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!
Pros: Easy to Install, Effective

Here are the 1st 3 panels installed. Make sure to stagger them to avoid 4 corners meeting at the same time as you lay the remaining panels (as indicated on the HardieBacker website).

Review 2 for HardieBacker 3 ft. x 5 ft. x 1/4 in. Cement Backerboard
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!
Pros: Sturdy, Effective
Cons: Difficult to Install

Review 3 for HardieBacker 3 ft. x 5 ft. x 1/4 in. Cement Backerboard
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.
Pros: High Quality of Material, Sturdy, Great Instructions

Review 5 for HardieBacker 3 ft. x 5 ft. x 1/4 in. Cement Backerboard
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.

Review 6 for HardieBacker 3 ft. x 5 ft. x 1/4 in. Cement Backerboard
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.
Cons: Difficult to Install, fragile, brittle

Review 7 for HardieBacker 3 ft. x 5 ft. x 1/4 in. Cement Backerboard
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.

Review 9 for HardieBacker 3 ft. x 5 ft. x 1/4 in. Cement Backerboard
used this to install tile in my bathroom floor. everything went well with no issues. My only complaint is that the grid stamped into the board for the measurements were off by about a 1/16th of an inch. not a big deal it just made cutting and breaking a little tricky at times.
Pros: Sturdy, Easy to Install, Looks Great

Review 10 for HardieBacker 3 ft. x 5 ft. x 1/4 in. Cement Backerboard
I found HardieBacker™ concrete board to be very consistent in size and quality. The new versions even have an embosed one inch grid on one side to make alignment easier. Of course, they have marks or indents where the fastening screws should be placed. Once layed with a thinset cement to glue it to your old surface, one has a nice even and level (or vertical in the case of 1/2 inch backer board on walls) surface to lay your tile. I use it for all tiling on walls, floors and counter tops.

Review 14 for HardieBacker 3 ft. x 5 ft. x 1/4 in. Cement Backerboard
I layed this down over my sub floor in my bathroom to lay tile down. It was easy to cut with a razor blade and easy to install. I used hardiebacker screws and thin set to lay it. Tiles stuck to this extremely well also.

Review 16 for HardieBacker 3 ft. x 5 ft. x 1/4 in. Cement Backerboard
I built a full shower in the corner of my basement. I built the shower area ( 3 foot x 3 foot ) and used this backer board on concrete block ,I used firring strips spaced 12 inches apart then fastened the backer board to the firring strips with drywall nails, the nails go right into it. I use my circular saw to cut the board,makes dust so use a mask. It was easy to cut,but I have seen previous posts that use a utility knife and score it. Sounded like too much work plus all the blades you up. I then useda latex adhesive to put up my 4 x 4 ceramic tile on it. Best thing I ever did ,it was so easy ,just square up the back board ( it has lines on the one side ). The tile was easy to glue on and was stright as an arrow. Glad I bought this instead of the concrete board which is very heavy and not really a smooth finish to lay your tile on. Trust me, this is the way to go as far as setting tile on. As I mentioned before I did space out my firring strips 12 inches because of the thickness ( 1/4 ") as oppossed to the 16 inch centers with the 1/2' cement board. I just thought it would make the backer board more sturdy,but that's just me.
Pros: Very Adhesive, High Quality of Material, Easy to Install

Review 19 for HardieBacker 3 ft. x 5 ft. x 1/4 in. Cement Backerboard
As complete amateurs, we found this board fairly easy to work with. A word to the wise for novices though: be sure the use a saw that is sharp enough! We went through about 12 blades doing 300 sq. ft. of floor.
