Customer Questions & Answers

HardieBacker for the whole basement walls

Can I use HardieBacker 500 for the whole basement walls? The ceiling will be regular drywall but I am thinking using HardieBacker for all the foundation walls. Instead of putting tile on it, I will just paint the hardiebacker just like drywall. Will this cause any problem in the long run, such as cracks?
Asked by: Johnny
I called James Hardie tech support because I had the same question. The rep I spoke with said as long as there's framing to attach it to, it will work just fine. Not sure why they couldn't have said that here.
