1/2 in. x 3 ft. x 5 ft. Cement Board is rated 4.0 out of 5 by 4.
Rated 5 out of 5 by from This is the easiest to work with cement board I've... This is the easiest to work with cement board I've come across. Simply score it with a utility knife and snap it, just like drywall. If you use screws designed for cement board they countersink easily and do not leave a huge bump like Hardibacker. It's also not going to swell up and delaminate if it gets wet like I've had happen with Hardibacker. I also like that it has an aggressive texture to it which seems like it will grab the thinset mortar better.

Rated 4 out of 5 by from PermaBase Cement Board I used PermaBase for a shower stall remodel and used HardiBacker for the bathroom floor and sink back splash. The advantage of the PermaBase is that it scores more quickly and comes in smaller sheets that are not as heavy. I'm not a weight-lifter but I was able to maneuver the PermaBase sheets pretty well on my own. Working on a ladder and applying this to the shower ceiling, I was glad to able to lift a 3 x 2.5 panel fairly easily. The draw back, oddly, also involves the scoring. It scores quicker, but a little "rough" and you have to cut through the mesh that holds all the components in place which takes some getting used to. It's fairly solid material, but crumbles a bit when you're making a tight fit. It went into the studs very easily with the correct backer board screws. It took stone 4" tiles and mosiac with no problem (even on the shower ceiling). I may switch to HardiBacker on the next shower stall, only because the larger sheets could help me avoid a horizontal seam or two. But the lighter weight of the PermaBase is still appealing. Kinda on the fence as to which I like better. I'd definitely go with HardiBacker for floor or counter top applications, though. It seems tougher, more solid and I believe it's recommended for these applications.

Rated 4 out of 5 by from Good stuff but be careful putting it on walls I am just completing a bathroom remodel with tiled shower surround and floors. This is the first time I've used PermaBase Plus. In the past, I've always used 1/2" Durock CBU's without any problems. The PermaBase is definitely lighter and easier to handle. Cutting was fairly quick and simple. I just used a utility knife to score the line and snapped the board like you would with drywall, then run the knife up the crease on the backside (you'll go through blades pretty fast). Cuts were clean and if you do need to clean up a cut or take some more material off the cut then just use a rasp on the edge. Easy. I really liked the fact that I could drive a screw close to the edge without the disintegrating. One warning. This product has more flex than traditional CBU's. Not noticeable when installed on floors but on the wall. After installing the first shower wall, I noticed a good amount of flex when I pushed on it between studs. More flex than I am comfortable with. The manufacturer and other pros said it would stiffen up once all the seems were properly taped, tile installed and grout hardens. Just to be safe, I added additional blocking support between the studs...midway up the board and at the seems. The framing around the shower was spaced 16" oc but some of the cavities were spaced closer together. Those spaces less than 16"oc were firm and did not need additional support. Only those spaces that were a full 16"oc did I add support. Easy fix and it did stiffen it up to my satisfaction. Good stuff just make sure you add additional support between studs.

Rated 3 out of 5 by from Almost as good I like Permabase because it looks nice compared to Durock or Wonderboard. I would rate it 2nd behind SelectCrete, but I can't find SelectCrete in the Midwest. That board is the easiest and cleanest to score and snap, lighter weight, and has the best edge. But since I can't get that in Ohio, I've been using Permabase and it's almost as good.
