Engineered Stone Benchtop Protection Guide

Engineered stone, the quartz-and-resin surface sold under names like Caesarstone, Silestone, Essastone and Smartstone, has been the most popular benchtop in Australia for a decade. That changed in mid-2024. This guide explains what the change means for the benchtop you already own, what engineered stone genuinely resists, where it does not, and how to keep it looking new now that a like-for-like replacement is off the table.

Why protecting the one you own matters now

From mid-2024, the manufacture, supply and installation of engineered stone benchtops, panels and slabs containing crystalline silica is prohibited in Australia. The prohibition is a workplace-safety measure: the risk is the silica dust created when slabs are cut and fabricated, an occupational fabrication risk, not a risk from an installed benchtop in your kitchen. What it means for owners is simple: you cannot order a new slab to match, so the benchtop you have is no longer easily replaceable. Protecting it well is now the sensible move.

What engineered stone resists, and what it does not

Engineered stone is bound with resins that make it effectively non-porous, so it resists staining better than natural stone and rarely needs sealing. But non-porous is not the same as indestructible. Engineered stone still scratches from knives and grit, still dulls in high-use zones over time, and is more sensitive to heat than most people expect: a hot pan straight from the oven can leave a permanent mark or even crack the resin. Those three, scratching, dulling and heat, are exactly what a sealer cannot help with.

How to protect an engineered stone benchtop

Day to day, clean with a pH-neutral cleaner, use a board for chopping and always use a trivet under hot cookware. For lasting protection, DURAFLEX surface protection film is applied over the surface and takes the daily wear instead of the stone. It is an optically clear film, heat-sealed to the benchtop by automotive-trained specialists and backed by a warranty of up to 10 years. It has been fire-tested by CSIRO to AS/NZS 1530.3:1999, and the ULTRA Satin-X finish adds SGS-validated heat-activated self-healing for superficial scratches. DURAFLEX is the Australian originator of the surface protection film category, and engineered stone is a core part of what it protects. For the Caesarstone-specific routine, see our Caesarstone care guide.

The honest limits

Film is protection, not repair: it does not undo an existing chip or crack, though it can be applied over lightly marked stone once the surface is prepared, and it is not impact armour. What it does is stop the everyday scratching, dulling and surface heat marks reaching the slab you can no longer replace.

Frequently asked questions

Can I still buy an engineered stone benchtop in Australia?

No. Since mid-2024 the manufacture, supply and installation of engineered stone containing crystalline silica is prohibited in Australia. Existing installed benchtops are not affected and are safe to use, but they cannot be replaced like-for-like, which is why protecting the one you own matters.

Is my installed engineered stone benchtop dangerous?

No. The silica risk is occupational, from the dust created when slabs are cut and fabricated. An installed, sealed benchtop in a home poses no such risk. The prohibition is about protecting fabrication workers.

Does engineered stone need sealing?

Generally no. The resins that bind engineered stone make it effectively non-porous, so most manufacturers do not require sealing. It does, however, still scratch, dull and mark under heat, which a sealer cannot prevent.

How does DURAFLEX protect engineered stone?

DURAFLEX is an optically clear film applied over the benchtop that takes the daily scratching, dulling and surface heat marks instead of the stone. It is CSIRO fire-tested, heat-sealed to the stone at installation, made from food-safe materials and backed by a warranty of up to 10 years.
