Questions & Answers
What thickness backer board is good for floor tile?
We typically recommend the 1/4" HardieBacker board for floor applications, but the HardieBacker 500 and HydroDefence can be used if you need to make up additional thickness.
Could you please fix your Installation PDF for this product? Its simply maddening the way that the English and Spanish are intermingled, with the pages being out of order. Thanks!
Can I use this on a shower wall with 32 x 32 large format tile? I so, what tile adhesive is recommended?
Our backer board can be used with any tile weight 15 pounds per square foot or less when used with the required polymer modified thin-set which complies with ANSI A118.4.
Why is half inch not half inch
The board is a nominal 1/2" and it's exact thickness matches to the tapered mud edge of a 1/2" gypsum board.
Can I use SimplySet Thin set mortar in the ready to use container with the hydro backerboard ?
We require the use of a ANSI A118.4 modified thin-set mortar for adhering tile to the backer board. You would have to double check with either the manufacture or the container to see if the thin-set you intend to use meets ANSI A118.4
Can we paste on rough surface on wall of basement
No, we require it to nailed or screwed to the wall. We would require wood or metal furring installed to the wall if there is no framing.
Is there a 1/4” hardy backer with hydro defense ?
The only offering with the integrated HydroDefence coating is on our thicker backer boards, we do not offer a 1/4" version at this time.
Just confirming that this can be used for kitchen backsplash.
Yes, HardieBacker board can be used as substrate for kitchen backsplash tile.
