Marble sealing is the application of a penetrating or coating sealer to slow staining on porous marble. Sealers reduce staining but do not stop acid etching, which happens on contact.
DURAFLEX seals and protects marble across Sydney: the sealer prepares the stone, and DURAFLEX film is the optically clear physical barrier that completes it by stopping the etching a sealer cannot, at $450 + GST per lineal metre installed.
DURAFLEX installs marble protection across the greater Sydney region, covering suburbs from the Inner West and Eastern Suburbs to the Lower North Shore and Northern Beaches, from our NSW factory.
Marble sealing slows staining by soaking into the stone, but it cannot stop the acid etching that dulls marble on contact with wine, lemon or vinegar. DURAFLEX seals and protects marble benchtops across Sydney: a sealer to slow staining, then a clear film that physically stops the etching a sealer cannot.

What are we protecting?
Sydney kitchens are full of marble and natural stone, and every one of them should be sealed. A penetrating sealer soaks into the top few millimetres of the stone and slows how fast liquids are absorbed, which buys you time to wipe up a spill before it stains. It needs redoing every 6 to 24 months. For the full method, see our step-by-step guide to sealing a marble benchtop and the marble sealer reference guide.
DURAFLEX in action
Real installation: the DURAFLEX Beaumaris project.
Here is the honest limit every Sydney marble owner should know. Sealing slows staining, but it does not stop etching. Etching is not a stain, it is a dull mark where an acid reacts with the stone, and it happens in seconds whether the marble is sealed or not. No sealer prevents it. That is why sealing alone leaves your benchtop exposed to the most common way marble gets damaged.
The complete answer is two layers, working in conjunction. Nothing protects like a physical layer. Seal the stone to slow staining, then add DURAFLEX surface protection film, an optically clear, self-healing film that physically stops the etching and scratching a sealer cannot. It is CSIRO fire-tested to AS/NZS 1530.3, made from food-safe materials and backed by a warranty of up to 10 years. See marble sealing and the permanent alternative to sealing.
Our trained teams seal and protect marble across Sydney, from Double Bay, Woollahra, Paddington and Mosman to the wider Sydney area. Don't worry, it's DURAFLEX.
Sealing is priced by benchtop size and is a recurring cost, since a sealer needs reapplying every 6 to 24 months. Because a sealer cannot stop etching, most Sydney owners choose a one-time DURAFLEX film instead of, or alongside, sealing. Request an itemised estimate on this page.
Most marble kitchen benchtops need resealing every 6 to 24 months. Check with the water-drop test: if a drop of water left on the stone for 10 to 15 minutes darkens it, it is time to reseal.
No. Sealing slows staining but cannot stop acid etching, the dull marks wine and lemon leave. Only a physical film like DURAFLEX stops etching, which is why complete protection is a sealer plus film.
Yes, across Sydney and greater New South Wales, by certified, automotive-trained teams. Request an estimate on this page and the DURAFLEX team will be in touch, usually the same day.

A penetrating, or impregnating, sealer carries a resin into the pores of the stone in a water or solvent base. The carrier evaporates and the resin bonds inside the marble, leaving a breathable barrier that slows absorption without changing the look. On a working Sydney kitchen benchtop, expect to reseal every 6 to 24 months.
A coating sealer sits on top of the stone instead of soaking in. It can lift the sheen and it resists staining while intact, but it wears in traffic areas, can scuff or peel, and needs recoating. Most stone care professionals do not recommend a coating for a Sydney marble kitchen benchtop for that reason.
Protection film is an engineered sheet, around 150 microns thick, heat-sealed over the finished stone. DURAFLEX film is the option that stops acid etching in a Sydney kitchen, because the acid meets the film and never reaches the marble, and it is replaced at end of warranty rather than reapplied every season.
Penetrating sealers slow staining but do not stop acid etching from lemon juice, wine or vinegar. DURAFLEX film is a physical barrier, so the acid never touches the stone and etching cannot occur under the film.
Leave a drop of lemon juice on unprotected polished marble for 60 seconds and the dull etch mark is permanent. On marble fitted with DURAFLEX film, wipe it away and the surface is untouched. Etching is a chemical reaction with the calcium carbonate in the stone, not a stain sitting on top, which is why it happens whether or not the marble has been sealed.
DURAFLEX marble protection film is optically clear, so a Sydney marble benchtop still reads as the stone that was chosen.
DURAFLEX film rejects 97.5 per cent of UV, manufacturer batch-tested, which matters in harbour-facing kitchens with hours of direct sun.
DURAFLEX film is an engineered sheet around 150 microns thick, heat-sealed to the stone rather than painted on as a coating.
DURAFLEX ULTRA Satin-X is fire-tested by CSIRO to AS/NZS 1530.3 under report FNE13372, which covers fire performance only.
DURAFLEX installations carry a written warranty of up to 10 years, depending on the product and the application.
DURAFLEX film is made from food-safe materials, so it belongs on the surface where a Sydney household prepares meals.
| What you need | Penetrating sealer | Coating sealer | DURAFLEX protection film |
|---|---|---|---|
| Stops staining | Slows it; a spill still soaks in if left | Slows it while the coating stays intact | Yes, the film takes the spill instead of the stone |
| Stops acid etching | No | No | Yes, acid never reaches the marble |
| Stops scratching | No | Partly, until the coating wears through | Yes, and superficial marks in the film recover with heat on ULTRA Satin-X |
| Reapplication cycle | Every 6 to 24 months | Recoat as it wears | None; the film is replaced at end of warranty |
| Warranty, as published | Product-dependent, check what the provider publishes | Product-dependent, check what the provider publishes | Up to 10 years, written |
| Applied by | Owner or trade | Owner or trade | Accredited automotive-trained installers only |
The comparison is between product categories, not brands. Whichever provider you speak to, ask for the written warranty terms and who backs them.
