Stone Sealer vs Protection Film: Which Does Your Benchtop Need?

A straight comparison of penetrating sealers, anti-etch coatings and our Stone Protection Film for engineered stone, natural stone and more.

By the Stone Film Syd. team ยท Updated

Quick answer

A sealer soaks into the pores and slows stains. It does not stop etching from lemon, wine or vinegar, it does nothing for scratches, and it has to be reapplied every year or two. Our Stone Protection Film is a clear physical layer bonded over the surface: it blocks stains and etching, resists and self-heals scratches, and carries a 10-year written warranty. Film is what we recommend on every surface we cover.

What a sealer cannot do

  • Stop etching. Acid reacts with the stone itself, and a sealer sits down in the pores rather than over the surface.
  • Stop scratches, scuffs or chips. A sealer adds no physical layer at all.
  • Stay put. Most penetrating sealers need reapplying every one to three years, and there is no visible sign when they stop working.
  • Do much on engineered stone, porcelain or non-stone surfaces, which are not porous enough to take a sealer.

An anti-etch liquid coating goes further than a sealer, but it is still a thin film of product that wears, can change the sheen unevenly and has to be stripped chemically and redone.

Where our film goes

  • Marble, limestone, travertine and onyx benchtops, islands, vanities and tables.
  • Granite, quartzite and dolomite, where the film handles stains, scratches and everyday wear.
  • Engineered stone and porcelain, including slabs already installed.
  • Selected non-stone surfaces. Send us a photo and we will tell you whether the film suits it.
  • Restaurants, bars, wineries and cafes with stone tables and counters.
  • Newly installed or newly restored surfaces you want to keep perfect, rentals, and homes being prepared for sale.

Gloss or Satin is your choice

Our film comes in Gloss and Satin. Neither is tied to a stone type. Most clients keep the original design intent, so Gloss goes over polished surfaces and Satin over honed, leathered or matte ones, but you can use the film to change the finish instead if that is the look you want. A polished marble island can go Satin, a honed benchtop can go Gloss. We bring samples so you can see both on your own surface before anything is cut.

What about DIY films?

Cheap adhesive vinyl sold online is not the same product. It is usually thinner, can look plastic, and is hard to lay flat around sinks and edges. Professional films use optically clear aliphatic polyurethane that stays flat and does not yellow, and are installed with trimmed, sealed edges.

Frequently asked questions

Is protection film better than sealing marble?
Yes. A sealer only slows staining and cannot stop etching at all. Our film blocks staining and etching, resists scratches, and carries a 10-year written warranty.
Do I still need a sealer if I have film?
No. The film covers the surface completely, so there is nothing left for a sealer to do. If an area is left unfilmed and you want it protected, tell us at the quote and we will include it.
Does it depend on my stone type?
The film goes on engineered stone, natural stone including marble, granite, quartzite, limestone and travertine, and on some non-stone surfaces too. Soft, acid-sensitive stones gain the most, but every surface we film gets the same stain, etch and scratch barrier.
How long does each last?
A sealer is reapplied every one to three years for the life of the benchtop. Our film is engineered to last 10 to 15 years and carries a 10-year written warranty.
Can protection film be removed?
Yes. Film can be removed by a professional without machining the stone, and damaged sections can be replaced.
