Rated 5.0 out of 5.0 by NoContractors Easy to install over old subfloor!
I needed to do a 425 square foot tiling job. The subfloor was 2 layers of 3/4" plywood (for a total of 1-1/2" thickness), which was nailed/screwed to floor joists. This subfloor was still strong, but it was old, dirty, wavy, and a bit rotten at the surface. I replaced the most rotten sections of subfloor to be safe, but could not afford to replace the whole subfloor. I also could not afford to clean the subfloor via sanding. So, these HardieBacker boards saved the day! These boards are secured to the subfloor with both thin-set AND corrosion resistant screws. The thin-set helped to level the wavy areas, and the screws ensured a secure attachment to the subfloor in the dirty locations. Here are the exact materials I used: 1) This hardiebacker board Model # 220022. 2) Thin-set mortar Model # CBTSG50 (to bond the hardiebacker board to the subfloor). 3) Corrosion resistant cement board screws Model # 23410. 4) Thin-set mortar Model # MTSG50 (to fill the gaps between the hardiebacker board and to bond the tiles to the hardiebacker board). 5) 2" cement board tape Model # FDW8246-U (this tape is pressed into the wet thin-set mortar when filling the gaps between the hardiebacker board). IMPORTANT NOTES: 1 bag of thin-set mortar provides JUST enough material to lay 4 hardiebacker panels. 150 screws are JUST enough to secure 3 hardiebacker panels. The official HardieBacker website has awesome videos to guide your installation. Good luck!

Rated 4.0 out of 5.0 by RMTW 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!

Used this backerboard under about 500 square feet of tiling. Having never tiled before this was easy to use.

As a tile setter I use this product just about daily, and it is by far the best cement board to work with. It's lighter and much easier to cut than Durock and similar products, not to mention much easier to see your cut and layout lines on.

I used this to cap a shower curb made of 2x4s. This was my first time using cement boards. I had trouble using the snap method for pieces narrower than 4". Even when it did work, the edges were more ragged than I wanted. I also used a jig saw to cut pieces out (wearing a dust mask and outside). A blade with large teeth worked best.

For those that use the thinner backer board, you can break it over a sharp edge instead of cutting which saves time. Then use the mesh tape to cover seams.

Not sure why Hardy board is cheaper than regular backer board because its much better quality. It cuts easier, has a smoother surface along with an imprinted grid finish that helps tile to adhere. This is definitely the right choice.

Rated 1.0 out of 5.0 by George Cracker Board
I was used to traditional 1/2" cement board but saw this light weight, smaller board and thought this 1/4" board looked great. I liked the markings and overall appearance, but found it very difficult and fragile. When screwing it on place for a shower conversion, it often cracked and disintegrated. I was cutting an opening for a light switch and the panel broke in three pieces. I now call it "cracker board".
I won't touch this stuff again.
