For the tightest, water-resistant fit

Make sure your sustrate  fits perfectly and stays fixed – with clean-cut edges that align tightly when you use our purpose-made tools and accessories. The HardieBacker® Score-and-Snap Knife not only guarantees you cut HardieBacker backer board precisely,  but in record time as well. Extra strength screws ensure our impervious and strongest-on-the-market cement board stays fixed, with the power to hold up to 200 kg/m².
