A warranty with no end date
Duraflex offers up to 10 years. Ours lasts for as long as the film stays on your stone. For a benchtop you plan to keep for decades, that difference is the whole point.
Film comparison
Stone Shield
vs Duraflex.
Two stone protection films, both made to stop etching and staining. The difference is in what each one is rated to and what each warranty promises. Here are the published numbers, side by side.

Why it matters
Where the gap
actually shows.
More headroom on heat
Our film is rated to 250°C against Duraflex’s stated 230°C, and loss of heat resistance below that rating is covered by our warranty.
Adds to what you sell
Sell the house and our warranty goes with it, free. Duraflex states its warranty is non-transferable, so it ends with the original buyer.
No bill to make a claim
If something covered goes wrong, we pay for the materials, the labour and the visit. The business that installed it is the business that fixes it.
What is the difference between Stone Shield and Duraflex?
Both are protection films that sit on top of natural stone to stop etching and staining. On the published figures, our film is rated to 250°C against Duraflex’s stated 230°C, our warranty is lifetime against Duraflex’s up to 10 years, and ours transfers to a new owner while Duraflex states its warranty is non-transferable.
Is Stone Shield Sydney part of Duraflex?
No. Stone Shield Sydney is an independent Sydney business. We are not affiliated with, endorsed by or connected to Duraflex.
Which film has the longer warranty?
Ours. Stone Shield film comes with a lifetime warranty, for as long as the film stays on the original surface. Duraflex advertises a warranty of up to 10 years.
Which film handles more heat?
Our film is rated to 250°C. Duraflex’s warranty states a maximum of 230°C. With any film, we still recommend a trivet for cookware straight off the stove or out of the oven.
Can you remove existing film and install yours?
Often, yes. We assess the surface first and tell you honestly what is involved before any work starts.
