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.

    Easier to use than Wonderboard. Goes down faster and easier modify and fit in tight spaces.

    the backer board is fine. I used my rotozip to cut it with a diamond blade. easy to cut and handle. I have never had much luck cutting this stuff with a razor knife.

    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.
