HardieBacker boards are cement backer boards for tiles and stone and are a direct replacement for plywood and plasterboards. HardieBacker boards are designed to be used anywhere were tiles or stone are fixed, this can be both on walls or floors. Hardiebacker boards are dimensionally stable surface which means they don’t warp, swell, rot or even deteriorate in even the wettest conditions. HardieBacker also contains Mouldblock technology which gives amazing mould resistance.

Using plywood and plasterboard can lead to tile failure due to their breakdown or swell which can in turn lead to tiles or grout cracking or even tiles coming loose, HardieBacker outperforms any other substrate and also increases the weight maximum weight that can be hung on walls.

HardieBacker comes in two thicknesses; 6mm for over boarding wooden floors and 12mm which fastens directly to wooden framed walls. The 6mm HardieBacker boards for the floor are considerably thinner than using 18mm plywood which helps minimise the transition between floors.

Reasons for HardieBacker over Plasterboard:

When Plasterboard meets moisture… it can

  • Rot Plasterboards contain a gypsum core. They retain moisture and can disintegrate, eventually causing tiles to become unstuck.
  • Grow mould The paper facing of plasterboards can serve as a food source for mould.
