous tile job was cracking grout lines. I saw why when I pulled it up. I put about 40 more screws in the 5" x 5" space to strengthen the floor. With my impact driver, I was able to get every screw dug in and counter-sunk well. The square bit was key.

Rated 1 out of 5 by from Disappointing When I was in the store buying HardiBacker I saw these and thought, "oh, good, these will be perfect," so I bought a box. They claim to be self-drilling. I say, not so much. I have to get the weight of my body behind the drill and push hard to get these things to self start. In an awkward position, like overhead where I have to push with just my arms, they just spin. They claim to countersink themselves. Again, not so much. Each time I drove a screw home I had to back it out to brush compacted debris out from under the screw head, then drive it back in again to get it to actually countersink, and even then I don't think it really went deep enough. Also, each time I drove a screw home it had a tendency to lift the panel away from the stud just a bit. I would have to back the screw out far enough to let the panel press back against the stud, then drive the screw home again to get the panel to lay flat. Lastly, when the screw bottomed out, more often than not the square drive bit would cam out of the head. It didn't matter if I used their bit or one of my own. This further undermined the effectiveness self-countersink feature. When I used up the box, I used philips-drive coated deck screws to finish the job. They actually worked better.

Rated 3 out of 5 by from Not Ideal I'm a pretty handy guy, but this is my first experience with cement board and with these screws. Specifically, I was putting down 1/2" Hardiebacker (which is actually 3/8") with the 1 5/8" cement board screws with my impact driver, using the new bit that came with the screws. I had trouble in several areas: 1) They're supposed to go right in, but I had to work at it (use all my weight, and still they'd only grab after a lot of spinning). 2) They're supposed to counter sink into the cement board and get flush, but about every 10th screw, more as time went on, wouldn't get flush. 3) On those same screws, the head would get stripped out as I tried to get them flush--the square holes ended up becoming round holes. I have another piece of board to screw down, so I'll try a couple of things. Some other suggestions I've heard are A) to pre-drill each hole, or B) to screw in the screw 3/4 of the way or so, then back it out, brush away debris, and then go in all the way. or C) to use a countersink bit (or star bit) to help the head countersink in properly. That's a lot of work, though, and that tool is going to dull up fast. I'm inclined to get a new bit and then try B.

Rated 5 out of 5 by from Only way to do it! The BackerOn board screws worked perfect. It is easier to counter sink the head if you use an old drill bit to make a starter hole.
