I've been using hardie for several years now, I like it much better than Durock or Permabase. It's not anywhere near as messy, it's easier to handle and easier to cut. I use a grinder with a four inch masonry blade. I did find out something about it the other day. I put it around a fireplace and the only screws that were around were the type that used a #2 square head bit. The screws went right in without the slipping I have with a phillips. The only thing to watch out for on Hardie is not to get to close to the corner with the screws. When the screw head goes in, the corner of the board will break off, and more often than not, the corner will be pushed up, causing a little bump in the floor. Hardie with screws or screw shank nails is all I use anymore.

A couple of things to remember, when fastening Hardi keep them 3/8" away from edges and 2" from the corners. If you score-cut with either hand tool or side grinder, you first score the face then you snap UP, not down as you'd be inclined to do.

Hello everyone, new member here. I am a tile and stone subcontractor in colorado. I was interested to see some reviews on denshield(sp)it definitely does not seem like a product i would use ANYWHERE due to the gypsum core. In wet areas it requires more prep to completely waterproof, and as a floor substrate it must have a lower compressive strength than durock or hardi? I've seen it used more in this area, to my dismay. It may , however, be a step up from green board. I wont set to either. Anyone have anything good to say about this product?

It's easy to cut.

It's easy to cut.

That's too funny, guys! My sentiments exactly.
