Following the decision by Work Health & Safety Ministers in March 2024, engineered stone has been officially banned in Australia from 1 July 2024. In its place, silica-free stone is now the go-to choice for homeowners seeking stylish and safer alternatives for their kitchen stone bench.
While silica-free stone offers many of the same aesthetic benefits as traditional stone look benchtops, there are important considerations when it comes to installation, maintenance, and longevity. Having worked in the cabinetry and benchtop industry for over 40 years, we’ve seen firsthand what can go wrong when homeowners don’t know the full picture.
Here are six things I wish I knew before installing a silica-free stone bench top in my own kitchen renovation project.
Tip #1 – Heat
Although silica-free stone can handle hot water, even boiling, it’s not as heat-resistant as natural stone. Placing a hot pot or tray directly from the stove onto your stone top benches can cause irreversible burn marks in the surface’s epoxy layer.
Additionally, UV rays from direct sunlight can fade colours and degrade the finish over time. Remember: always use heatproof boards, and be sure your installer allows for proper expansion gaps, about 5mm, to handle Australia’s temperature variations.
Tip #2 – Chipping
Like engineering stone, silica-free stone is tough but not indestructible. The edges of your kitchen stone bench, especially around under-mounted sinks or right-angle corners, are vulnerable to accidental knocks.
If you’re worried about this, consider opting for rounded edges like a bullnose profile. They’re far more forgiving against everyday kitchen accidents.
Tip #3 – Visible joins
All stone top benches, whether engineered stone or silica-free, require visible joins, especially in L-shaped layouts or large bench spans. Internal corners must be joined to prevent cracking due to tension from temperature and expansion.
While expert installers do everything possible to minimise visibility, matching glue colour and levelling surfaces, a faint line will always be present if you look closely.
Tip #4 – Overhang limitations
If you’re planning a breakfast bar or waterfall island, take note: any unsupported stone look benchtops overhang greater than 300mm will void most manufacturer warranties.
A 400mm overhang on a standard kitchen stone bench could weigh over 100 kilograms! Excessive weight or pressure could lead to cracks and serious safety risks. Always add proper supports if you want a larger overhang.
Tip #5 – Aesthetics
While all silica-free stone products are produced to high standards, some patterns and grain styles, especially the popular natural stone look benchtops, come with a higher price tag.
If you fall in love with a heavily grained colour or marble-look finish, be prepared for a price increase compared to solid colour options. The quality is consistent across all ranges, but you’re paying for the look and exclusivity of the design.
Tip #6 – More than just a bench top
Though most homeowners think of stone as purely for kitchen stone benches, silica-free stone can be used creatively throughout your home.
From boardroom tables and splashbacks to skirting boards, stair treads, and even custom furniture like fishpond surrounds or stone picture frames, its versatility goes well beyond the kitchen.
Final Thoughts on Caring for Your Silica-Free Stone Bench Top
Maintenance is simple but essential. Regular cleaning with warm, soapy water works best, avoiding harsh chemicals or acidic cleaners that could damage the surface polish.
Treat your new silica-free stone like glass: handle it with care, avoid sudden temperature shocks, and protect it from physical impacts. With the right care, your new stone look benchtops will remain a stunning centrepiece in your kitchen for years to come.
