Durock Vs Hardibacker


Hello All

I was on a job today and my partner for whatever reason decided we were using hardibacker to line a tub. Normally we use Durock/wonder board so I'm not too familiar with the product. He said he grabbed it because he thought it cut easier and was lighter.

All in all I found it harder to score cut and almost twice as heavy. So my question is what is the advantage to using hardibacker in a tub/shower? If there is any. what about flooring? Maybe it's more of a flooring product?

Thanks!
Al

You will find more info on that in the tile section. The tile guys there have lots of good info on backing.

Re: Durock Vs Hardibacker


You found hardibacker twice as heavy as durock?
Oh well, if you scored and used that on a tub surround, you might as well continue on the floors, or just go back to what you're used to using, durock. I, like you, like to use things I'm familiar with and have use a lot. Good luck.

Hardibacker sucks the water out of your mastic. (That's a joke around here.) Out of your thinset. I dislike it for that reason. I prefer cement board. On the rare occasion I will use Hardi, it's because it doesn't bend as much when fastening so it can be floated with a little more thinset to make a curvy floor flatter.

It's all junk. Denshield is the way to go. Easier to install, and it's waterproof. There's not one advantage to hardibacker that I can think of. Use a urethane sealant to seal off screws and seams, like Wedi sealant or Sikaflex 221.

So denshield is waterproof? I finally found a place around here that I can get it. Going to try it for the first time on my current job (trying to save some $$$ on these tub surrounds. Been using Wedi)

It has a waterproof surface, cuts like drywall and installs easy. You need to screw every 6 inches, and since you seal the screwheads with a good sealant, you can use regular drywall screws. They aren't exposed to moisture or thinset.

Just read your other post under the Wedi system. Looks lie a pretty good idea! At about $2 a sqft for Wedi panels....it certainly begins to add up!

Oh yeah. Denshield is half the price of Wedi in my area, and frankly, I like working with it better. Just need the first foot to make that watertight bond at the corner, and then you seal the upper seam between the two different materials with Wedi and it's done.

Love the denshield......don't use anything but. Water proof seams and screws......no bevelled edges like durock or permabase so you got a perfectly flat surface to tile. Comes in 32" x 62" or 48" x 96" .......can't beat it. That being said I've never tried the hardi......Probly won't....thumbsup
