Customer Questions & Answers

Placing Porcine floor tile onto concrete in a garage turned family room. Do I thin set the Cement Board to the cement floor of the garage?

I'm assuming since the screws penetrate the cement board they will penetrate the cement garage floor as well. Is this a fact based assumption or should I used a different method?

When do you screw down the Hardie board to a plywood floor if you are trying to float out the unevenness of the plywood

floor? Wouldn't the screws conform the Hardie board to the unevenness of the floor that you are trying to correct without laying down a mud floor?
Asked by: EasyBreezy
I could write until my fingers fell off about this, but I'll control myself here. First of all, you've made a good point here. The HardieBacker installation specifications call for 1/4 in, HardieBacker to be set in a bed of thinset mortar, then screwed down. If you omit that mortar, all kinds of bad things happen. The mortar does not float out/correct all the unevenness of the subfloor. The fact that it naturally does some of this is only a minor, incidental benefit. When you start prepping a plywood subfloor floor for cement board and tile installation, you need to check for evenness with a four-foot level. You typically sand down the high spots in this step and patch the low spots. Only then do you trowel out the mortar bed, and lay the HardieBacker in it. And only after that do you screw the HardieBacker down. While, again, this process does help the evenness of the subfloor, the main purpose is to fill the voids under the boards and provide a monolithic support between the plywood subfloor and the cement board. After the HardieBacker is installed, you then trowel on another bed of thinset mortar and set your tile in it. Properly installed floor installation of HardieBacker, therefore, always leave the HardieBacker sandwiched between two layers of mortar. It's all a carefully designed support structure for the tile that you put on the floor. The goal is to avoid voids anywhere in this system that compromise the compressive strength of the whole structure and cause tile to crack. Here's the link to the HardieBacker installation specifications as a pdf. Usually, you can find a display of them right around the cement board stack in the store.

Rated 1 out of 5 by from Horrible product use Durock I've been installing for years and thought I would try this backerboard bc Durock makes a mess and can be crumbly. Bad decision it didn't score and snap easy at all. The screws were really hard to screw in. Laying this underlayment was a nightmare. Will not buy this again, I will use Durock !

Rated 5 out of 5 by from The best underlayment out there Ignore non pros that dont know how to use it Every pro kitchen and bath people I know swear by hardibacker . Durock and wonderboard suck . Buy the dewalt shears to cut it or just use a diamond blade on your grinder Pretty sure dewalt shears say 7/16 but it works on the 1/2 inch * hardibacker . I know because I use them. You can cut in doors with no dust its pretty cool for $175 ish .

Rated 4 out of 5 by from Good Product for Tile Underlayment It's a great product, and my company uses it regularly. A couple tips for the uninitiated: Be sure to mortar it down with thinset. That's what gives hardibacker its resistance to deflection. Don't screw too close to the edges as it's brittle. Leave a 1/16" gap between panels, and stagger the layout to keep from having 4 corners come together anywhere. Seam tape and thinset all of the seams where water is going to be an issue, otherwise it's not necessary. We use an autofeed screwgun with coated 1 1/2" screws, but hardiscrews will do fine. Good Luck!
