Before you try anything: always speak to a professional before cleaning, treating or applying any product to your stone. Every slab is different, and the wrong product can cause permanent damage. Contact us or a qualified stone restorer first.
Quick answer
Porcelain is non-porous and does not etch, so film is not about acids here. Polished porcelain shows scratches and grey metal marks, and the decorative pattern is on the surface, so deep scratches and chips expose the body beneath. Clear film protects the printed surface from everyday scratches and marks and keeps a polished finish looking new.
Key points
- Porcelain does not etch or absorb stains.
- The marble look is printed on the surface, not all the way through.
- Polished glazes show scratches and metal marks.
- Film takes the everyday wear instead of the print.
Why porcelain is different
Porcelain benchtops are made by pressing fine clays and minerals into thin, large slabs and firing them at very high temperatures. The result is dense, non-porous and chemically resistant, which is why porcelain became a leading benchtop choice after the engineered stone ban. Lemon juice and red wine do nothing to it.
The pattern, whether it imitates Calacatta or Nero Marquina, is digitally printed onto the surface before firing. In many slabs the colour does not run through the body. A scratch through the glaze, or a chip on an edge, shows a lighter or plainer material underneath that cannot be polished back.
Where film makes sense on porcelain
We are straightforward about this: if your porcelain is matte and lightly used, it may not need anything. Film is most useful on polished porcelain, which shows fine scratches and grey marks from pots and cutlery, on dining tables and islands that see constant plates and glassware, and on commercial counters.
