Great Product
I purchased about 300 of these hardie backer boards for a condo in la, sound engineer required me to install double of these, they were great a light enough to carry and move around, easy to cut and place on the floor, I anchored some down with concrete screws and didn't break good material.

easy to install and cut
my favorite cement board. It would be perfect if they add a mark line for each 8" it will make screwing the boards in little faster.

I've used this product in dozens of bathrooms, behind tub and shower walls but this time, I decided to use it on something totally different. I installed below a few bay windows on an old house, where there had previously been some of that old-fashioned criss-cross, wooden lattice. I took the lattice down because the varmints kept crawling behind there to keep warm at night. They also had a habit of tearing it apart as a way of saying "Than you" for the free nights lodging. So, I decided to use concrete backerboard instead and I painted this boards a flat black with BEHR brand exterior paint. This would not only send out a "No Vacancy" message but it would keep the cold off of the floors in the bay windows in the winter months. This was a very simply and inexpensive fix.
