Stone protection film, explained

What it is, how it stops etching and stains, how it compares with sealers, how long it lasts and how to choose an installer in Sydney.

By the Stone Film Sydney team · Updated

Quick answer

Stone protection film is a thin, optically clear, self-healing polyurethane film applied over marble, natural stone and engineered surfaces. It works as a physical barrier: lemon juice, wine, vinegar, coffee and oil land on the film instead of the stone, so the stone cannot etch or stain, and everyday scratches are taken by the film. It comes in Gloss and Matte / Satin finishes, is installed without cutting the stone, and Stone Film Sydney's film carries a 10-year written warranty.

Key points

  • Stops acid etching, which sealers cannot do.
  • Blocks stains on porous stone such as marble, travertine and limestone.
  • Invisible when installed well, in Gloss or Matte / Satin.
  • Engineered for 10 to 15 years; removable without damaging the stone.

What stone protection film is

Stone protection film is a clear, flexible sheet of aliphatic polyurethane with a pressure-sensitive adhesive on the back and a self-healing top layer. Aliphatic polyurethane is chosen because it is UV stable and does not yellow, which matters on white marble and in sunny Sydney kitchens. The top layer lets fine everyday marks fade with warmth, so the surface keeps looking new.

You may also see it called stone film, marble protection film, anti-etch film, benchtop protection film or surface protection film. They all describe the same idea: a clear protective layer that sits on top of the stone rather than soaking into it.

What it protects against

ProblemWithout filmWith stone protection film
Acid etchingLemon, wine and vinegar dull marble, travertine and limestone within seconds to minutesAcids sit on the film and wipe away
StainsOil, coffee, wine and turmeric soak into porous stoneNothing reaches the stone to soak in
ScratchesSoft stones scratch from plates, grit and appliancesThe film takes everyday wear; fine marks self-heal
CleaningOnly pH-neutral stone cleaners are safeNormal non-abrasive household cleaners are fine

Film is not armour: it will not stop a knife cutting it or a heavy impact chipping an edge, so chopping boards and trivets are still recommended. Read more about why stone marks in marble etching explained.

How it is installed

Installation is precise, hand-finished work. The stone is deep-cleaned so nothing is trapped underneath, then the film is cut to each surface, around sinks, cooktops and edges, and laid with a wet-mount method so it can be positioned perfectly before it bonds. Most projects are completed in a single day, and commercial venues are done after hours with no downtime. The stone is never cut or ground, so there is no dust. See our installation process.

Gloss or Matte / Satin

Both finishes give identical protection; the only difference is the look. Gloss is mirror-clear and deepens colour and veining on polished stone. Matte / Satin is soft and low-sheen, suiting honed, leathered and brushed stone. Most people match the finish they already have; some use the film to change it. We apply samples of both to your own stone before you decide. Compare the finishes.

Which surfaces it suits

Stone protection film suits almost every benchtop and table material, including marble (Calacatta, Carrara, Statuario and more), travertine, limestone, onyx, quartzite, dolomite, granite, Caesarstone and engineered stone, porcelain, sintered stone, terrazzo and concrete. It is used on kitchen benchtops and islands, splashbacks, bathroom vanities, dining and coffee tables, bar tops, reception desks and hospitality counters. See every surface we protect.

How long it lasts

Our film is engineered for 10 to 15 years of everyday use and is backed by a 10-year written warranty. If a section is ever damaged, it can be removed and replaced by a professional without machining the stone.

What it costs

There is no single price per square metre that fits every job. Cost depends on the total area, how many separate pieces and joins there are, sink and cooktop cut-outs, waterfall ends and edge profiles, the finish and access. Stone Film Sydney gives free, detailed quotes on site or over the phone. See what drives the price.

Already damaged stone

Film protects the surface as it is on the day it is installed, so etched or stained stone should be restored first. Our stone care guides explain each type of damage, and we can advise on the order of works before we protect it.

Choosing a stone protection film installer in Sydney

Several companies install stone protection film in Sydney. Whoever you choose, ask about:

  • Optical clarity: ask to see the film on your own stone, in your own light.
  • Edges and joins: where seams will sit, and how edges and cut-outs are finished.
  • Warranty: how long, what it covers, and whether it is in writing.
  • Finish options: both Gloss and Matte / Satin, matched to your stone.
  • Experience with your stone: marble, onyx and travertine each need a slightly different approach.
  • Commercial scheduling: after-hours installation if you run a venue.

Stone Film Sydney installs across Greater Sydney, from the Eastern Suburbs and North Shore to the Hills and Sutherland Shire, with samples of both finishes at every on-site consultation and a 10-year written warranty. See recent projects or learn about us.

Frequently asked questions

Stone protection film is an optically clear, self-healing polyurethane film applied over marble, natural stone and engineered surfaces. It forms a physical barrier, so acids, stains and everyday scratches meet the film instead of the stone.
Yes. Etching happens when acid touches calcite. Because the film covers the stone, lemon juice, wine and vinegar never reach the marble, so it cannot etch where the film is applied.
A well-installed film is optically clear with no orange-peel texture. Stone Film Sydney matches the sheen with Gloss or Matte / Satin film, so most people cannot tell it is there.
Stone Film Sydney's film is engineered for 10 to 15 years of normal use and comes with a 10-year written warranty.
They do different jobs. A sealer slows stains but does not stop etching and needs reapplying every one to three years. Film is a barrier over the surface that stops etching and staining and resists scratches.
Yes. It can be removed by a professional without machining the stone, and damaged sections can be replaced.
The film is highly heat resistant, but as with any benchtop, use a trivet for pots straight off the stove.
Price depends on the area, the number of pieces and joins, cut-outs, edges and access. Stone Film Sydney gives free, detailed quotes on site or over the phone.
